Which theory about the universes size best matches the experimental evidence found by astronomers and physicists?
The theory of an expanding universe, known as the Big Bang theory, best matches the experimental evidence found by astronomers and physicists. Evidence such as the cosmic microwave background radiation and the redshift of distant galaxies support the idea that the universe began as a singularity and has been expanding ever since.
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.
How long has hydrogen been around?
Henry Cavendish, a young English chemist, discovered that hydrogen is a separate substance in 1766. It was also discovered that hydrogen is found naturally in the atmosphere, and when hydrogen is burned it produces water vapor
How many earthquakes has there been since the big bang?
We do not currently know and in fact we may never know. Due to the nature of the big bang, and the fact that all space, matter and energy are a direct result of it, there is no way to accurately detect anything outside of its scope. Everything we know about the universe comes from observing and analyzing the universe around us. Since the universe we know did not exist before the big bang there is nothing we can learn about the "before time" from observing the universe we live in. There may have been a universe before that which went into a "big crunch" which led to the big bang of our universe. It is natural to assume that if that were the case then that previous universe must have also had its origins in a big bang as well, and perhaps its all part of a huge cycle. In fact, since the big bang is the origin of everything in our universe, including space itself, it may also be the origin of time itself, and so there may not have been a "before" the big bang. But more to the point, in order for another big bang to occur, the universe would have to be compressed in a "big crunch" into a singularity before that could happen. There are some theories which point this direction, and there are some which do not.
Who made hydrogen?
Nobody made hydrogen---unless you believe in God and then he made hydrogen. Hydrogen was a byproduct of the cooling off of matter after the Big Bang. The first hydrogen ions are believed to have formed around a microsecond after the big bang. Actual hydrogen atoms (with electrons associated with the protons) did not occur until hundreds of thousands of years later.
What is happening to the universe since the big bang?
Since the Big Bang, the universe has been expanding. Galaxies are moving away from each other as space itself expands. This expansion is happening at an accelerating rate, driven by dark energy.
What was the size of the universe at the time of the big bang?
The size of the universe at the time of the Big Bang is estimated to have been extremely small, even smaller than a proton. The universe has been expanding ever since the Big Bang occurred approximately 13.8 billion years ago.
What did the big bang scatter through space?
The Universe! Initially everything was crammed into an infinitesimally small point but since the Big Bang all the matter and energy that make up our Universe has been expanding outwards.
What do scientists call the event that started the universe?
Scientists refer to the event that started the universe as the Big Bang. This is a cosmological model that suggests the universe began as a very hot, dense state and has been expanding and cooling ever since.
How did the size of the universe change?
In the immediate aftermath of the "Big Bang" there was rapid inflation of the universe. That slowed and the universe is now believed to be still, slowly, expanding.
How is nuclear energy created or formed?
Uranium formed in supernova explosions. Hydrogen has been in the universe since milliseconds after the big bang.
What sentence can you make using the word Big bang theory?
The Big Bang Theory is widely considered by scientists and theologians as the way in which the universe started. Even the Pope accepts it.
A theory that the universe began in a giant explosion?
This theory is known as the Big Bang theory, which suggests that the universe started from a very high-energy and dense state and has been expanding ever since. The Big Bang is supported by various lines of evidence, such as the cosmic microwave background radiation and the abundance of light elements in the universe.
What theory do many scientists accept as an explanation for the origin of the universe?
Many scientists accept the Big Bang theory as the explanation for the origin of the universe. This theory proposes that the universe began as a singularity approximately 13.8 billion years ago, and has been expanding ever since. The evidence for the Big Bang includes the cosmic microwave background radiation and the observed redshift of distant galaxies.
Was the big bang a asteroid?
No, the Big Bang was not an asteroid. The Big Bang theory is the scientific explanation for the origin of the universe, proposing that it began as a singularity and has been expanding ever since. An asteroid is a rocky object in space that orbits the Sun, and is not related to the concept of the Big Bang.
What is the most recognized model of how the universe begun is known as?
The most recognized model of how the universe began is the Big Bang theory. This theory proposes that the universe expanded from a very high-density and high-temperature state approximately 13.8 billion years ago, and has been expanding ever since.
How long has energy been around?
Energy has existed since the beginning of the universe, approximately 13.8 billion years ago, when the Big Bang occurred. Energy cannot be created or destroyed but only transformed from one form to another. Throughout the history of the universe, energy has constantly been in flux, driving all processes and phenomena.
