We can't reach it, correct? If we could then time would stop inside an object moving that fast, which is just weird. However, we can't reach 99.999....% of it either because 99.99999.... = 100 for the same reason 0.999... = 1. So how close can we get?

 

Some of the many proofs 0.999... = 1

If you need more I can send them.....

 

It is time people just accepted it and moved on.

You can get arbitrarily close, i.e. within some finite but small value, given enough energy.

0.999 recurring for infinity is 1 but the number of nines in the 99.999(etc)% of the speed of light we can reach is finite. meaning that the proof above does not apply because it is not the same scenario at all.

 

we are limited by the amount of energy you can put into a single particle. if you put ALL the energy of the universe into the lightest known particle(a neutrino) it still wouldn't be at the speed of light but slower.
