The Fermi Paradox

The Fermi Paradox..

>The Fermi paradox states that it is improbable that aliens walk among us...!

_The paradox states that although intelligent life probably exists, there is no evidence that aliens are among us. Similarly, the fact that there are no visitors from the past or future means that time travel may never exist.

_The theory of relativity is an umbrella term for two theories -- special relativity and general relativity. Special relativity states that all motion is relative. General relativity states that gravity is a property of space and time, keying off of Isaac Newton's law of universal gravitation. General relativity also allows for backward time travel in certain. unusual circumstances.
