The evidences of big bang theory depends upon the facts -
from the very first second our universe continues to expand , the distant galaxies are moving away from each other and redshift is directly proportional to the distance between the galaxies . It is related such that if the equation of state denoted by w ( Ratio between dark energy pressure and energy density ) is less that -1 then our universe is pulled apart , this type of energy is called the phantom energy ( a form of quintessence ) and also cosmic microwave background radiation serves As the landmark of big bang theory and it is related to big bang by this way -
In beginning of this universe it was much smaller and hotter and filled with opaque fog of hydrogen plasma and when universe expand and cools down and electron and protons together forms the neutral atoms, it's No longer absorb thermal radiation and make the universe transparent
The Big Bang theory is based on observations such as the expansion of the universe, the cosmic microwave background radiation, and the abundance of light elements in the universe. These observations support the idea that the universe began as a hot, dense state and has been expanding and cooling ever since.
Here's more than one:
1) An expanding universe.
2) The Hubble Constant shows a Universe that was almost infinitely dense about 13.7 billion years ago.
3) Cosmic Microwave Background Radiation -- its existence, isotropy, and spectrum.
4) The ratio of hydrogen to helium.
5) Ratios of long-lived isotopes to their decay products show that the former did not start to decay till about 10 billion years ago.
6) No white dwarf star has been found older than about 10 billion years.
7) Quasars are found far from us, but not close.
All of the above are easily explained through our present understanding of Big Bang Cosmology, but impossible to explain with any other hypothesis.
Edwin Hubble, using the Hubble telescope, is credited with the discovery that the distances to far away galaxies were generally proportional to their redshifts (as in the doppler effect); an idea which was originally predicted by Lemaître in 1927. Hubble's observation was taken to indicate that all very distant galaxies and clusters have an apparent velocity directly away from our vantage point: the farther away, the higher the apparent velocity.
Other supportive evidence for the big bang Theory - Cosmic Microwave Background Radiation has been discovered and it is suggested that this has been left over from the Big Bang and galactic clusters are still moving away from each other at an ever increasing acceleration.

What was Galileo's contribution to the Big Bang Theory?
Galileo did not contribute to the Big Bang Theory directly as his work focused on astronomy, not cosmology. The Big Bang Theory was developed in the 20th century based on evidence from observations of the universe's expansion. Galileo's contributions to astronomy include improving the telescope and making important astronomical observations, such as the phases of Venus and the moons of Jupiter.
When do scientists think the Big Bang theory happened?
Scientists estimate that the Big Bang occurred approximately 13.8 billion years ago based on observations of the cosmic microwave background radiation. This radiation is considered the afterglow of the Big Bang and provides valuable information about the early universe.
What law does the big bang theory break?
The Big Bang Theory does not break any specific laws of physics. It is a scientific model that describes the origin and evolution of the universe based on observations and theoretical calculations. However, there are still many questions and mysteries surrounding the Big Bang Theory that scientists are actively working to understand.
Who proposed big bang and universe is expanding explain?
The history of the Big Bang theory began with the Big Bang's development from observations and theoretical considerations. Much of the theoretical work in cosmology now involves extensions and refinements to the basic Big Bang model.
How is the big bang theory is an example od scienctific theory?
Hello i am minakshi answer is that the big bang theory is an example of old scientific theory as big bang theory explains that there was an explosion but the isotropy and the homogenity of the universe is not explained by big bang theory to explain his we connect inflatation theory with big bang theory to explain it so the big bang theory is also an example of old scientific theory.
Why is the big bang theory importanat?
The Big Bang Theory is important as it is the framework for understanding the Universe. The framework holds observations together and explains new observations.
What was Galileo's contribution to the Big Bang Theory?

The Big Bang Theory was developed in the 20th century based on evidence from observations of the universe's expansion.

Was the big bang theory based on religion?
No.

Why is the big bang a theory and not a law?
The Big Bang Theory is a scientific explanation based on observations and evidence, but it is still subject to refinement and further testing. Scientific laws describe observed phenomena but do not explain why they occur, while theories offer explanations based on available evidence. The Big Bang Theory continues to be tested and refined as new discoveries are made in the field of cosmology.
Why was the big bang theory?
The Big Bang theory was set up to explain observations - for example, the redshift of distant galaxies, which is usually interpreted to mean that the galaxies move away from us.

What show is funnier Big bang theory or The office?
Based on ratings, the public seems to think that The Big Bang Theory show is funnier than The Office.
Is your formation of space based upon big bang theory?
As it should be.

The most recent theory that upholds the big bang theory but suggests a sudden expansion after the bang is called the?
Inflation theory. This theory suggests that in the first moments after the Big Bang, the universe underwent a rapid and exponential expansion, causing it to grow exponentially in size. This concept helps explain certain observations of the universe, such as its large-scale structure and uniformity.
