I absolutely hate the big bang theory!?

Question

What sense does the big bang theory make? The universe started off as something as small as an atom. Ok, where did that come from? Where did this atom come from? Where did god come from? I know its a loaded question but, the universe started off as a little atom and blew up. Okay that tells me nothing. Thats like taking a big problem and making it bigger and calling it a theory. How do scientists get away with that? Why can't they just say, "we don't know." ?? Can anyone elaborate non-stupidly on this subject?

Okay, I've watched almost every show on the history channel on it. Repeatedly, and it explains nothing. Just the stupid theory and it doesn't explain nothing. Thats like saying, this sand came from this bigger rock, the big rock came out of the sky from an asteroid, the asteroid came from the big bang theory. Great... where did the stupid atom originate. I am watching the history channel just like all of you... believe me...

Answer 1

First of all, stop trying to get reputable information from The History Channel. It's their job to make money, not educate.

Secondly, there's a reason that understanding the Big Bang isn't in junior high school syllabuses. To know it happened can be learned. To understand what it means requires a career of theoretical and mechanical physics.

For a start, though, the Big Bang was not literally an explosion. And cosmologists do regularly say "We don't know". Everything can be known according to the laws of physics, assuming our understanding of them is correct, back to a certain time. That time is a tenth of a thousandth of a millionth of a billionth of a trillionth of a trillionth of a second after the beginning of the expansion that we call the Big Bang.

Before that, the laws of physics as we understand them don't apply. That's the bit about which physicists and cosmologists say "We don't know". They have theories, which they test every time a new understanding or discovery comes about regarding the laws of physics, but that's all.

So, what they don't know is about an extremely short time. By all means, tell them you're not happy that they haven't solved the ultimate mystery. But how about credit where credit's due? Congratulate them also for what they've managed to deduce about the 14-or-so billion years since that unimaginable fraction of a second after the beginning.

Answer 2

They can't say "we don't know", because that would be admitting that there are things in the universe that cannot be explained through science alone, and admitting that you don't know does not get you grants or jobs in the scientific world. And the big bang theory doesn't have the entire universe starting off as "one little atom". It is simply all the mass that is in the universe was concentrated into one small point (small being relative only to the size of the universe), much like a black hole can have the same mass as a star but be millions of times smaller. At some point this collection of matter or energy (no one can be sure which it was, because matter and energy are one and the same at a fundemental level), met with a catalyst that forced it to explode, creating the universe. I am afraid that for your God question you will only get "stupid answers" because unlike science, it is a matter of faith and can only be explained as God always has been, is, and always will be present. The "big bang" theory does not exclude God, though, as many scientists will claim. Instead, it shows that there must be another higher force out their for a concentration of particles to suddenly react with one another, after scientists own estimations of an eternity of being stable. Whether you choose to believe that or not is your business. But sometimes you have to be willing to accept the "stupid answers" if you want to be satisfied.

Answer 3

While the reasons for the origin of the universe are unknown, there is a lot of evidence that the Big Bang was the event that originated the universe. E.g., the Cosmic Microwave Background, the ubiquitous radiation that is observable in all directions, the residual energy left from the first few days after the big bang. One of the most dramatic validations of a scientific theory was the COBE experiment, which measured the cosmic microwave background and found it to be a nearly perfect blackbody spectrum, as predicted by the Big Bang theory. The CMB is the product of a big bang; whatever led to that event, that most probably WAS how the universe began. The Big Bang makes many other predictions for the evolution of the universe, all of which are well-validated by observation, such as the distribution of elements, red-shifting of light from distant galaxies, the age of the observable universe, etc.

So, none of this **** is pulled out of thin air. Yes, there are unanswered questions, like "what came before this?", but as a cosmological model, the Big Bang is pretty solid science.

I should add: you want answers to the question of what caused the singularity proposed by the Big Bang. Well, so do most scientists, but current scientific theories are unable to answer this question (as readily admitted). General relativity breaks down; the fundamental forces break down; time itself has no meaning in the singularity. So our current scientific framework can't answer the question you're posing. And they DO say this. It is a fundamental feature of the theory; however, as I said above, there's quite a bit of evidence that this singularity existed.

