Are Photons REALLY Massless? #photon

Do photons have mass? Every science book you've ever read says that are massless. But we don't really know that to be true.

[stevemeisternomic]

This is exactly as I thought. Just because you can't or are unable to measure something doesn't mean that it is not present.

Understanding photons is the key to greater/equal to light speed travel

An extension to the Standard Model is that the chances of typos are proportional to text size - in this video also Blue shifted :)

but the fact that gravity is also limited by the roughly 300, 000km/s kinda shows that unfortunately our universe has a speed limit and that speed limit is extremely slow. we cant even have a proper phone call with people on our neighbour planet and we cant play fast paced games with people on the same planet if the people are on the other side of the planet. the speed limit of our universe seems to be pathetically slow

I thought it was proven that photons does not interact with higgs boson?

[Bartjebom_]

I have questions...
Can you "catch" light?
What if you have a closed sphere with mirrors ... and beam light in it captured.... does light stays light? Or does light dissapear without its source?
And if light have no mass why can light be bended by gravaty?

I love your channel 🌌🪐
Kind Regards bartjebom

Shine a light in a cup and see if you can gather any. No, I guess it doesn't build up so no mass. Let's move on.

[jimmicrackhead]

In other They have no idea and make everything up- that's why it's all called

[TheNewPhysics]

You don't know what mass is...:)
So... it is not surprising that you don't know if photons have mass. The same goes for neutrinos...:)
If you want to know the answer (a theory where mass is properly defined), search the Hypergeometrical Universe Theory ...:) Accept no substitutions...:) There are plenty of plagiarizers, and crackpots that added Hyper to their copycat models

Photons almost have to have a small mass or a black hole wouldn't be called a black hole. There has to be something for the gravity well to effect.

[kanedafish]

Sounds like a conundrum for the whole mass = energy thing

[sreejithm]

Can it be calculate in a blackhole, since it absorbs a large quantity of light, ?means, a large number of photons....🤔

[rockyholms]

Can someone explain solar sails to me then cuz I always thought photons had mass and that’s how you get force in a solar sail I think that’s what it’s call lol cuz F=ma right so if you got 0m x 300, 000, 000m/s^2 you’d get 0F right? I feel like I’m doing F=ma wrong also lmao

[nathanroberts]

Dude you explain things nerds like me want to know. I'm a dumb nerd, i love physics but I'm not a physicist. I own a damn construction company and everyone i talk to about physics could absolutely care less. They just don't understand how truly awesome cutting edge physics are!

[moonfly]

What if photons dont move. What if the universe is full of stationary photons that can exist at basically absolute zero (sort of cloaked) all packed together like water in a pool that we interpret as dark matter and energy just transfers like balls on a pool table, and we simply detect this interaction as "movement" and the speed of light is actually just our speed of perception based on the speed energy transfers between photons like electrical current on a wire. That would kind of explain why light acts like a particle and wave too, at least to my basic brain anyway 🤷‍♂️

[wilurbean]

That's not true. We don't know the speed of causality by which to compare light's speed to.
We know that it has a kinetic mass as well.
We don't know the size of an electron either, but saying it's a "point particle" is nonsense and would make it a singularity right?

[TGiFoosday]

Funny that photons being so much "nothing" still comprise a lot of "Energy".?
And enough that we can make solar sails accelerate a "mass" to high speeds in space. Personally, I think that if there wasnt light, time wouldn't exist either as there would be no way to perceive changes or entropy or causality happening. Wonderfully weird universe we exist in, for some reason(s).

[rickianggoro]

Photon is the saddest particle in the universe. Immortal but so lonely... Cause travel with speed of light, the size of everything is zero. So, it cannot feel time. It goes to anywhere in an instance...

[uncletiggermclaren]

It is pretty cool to think that such a fundamental, easily experimented with, and omnipresent "part" of nature has such an OBVIOUSLY important aspect of it "unknown".

[ianclarke]

E=MC2 we already know that energy and mass are one in the same. Now view the universe from the perspective of any of those particles using special relativity, it all makes perfect sense then.
