And it is remarkably consistent at doing that.

Relatively consistent.

Yes, but light always travels at the speed of light, regardless of its speed. It travels at c in a vacuum.
mexicancartel@lemmy.dbzer0.com 3 months ago
But when you think about light’s speed in medium it seems like absorption and re emission which shifts light’s net velocity. The speed of light between the interaction is still c. That becomes obvious if you zoom into matter and find its mostly empty likr vaccum

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!

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.

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.)

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.

Any speed that light travels is the speed of light
Elgenzay@lemmy.ml 3 months ago
The real breakthrough
bjoern_tantau@swg-empire.de 3 months ago
The other way around. Experiments said that light always moves at C and he deduced what follows from that for space time.

Yeah, but is it a wave or a particle, eh, Einstein? Answer that!
AlbertEinstein@lemmy.world 3 months ago
Yes.
niktemadur@lemmy.world 3 months ago
Holy Minkowski spaces, Batman! It’s the old man himself!
bjoern_tantau@swg-empire.de 3 months ago
Well, he did get a Nobel price for saying it’s a particle.

Uh, Einstein was Jewish and Hugo Boss made the SS uniforms. This is a bit odd.
Ostrakon@lemmy.world 3 months ago
How on earth would an average person looking at this pic of Cavill know it’s Hugo Boss?
nightwatch_admin@feddit.nl 3 months ago
I am sorry, I thought this was a Hugo Boss ad and that that was the joke. I have never heard of Cavill?
niktemadur@lemmy.world 3 months ago
Put a monocle on him and make it The Speed Of Causality.
Kvoth@lemmy.world 3 months ago
Uh, that discovery actually predated Einstein. He simply explained how the speed of light was constant for all observers
DasFaultier@sh.itjust.works 3 months ago
You mean Mileva Marić and her husband?
Kvoth@lemmy.world 3 months ago
I was blanking on her name. Sadly she is almost never given the credit she deserves
stupidcasey@lemmy.world 3 months ago
Einstein proved time is relative just so he could take credit for it
