Time Travel

I've thought about starting a thread like this for a while. Anyway - I was watching a show on Egyptian mummies on Discovery Channel which were being used to study the diseases and immune systems of the ancient Egyptians and it got me thinking about whether Time Travel is possible.

After watching the show about the Ancient Egyptians and how 3,000 years ago the viruses that we deal with everyday - were extremely weak in their time. The show went on to say how if something like today's common cold was introduced to Ancient Egyptians - it could kill thousands. It's sort of similar to what happened when the American Indians first came into contact with Europeans. Diseases which Europeans carried around with them and thought nothing about - wiped out whole villages of Indians. A similar thing could happen if a person from the future went back into time.

I used to always think about the ramifications of time travel and whether UFOs are actually visitors form the future as well as a bunch of other theories on Time Travel.

What are your thoughts on Time Travel? Is it possible and what are the ramifications of it?

I've always believed that even if we could go back into time - we can't change the past - because the action which we'd take to change it - has already taken place.
