It isn't faster than light, it's just faster light!

Speed of light between two points is probably not going away :)

Light traveling at infinite speeds, atoms and such not.

What does it have to do with the speed of light?

orjandus May 30, 2023 View on HN

well, you can't go faster than speed of light?

FrancoisBosun Apr 15, 2019 View on HN

I thought nothing could move faster than light?

IceyEC Apr 18, 2018 View on HN

Stuff can't move faster than light, but space is bound by no such law!

tomklein May 19, 2021 View on HN

Wouldn’t that be way faster than the speed of light?

grishka Jan 26, 2023 View on HN

Does this still assume that the speed of light is a hard limit?

Not if you traveling by the speed of light
