Big bang theory?

Question

How is it that nothing came from nothing? Is that scientifically possible? And here comes the criticism...

I think this is the right section considering it directly contradicts most major religions.

ok, about the universe is expanding thing. I asked about how it started. The universe apparently started with a bang. What started the big bang? And if you say that there were still things existing before that, what created it? If the universe never started, and time is infinite, why is that the world is not perfect yet? isn't that what evolution is? life constantly striving towards perfection? if there was an infinite amount of time, the world would either be gone, or be absolutely perfect, it would not still be in the process of being perfected, still being discovered if time was eternal.

sorry typo. Something come from nothing.

Answer 1

Wrong section.... Nothing leads to nothing. Nothing else. And to me, it isn't possible for something to come from nothing. There had to be something in the beginning. What that something is... is the real question.

Answer 2

How can something come from nothing? It can't. That's why I don't believe in a deity that created the universe from nothing. I, as an atheist, believe that the universe has always existed and will always exist.

An important law in physics states that matter, nor energy can be created, nor destroyed. It converts constantly. They say some parts of your body were once part of a star.

If you say God created the universe, I ask you:
- How did he do it?
- Who created God?
If you say God was not created, I say the universe was not.

What happened before the Big Bang does nobody know. Some believe it fell in a gravity hole, but that is of no importance here.

>>The universe apparently started with a bang.

There is no proof the universe started with a bang, because there is no evidence that the big bang was the first event in the universe.

>>And if you say that there were still things existing before that, what created it?

The universe, in my opinion, was not created. It transforms itself constantly, as it becomes more complex. Every action is known to cause at least one reaction. Hence, it will eternally continue. The universe will never be destroyed, even if only heat remains. The big bang is tought to decrease in density.

>>If the universe never started, and time is infinite, why is that the world is not perfect yet?
isn't that what evolution is? life constantly striving towards perfection?

1. Perfection is relative. What is perfect in your opinion, might not be perfect in mine.
2. Perfection, as a state of flawlessness, to someone, can never be fully achieved. We constantly need to adapt. Soon the earth is history, hence we must adapt ourselves to find a new location to live.

Answer 3

"Everything" came from the singularity, a dense point of matter similar to the center of a black hole. Matter can be packed together through increasing gravitational pull which in turn increases due to the increasing density. It is believed that there is a "breaking point" when the "everything" becomes unstable and explodes (this is one theory because it is not known what happened immediately prior to the Big Bang). What existed before that is unknown or why the singularity existed is unknown. This actually does not contradict the major religions. Creationism does not describe details about how life or the universe came about. It is said that the universe was created in six days, the problem is how would a being with eternal life determine time for himself? One "day" could be a week or one million years to us. The Big Bang simply describes how we believe the universe started, it does not preclude that a superior being did not set it in motion. Check out Intelligent Design if you want to know more.

Evolution is not the striving for perfection, it is all about adaptation to surrounding conditions. Weather patterns, drought, heat, cold, all of these things are not subject to evolution, living creatures are so they have a chance of surviving an ever changing Earth.

Answer 4

It is occuring right now (universe is expanding into a larger celestial object) so i do think it is scientifically possible. The expanding of the universe shows that the universe is ever-expanding. I am not sure whether it started as small as a point on a needle is true (sounds too farfetched to me) but it makes sense that it did start small (maybe not as small as indicated in the theory) and is now expanding. Everything in the universe came from that compact ball of energy, so the universe did come out of something (the expansion of that energy by the four types of forces).

Answer 5

That's a great question.

My biggest problem with the big bang theory is creation of mater and energy from nothing.

Big explosions don't change the laws of Physics. The fundamental working of the universe never change, and it is obvious that mater and energy don't get create or destroyed, although they can be converted from one to the other.

Several people state that the big bang theory doesn't state that everything came from nothing. However, there are many different versions of the theory, and some of them I've heard state that "everything came from nothing" See references. The Big Bang theory's purpose is to explain the beginning (or origon) of the universe. To any rational person that means that the Universe didn't exist, and what is the universe made of? Mater and energy and the laws that govern them. I don't believe that the universe has a beginning.

S.H. stated that gravity is negative energy. This is not correct. I have heard and believe that gravity is negative entropy.

Answer 6

I'm afraid no answer here is going to be very satisfactory. The truth is that modern theoretical physics does have a good theory known as Cosmic Inflation that addresses these questions, but you need to have an advanced education in Physics to really be able to understand that theory. If you are serious about trying to understand, I suggest you start with the wikipedia link below.

I think you misrepresent evolution. The goal of evolution is not perfection. Evolution does say that species will adapt to become more successful in their environment, but "perfection" is relative to the environment. A great white shark is pretty successful in its environment, which is why that species haven't evolved much in a long time. Homo Sapiens is even more successful, and probably won't evolve genetically unless there is something that radically changes our physical enviroment -- like global warming.

Answer 7

Not sure what your question is, do you mean you don’t see how everything came from nothing? You might read these two sites:

http://www.umich.edu/~gs265/bigbang.htm

This next site is a new spin on it.

http://www.theaustralian.news.com.au/story/0,20867,20192903-30417,00.html

EDIT:
Good you clarified your question
Second site is a theory that attempts to answer what started it but we are not to that level of science yet. Evolution is the struggle to survive not become perfect.

Belief part: What is perfection anyway, no struggle, no pain, no problems? That is not perfection it is death, stagnation. God is infinite, without beginning or end all else is finite. Perfection seems to be your idea of the purpose of life, God was perfect and complete before this. The illusion of imperfection was needed to have something to compare the perfection to. The goal is not perfection but to experience the imperfection and to express our true selves in relation to it.

Answer 8

It is possible that something came from nothing. And that is exactly the direction that Quantum mechanics is moving in. When energy passes over a void and causes a disruption something comes from nothing. Perhaps the energy was God. The hole in the Universe by K.C.Cole is very good in summarizing and explaining how scientists believe that something did indeed come from nothing.

Answer 9

Wait... nothing came from nothing? Do you mean something came from nothing? Before the Big Bang (according to the theory) there was singularity, which exploded very rapidly into a universe.

Answer 10

You see, ALL matter is is Energy...

And ALL matter comes with gravitational Energy....

Gravitational energy is Negative energy...

The sum of the positive Matter energy, and the negative gravitational energy is zero... Therefore, there hasn't been anything that has come from nothing.

Everything is NEUTRAL... If the positive energy outweighed the negative energy, THEN there would be something from nothing....

Furthermore, matter comes from light... This has been confirmed in labs with high power gamma rays.

When light is released with enough energy, it can degrade into photons, which then split into antimatter and matter, which usually annihilate each other, accept that small fragments of matter are always left over. It was these fragments that formed all the matter in the universe today...

Answer 11

Big bang theory begins with a primordial atom.
An object about the size of a softball.
It was pure energy that just went unstable.

For Christians (let there be light)
