The same type of evidence that supports the idea that our Earth goes around our Sun -- if our solar system is geocentric, we'd observe one thing; if heliocentric, we'd observe something different. Since what we DO observe is what we WOULD observe if our Earth goes around our Sun, then we conclude it DOES -- even if 25% of Americans do not believe that to be the case.
The evidence that the space within our Universe was almost infinitely dense about 13.7 billion years ago, and has been expanding at a (pretty much) steady rate ever since, is overwhelmingly persuasive.
Amongst the evidence in favor:
1) The distance between us and all distant galaxies is increasing, and the rate at which the distance is increasing is directly proportional to the distance between us and these galaxies.
2) There exists an isotropic (to one part in 10,000) and continuous radiation, with a spectrum of a blackbody at 2.7K. This is exactly as predicted by BBC, and allows to see light from our early Universe -- less than 400,000 years after the Big Bang.
3) The ratio of hydrogen to helium in all parts of our Universe are exactly as predicted by BBC.
4) The ratio of long-lived isotopes to their decay products shows decays began about 10 billion years ago.
5) Quasars are seen far from us, but not close to us.
6) The absence of white dwarf stars older than about ten billion years.

How many people believe in the big bang theory?
It depends, because some might say 'scientists'. But not all scientists believe in this theory. Also, there are those who believe in a similar idea to the Big Bang, but it is not refered to as 'The Big Band Theory.'
What scientist believe provides evidence of the big bang theory?
Scientists do not sit in the coffeeshop and dream up a theory and thengo looking for evidence to support it. Scientists make observations andmeasurements of what IS ... the "evidence" you might say ... and then tryto put together a theory to explain what they see.The "Big Bang" theory is the best explanation so far for the observation that allgalaxies in every direction are receding from us at speeds that are proportionalto their distance from us, and for the observation that all of space is filled withan almost uniform level of electromagnetic radiation with a distribution of wavelengthsthat is characteristic of a blackbody at the temperature of 2.7 K, and for theobservation that on the largest scale, the universe consists of roughly 75%hydrogen and 24% helium.
Why did other scientists question the theory of plate tectonics?
At the time when this theory was a-brewing, it was difficult to provide conclusive data and evidence.
Although Dalton's atomic theory was rejected at first he used his theory to do what that soon resulted in his theory being accepted by scientists?
Instead of just stating his own personal opinions John Dalton cited evidence to support his atomic theory. The giving of evidence - which could be proved or disproved by others - was what soon resulted in his theory being accepted by scientists.
Why was wegeners theory so different?
Wegener's theory of continental drift is supported by a vast quantity of evidence, which is why scientists have accepted it.
What fact do all scientists believe provides evidence for the Big Bang theory Apex?
The cosmic background radiation - in the microwave part of the electromagnetic spectrum.
Did 'man' start from apes?
Some people believe in that theory, but some people believe in Adam and Eve. Scientists claim that they have found evidence that we started from apes.
Which of the following provides evidence that led many scientists to accept Darwin's theory of natural selection instead of earlier theories?
Similarities among embryos.
What is the theory that all the scientists provided evidence for the cell theory?
For their own benefits.
Why did many scientists not accept the early theiories of continental drifts?
Alfred Wegener did not have the "HOW" factor- because of no evidence on the process, they could not believe his theory.
Why did most scientists reject Wegner theory for nearly a half century?
They rejected Wenger's theory for half a century because he didn't have the evidence to prove his theory No, He did have evidence to prove his theory, they just did not believe him- TheSystem because of their lack of knowledge of the Earth He actually had evidence, but it was actually because the hypothesis interferred with their own hypothesis about how mountains form.
Why do scientists believe that the universe began with an explosion?
Because the theory fits all the evidence so far. There are still difficulties with it and more questions need to be answered but it seems to be the best theory at present.
Do you think that scientists still believe the cell theory today?
Of course they do. Scientists believe anything that they think is true.
If new evidence does not support a scientific theory scientists will most likely?
modify the theory or discard it altogether.

Who were the two scientists that brought forth supporting evidence to wegener's theory?
me and your mom
When would scientists need to change a theory?
Scientists had made observations that did not fit exactly with Dalton's theory. Scientists changed the atomic theory to include this new knowledge. While the modern atomic theory is based on Dalton's theory, it is also very different.
