the presents of a photon in time and space.

To the best of my knowledge, photons have no mass, so their presence differs from that of massive objects (matter). Photons are indirectly affected by gravity only because gravity bends the space through which they travel. Photons are similar to sound waves in that their numbers aren't conserved.

What kind of presents do photons give? Expensive presents, joke presents, thoughtful presents?

No need to be so particular. Just wave at the giver, eh?

Given the fact then that energy has no substance in the form of being a photon ,there then cannot exist the same relationship to time and space as mass does to time and space So energy emited as a photon must go into a new existance in relation to the fabric of timespace it occurs in. In other words the photon takes on a more gravity like nature to timespace fabric.

Do you mean "no mass"?



Yes, that's what I said.



That's a pretty flamboyant way of expressing it, but if I understand you correctly, yes, energy manifests itself differently from matter.



This is where you lost me. Or, one of the places. How do massless photons "take on" more gravity "like nature to timespace fabric"? This seems to be a meaningless jumble of words. I'm guessing that English is not your native tongue, and I would never criticize anyone for that, but I request that you please explain your intended message in clearer detail.

Thanks fbm for that conformation. What I ment about gravity is that it seems to be a balance between mass and timespace. Gravity is time space trying to neutralises mass in timespace.So the photon seems to find this same new balance with spacetime on becoming a photon which is the c limit.

I'm going to be perfectly honest here and admit that I can't figure out exactly what you just said. For example, is "timespace" the same as "spacetime"? Consistency in terminology would help us communicate. I don't know what your native language is, but I can only speak/write in a few, and only but a couple of them are very popular.

I love the 'presents' pun - it's up there with 'some day my prints will come.'

Ok setanta or should that be santa. Crimbo joke ho ho. Sorry santa ho ho ho.

I hope this helps you understand photons:
