Big Rip!
Today, most cosmologists believe there is not enough matter in the universe to halt and revert expansion. Robert Caldwell of Dartmouth University has recently suggested a third alternative for the fate of the universe. His Big Rip scenario is based on astronomical observations made in the late 1990s according to which a mysterious force, labelled dark energy, is responsible for the expansion of the universe. Dark energy makes up 73% of the universe. If the rate of acceleration increases, there will be a point in time at which the repulsive force becomes so strong that it overwhelms gravity and the other fundamental forces. According to Caldwell, this will happen in 20 billion years. "The expansion becomes so fast that it literally rips apart all bound objects," Caldwell explains. "It rips apart clusters of galaxies. It rips apart stars. It rips apart planets and solar systems. And it eventually rips apart all matter." Even atoms would be torn apart in the last 10-19 seconds before the end of time. –Whether or not this scenario will become true is to be decided by future research. Until then, the field is open to speculation.

yeah you don't believe in science you base your opinion on which theory is better supported by the research at hand
the steady state theory has been excluded from possible explanations for it lack of ability to explain the expansion of the universe
i think the big bang theory is more likely to be right than the steady state theory
and that is basically what all science is based on
nothing is definite and nothing is where it is nothing is here and nothing is there
the reason that we know something will fall to the earth is because it is most likely to happen then to not happen
the reason that people accept the big bang theory is because it is more likely to be true than most other theories

The observed conditions of our universe overwhelmingly support the Big Bang theory. Those same observed conditions can NOT be accounted for with the Steady State Theory.

The last educated believer in the Steady State Theory was Fred Hoyle.
He died some time ago.

The Steady State Theory says that there is a constant creating of matter and a constant destruction of matter. Now, we all know that science says that you can neither create nor destroy matter. Therefore this theory is out.
I believe that I saw an answer that said that he/she believed in the big bang theory because has not been disprove. HERE'S A CLUE: IT HAS NOT BEEN PROVEN EITHER!!!

I still believe in the Big Bang and the Ying Yang!
Only because its still not disproven, unlike steady state as.

Science is not a democracy, and you don't "believe in" theories. Scientific validity is not determined by a show of hands. Incorrect theories are excluded by the evidence. SST has been excluded for decades.
