Not at the present time, just like scientists haven't yet figured out why there is lightning in our skies. The idea that our Universe has been expanding at a (more or less) steady rate for the last 13.7 billion years, is just as proven as the idea that our Earth goes around our Sun. However, as Alan Guth said so well: "The Big Bang theory says nothing about what banged, why it banged, or what happened before it banged."
I believe most scientists would agree that this is not currently known. Some, however, would say that there was no "before" - that time itself started with the Big Bang.
Scientists don't "think" it was gravity, scientists know that it was gravity.
We know how big it is now, we know how old it is, and we know the rate of expansion. Its like rewinding a movie that you started in the middle. We just rewind the known universe as it is now. We dont know how big it was before the big bang but we know how big it was at the initial kaboom.
yes because that's what started the big bang
The big bang began the expansion of spacetime with great rapidity. The Universe began with the Big Bang. In other words both space and time began at the big bang. The big bang started the Universe from the point t=0.
No, but there are many theories. The big bang, God, and many more.
Many scientists believe that the big bang started life. The big bang was a big explosion and the galaxies began.

The Big Bang Theory
The Big Bang theory isn't a mystery: the scientists working on it know exactly what they mean by what they say.
the scientists believe the big bang took place is northeast
The Big Bang Theory is widely considered by scientists and theologians as the way in which the universe started. Even the Pope accepts it.

The beginning of the universe. the Big bang we "know" when it started (about 13.7 billion years ago see the big bang) but we have NO idea why it started. That's why people invent gods.
In our Universe, ultimately everything started with the Big Bang. We don't know what came before that... or if there even was a "before".
