The Best Astronomy Topics


Worm Holes:

The definition of a wormhole is a theoretical distortion of space-time in a region of the universe that would link one location or time with another, through a path that is shorter in distance or duration than would otherwise be expected. To translate it so that you could understand it, it is a "shortcut" through space and time. A wormhole has atleast 2 mouths that are connected to a single throat. There is no observational proof of a wormhole, but it can be a valid solution inthe theory of General Relativity.


Dark Matter:

Dark matter can be explained as unseen matter that could make up more than ninety percent of the universe. As the name implies, dark matter does not interact with light or other electromagnetic radiation, so it cannot be seen directly, but it can be detected by measuring its effects [gravitational]. It is believed that dark matter was instrumental in forming galaxies early in the Big Bang.


Ultimate Fate of the Universe:

The ultimate fate of the universe is a topic in physical cosmology. Physical cosmology is a branch of astronomy that studies of the large-scale structure of the universe and is concerned with fundamental questions about its formation and evolution. Many possible fates are predicted by rival scientific theories, such as the big rip, the big crunch, big bounce, and etc. These have all been developed my various scientists.


Milky Way Galaxy:


The milky way is the galaxy containing the solar system, visible as a broad band of faint light in the night sky.It is made up of comprising an estimated 200 billion stars, and is estimated to be 13.6 million years old. (about as old as the universe) The entire galaxy is rotating about the Milky Way's center. It has made many changes since it was developed.


Star Constellations:

Any of certain groupings of stars that were imagined by those who named them to form images of objects, mythological figures, or creatures in the sky. They are useful in helping sky gazers and navigators locate certain stars. A constellation's stars are often designated by its name and letters of the Greek alphabet in order of brightness. I think that it is stupid that they try to make pictures out of the stars, but that is just my personal opinion.
