How did the Big Bang create space?

The Big Bang is not an explosion of matter moving outward to fill an empty universe. Instead, space itself expands with time everywhere and increases the physical distances between comoving points. In other words, the Big Bang is not an explosion in space, but rather an expansion of space.

What created the matter for the Big Bang?

Origins. In the first moments after the Big Bang, the universe was extremely hot and dense. As the universe cooled, conditions became just right to give rise to the building blocks of matter – the quarks and electrons of which we are all made.

What was the universe made of right after the Big Bang?

After the Big Bang, the universe was like a hot soup of particles (i.e. protons, neutrons, and electrons). When the universe started cooling, the protons and neutrons began combining into ionized atoms of hydrogen (and eventually some helium).

Did the Big Bang theory create space?

While an explosion of a man-made bomb expands through air, the Big Bang did not expand through anything. That’s because there was no space to expand through at the beginning of time. Rather, physicists believe the Big Bang created and stretched space itself, expanding the universe.

What is the Big Bang theory?

The Short Answer: The big bang is how astronomers explain the way the universe began. It is the idea that the universe began as just a single point, then expanded and stretched to grow as large as it is right now—and it is still stretching!

How did the universe expand before the Big Bang?

Still other models revolve around the formation of the pre-Big Bang singularity itself. If you think of black holes as cosmic trash compactors, they stand as prime candidates for all that primordial compression, so our expanding universe could theoretically be the white hole output from a black hole in another universe.

What is the Big Bounce theory of the universe?

They believe that instead of a Big Bang, the universe expands and contracts in a cycle, bouncing back each time that it shrinks to a certain size. In the Big Bounce theory, each cycle would begin with a small, smooth universe that wouldn’t be as tiny as the singularity.

Was the universe hibernating before Big Bang?

The universe was hibernating until something set it in motion. This idea says that the pre-Big Bang universe was a small, flat, high-pressure space that was “metastable,” or stable until it found an even more stable state — the way a house of cards might sit perfectly solid forever until a breeze came through.
