the one dislike was a guy who doesn't speak physics =P

hi there,.. im a psychic.. ive watch your video.. i can help you explain to interpret, about that subject.. you can e-mail me t asti7natividadf@yahoo.com...

I can't even begin to imagine a shape which has no centre, so what shape do you think the Universe is ?
Why do you think that Redshift is only caused by movement (especially when this movement has not been verified by any other means) ? Aren't you aware of the several 'tired light' mechanisms which have been published ?

Direction stops being a factor when measuring galaxies moving away from us, because the universe isotropic. There is no center, therefore the direction isn't interesting - yes all galaxies move away from us, but all galaxies also move away from Andromeda (except that we're heading straight for it).
You can actually see for yourself, through redshift, that the universe is expanding. Distant light goes toward the red end of the spectrum. Why? Because of the expansion of the universe.

are you trying to beat the "fast talking" world record? ;)

hahaha cosmic halitosis

I would have no problem with space expanding if anyone can demonstrate that space is a thing/object/material that can (stretch or) expand - and do this in a lab.
The definition of velocity is: change in distance (displacement) divided by change in time (period) - and velocity is a vector so the direction is important. If a galaxy is detected moving away from us then it is unscientific to redefine this as anything other than a velocity just to suit your (cosmologist's) theory.

@1thermon what's the problem with space expanding? And what does "violation of velocity definition" mean?

A constant that's changing over time? Well that's a paradox.

Golly... Sounds like an important number. Where do you keep it? I think I'd keep it in a cabinet. Don't be losing it now!
