The present-day answer is simple, if somewhat frustrating: we don't know!
We don't know WHY the space in our Universe began to expand about 13.7 billion years ago, and we also don't know why this expansion began to speed up about five billion years ago. We only know that both statements are true.
In that way we are like Johannes Kepler, who figured out that planets are going around our Sun in eliptical orbits. He couldn't say WHY this is occuring, he only knew that it IS. A future scientist, Isaac newton, was able to provide the WHY.
If it turns out that one and only one future scientist does for expansion what Newton did for eliptical orbits -- give the WHY -- then s/he will go down in history as another Newton or Einstein. Most such breakthroughs today, however, are accomplished by several people working together, and incrementally on earlier work.

It is not so much that the universe is expanding, but rather the rationalization for its expansion that provides evidence to support the Big Bang Theory. The Big Bang supports interpreted observational evidence of the Cosmic Microwave Background Radiation (CMBR) barrier that there is an evolutionary expansion of the universe which promotes a finite age for the universe.

∙ 11y agoFusion caused by the sun's huge gravitational field causes hydrogen atoms (the most abundant element in the universe, to "fuse" their nuclei into helium. The force released by this reaction holds up the sun's surface against gravity. Fortunately for Earth the forces are, and have been, in balance for billions of years, and will be for several billion more. After that, watch out! (see the life of a star)

How does expanding universe provide evidence for big bang theory?
It is not so much that the universe is expanding, but rather the rationalization for its expansion that provides evidence to support the Big Bang Theory. The Big Bang supports interpreted observational evidence of the Cosmic Microwave Background Radiation (CMBR) barrier that there is an evolutionary expansion of the universe which promotes a finite age for the universe.
What evidence is collected in support of the big bang theory?
expansion of the universe as shown by the Hubble constant3K universal microwave background radiationetc.
The big bang theory of the formation and expansion of the universe is supported by?
Evidence. See related question.
Which theory of the universe did the 1964 discovery of cosmic microwave background radiation support?
I didn't check the year... But the cosmic background radiation is said to support the big bang theory, because it agrees with the radiation that is expected from an expanding Universe.
What is the accepted name for the theory which explains the formation of our universe?
The Big Bang is the theory that was developed to describe the origins of the universe.
What does the big bang theory have to do with the universes expansion?
It is not so much that the universe is expanding, but rather the rationalization for its expansion that provides evidence to support the Big Bang Theory. The Big Bang supports interpreted observational evidence of the Cosmic Microwave Background Radiation (CMBR) barrier that there is an evolutionary expansion of the universe which promotes a finite age for the universe.

How do planetary systems support the big bang?
They do not, per se. The perpetual expansion of the universe does.
What other name was the big bang theory known as?
Some refer to it as the Great Expansion, because the Universe didn't really "bang", it just began a very rapid expansion.
What is the theory of the beginning of the universe called the?
The big bang theory which is a theory of cosmology holding that the expansion of the universe began with a gigantic explosion between 12 and 20 billion years ago
How does Eisenstein's theory of relativity support the Big Bang theory?
The Theory of Relativity was created by Einstein, not by Eisenstein. Comment: The most obvious thing is that Einstein's equations predicted that the Universe was not "static". So a "Big Bang", expanding Universe fits the theory.
Which theory proposes that all the matter in the universe simply exploded outward after it was compressed into a small space under tremendous pressure?
The big bang theory does not state that "the universe began with a gigantic explosion." The theory suggests that our universe originated from an infinitesimally small point called a singularity. Since all of space was all localized within this point, the rapid expansion of the universe isn't an explosion. An explosion occurs within space, but the expansion of space itself isn't an explosion. Quite simply, there isn't anything outside of space for the universe to explode into. Thus the "big bang" wasn't big, nor did it go bang. Around the time of the big bang (about 13.7 billion years ago), the universe was much hotter and expanding very rapidly (somewhat analogous to an explosion but by no means an actual explosion).
Which theory of the universe did the 1964 discovery of cosmic microwave background radiation support?
I didn't check the year... But the cosmic background radiation is said to support the big bang theory, because it agrees with the radiation that is expected from an expanding Universe.
What name do you give to the theory for the origin of the Universe?
The Big Bang Theory is the name given to the theory of cosmic expansion. The idea is of an ever expanding universe. It posits that at some point all matter in the universe was contained within one point.
How does the big bang theory support the conculsion that the universe is expanding?
Cos it is an amazing tv show
