Does light have Mass?

E=M (large number here) .
If you say photons are energy, and mass equals energy.
Lol . If you read what is said "photons contain zero mass at rest". Every physical item has mass.

Then heat has mass..

Krumple, read his profile, you will see that reality, need not apply.

Again, this thread is about the search for the mass of a photons and space, but no matter how many people tell you something, you just reply back with another question.

Pete, you are never going to answer questions, that all the worlds best physicist can not. You can be interested, but demanding to understand the universe, is a guaranteed fail. You must accept this,

@Krumple,

Yes! The physical world has mass at different states!
The chair you sit in has mass at rest while the light you see has mass that is not at rest.
You can't describe something physical with any negative dimensions. That includes the structure's composition.

Pete, only a noodle could understand that.............................

If you have any person around you that knows how to read a tape measure, I am sure that they can try to explain to you why structures with negative dimensions don't exist.

Actually, there is no physical world at all! So, there is also no mass,
There is only light ( waveforms) that we decode if we see a chair or something else. We are really living in a hologram).

To get a feel for this, watch the movie "The Sourcecode)

Einstein's son seemed like a nice guy also.
Sure you are right, I see lots of people who watch cartoons for hours. So it should be easy to find such a topic to discuss.
This one is about describing the physical world.

Who said that structures with negative dimensions do not exist? I never did, and you will be hard pressed to make the claim, that I did.

To describe something that has zero mass, is the same as saying that it has zero volume or zero width.

Pete, perhaps you are just not intelligent enough, to grasp the concept. Can you do advanced mathematical equations? If not you may not be able to understand, how a photon behaves and why.....

@DNA Thumbs drive,

Are you claiming that a photon is made out of nothing?

@peter jeffrey cobb,

How can something go thru glass and walls without effort, have a solid structure, and if the photons from the Sun had mass, why is it not accumulating on the Earth. Say burying the pyramids by now?

Being that 5% of the Universe falls under the luminous category, that leaves 95% left that falls under "dark energy, etc" categories to be explained.
Just so happens that those categories are growing in volume.
Photons can be partially absorbed by certain structures that are not glass.

What structures are photons not partially absorbed into?

@peter jeffrey cobb,

Why?

Answer, because you can not make sense of it, so I should bother..................

You really are a prick, aren't you? It's one thing to hurl epithets,as I have done to you many times, but it's weird to realise that they are actually true.

Why is 95 percent of the universe believed to be missing, since no one ever saw it to begin with???????????????????

@DNA Thumbs drive,

This is a discussion. You are asking the general public.
I can try to help you find your answers, but you got to at least show some effort by reading the answers to your questions.
