i.e. Overlapping dimensions a multiverse..(Our Earth existing in Different Universes Like in the movie 'The ONE')
The Supercollider project which will be carried out in 2009 may prove this or dissaprove it. What do you think and why?

is methane heavier or lighter than air? is it still gas at room tempurature? can you fill a normal balloon with it, and if so, what would would be the range of damage of lighting it on fire (with a fuse of course)

I don't know why some have a positive and sometimes the other is a negative correlation. Help please!

I'm doing maths and I'm currently doing correlations and I have two sets of data. One is Average Rainfall and the other Highest Temperature (C). Im confused and don't know which one is the dependant and independant variable. Can you please help? And a reason why that it is considered that?

Thanks :)

More diffusion in liquids than solids due to two factors.
1.greater intermolecular distances 2.great random motion.
when water freezes to give ice the intermolecular distances increases batween water molecules but the diffusion is still less than liquids why?
Some might think that diffusion only depends on random motion of molecules not inter molecular distances how do they justify their answer?

and
at STP distance between the melecules of an ideal gas is three hundered times greater than its diameter.(how its possible)
suppose diameter of h2 melecule is 2nm and two melecules are at a distance of 600nm.And diameter of CO melecule is 4nm(or take any other molecule larger in size than that of h2)and the distance between its two melecules will be 1200nm
so two melecules at STP are not occupying same volume.
if they have to occupy the same volume then CO molecules would have to come closer.
and if they come closer then distance between them will be not 300 times greater than their diameter.
if m wrong then how?
