The Big Bang theory doesn't make sense?

Question

Basically, the Big Bang theory tells that in the beginning of the universes creation it was extremely dense. Whats puts the bang in the Big Bang theory is that it explodes and expands infinitively outwards, which is what we call inflation. The theory supposedly explains how the universe was created.

What doesn't make sense is that the Big Bang theory is supposedly back by the theory of general relativity. In the theory of general relativity, gravity is explained. Basically its like holding a towel(space) stretched and placing an orange(mass) on the towel. The indent the orange makes on the towel is like a mass' effect on space, which the indent is what makes gravity, gravity. Its why massive objects, such as planets, have gravity.

The theory about black holes is that they are the evolutionary endpoints of stars at least 10 to 15 times as massive as the Sun. If a star that massive or larger undergoes a supernova explosion, it may leave behind a fairly massive burned out stellar remnant. With no outward forces to oppose gravitational forces, the remnant will collapse in on itself. The star eventually collapses to the point of zero volume and infinite density, creating what is known as a " singularity ". As the density increases, the path of light rays emitted from the star are bent and eventually wrapped irrevocably around the star. Any emitted photons are trapped into an orbit by the intense gravitational field; they will never leave it. Because no light escapes after the star reaches this infinite density, it is called a black hole.

It is said that the universe is expanding faster than light can travel, which it is also said that light cannot escape a black hole.

Why didn't the universe collapse on itself immediately after going supernova? The universe was intially far more massive and dense than 15 suns. If it wasn't, then how can an object more dense and massive exist inside of an object less dense and massive?

Knowing this, isn't it possible that the universe went supernova, then immediately ended up collapsing in on itself to the point of deflating infinitively like a black hole? If this were the case, then the universe's deflation would be like an elongating funnel, which the elongation would give the illusion of inflation.

To sum this up, doesn't this negate the Big Bang theory or show that it is only partially true.

Answer 1

so?

Answer 2

The big bang theory is about the origin of the Universe, not the origin of life on Earth. It does NOT say that all the matter and energy was packed into a small space, it says that space expanded, then a short time LATER became filled with energy, some of which turned into matter. The idea that the big bang was directly responsible for the formation of the Earth and has something to do with the appearance of life on Earth is a deliberate falsehood spread by some supposedly Christian (and other) religious leaders who wish to confuse the faithful and prospective members of their cults. The cause of the big bang is not known and it is quite possible that it will never be known for certain. Since time itself may have appeared at the BB, it is possible there was no "before" as we would normally understand it, therefore a cause may never be known. Some uncertainties you just have to face up to. And by the way, the Universe has no obligation to make "sense" to you or anyone else.

Answer 3

First of all, it wasn't an explosion, it was an expansion. Next, the universe didn't go supernova. A supernova is a dying star, not already a singularity. Not much in common here. Finally, the inflationary period that occurred right after the big bang was expanding space faster than the speed of light and obviously with a force that exceeds that of gravity. Gravity is actually the weakest force in the universe, not the strongest.

Answer 4

Calm down! Hold on! Just a minute!
You are getting all caught up in extremely complex stuff unnecessarily. The basic idea is not complicated, you are just piling on more unnecessary stuff that scientists like to think about but that are totally unnecessary to understand the basic idea.

Here is the basic idea.

We know the universe is expanding because we can measure the speed of distant galaxies from the Doppler shift of the light from them. This is the same Doppler shift that police radar uses to measure the speed of your car. All galaxies are moving in space, some one way and some another way. A few nearby ones are coming toward us. Most galaxies a little farther away are moving away from us. Galaxies very far away are ALL moving away from us and the farther away they are the faster they are moving away. Twice as far away and they are moving away twice as fast. Logically, if you think about where those galaxies must have been millions of years ago, is that they must have been closer to us. And if you think far enough back into the past they all must have been right here. So it seems as if the whole universe at one time was all in one place and has been flying out ever since. Naturally people called that the big bang. But it is nothing more than the first thing that you imagine when you measure the speed of all the galaxies flying away. All that other stuff, about relativity and black holes, is just not necessary to understand the basic idea. Black holes really have nothing to do with the big bang anyway. They are just one more interesting theoretical idea related to gravity.

Answer 5

First of all, why don't all stars immediately collapse to form black holes? It's because there is pressure in the interior of the star that holds it up against gravity. More or less the same thing happens in the early universe. The universe at that time was filled with radiation, and the pressure from this radiation wins out against gravity to drive the expansion.

Answer 6

The big bang only explains how the universe started its expansion. I believe the universe we live in is only one of an infinite amount. M- theory explains this a little further. The current theory states that the universe is part of an 11 dimension existence where infinite universe exist in the 11th dimension. They believe the big bang happened when two seperate universes bump into each other starting what we call the big bang. you can find out more by looking on wikipedia under multiverse, M-theory or Many worlds theory.

Answer 7

You're comparing the big bang to a supernova and they are both two different things entirely.

The actual physics of the big bang are still up for some debate.

Answer 8

Just look at the theory as a model and don't worry what others try to convince you about it. There are lots of models of the cosmos and all are just that and nothing more. It doesn,t make any difference who believes in which model.

Answer 9

simply because you made the same mistake i once did, you compared the primeval atom to a star. big mistake, the primeval atom had no mass, because it was not made of matter, it was made entirely of energy. that energy then cooled and formed matter.

and no, the universe is not expanding faster than the speed of light i dont know where you heard that but its wrong.

Answer 10

Scott, that is a HEAVY question...
Try this:
I recommend a book called, "Simply Einstein", by Richard Wolfson. (Published by W.W. Norton & Company, 2003).
It helped me to get my brain wrapped around the whole thing. It was cool.

Answer 11

My understanding of the big bang theory is limited. I admit, but from my interpretation it was similar to a nuclear bomb. The universe is in the mushroom cloud and as the mushroom cloud expands things are in all kinds of random commotion inside. We are still in the expansion where the reaction is constantly growing out, but one day the mushroom cloud will get sucked back in faster with just as much devestation
