Change My Mind

Well yes but actually no

How

It's relative: from the perspective of the person who is travelling at the speed of light (somehow), time stops until they slow down, but from the perspective of a relatively stationery observer, the lightspeed traveller's journey still takes time, as lightspeed isn't infinite, 'only' 3*10^8 m/s.

I didn not understand a word you said but you successfully changed my mind

And so true teleportation cannot be achieved

Lol it shows my comments backwards
