“All our sweetest hours fly the fastest.” -Virgil
The speed of light in a vacuum is the limit for massless particles, but massive ones are limited even further! Have you ever wondered about that?
We can get particles in accelerators up to 99.9999999988% the speed of light, and the Universe makes ones that are even faster! But despite all of this, there’s a limit, and that limit is more restrictive than the speed of light in a vacuum!
What is it, and where does it come from?
Go read the whole thing here, and try not to go that fast, even in your sci-fi dreams!
