einstein was a clever guy but I assure you this is impossible in practicality. the speed of light is fast in our everyday lives but it is painfully slow on the length scales of the universe. there is...

This is totally not relativity. One of the two postulates, ie. underlying assumptions, is that the speed of light is exactly the same when measured by anyone. Relativity states that there is no...

entropy is a macroscopic physical quantity, eg a house or a star can have an entropy. we relate this to the quantum mechanical system state occupation via statistical mechanics. the natural logarithm...

you would NOT end up where you started for one reason- the universe expands at a faster speed than our theoretical space travel maximum speed, so you'd never traverse the entire space, whatever the...

big bang theory makes no assertions about t < 0,- if there was nothing and then something that would violate causality, so Im loosely confident that there was probably something in some shape or form...

Also just adding that inflation is still not in any way agreed upon in the scientific community, there are problems with it- such as, what cased the inflation? Roger penrose worked with Hawking to...

I think this is a great question.. If I were to ask one question about dark matter it would now be this one! Im not sure how it fits into general relativity. In the cosmology I do at the moment,...

density parameter is about 1, but 0.7 of that is due to thecosmological constant so instead of a heat death, we'll all be torn apart.

As for dark energy- this is a total unknown, but the hard truth is there are seriously genuine observations of our universe that suggest this stuff exists- whatever it is.

electroweak symmetry breaking is at 100 Gev right where you have W and Z boson mass/energies. at the inflationary period 10^-34 seconds the energies are theoretically 10^16 GeV which is grand...