Answer 4

Why can't the scientists explain it in a way that makes sense to common people... for all we know they may just be making up their science language- no offense to anyone. I know, they are really smart and do a lot of good things b/c of it. Is it really too hard to at least explain to college-level students how it works?

It's supposed to be a theory, but i'm pretty sure they have shows on the discovery channel based on it. (i think its called Universe, not sure) maybe I need to watch them...

Answer 5

Exactly! I've always wondered how scientists determined that the universe was suddenly conjured up by an exploding atom that gave the very breath of modern civilization--that and evolution are my enemies. But then again, I also heard theories of God possibly causing the "big bang", hence from the book of Genesis in the New Testament, "And God said 'let there be light'.". Personally, my being a devout Christian, I 'know' that God created existence...but as how, obviously no one can determine, and no one ever will be despite how powerful or intellectual may they become; no one ever knows until it's all over. (and to get off of the subject a little, Sylvia Browne says it will be only about 95 more years). I hope this was more of a personal-opinionated question rather than a bias answer, apologies if I offended anyone who reads this.

Answer 6

When it was discovered that all galaxies are moving away from each other it was logical to conclude that one time they must have all bunched closer together, but there are some disturbing discrepancies in the manner the theory has been modified over the years. The original theory traced the galaxies back to a singularity that had a life span of 10-43 second. Later claims were made that this pin point of pure energy actually did not create any matter for a period of 600,000 years. If this is correct it would have been a flawed process that was used to obtain the original observation, instead of a singularity, a galaxy sized bubble of pure energy should have been detected, they can't have it both ways. Another thing that really bugs me is the total lack of effort to determine where this energy came from. I don't hate the theory, it is just unsatisfying the way it has evolved.

Answer 7

We certainly know that our universe exists, however, this knowledge alone has not satisfied mankind's quest for further understanding. Our curiosity has led us to question our place in this universe and furthermore, the place of the universe itself. Throughout time we have asked ourselves these questions: How did our universe begin? How old is our universe? How did matter come to exist? Obviously, these are not simple questions and throughout our brief history on this planet much time and effort has been spent looking for some clue. Yet, after all this energy has been expended, much of what we know is still only speculation.

We have, however, come a long way from the mystical beginnings of the study of cosmology and the origins of the universe. Through the understandings of modern science we have been able to provide firm theories for some of the answers we once called hypotheses. True to the nature of science, a majority of these answers have only led to more intriguing and complex questions. It seems to be inherent in our search for knowledge that questions will always continue to exist.

Although in this short chapter it will be impossible to tackle all of the questions concerning the creation of everything we know as reality, an attempt will be made to address certain fundamental questions of our being. It will be important to keep in mind that all of this information is constantly being questioned and reevaluated in order to understand the universe more clearly. For our purposes, through an examination of what is known about the Big Bang itself, the age of the universe, and the synthesis of the first atoms, we believe that we can begin to answer several of these key questions.

THE BIG BANG
One of the most persistently asked questions has been: How was the universe created? Many once believed that the universe had no beginning or end and was truly infinite. Through the inception of the Big Bang theory, however,no longer could the universe be considered infinite. The universe was forced to take on the properties of a finite phenomenon, possessing a history and a beginning.

About 15 billion years ago a tremendous explosion started the expansion of the universe. This explosion is known as the Big Bang. At the point of this event all of the matter and energy of space was contained at one point. What exisisted prior to this event is completely unknown and is a matter of pure speculation. This occurance was not a conventional explosion but rather an event filling all of space with all of the particles of the embryonic universe rushing away from each other. The Big Bang actually consisted of an explosion of space within itself unlike an explosion of a bomb were fragments are thrown outward. The galaxies were not all clumped together, but rather the Big Bang lay the foundations for the universe.

The origin of the Big Bang theory can be credited to Edwin Hubble. Hubble made the observation that the universe is continuously expanding. He discovered that a galaxys velocity is proportional to its distance. Galaxies that are twice as far from us move twice as fast. Another consequence is that the universe is expanding in every direction. This observation means that it has taken every galaxy the same amount of time to move from a common starting position to its current position. Just as the Big Bang provided for the foundation of the universe, Hubbles observations provided for the foundation of the Big Bang theory.

