What is the escape velocity of the Big Bang?

Question

If the Big Bang was a black hole and it expanded/inflated what was the original energy that got the universe over its phenomenal gravity?

Answer 1

interesting question !

and i have an interesting answer.

to "escape" the universe, you have to "leave" its dimensions.

this is a direction we cannot "point to" because we exist inside these dimensions. ( much like a 2-D shadow wanting to "jump off" the surface it exists on ! )

this direction is perpendicular to any of our "real" dimensions. in other words, the edge of the universe is always adjacent to us but we cannot access it.

in this model, the escape velocity can be as slow as you want BUT needs to be in that direction we cannot go ( at least with our technology ).

ultimately, there is no escape velocity in the traditional dimensions we exist in. this makes sense since outside the universe there is non-space and non-time and existence is meaningless there.

Answer 2

There was no escape velocity because before 10^-43 seconds after the Big Bang, all the fundamental forces were unified. That is electromagnetism, gravity, weak and strong forces. So you can't explain what happened 10^-43 seconds after the Big Bang because the physics didn't exist.

Therefore, there was no escape velocity. It didn't exist yet. Also, to travel, you'de have to have space. There was no space, so how could something escape. Not only that, but things didn't exist yet, as in elementary particles.

The singularity also wasn't a black hole because black holes are made of matter, and if there was no matter before the Big Bang or even a short time afterwards, there are no black holes.

Answer 3

There are 2 theories and nobody is quite sure if escape velocity has actually been reached. It depends on the amount of matter in the universe.

Currently and in the past, scientists have thought that the universe is expanding and will continue to do so i.e. escape velocity has been reached, but with the discovery of more matter in the universe, current thought is that the gravitational pull will eventually act when the kinetic energy of the matter becomes less than the gravitational force and the universe will contract, perhaps into another big bang.

Interestingly, the Hindu religion believes in this and even has a time period for the whole thing. They believe that it has occurred several times before and is a contiinuing cycle.

Answer 4

Well If you think about it energy is neither loss nor gain. So if we apply that law to the big bang theory...then the origin of the bang had a way of gathering energy. Like a black hole sucks in everything. I believe that there was something that could collect the energy and use it. Kinda like you run to build inertia before you jump.

Answer 5

the electro-weak force eventually grew to such a point that it overcame the strong forces and caused the point singularity to explode. however, since space itself is defined as the boundaries of the resultant explosion, then there is no velocity that one could travel to exceed the expansion of the univers. as far as energy goes...energy can neither be created nor destroyed, so the sum of all the enrgy in the universe is the amount needed to cause the initial explosion.

Answer 6

Its funny that this question is in physics. the law of physics supposedly cannot be broken and the big bang was supposedly spinning; so the planets should all be spinning the same directionbut not all of them are and Uranus is spinning sideways. however if it was somehow set into motion say by an intelligent designer *cough*God*cough* then it all makes sense.
