Philosophy is dead...?

Photons are massless. Although there is a question over that, but that's a topic for another day.

Mass travelling at light speed? :p

If you are interested in String and ultimately M-Theory I'd recommend The Elegant Universe if you haven't seen it already, very interesting read/watch. Why mavity is something like 10^11 times weaker than electro-magnetism is pretty mind blowing in M-Theory. Extremely simply put gravitons are closed stringed in nature meaning that they are not actually attached to the membrane of our universe and can travel through a multi-dimensional hyperspace. It's theorised that mavity is essentially so weak because it originates in a parallel universe which is leaking mavity into our own. :\

Zero rest mass then..:p


Thanks, I'll give it a read. I am currently reading a paper on Super-symmetry and perspectives on Higgs Physics by Prof Gordon Kane, but I'll have a look if my brain doesn't explode first. :)

Not really - just making a point. You know general discussion and all that ... takes a bit more than that to make me feel good but then I guess I'd have to consider what is good and what it is to feel that but I have always had my motorcycle maintenance for that kind of stuff ;)

Is that a euphemism for self medication...:p
 
I've been wondering that my self haha. And I just wondered if you were working in something to do with physics thats all. Turns out you're just a part time geek as opposed to a full time one. You wanabe!

Haha, to be fair my Brother is a fully fledged Physicist and my Mother was a Mathematician before she retired so it's probably in the genes.

I was more of the action man type tbh, though it would get me more girls.;)

Theology and Medieval History is more my bailiwick, which is why I am considering changing careers next year.
 
I dont think nothing can exist, if nothing did exist then something would fly in to fill that space. If the universe exists now the way it does, then there never was, any such thing as nothing. The universe always has been and always will be although maybe not in this form all the time.

Philosophy creates questions as long as we keep thinking and asking their will be philosophy, science cannot as yet probe the mind, even if it could there are many more questions.

haha, highly scientific approach there. "Something would fly in to fill that space" :).

It is a hard concept. But a harder concept is to think of what space really is.

Does a fish in a bowl look at the outside world and see our equivalent of "space" and presume it lasts forever. Are we just in a bigger fish bowl looking out with some big scary aliens looking in? Possible no?

Haha yaeh I bet you tell all the girls that you're the action man of the family :P.

We could be fish in a bowl but thats different to saying were fish in a bowl full of nothing. If there was a doorway right in front of you which opened into nothing, you could not see it. It wouldnt be black it wouldnt be white, its impossible to see. It couldnt absorb light, nor repel it, either way it would become something. Its impossible for it to exist in the presence of something. It could be like when you go out of a level in a game, the edges continue into infinity(the surrounding matter fills the nothing). Thats just my unscientific theory.

Nothing is really a concept that the human mind cannot envisage as a tangible construct. It is a mathematic concept.


For example the expansion of the universe doesn't mean it is moving into previous nothingness or getting bigger in a tangible way it simply means the space between objects is getting further apart. It is a difficult concept to explain simply.

What are the furthest most objects moving in to then? Space that already exists? If so, does that space cease to exist?
