- expansion
- The Big Bang
- an infinitely dense point
- Time and space
- Flat
- the universe will expand forever, but the speed will eventually decrease to zero.
- Open
- the universe will expand forever
- Closed
- the universe will eventually stop expanding, collapsing on itself
- Cause another big bang
- the universe's density being less than the critical density
- the universe's density being greater than the critical density
- the force of gravity to stop the expansion
- it is accelerating
- another form of matter with strong negative pressure
- Dark energy
- play a part in the evolution of the universe
- it is believed the universe will expand forever
-
it is shaped like a saddle
- Open.jpg
- the universe's density being equal to the critical density
-
it is shaped like a piece of paper

- solar systems
- expand
- gravitational pull
- red shifting
- a result of light traveling through expanding space where the wavelength is stretched
- radiation (an isotropic radiation bath) with temp of 2.7 degrees Kelvin
-
it is shaped like a sphere

- cooled remnants of a fiery origin
- The Inflation Theory
- the universe expanded for a fleeting moment at its beginning at a much higher rate than was expected for the big bang.
- 10-35 seconds after the creation of the universe
