Big Bang question . .?

The Universe is not in a greater space as space is the Universe, it is the space itself that expands, there are no edge or border to space and no beyond. The best way to think of it is if all three of our dimensions were the two dimensional surface of a balloon and the balloon was inflated, the "radius" is not in our three dimensions of height, width and depth, it's in another higher dimension, some even say it's time. There is no void or nothingness that the Universe expands into, that's just trying to place the Universe in a Universe. By definition, the Universe is all that there is, if there was nothingness or a void, that would be within the Universe. Ever the multiverse and string theory have to qualify the concept of the universe as all that we now think of as the Universe before they can talk about a multi-verse or a "bulk". They actually use a lowercase universe versus the uppercase Universe to make this distinction.

I think I understand what you're asking. Space itself is expanding (Into what? Some higher-dimensional framework. Seriously.) It expands in all directions. There is no "center" to space, and there is no "outside" space...at least, not that we can access. Even if you could travel instantaneously to any point in the Universe, you probably wouldn't find some surface to space, as if the whole enchilada was stuck inside an expanding glass bubble with true nothingness outside..

In fact, space may wrap around on itself in all directions, meaning that there is a finite (but ever-increasing) volume of space...but no edge. Think of a circle and you've got the idea (but with more dimensions); a circle has a finite circumference but no endpoints.

So the region of space that you occupy right now has always been there...at least, since the Big Bang started...but it was once compressed into a much, much, much, much smaller volume.

I hope that helps. Good luck!

In the early start of the big bang the space we know was always there -- only in condense form. When the elements were blown out into the UNIVERSE time was started and space was stretched. Everything that exist in the UNIVERSE today existed then, all in one neat little packet including space.

Short answer: Modern physics shows how the Big Bang (and thus the universe) grew from nothing but a random quantum vacuum fluctuation, creating the energy and matter as it expanded - with the balancing negative energy in the gravitational field. This doesn't make sense in Newtonian physics or our Newtonian experience, but it does in the physics of quantum mechanics and relativity.

Long answer:

It used to be that science couldn't answer the question about the origin of the universe or of the Big Bang, but that didn't mean we should make up an answer and say that it was the cause. Within the last few decades scientists have discovered some good answers.

Quantum mechanics shows that "nothing" does not exist. There are always quantized particle fields with random fluctuations. Quantum mechanics also shows that events can occur with no cause.

There are many well-respected physicists, such as Stephen Hawking, Lawrence Krauss, Sean M. Carroll, Victor Stenger, Michio Kaku, Alan Guth, Alex Vilenkin, Robert A.J. Matthews, and Nobel laureate Frank Wilczek, who have created scientific models where the Big Bang and thus the entire universe could arise from nothing but a random quantum vacuum fluctuation in a particle field -- via natural processes.

In relativity, gravity is negative energy, and matter and photons are positive energy. Because negative and positive energy are equal in absolute total value, our observable universe is balanced to the sum of zero. Our universe could thus have come into existence without violating conservation of mass and energy — with the matter of the universe condensing out of the positive energy as the universe cooled, and gravity created from the negative energy.

I know that this doesn't make sense in our Newtonian experience, but it does in the physics of quantum mechanics and relativity. As Nobel laureate physicist Richard Feynman wrote, "The theory of quantum electrodynamics describes nature as absurd from the point of view of common sense. And it agrees fully with experiment. So I hope you can accept nature as she is — absurd."

See the 4th link for "The Universe: Big Bang to Now in 10 Easy Steps." And, see the 5th link for "Quantum scientists make something out of nothing."

"The total energy of the universe is precisely zero, because gravity can have negative energy. The negative energy of gravity balances out the positive energy of matter. Only such a universe can begin from nothing. The laws of physics allow a universe to begin from nothing. You don't need a deity. Quantum fluctuations can produce a universe."

- Lawrence Krauss, physicist

"Quantum mechanical fluctuations can produce the cosmos. If you would just just twist time and space the right way, you might create an entirely new universe. It's not clear you could get into that universe, but you would create it."

- Seth Shostak, Senior Astronomer at the SETI Institute

Our planet and sun are made from dead exploded suns, the light we see in the night sky are from stars the no longer exist

Both of the above.
