Myouya Posted September 13, 2018 Share Posted September 13, 2018 Here's a problem to break your mind. Say you have a rotating door (you know, those in malls for example, where you push and as it spins you can access the other side). Heck, here's an image just to make it clear. So, imagine somehow you manage to accelerate the panels 99.999% the speed of light when calculating the spin speed of the panel at the closest point to the center. Knowing the points on the borders of the panels always technically move faster than the points closer to the center, would this break any law, or what would most probably happen? Are the panels at the edge kept from going any faster by some force and hence break apart from the whole door? If I didn't explain this well enough, do let me know and I'll try to rephrase it or make a drawing to illustrate it. Link to comment Share on other sites More sharing options...
brycec Posted September 28, 2018 Share Posted September 28, 2018 I do not know that the rotating door thing works out too well (need more members to add things in), but I think that it might be the similar to centipetal force, which is what keeps you in a roller coaster. You did remind me though of how something about scissors might be faster than light. The scissors themselves are not FTL, but when they close, the intersection that is noticeable by going as wide as you can tends to snap down quicker than the rest of the scissors and that is what might possibly be FTL.

Beocat Posted September 28, 2018 Share Posted September 28, 2018 Considering that all our math starts to break down as you approach the speed of light, it means we are probably missing something important in the equations (so perhaps there isn't a limit but a transition that occurs instead). We still cannot fully explain black holes (which have photons spiraling into them, which were already moving at the speed of light) so our astrophysicists and theoretical physicists still have a lot of work to do.

The scissors problem takes a made up point however, it’s not real information traveling the distance. 3 hours ago, Beocat said: Considering that all our math starts to break down as you approach the speed of light, it means we are probably missing something important in the equations (so perhaps there isn't a limit but a transition that occurs instead).

Aye aye, that’s where the fun is, hehe. Link to comment Share on other sites More sharing options...
the_twig Posted September 28, 2018 Share Posted September 28, 2018 Theoretically, it is possible to create very specific situations to make things go faster than light. In reality though, it would be damn hard. The energy required to accelerate it that much is insane, and no material that we're aware of is strong enough to withstand the forces, not even graphene.

That makes sense. It is still neat to think about things like faster than light though. Link to comment Share on other sites More sharing options...

Hehe, yeah. Messing with physics is entertaining. *Blows up the universe by accident* Link to comment Share on other sites More sharing options...
