Big Bang theory
- Most people think the earth was created from the big bag
- scientists believe this happened 13.7 billion years ago
- the big bang sent the particles of the universe in all directions, this was the cause of all of the planets and galaxies being created.
- the big bang model suggests that 10 million years ago all the matter in the universe was contained in a hot, dense ball of radiation and subatomic particles.
The Steady State Theory
- the steady state theory says that the universe was always there and is expanding further away and every thing is moving further away from each other.
- the steady state theory has been proven incorrect.
- Fred Hoyle is one of the first people to have thought of the steady state theory.
- the steady state theory was thought of in 1949 and was used as a different alternative of the big bang theory.
Arguments against both theories
Against big bang
Against steady state
Most Believed/ proven theory
the big band theory is the most believed theory that scientist have thought of. this is because they have proven this theory is true many times. they have seen more galaxies being created, stars and planets moving farther away from the earth and the big bang theory is the only theory that has been proven for the earth's creation
which theory do I believe is true?
I believe the big bang is the most likely thing that would have happened and because this theory has evidence that proves that this is true. unlike the steady state theory, on numerous occasions this has been proven wrong because the universe is expanding creating new galaxies, stars and planets.
Against big bang
- that there is no proof that the big bang happened
- the universe has always been here and will always stay the same
- there was no way to find out if this really happened
Against steady state
- scientists have discovered that the universe is expanding and creating new galaxies
- they have researched over many years for proof of the big bang