Since the Big Bang, the universe has been continuously expanding and, thus, there has been more and more distance between clusters of galaxies. This phenomenon of galaxies moving farther away from each other is known as the red shift. As light from distant galaxies approach earth there is an increase of space between earth and the galaxy, which leads to wavelengths being stretched.

In addition to the understanding of the velocity of galaxies emanating from a single point, there is further evidence for the Big Bang. In 1964, two astronomers, Arno Penzias and Robert Wilson, in an attempt to detect microwaves from outer space, inadvertently discovered a noise of extraterrestrial origin. The noise did not seem to emanate from one location but instead, it came from all directions at once. It became obvious that what they heard was radiation from the farthest reaches of the universe which had been left over from the Big Bang. This discovery of the radioactive aftermath of the initial explosion lent much credence to the Big Bang theory.

Even more recently, NASAs COBE satellite was able to detect cosmic microwaves eminating from the outer reaches of the universe. These microwaves were remarkably uniform which illustrated the homogenity of the early stages of the universe. However, the satillite also discovered that as the universe began to cool and was still expanding, small fluctuations began to exist due to temperature differences. These flucuatuations verified prior calculations of the possible cooling and development of the universe just fractions of a second after its creation. These fluctuations in the universe provided a more detailed description of the first moments after the Big Bang. They also helped to tell the story of the formation of galaxies which will be discussed in the next chapter.

The Big Bang theory provides a viable solution to one of the most pressing questions of all time. It is important to understand, however, that the theory itself is constantly being revised. As more observations are made and more research conducted, the Big Bang theory becomes more complete and our knowledge of the origins of the universe more substantial.

THE FIRST ATOMS
Now that an attempt has been made to grapple with the theory of the Big Bang, the next logical question to ask would be what happened afterward? In the minuscule fractions of the first second after creation what was once a complete vacuum began to evolve into what we now know as the universe. In the very beginning there was nothing except for a plasma soup. What is known of these brief moments in time, at the start of our study of cosmology, is largely conjectural. However, science has devised some sketch of what probably happened, based on what is known about the universe today.

Immediately after the Big Bang, as one might imagine, the universe was tremendously hot as a result of particles of both matter and antimatter rushing apart in all directions. As it began to cool, at around 10^-43 seconds after creation, there existed an almost equal yet asymmetrical amount of matter and antimatter. As these two materials are created together, they collide and destroy one another creating pure energy. Fortunately for us, there was an asymmetry in favor of matter. As a direct result of an excess of about one part per billion, the universe was able to mature in a way favorable for matter to persist. As the universe first began to expand, this discrepancy grew larger. The particles which began to dominate were those of matter. They were created and they decayed without the accompaniment of an equal creation or decay of an antiparticle.

As the universe expanded further, and thus cooled, common particles began to form. These particles are called baryons and include photons, neutrinos, electrons and quarks would become the building blocks of matter and life as we know it. During the baryon genesis period there were no recognizable heavy particles such as protons or neutrons because of the still intense heat. At this moment, there was only a quark soup. As the universe began to cool and expand even more, we begin to understand more clearly what exactly happened.

After the universe had cooled to about 3000 billion degrees Kelvin, a radical transition began which has been likened to the phase transition of water turning to ice. Composite particles such as protons and neutrons, called hadrons, became the common state of matter after this transition. Still, no matter more complex could form at these temperatures. Although lighter particles, called leptons, also existed, they were prohibited from reacting with the hadrons to form more complex states of matter. These leptons, which include electrons, neutrinos and photons, would soon be able to join their hadron kin in a union that would define present-day common matter.

After about one to three minutes had passed since the creation of the universe, protons and neutrons began to react with each other to form deuterium, an isotope of hydrogen. Deuterium, or heavy hydrogen, soon collected another neutron to form tritium. Rapidly following this reaction was the addition of another proton which produced a helium nucleus. Scientists believe that there was one helium nucleus for every ten protons within the first three minutes of the universe. After further cooling, these excess protons would be able to capture an electron to create common hydrogen. Consequently, the universe today is observed to contain one helium atom for every ten or eleven atoms of hydrogen.

