Although my degrees are in computer science and computer engineering, as an undergraduate I switched my major over from physics after my first year. Before switching, I went through five quarters of undergrad physics, with my last class being relativity. I also had the pleasure of watching — and mocking — the Star Trek TNG series finale in a room full of other physics majors.
I love science fiction, not only for escapism, but also because it is fun to explore the hypothetical possibilities that science could make possible but hasn’t. Various topics like time travel and artificial intelligence have come up this year on The Non-Prophets, and I will usually drop into that kind of speculation at the drop of a hat.
I was wondering if you could help me with a scientific question. Recently, a friend of mine and I were discussing time travel. He stated that time travel is a proven fact and that there is evidence of this when you are driving in your car. If you look closely, time speeds up. I disagree but I cannot for the life of me remember the details, scientifically, on why this isn’t possible. Can you help me?
- Your mass increases.
- The energy required to speed you up more increases (that’s a necessary consequence of #1)
- Your localized time slows down.
