For dimensional analysis, the universe can be considered the visible picture from earth. The dimensions of the universe are deduced from Hubble's constant, a factor related to the rate at which the universe is expanding. The traditional methods of determining this constant, which is the ...

than we could have imagined, where 'dark matter' reigns, space warps and wiggles through eleven dimensions, minute particles dance, fizz and teleport across vast distances, everything is made of vibrating strings and, like an ant on a lily-pad, we may be floating on a sliver of spacetime....
Einstein and the Shape of the Universe Thanks togeneral relativity, we know we exist in four dimensions. There are the three that you move through space in (left/right, up/down, back/forward). Then there is also time. Just as a caveat, we don’t really control our movement through tim...
The Universe - 150,000,000,000 light years <This is the rough estimate of the size of the universe but it can be many times larger than the above-mentioned dimensions. Thank YouDr. V. Shashikanth#148856 25 Feb 2018 09:36 Neeraj 123 Points: 0 deleted #148998 06 Mar 2018 22:00 ...
And here Jack Vance's richness of style serves to best advantage, creating gothic creatures that reverberate with the mythic dimensions of the Brothers Grimm, but which have the solidity, believability, and even upon occasion the psychological depth of well-realized science fiction. A palpable aura...
that inside the sphere and that outside. But that is only because we are embedding the two-dimensional spherical surface into a space of one higher dimension. If we restrict ourselves to two dimensions, the surface of the sphere is all there is. There is no edge, no inside, no outside...
In terms of itsshape, spacetime may exist in one of three possible configurations – positively-curved, negatively-curved and flat. These possibilities are based on the existence of at least four dimensions of space-time (an x-coordinate, a y-coordinate, a z-coordinate, and time), and depen...