While it is true that much of this information is speculative, as the universe ages we are able to become increasingly confident in our knowledge of its history. By studying the way in which the universe exists today it is possible to learn a great deal about its past. Much effort has gone into understanding the formation and number of baryons present today. Through finding answers to these modern questions, it is possible to trace their role in the universe back to the Big Bang. Subsequently, by studying the formation of simple atoms in the laboratory we can make some educated guesses as to how they formed originally. Only through further research and discovery will it be possible to completely understand the creation of the universe and its first atomic structures, however, maybe we will never know for sure.

AGE OF THE UNIVERSE
We now have something of a handle on two of the most important quandaries concerning the universe; however, one major question remains. If the universe is indeed finite, how long has it been in existence? Again, science has been able to expand upon what it knows about the universe today and extrapolate a theory as to its age. By applying the common physical equation of distance over velocity equaling time, which again uses Hubbles observations, a fairly accurate approximation can be made.

The two primary measurements needed are the distance of a galaxy moving away from us and that galaxys red shift. An unsuccessful first attempt was made to find these distances through trigonometry. Scientists were able to calculate the diameter of the Earths orbit around the sun which was augmented through the calculation of the Suns motion through our own galaxy. Unfortunately, this calculation could not be used alone to determine the enormous distance between our galaxy and those which would enable us to estimate the age of the universe because of the significant errors involved.

The next step was an understanding of the pulsation of stars. It had been observed that stars of the same luminosity blinked at the same rate, much like a lighthouse could work where all lighthouses with 150,000 watt light bulbs would rotate every thirty seconds and those with 250,000 watt light bulbs would rotate every minute. With this knowledge, scientists assumed that stars in our galaxy that blinked at the same rate as stars in distant galaxies must have the same intensity. Using trigonometry, they were able to calculate the distance to the star in our galaxy. Therefore, the distance of the distant star could be calculated by studying the difference in their intensities much like determining the distance of two cars in the night. Assuming the two cars headights had the same intensity, it would be possible to infer that the car whose headlights appeared dimmer was farther away from the observer than the other car whose headlights would seem brighter. Again, this theory could not be used alone to calculate distance of the most far-away galaxies. After a certain distance it becomes impossible to distinguish individual stars from the galaxies in which they exist. Because of the large red shifts in these galaxies a method had to be devised to find distance using entire galaxy clusters rather than stars alone.

By studying the sizes of galaxy cluster that are near to us, scientists can gain an idea of what the sizes of other clusters might be. Consequently, a prediction can be made about their distance from the Milky Way much in the same way the distance of stars was learned. Though a calculation involving the supposed distance of the far-off cluster and its red shift, a final estimation can be made as to how long the galaxy has been moving away from us. In turn, this number can be used inversely to turn back the clock to a point when the two galaxies were in the same place at the same time, or, the moment of the Big Bang. The equation generally used to show the age of the universe is shown here:

(distance of a particular galaxy) / (that galaxys velocity) = (time)

or

4.6 x 10^26 cm / 1 x 10^9 cm/sec = 4.6 x 10^17 sec

This equation, equaling 4.6 x 10^17 seconds, comes out to be approximately fifteen billion years. This calculation is almost exactly the same for every galaxy that can be studied. However, because of the uncertainties of the measurements produced by these equations, only a rough estimate of the true age of the universe can be fashioned. While finding the age of the universe is a complicated process, the achievement of this knowledge represents a critical step in our understanding.

NOW WHAT?
In summary, we have made a first attempt at explaining the answers that science has revealed about our universe. Our understanding of the Big Bang, the first atoms and the age of the universe is obviously incomplete. As time wears on, more discoveries are made, leading to infinite questions which require yet more answers. Unsatisfied with our base of knowledge research is being conducted around the world at this very moment to further our minimal understanding of the unimaginably complex universe.

