We should not think of the universe in the same way. The universe doesn't have an outer perimeter, and nothing exists outside it, because there isn't an outside. As an analogy, consider the shape of our galaxy, the Milky Way. We can infer that it is a spiral based on maps of th...
distances,however,billions of other galaxies are scattered.These galaxies are of many shapes and sizes.The Milky Way Galaxy is shaped like a spiral(螺旋型)disk.Other galaxies have been found to be shaped like spirals,too.In addition,still other galaxies are elliptical or irregular in shape. ...
We have galaxies of different shapes. The most common shape is the elliptical galaxy, then we have the disk shaped galaxy called the spiral galaxy and finally the galaxies with an unusual or irregular shape called irregular galaxies. Galaxies which consist of less than a billion stars are consid...

It is common to discretize this conjecture in terms of small scale . Roughly speaking, the conjecture then asserts that if one has a family of tubes of cardinality , and pointing in a -separated set of directions, then the union of these tubes should have volume . Here we shall be a ...
