I understand the formula my statement was about an object traveling faster than light then its Lorentz factor would be a mathmatically correct but physically nonsensical answer. Even the formula about for the relationship between their times doesn't work when Alice is traveling faster than...
Dr. Greg I appreciate the link. It was close to what I was looking for. I had previously tried to use the Lorentz factor to show myself why something would move backwards in time but I couldn't reconcile the fact that anything other than a specific set of numbers produce negative time. Some...
I understand that the questions behind causality and FTL have been brought up numerous times, and I have read several of the old threads. My question isn't with how is causality violated, it is always assumed that any signal sent would appear to travel backwards in time from one point of...
Now I know it's been a while but all of the metrics seem to take into account things coming out of it without also considering the fact that anything leaving would have had to enter first. Am I right in this observation or has the time since having looked over those metrics extensively caused me...
Hello my name is Stephen. I was in college planning on double majoring computer science and physics when my wife got pregnant. I had to leave school to support them but tried to stay current with both fields. Unfortunately working and being a father doesn't leave much time for learning and...
I haven't had the time these last several years to go back over the equations for wormholes so could someone please remind me why you would need negative energy to hold one open. The last time I asked a professor about it they explained it badly with something about how you energy expanding as...
