Question:
I have heard on the news that some scientists say it is possible to travel
travel through time. Is this really possible?
Replies:
That depends on what you mean by "possible". Theoretically, I suppose time
travel is "possible", but there is no scientific evidence for it. Here is
something to think about though: suppose time travel into the past is
possible and is discovered in the near future. Then why have not people in
that near future traveled back to our present and told us about it?
