I've said it before in a thread on this very site. It isn't that hard to understand really...

1) Light has mass.

Gravity can only pull on things that have mass. Gravity can pull and bend light...ergo light must have mass. But here's the problem I have with that. Force equals mass times accelleration, and that SHOULD cause an issue. I'll give you an example...You go home to a dark house late at night, turn on the lights in your living room...and you still have a living room.  Regardless of how small the amount of mass light may have, it's travelling at 186,000 miles per second, and therefore should destroy anything it comes in contact with. Why doesn't it? Back burner that thought for a minute...


Oh yeah... I forgot that one...  Embarrassed
But isn't the space-time distortion caused by objects with mass that causes the light to bend, being that, if we take space as a 2D deformable plane and light constrained to moving in paralel line to the plane that's possile, light doesn't necessarily have to have mass.


I don't know, is the space-time distortion caused by objects with mass that causes the light to bend? Why make it harder than it needs to be?

Don't know... I think because Newtonian gravity needs both bodies to have mass for one to affected by the other and the distortion theory doesn't...
I still have a lot to learn on this... Good thing I'm taking a physics engineering course!  Grin

Correct on many things Groundbound1.  I don't think from my knowledge of quantum mechanics and quantum physics that I could find any flaws in all that except for two possible things.
1.  "light itself breaks Einstien's theory"  well, what if the impossibility only applies to solid objects that are above the level of being classified under quantum mechanics/physics?  Becuase remember, light also acts as a wave.

2. "as an object approaches the speed of light, it becomes more massive" Here, I think you may have just misunderstood.  According to Einstein, the closer something goes to the speed of light, the more mass it gains.  think realative to the mass that is closely related to weight, not size.  And actually, he also hypothesized the the closer to the speed of light you go, the more the object will actually decrease in length realative to the direction it's heading.

(If you're wondering, I read STRANGE things for my age.)

But of light having mass:
One example of light having mass is black holes.  I would go on explaining the entire possible processes of black holes as Stephen Hawkings says, but that would take up way too much space and probably exceed the character limit, but basically, according to Stephen Hawkings, black holes are usually quite small, have an absolutely HUGE mass, and have such a strong gravitational pull that light cannot escape.  The only things that escape from black holes are X-rays and gamma rays. (if you want a much more in-depth description, let me know)

But all in all, I'm loving all this talk about passing the speed of light and am quite exited. Smiley

All I hope is, from what I've heard, if you can travel at/past the speed of light, you can travel through time.  I'm worryed about someone actually trying to do that.  With that, you could deal with time loops, lunatics trying to bring back something like the 3rd Riech or something like that.(I think i spelled that right)  And also, a slight change in the past can massively alter the future.

My pet theory is that when you exceed the speed of light, you cross the dimensional barrier and are no longer in this dimension. At least until you slow back down below the speed of light,

at which time you cross the barrier again, back into this dimension. The only question I have, is how many dimensions are there, and how to change places with myself in the one where

The equivalent to squeeze the entire earth until the atom's themselves collapse, that is, until the earth is the size of a small glass marble. But anyways, why do you keep saying that for light to be affected by gravity it must have mass?
I know a little of newtonian physics but the space fabric distortion seems a bit more complex, but simple at the same time, if we take the universe's shape as a 4 dimensional sphere. In the space-time fabric does the second body still need to have mass to be gravitationaly affected by the body with more mass?

Here:
Quote:
The photon is currently understood to be strictly massless, but this is an experimental question. If the photon is not a strictly massless particle, it would not move at the exact speed of light in vacuum, c. Its speed would be lower and depend on its frequency. Relativity would be unaffected by this; the so-called speed of light, c, would then not be the actual speed at which light moves, but a constant of nature which is the maximum speed that any object could theoretically attain in space-time.[19] Thus, it would still be the speed of space-time ripples (gravitational waves and gravitons), but it would not be the speed of photons.


http://en.wikipedia.org/wiki/Photon

So, if what I quoted above is true, then the speed of light hasn't been breached because if photons have mass they can't travel at c...

Club508, I glad to see you take an interest! (I'm really impressed) Backtrack a little, and read what I wrote again, begining to end, then read what you wrote.

Keep in mind two very important points:
1) I don't by any stretch of the imagination have all the answers. This is a very ROUGH theory, nothing more.

2)You have to let go a little, and stop accepting what Michio Kaku says as fact. Not to disrespect or discredit him in the least, but he is just like any other theoretical physicist, a master of assumptions and educated guesses.  Wink

Because, without mass, what is there for gravity to "grab ahold" of? Anything that has mass, has gravity. Anythng that gravity can influence, has mass. It is just that simple. Two sides of the same coin. Gravity is proportional to mass. A rough idea of this concept is the Earth vs. the Moon. Moon= roughly 1/6th the mass of Earth, Moon = 1/6th the gravity of Earth.

They aren't traveling AT c, but faster, thus bypassing 3d space altogether, and because of this IDEA (and that's all it is, and idea) it's no longer subject to the governing laws of physics as we know it. In some respects, you need to forget conventional thought and what is generally accepted, and think outside the box. Look if there is any truth to any of this at all, the books are going to need a complete overhaul. Nearly all of physics has been based on theories that were based on other theories that may now be more flawed that we thought. That's one hell of a ripple to recover from.

Heck, problem is that's confusing all of us between all our seperate theories due to all our seperate resaerch is this.  I don't think I have ever ONCE read anything about sience that said anything about theories with this, and state them as facts.  By the way, I have absolutely no idea who Michio Kaku is.  i haven't even ever heard his name before.  And that's a perfect example of all the flawed theorys on flawed theorys on flawed theorys and so on and so on.  And then all those theorys could be based on something mistaken due to someone stating something like its a fact when it's really only a theory and thus convincing anyone else who reads it that it's a fact. Tongue
And I only thought of all that after what I posted.

All in all, too confusing, and with too many theorys. Lips Sealed

lso remember as you approach the speed of light the drag becomes phenomenal. Take it this way. A Bugatti Veyron needs only 250hp to get to 150 mph, But needs 1000 hp to get to 250 mph. light travels at 670,615,200 mph which is, Allot Shocked I might be doing my maths wrong though Undecided.
But anyway:
That drag and weight combined could be fatal. But what ever we do, We'll never escape a black hole Smiley. Eats even light  Shocked.
Plus time goes allot quicker (The faster you go,  the slower time flies). So if you're on that light exceeding body for a minute, About 20-30 years e.t.c may have passed Shocked.
So another way to do it is not to try to get from point A to point B, but to bring point B to point A. Therefore bending space which is kinda dangerous. But that would take up A HUGE amount of energy and the effects of the aftermath are unknown. And If it's successful and you do make the "jump" you never know where you will emerge. And I'll go on and on.
And another option that sounds similar but is quite different, is teleporting. Which is in short destroying your body and recreating it at another point.
But again Regardless of the risks, scientists will do it. They are only concerned if they CAN do it. Not if they SHOULD do it Sad
Sorry. I'm one of the geekiest and Most made fun of boy in school Embarrassed.Edited:
