Can Light Be a Product of Higher Dimensions?

[Unit_Zer0]

hi I'm new, i was doing some pondering after watching a show about new modes of transportation. one of the modes was for space travel and using solar sails. in the show it was stated that the main force would be from light emitted from the sun. i thought that was cool, as it was explained (and shown) that photons exert force upon the sail itself in a similar fashion to wind and conventional sails. i got to wondering how much does a photon weigh if anything. i say if anything because force = mass*acceleration. well at 186,000mps you'd think that we would be crushed by light. here's my question is it possible for light to actually not exist within known dimensions? that perhaps light is a product from the 5th dimension that warps the 3rd and 4th?

now for the biggy, do i sound stupid?

please forgive my lack of knowledge, if photons are massless and do carry momentum and can exert force then your getting something for nothing (this doens't include the source of the light)am i incorrect in assuming that? and about the 5th dimension thing, i guess I'm asking is it possible that photons cannot be measured because they do not originate with in the 1st 2nd 3rd and 4th dimensions? from what I've read and you've stated they shouldn't exist but do. and by warps i mean warps causes an anomoly that eye's pickup as light. but once please forgive my lack of knowledge.

by something for nothing, if photons have no mass then how can a object with no mass have momentum, and exert force? which actually brings up another thought if photons(light) have no mass then how can they become trapped in a black hole?(ignore the last one)

and by measured i mean their weight i mean, the actual mass of a photon. and finally i don't know its late for me, and I'm tired.(22 hours and still going sluggishly.) it just doesn't seem right that something can exist without any physical properties. and why shouldn't there be anomolies that cause light instead of the direct assumption that light is photons being absorbed? i'll get back to you on it in say 12-20 hours.

ps i see where yer coming from but puting what I'm thinking into words is proving to be much harder than i had first anticipated.

Not really that silly a question can see how it is that u got confused, for i myself was also confused by that, couldn't get my head round how a particel with no mass could have momentum but eventually i did, so its not such a stupid question afterall.

Why did i bother typing that crap?

if it has wieght, doesent it have to have mass,


F=ma

where f is the weight due to gravity, a accelration, and mass...so if photons have no mass...how can it have a force
