Cyclic Universe Theory
by: Zoe Zimmerman and Anna Graff
What is cyclic universe theory?
Question
cyclic universe theory was first introduced over 20 years ago. It proposes that the universe is reborn in an endless cycle of expanding and cooling, starting with a "big bang*" and ending in a "big crunch**". This theory promotes the law of conservation of matter and is one of many theories about the universe today.
*Big bang
*the big bang
the big bang theory is a popular theory that says the universe was started with a huge explosion.
**the Big crunch
**the big crunch
the big crunch is a lesser known popular theory that the universe will expand enough for gravity to make the universe collapse in on itself.
Origin of the Theory
Origin
The Cyclic Universe Theory was proposed by Peter Steinhardt, a proffesor at Princeton University, as well as Neil Turok at Cambridge University. However, scientists have been debating it for a while. In the 1920s, Albert Einstein believed that this could be true, but the theory was debunked in 1934 by Richard Tolman. It remained unchecked until reintroduced by Steinhardt, who revisited and perfected it in 2001.
what does this theory solve?
How and Why
Steinhardt, the founder of the current thory, says that our universal model has a signficant number of flaws.
for one, there are so many ways that the universe couldv'e turned out that the current theory can't incorporate. With the cyclic universe theory, there are infinite opportunities for infinite universal outcomes.
another flaw with the theory is that it doesn't include what's before the big bang, which doesn't align with the law of Conservation of Matter. cyclic universe theory makes a clean loop that goes throughout.
Fun facts
Fun Facts
- The Cyclic Universe Theory involves a combination of the Big Bang Model, the Inflationary Theory, and Robert Steinhardt's original ideas.
conclusion
in conclusion, While it is not very popular, the cyclic universe thory is possible and not only explains but possibly improves the big bang theory. Anything's possible. And remember, stay curious kids!
