Is it possible to walk through a wall?

[Mehmani]

You could go a lot further than that. What is a wall? Why do we define certain objects as "walls"? Do we really exist or are we just the dream of some super-elephant from another universe? More importantly, how do magnets really work?

Aside from above trollpost, I must note that if an atom was the side of a football pitch, the mass of the nucleus/protons/neutrons would be less than the mass of the dot in the centre circle. <99% of an atom is nothing. But according to Physics, "nothing" doesn't exist.

Physics discussion.

Metaphorically speaking, is it scientifically possible for a human body to walk through a wall. More importantly, does that wall actually exist or is it only there because the human eye perceives it to be?

There is also a theory that for every action we do, an alternate universe is created where we did not take that action, but another one. I am currently creating a lot of alternate universes according this theory. Discuss this too.

Also discuss the fact that light acts completely differently when we observe it as to when we do not. This is very interesting as it could mean that the world we live it is not as we think it is.

well in the comixs with the flash flash was able go though walls by being able to vibrate his molcules really really fast (if vibrating your molcules really really fast indeed give that effect is it possible ???)

this idea was used in a old futurama episode

so (my example) in a alternative universe they did not kill osama bin laden there fore in that alternate universe he still running around causing problems (this seem posible even very possible of there being alternative universes out there)

what are your comments on what ive said ???

No.

Infinity is endless, therefore unobtainable. It would be entirely impossible to put your hand to a wall for an infinite amount of time and transfer atoms with the wall. The definition of a wall is extremely simple. A wide, sturdy structure that is capable of and used to block off, hold up, or defend/protect something. There is no substance in the that can fullfill those conditions and at the same time be permeable by other atoms. Walls out of pudding? Won't be sturdy, and will mostly be formless. Water? Once again, formless.

Infinity is an idea, not an actual achievable status. The only thing that is actually infinite that I can think of off the top of my head is the Universe, at least until the Big Rip/Big Freeze/Big Crunch/Whatever other ideas I'm forgetting.
