The universe have been expanding since the big bang. After the first 200 seconds after the creation of the universe, the universe was the size of galaxy. Now how much the universe size is nobody can measure It is also said that a lot of matter and antimatter have been destroyed since then.
In the first few moments of the universes creation, particles called quarks were formed. They soon fused to create the first atoms called hydrogen and helium. Larger atoms such as beryllium, oxygen and carbon were formed by the nuclear reactions inside stars. Even bigger atoms were formed due to the shock waves inside the stars such as tungsten or osmium.
But all this took a lot of time to happen.

What are the theory's about the universe?
Well I do now one theory about the universe. It's the big bang theory. The big bang theory is a theory about how the universe was created.Scientist think that a big explosion created the universe.Scientist found lots of evidence that the big bang theory was true.

Exactly the same, there was no big bang!! That theory has been proven wrong.
What are some questions about the Big Bang theory and its implications for the origin of the universe?
Some questions about the Big Bang theory and its implications for the origin of the universe include: What caused the Big Bang? How did the universe evolve after the Big Bang? What evidence supports the Big Bang theory? What are the implications of the Big Bang for our understanding of the universe's beginning and future?
What is a result of the big bang?
The big bang began the expansion of spacetime with great rapidity. The Universe began with the Big Bang. In other words both space and time began at the big bang. The big bang started the Universe from the point t=0.
Is there any chance to occur the big bang without universe?
Our concept of the "big bang" has no explanation about how or why, but our hypothesis is that there was NOTHING before the Big Bang created the universe.
What theory do scientists accept as an explanation for the origin of the universe?
Still now the most acceptable theory on the origin of universe has been the big bang theory. you can get more info on big bang theory from wikipedia.
Event that marks the beginning of the universe?
The event that marks the beginning of the universe is the Big Bang. This was a cosmic event that occurred about 13.8 billion years ago, creating the universe as we know it today. The Big Bang theory is widely accepted by scientists as the most plausible explanation for the origin of the universe.
What was made during the big bang?
Within ten seconds of the start of the Big Bang, all hadrons and leptons that now reside in our Universe came into existence.
Where does energy came from originally?
All the energy that is now in the Universe was there since the time the Universe started - that is, since the Big Bang.
How the temperature of the Universe dropped after the Big Bang?
The big bang was the BEGINNING of the universe so there was no temperature before it :P
What does the Big Bang theory tell us about the universe?
The Big Bang Theory tells what happen at the begning of the universe. How the Earth comes into the universe
What theory many scientists accept as an explanation of the origin of the universe?
