He also discovered that the speed of light equals c.
Where c is defined as the speed of light
And that’s why we take vitamin C!
Uh, that discovery actually predated Einstein. He simply explained how the speed of light was constant for all observers
To be more accurate actually, he and his first wife explained it
You mean Mileva Marić and her husband?
I was blanking on her name. Sadly she is almost never given the credit she deserves
Einstein proved time is relative just so he could take credit for it
Yeah, but is it a wave or a particle, eh, Einstein? Answer that!
Yes.
Holy Minkowski spaces, Batman! It’s the old man himself!
Well, he did get a Nobel price for saying it’s a particle.
I’m reasonably sure that Einstein’s breakthrough was more that he assumed light only travels at the speed of light and the all the equations worked.
Every experiment since has confirmed it.
Technically everything moves at c (the speed of light) through spacetime, all the time. Most objects that have mass spend the majority of their motion in the time part, and thus move relatively slowly in space. If an object moves fast in space (where fast is a significant fraction of c) then it moves noticeably slower in time because the total spacetime vector value is always c.
Photons, being massless, do not move through time at all, and move through space at c.
To add to this, this is always relative to an observer. If an object moves fast in space compared to you then it moves slower in time compared to you.
That’ll break a few brains. To elaborate with an example: From the perspective of a photon, it’s “life” is over as soon as it begins. Even though it takes about 8 mins for a photon to travel from the sun to the earth from our perspective, no time at all has passed for it.
(Correct me if I misspoke.)
Any speed that light travels is the speed of light
The real breakthrough
The other way around. Experiments said that light always moves at C and he deduced what follows from that for space time.
And it is remarkably consistent at doing that.
Relatively consistent.
*in vacuo
Yes, but light always travels at the speed of light, regardless of its speed. It travels at c in a vacuum.
Dispersion and nonlinearities would like to have a word ;)
Light is never late, nor is it early, it arrives precisely when it means to.
Put a monocle on him and make it The Speed Of Causality.

“Fuck you photons, next time. Again.”
