Universe Quizzes Online & Trivia

There are tens of thousands of galaxies and our galaxy, The Milky Way, is just one of them. Galaxies have many shapes and sizes; however, they have the commonality of gravity, stars, gases, dust, dark matter, and remnants of planets and stars that have exploded. Actually, the significant portion of galaxies are elliptical and are believed to have massive black holes right in the center. The universe contains all of space, including the many galaxies, planets, stars, and all other forms of energy or mater. The universe is such a vast expanse that it is a breathtaking collection of space and time, filled with everything you could imagine and some things you could not. The theory of the creation of the universe is an enigma in that there are so many theories, including scientific, and religious and not just one religion. There are many religions that have their idea of the formation of the universe.

There are a lot of cosmologists that are saying that the universe is still continuing to expand as time passes by. The galaxy is said to be expanding faster than light. Some say that this is inevitable and that it is meant to occur. The universe will keep on expanding and will keep on getting larger until such time when there will be no space to expand anymore. When this occurs, the big freeze will occur. This will signify the end of the universe. The expansion of the universe just proves that there are other solar systems and galaxies that are available different from our own galaxy. No one knows when the galaxy will stop expanding.

A stellar nebula BRADY OWENS

The CMB radiation was emitted 13.7 billion years ago, only a few hundred thousand years after The Big Bang. It was even before stars or galaxies existed. By studying the detailed physical properties of radiation, scientists can learn about conditions in the universe on very large scales, since radiation we see today has traveled over such a considerable distance. The supposition that the universe began in a microscopic super dense, hot state, which expanded into the cosmos we know today is called The Big Bang Theory. The early state implies that the universe should be full of radiation. When the universe expanded, the radiation cooled and is now blackbody radiation of three degrees. When the background concerning radiation was discovered, it supplied a fair amount of evidence that there is some truth behind the theory.

Some of the sicintsts believe that there is multiverse but they dont have evidience that its true and its completely fine if you dont believe but if there is multiverse alot of things are going to change in our phisics.  

I always thought water in the form of ice comes from comets (the Kuiper belt)

1. A faint star of enormous density.

A very big collection of matter,mostly gas compressed to incredible pressure and heat by gravity.

Multiverse is infinitenumber of parallel universes and universes.

The exact shape of the universe is still a matter of debate among scientists. The shape can be described by the critical density. If the density of the universe is more than the critical density, then the universe is closed and curved like a sphere. If the density of the universe is less than the critical density, then the shape of the universe is curved like a saddle but if the density of the universe is equal to the critical density, then the universe is shaped like a flat piece of paper.

There are some people who wish that they would be able to reach the edge of the universe but they are not sure how they are going to do it. Some have speculations that when you reach the edge of the universe, you might reach another universe and live there. The question is, is there some sort of technology that will make this possible? There is no rocket that will be able to travel space and the whole universe in a short amount of time. Most planets would take years before they can be reached. Some of the areas of the universe cannot be reached by people in their lifetime.
