No Stupid Questions@lemmy.world•Since light cannot pass through a black hole does that mean light has mass? Also why does light form a singularity in a black hole? Is that like a fixed point on a map or something?

Interstellar was somewhat correct about the event horizon. In theory there also could be an escape velocity but since nothing moves faster than light nothing can escape it. Since light (speed). is the ultimate barrier for velocity.
And every mass bends the space, the small the mass the small the dent.
In science fiction and with a real theorem people “move” faster than light. But using the Alcubierre drive would require so much energy that it is (for now(?)) impossible to achieve. The drive also doesn’t propel the spacecraft faster than light but bends the space around it, so technically you would more so move the space around you, instead of traveling though space.
