Physicists Claim Time Travel Is Impossible (This Time, They Mean It)
from the in-case-you-were-hoping... dept
Discussing the physics of time travel has come into vogue recently. Even Stephen Hawking -- who admitted he used to fear being labeled a "crank," if he discussed the physics of how time travel might be possible -- has explained how time travel might work (and revealed his desire to go back in time to see Galileo... and Marilyn Monroe). However, some new research states what most of you probably already thought: time travel is a physical impossibility. While I agree that seems likely, I have to admit that I'm a bit amused that the LA Times article about this seems to assume that because it's in a "peer-reviewed scientific journal," that makes it the unquestioned truth. And, while I, once again, tend to agree that it's likely that time travel is impossible, there have been plenty of other things declared impossible by scientists that later proved possible. Remember, Lord Kelvin declared "heavier-than-air flying machines are impossible," just eight short years before he was proven wrong.
