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?
The Big Bang theory is accepted by the majority of the scientific community and is supported by evidence like the cosmic microwave background radiation. It is estimated that a significant majority of scientists and researchers in relevant fields accept the theory as the most plausible explanation for the origins of the universe. It is difficult to provide an exact number of people who believe in the Big Bang theory outside of the scientific community.
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.
Astronomers use various tools to gather evidence in support of the Big Bang Theory What are two tools used?
Two tools astronomers use to gather evidence in support of the Big Bang Theory are telescopes and cosmic microwave background radiation observations. Telescopes allow astronomers to observe the expansion of the universe and the cosmic microwave background radiation provides a snapshot of the universe shortly after the Big Bang.
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?
Dalton used his atomic theory to explain and predict the behavior of gases, particularly in his work on combining volumes of gases in chemical reactions. This provided experimental evidence that supported the atomic theory and ultimately led to its acceptance by scientists.
What do the opponents of the global warming theory believe?
Opponents of the global warming theory may believe that the Earth's climate changes are natural and not primarily influenced by human activities. They may also argue that the scientific evidence supporting global warming is inconclusive or exaggerated, and that policies to address climate change could have negative economic impacts.
What fact do all scientists believe provides evidence for the Big Bang theory Apex?
The fact that the universe is expanding is a key piece of evidence for the Big Bang theory. Observable redshift of distant galaxies, cosmic microwave background radiation, and the abundance of light elements like helium and hydrogen all support the idea that the universe began in a hot, dense state and has been expanding ever since.
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?
The discovery of genetics and the mechanism of inheritance through Gregor Mendel's work provided evidence supporting Darwin's theory of natural selection. This, along with the fossil record showcasing transitional forms and the observation of adaptation in response to environmental pressures, led many scientists to accept Darwin's theory over earlier ideas like Lamarckism.
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.
What are 2 of the 3 reasons that scientists believe the plates are moving?
Scientists believe that the plates are moving due to the evidence of seafloor spreading at mid-ocean ridges and the distribution of earthquakes along plate boundaries. Additionally, the study of paleomagnetism provides further support for the theory of plate tectonics.
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?
Scientists believe in the Big Bang theory because it is supported by evidence such as the cosmic microwave background radiation and the observed expansion of the universe. These observations suggest that the universe was once in a hot, dense state and has been expanding since its beginning.
What continent scientists believe early modern humans came from?
Scientists believe early modern humans originated in Africa. This theory is supported by fossil and genetic evidence that suggests humans evolved in Africa before migrating to other continents.
Do you think that scientists still believe the cell theory today?
Yes, scientists still believe in the cell theory today because it is a well-established and widely accepted principle in biology. The cell theory states that all living organisms are composed of cells, and all cells come from pre-existing cells through cell division.
Who were the two scientists that brought forth supporting evidence to wegener's theory?
me and your mom
