The Universe
The Universe is defined as everything that physicallyexists: the entirety of space and time,
all forms of matter, energy and momentum, and the physical laws and constants that govern them.
The Universe is massive. The human mind cannot imagine or calculate how massive the universe really is.
We may never know the exact size of the Universe. Is there even an exact size at all? Who knows?
The Hubble Space Telescope (HST) site estimates there are hundreds of billions of galaxies in the universe.
There are probably billions of planets out there with life on them...
We don't know this for sure. What other life forms would YOU like to see?
I would like to see Lombaxes. A whole planet full of them. That would be so cool.
You can also post pictures if you can't really describe it in words.
Each spec of light in this image is an entire galaxy.
