Does light have Mass?

Yes I understand that there are many diferent substances that are still being discovered. Im just trying to figure out how to grab or move something that is mass less I am not sure if I am putting the question plainly. If you understand the question or if anyone does, and are able to restate the question in a more appropiete manner please help me out

Rest mass is zero of photons however they do have the mass of the energy they are carrying. energy as in mass=energy.

Ok now were talking. So even though the photons themselfs have no mass. They how ever carry something that consists of mass. And thats whats being tugged and pulled. Thats what you mean BillRM?

YES ......................however it is never that simple in Physic beyond Newton but in the main yes.

Aha now that makes sense. Thank you BillRM.

yeah, as Einstein said, Quantun Physics = Spooky

Fear of the unknow?

the unified field theory has yet to be unified.

You Rock From the posts I read. You can open alot of minds by trowing diversions on topics. I love that And that humor is priceless

Energy is truly unified; and only the warped theoretical science of mankind that divided and tore it apart. The solution can't be found because it simply just is.

"According to the current doctrines of mystic scientism, we human animals are really and actually Nothing but organic patterns of Nodular energy composed of collocations of infinitesimal points oscillating on the multi-dimensional coordinates of the space-time continuum. I'll have to think about that. Sometime. Meantime, I'm going to gnaw on this sparerib, drink my long-neck Bud, and contemplate the a posteriori coordinates of that young blonde over yonder, the one in the tennis skirt, tying her shoelaces."

ROLF Priceless I tell ya priceless

No, it's that quantum physics does not work the way you expect it to (saying that in the simplest way possible)

It does spooky things.

Light does not have mass, it appears to be pulled by black holes because light travels in a straight line with the "straight line" being relative to the space it is traveling through. If space is being pulled through the black hole then light will follow the same path through space that would have been straight if not affected by the black hole, giving the appearance of being pulled in by the black hole. So basically it the light is not even affected by the gravitational pull of the black hole, only it's path is.

Ok fair enough. How do you then explain the Bose Einstein condensation effect then? When you shoot a laser light thru it. It is slowed down. I think the proper thing to say would be 'photons' dont have mass. But energy particles associated with light do have mass. So that can it be tugged or pulled. So light as a whole and all it may comprise of does have mass. Photons however do not. I am not educated in these matters, but from the people that are, thats the answer I think I got. Have you come up with the same conclusion after reading their discussion?

Light doesn't really slow down. It's speed in a vacuum is always the same. But when you pass light through a material (even a BEC) there is absorption and emission which makes it appear to "slow" down.

not sure about light having mass, but mass has lights

Light does not have mass.

Nothing that moves at the speed of light can have mass, and nothing that has mass can move at the speed of light.

Rework your posting as follow for it to be correct:

Nothing that moves at the speed of light can have rest mass, and nothing that has rest mass can move at the speed of light.

Ok then does the light wave' carry energy? Does energy have mass?
