liz - i must agree with you on bot subjects
light a wave of particles - yes i think that is the best way to describe it.
as you say if it is a particle it must have mass, and i dont think you can weigh light, or can you?
also an property of a particle is it can most likly be containded, and you cant contain light, can you.
well maybe with a box of mirrors, hmmm might be nice experiment, capture light.........
step 1
get a box of mirros facing inwards
step 2
let light reflect in it and close the box
step 3
see if you havecontained the light......... urhmmmm, how can that be done if you cant look in it cuse it will go out if you open the box...............
............
...........
...........
...........
never mind that
on the subject of gravity, i also think you are right liz.
it think its only a result of a process.
as for the process.
i have no idea why it works....
the main thing is said to be the spin of the earth that is suppost top keep us here, but if some thing spins it should move out words right?
what a coincedens i have been watching a documentary about sme thing like that.
it was about the universe expending.
the main thought was that when the BIGBANG accured the univers was moving away, but as all things due to gravity it was thought that when the exploson took place and the planets and galaxies drifted away, they would also come back to the centre again, resulting in a BIG IMPLODe or some thing like that.
in adition the the expansion of the universeit was suppost to slow down and return again.
taking this in notice scientist have taken pictures of supernovas of a special type and calculated the speed and distance and more of that stuff.
but they found out hte universe is actualy accalerating.
they have come up with a theory abotu what they called "dark matter".
this dark matter is suppost to be some sort of counter part to gravity.
as einstein has once discrbes as his bigges failure in his time, the cosmic constant as he named it (wich was something like that there is a constand force of matter that keeps the cosmic static) seemed to be right after all.
what this has to do with ne thing i have no idea
just thought it might sund intelligent.
and oh yeah i also think this dark matter is what keeps us stikking to the planet.......
hope it makes ne sence, problably but what the hell it sounds kewl
