- TL;DR Summary
- why can’t you push something that’s massless with a finite amount of energy to make it travel infinitely fast.

I feel like if something is massless it should be able to travel infinitely fast with any amount of energy. When you have something with mass, you would need an infinite amount of energy to push it infinitely fast, but if the thing you’re pushing is massless, you should be able to push it with a finite amount of energy to make it travel infinitely fast, but you can only push it to about 300,000 km/s, why?
