The facts that provide 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, are overwhelmingly persuasive.
1) The distance between us and all distant galaxies is increasing, and the rate at which that distance is increasing is directly proportional to the distance to those distant galaxies.
2) The existence, spectrum, and isotropy of the cosmic microwave background radiation.
3) The ratio of hydrogen to helium in all parts of our Universe.
4) Quasars are seen far from us, but not close to us.
5) The ratio of long-lived isotopes to their decay products.
6) The absence of white dwarf stars older than about ten billion years.
These facts make Big Bang Cosmology as solid an idea as a heliocentric solar system.
What else can I help you with?
Is a scientific theory or law an attempt to explain a pattern observed in the natural world?
The theory is based on replicable evidence. This evidence turns a theory into a fact.
What are myths about the Big Bang THEORY?
The Big Bang Theory is a widly accepted theory in the scientific world because of the fact that it has less loopholes than others made to oppose it.I believe 1-2 loopholes are contained in The Big Bang Theory.
Why is the big bang theory a model and not absolute fact?
All scientific theories are basically just consensuses of postulates to guide scientific research in a search for evidentiary proof. Consequently no theory is absolute fact. In the case of the Big Bang theory we also have the problem that we are trying to figure out what happened billions of years in the past, long before any human beings were around to observe those events directly. We have lots of astronomical observations which are relevant to this theory, but it is possible to imagine more than one way to interpret those observations. That said, you should also know that the evidence for the Big Bang theory is quite strong, and no one working in the field of cosmology has any serious doubt about it. It is very well supported. But it is not absolute fact. Nothing in science is taken as being absolute. For absolute truth, you must turn to religion.
Is the steady state a theory o a fact?
The Steady State theory is now an obsolete theory. It was an interesting alternative to the normal Big Bang theory, but it doesn't agree with observations.The Steady State theory is now an obsolete theory.

Does a theory have to be supported by evidence?
Yes, a theory should be supported by evidence in order to be considered valid and credible. Evidence helps to substantiate the claims and predictions made by a theory, allowing for testing, verification, and refinement of the theory as needed.
How do they know the big bang theory happend?
They didn't; the big bang theory is just an idea or a theory, not a fact. The empirical evidence that our Universe was, 13.7 billion years ago, much more dense that it is now, is overwhelming. No other explanation even begins to explain what we observe in our Universe. Saying the Big Bang is a "just an idea or theory" is like saying gravity is "just an idea or a theory, not a fact."
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.
What does the big bang theory say about the movement of galaxies?
The Big bang theory states that the galaxies are in fact moving away from each other
What form of evidence is used to to support the big bang theory?
The redshift of distant galaxies, which is normally attributed to the Doppler effect.=========================Comment #1:It's important to include in the answer the fact that the question speaks ofhow science is NOT done. Evidence is not used to support theory. Theoryis the attempt to explain existing evidence. THAT's how science works.

What fact do scientists believe provides evidence for the Big Bang Theory?
The discovery of cosmic microwave background radiation is a key piece of evidence for the Big Bang Theory. This radiation is a faint glow found throughout the universe, believed to be leftover from the intense heat of the Big Bang. Its characteristics match what would be expected if the universe started as a hot, dense state and expanded over time.
What is antonyms of theory?
Antonyms of theory include fact, reality, evidence, and truth.
How can science be facts if they are theories to begin with?
A theory becomes a fact when that theory is supported by experimental evidence.
How do you make a hypotheses?
A hypothesis is a statement of theory. Something that is unproven. You gather evidence to support that theory. Gather enough evidence to support and a theory becomes accepted as fact.
