Reply to comment by Arcanorum in NASA satellite discovers second Earth-sized planet in habitable zone by Tuna_Sushi

That’s a long to say you’re speculating 😂

Edit: yes, I’m specifically referring to your speculating on matter going the speed of light, and yes I’m still laughing.

Time dilation as you approach the speed of light is not speculation, it's fact. Time slows down heavily the closer you approach lightspeed and does not pass at all for anything that can actually reach it.

Any discussion of matter going the speed of light is speculation, because it is impossible in our current understanding of physics.