Since its conception, the theory of the Big Bang has been constantly challenged. These challenges have led those who believe in the theory to search for more concrete evidence which would prove them correct. From the point at which this chapter leaves off, many have tried to go further and several discoveries have been made that paint a more complete picture of the creation of the universe.

Recently, NASA has made some astounding discoveries which lend themselves to the proof of the Big Bang theory. Most importantly, astronomers using the Astro-2 observatory were able to confirm one of the requirements for the foundation of the universe through the Big Bang. In June, 1995, scientists were able to detect primordial helium, such as deuterium, in the far reaches of the universe. These findings are consistent with an important aspect of the Big Bang theory that a mixture of hydrogen and helium was created at the beginning of the universe.

In addition, the Hubble telescope, named after the father of Big Bang theory, has provided certain clues as to what elements were present following creation. Astronomers using Hubble have found the element boron in extremely ancient stars. They postulate that its presence could be either a remnant of energetic events at the birth of galaxies or it could indicate that boron is even older, dating back to the Big Bang itself. If the latter is true, scientists will be forced once again to modify their theory for the birth of the universe and events immediately afterward because, according to the present theory, such a heavy and complex atom could not have existed.

In this manner we can see that the research will never be truly complete. Our hunger for knowledge will never be satiated. So to answer the question, what now, is an impossibility. The path we take from here will only be determined by our own discoveries and questions. We are engaged in a never-ending cycle of questions and answers where one will inevitably lead to the other.



COBE continues to search the outer reaches of the universe
DEEP THOUGHTS
It is extremely difficult to separate this subject of science from daily existential pondering. Everyone at some point in time has grappled with the question of why we are here? Some have found refuge in the sheer philosophic nature of this question while others have taken a more scientific approach. These particular wanderers have taken the question to a higher level, concentrating not only on human existence but the existence of everything we know as real.

If you sit and try to imagine the whole of the entire universe it would be mind-boggling. However, science has now told us that the universe is, in fact, finite, with a beginning, a middle, and a future. It is easy to get caught up in the large scale of the issue in discussing years by the billions, yet, this time still passes. As we travel through our own lives here on Earth, we also travel through the life of our universe.

In this chapter, we have made some attempts to explain this journey. It is odd that we will never truly know how it began. We can only speculate and give our best guess. Through our own devices we have been able to produce evidence that these guesses are close to the truth. But centuries from now, will the human race compare us to those who once thought of the Earth as the center of the universe?

Answer 8

big bag theory is all non-sense to me.
Its just a man dat concluded such things coz he/they just want SCIENTIFIC explanation for everythin...
wat i can say is just read d bible....

Answer 9

Maybe you hate it because the TV shows pretend that it a theory of "how things started". It is NOT.

The formal name is Lamda-Cold Dark Matter (LCDM). It's a set of equations that explain how the universe changed, from the time we call T = 10^-35 seconds (not T = 0), up to now. It covers about 98% of what astronomers see in the far universe, outside our own local super-clusters of galaxies, using only about 8 parameters.

LCDM does NOT try to explain what happened before T = 10^-35 seconds. That takes either string theory, a so-called "grand unified theory", or theology.

Answer 10

I don't think there are any scientists who think that the universe used to be an atom. The Big Bang theory states that all matter in the universe used to be contained within a single point, and then quickly expanded outwards - the two are very different. When you scrunch a sponge up, it doesn't lose any sponge-mass. It just occupies less space. The same with the universe, except on a bigger scale; everything that exists, everything you see, was once contained within a gravitational singularity, kind of like a black hole.

You say that this "little atom" blew up. While a lot of people assert this, and even believe it to be true, it's not technically accurate. Think of the difference between a balloon expanding and a bomb going off. Matter didn't expand *through* space, spacetime *itself* expanded, along with the matter in it. What was going on before it expanded is unknown, but we have a very good idea of what went on after that point; there aren't really any major holes in the theory, just a few uncertainties.

As for God, that's not for science to wonder about. Science doesn't comment on the supernatural; you have to figure that out for yourself.

You should probably do some research on this yourself rather than vent about your hatred for cosmological theories on Yahoo! Answers. And if you still don't understand, it's because the subject matter is hard to understand, not because it's incorrect.
