It is the idea that the universe will continue to expand forever.
By contrast, the closed theory states that gravity will eventually cause the universe to shrink.
(I think)
In addition to the above. Essentially it is the theory that the universe has no boundary and is not closed in on itself in any way. The shape of the universe in this case must be either "flat" or "curved" to some extent, but not curved enough to form a cylinder, sphere, ellipsoid or torus.
A theory that has been extensively tested and seems to apply everywhere in the universe si sometimes called a Law or a Natural Law.
the oscillating theory of the universe suggests that the creation of this universe followed the death of the last universe. bethany punter wrote this - scientific genius :) hey scientific genius :) (bethany punter)
The Steady State Universe was an enhancement of upon Albert Einstein's Static Universe and was proposed in 1948 by Hermann Bondi, Thomas Gold, and Fred Hoyle. The revised Steady State Theory was based on an extension of something called the Perfect Cosmological Principle, which holds that the universe looks essentially the same from every spot in it and at every time. Or more simply stated, the revised Steady State Theory promotes that new matter and energy are continuously created as the universe expands and the rationalization for an ageless universe.
It is a rather complicated subject. To put it simply, it is an extension of string theory, where higher dimensional "membranes" exist, and the collision of two membranes was possibly the cause of our own Universe. We supposedly live in a three-dimensional "brane". According to string theory there are ten spatial dimensions plus time.
This is called the Geocentric model, from the latin prefix "Geo-" for earth or ground. This was dropped by the scientific community at the beginning of the renaissance for the Heliocentric model, which states that the sun is the center of the universe. However, even this has been abandoned. The general consensus now is that the universe has no definite center or, if it does, we can never find it due to the dimensional 'curvature' it has.
According to Kepler's Universe theory, the universe was born in 4977 BC.
The no boundary universe theory was formulated in 1983.
The steady-state universe theory
Friedmann Universe Theory was created in 1922.
The Big Bang is the theory that was developed to describe the origins of the universe.
"I believe in the oscillating universe theory."
It is similar to the Big Bang theory. The ekpyrotic theory is, a theory that their is a parallel universe (More than one) In our universe.
An open universe is a universe where all of the galaxies and stars and everything in the universe keep expanding with nothing stopping them. This theory says that the galaxies and stars will keep going further and further from the centre of the universe until everything dies off. This is the opposite of the closed universe theory where everything will expand, and then something will cause a turning point and everything will contract until everything there ever was will fit into a space the size of the dot at the end of this sentence. Then, possibly another 'Big Bang' will happen and start everything over again. :)
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.
well this theory was that the sun was a princaple source of motive power in the universe
The Big Bang Theory tells what happen at the begning of the universe. How the Earth comes into the universe
the theory produced by Stephen Hawking and John Hartle in 1983 that the universe has no boundaries
