I am in a forum where there are two EU crackpot theorists that insist on the universe being infinite and static. Since the universe is 98.6% plasma; I asked them if plasma has mass. I am not a physicist but I know that a static universe cannot be if this plasma has mass as this would cause the...

I have heard of Flatland and seen many analogies regarding a 2 dimensional world but, can such exist? Considering that even subatomic particles move in 3 dimensions then am I to assume that a 2 dimensional world is an impossibility? Even a line is 3 dimensional for if a line were only 1...

I was wondering at what temperature would Titan's atmospheric particles reach escape velocity? Since Titan lacks the mass to hold onto its present atmosphere then would I be wrong to conclude that what holds such a thick atmosphere is the extremely low temperatures found on Titan?

This may sound out of topic but if the universe is expanding then how are some galaxies on a collision course with each other? Should they not all be receding from each other?

There are inherent problems with rotating space ships; that induce artificial gravity through centrifugal force. The most important of them is balance. If a person were to walk on the perimeter where the artificial gravity is strongest then his shifting mass will cause one side of the ship...

Assuming that a string is the size of 1 plank and thus the smallest possible entity. Also that it is not comprised of smaller particles then would it not be infinitely rigid? If so then how can it vibrate?

Thank you. Such wondrous things await us on the path to erudition!

This may seem like a stupid question but I am asking in curiosity: If the boundary where we can see no further of our universe is the starting point of the farthest photon that has reached us then is it possible that the universe is infinite but our visible universe is not the entire universe...

Theoretically; As any mass approaching the core of a black hole, then would the tidal force difference effect the quantum level and rip apart matter? Also at the very centre of a black hole would gravity cease to exert its force since in any direction the "pull" would be equal?

The point of the matter is "feasibility". Is or will it be feasible given the required energy and technology to achieve spacetime warping for travel? If the numbers add up and such technology although unattainable at present should be available in the future then obviously it will be...

I chanced upon this article in the Huffington Post and would like to ask if anyone is familiar with this work? Is this even feasible? http://www.huffingtonpost.com/2012/09/17/warp-drive-star-trek-feasible_n_1890679.html

A very interesting read indeed. Thanks!

Thank you all for the information. I will check it out. Lastly I really would appreciate it if phrases such as "its Nonsense" be kept out of my posts as they offer nothing and not forgetting that science requires us to be not only inquisitive but also sceptical too! Thanks guys!

I will accept that is is nonsense since you say so and I have no reason to doubt you. I gather that contemporary understanding of Black holes gives us the ability to dismiss some hypotheses without hesitation?
