Exotic matter doesnt exist, similar to dark matter its just a name for something which we know has to be there for our theories to work, unfortunately however it isnt thus we invent a name for it just to make our current theories work, sometimes we find the missing matter, other times we find a new theory. Secondly there is no proof of wormholes existing either nor that it is possible to travel across them let alone travel across them safely, its again just a theory which has many flaws and assumptions, such as the need for parallel universes which may or may not exist.
Now as for astral projection I would recommend you check out the videos on this site, there are some really useful ones on the subject.
Wow, yakov that was such a flawed answer. We have more than enough proof of dark matter, wormholes, and parallel dimensions. Dark matter, without it being there the galaxies would fly apart and we wouldn't be alive. Wormholes, I need to brush up on those. Parallel dimensions were proven by the Large Hadron Collidor (sp?), when it was switched on it produced microscopic black holes that disappeared as soon as the appeared.

As soon as i see your degree in astrophysics i will believe that scientists decided to just say screw it lets make up something that is going to be the basis for most of the studies in that particular area of science.
Whilst I dont have an astrophysics degree I am studying it. Unfortunately we dont know anything about the vast majority of the universe because simply put we just cant see it. As I said dark matter is there according to calculation only, in practice we cannot find it, I think my English let me down slightly, I should have said as it stands exotic particles do not exist. As for parallel dimensions they are there to explain various aspects of astrophysics which can not currently be otherwise explained, the black holes temporarily created in a particle collision are created because the atoms within a moment create what is called a singularity which is an infinitely small area which has a relatively high mass thus giving a large gravitational pull however the strong force can not hold the two similarly charged particles within our gravitational field and thus instantly expels matter, which is fairly fortunate, this phenomena doesnt explain the existence of parallel universe only of the four forces. As for wormholes themselves they are, a rather ingenious and complex theory that I will admit I do not at present fully understand however it is currently still a theory that is more than possible however near impossible to prove without actually being within the event itself.
To travel astrally across the universe is possible. Also, physically creating a portal out of energy is totally possible (It would take a lot of practice)
