It has recently been found that the reason that humans have two less chromosomes than other great apes is due to a merging of two chromosomes into one in the past. So we have 23 pairs not 24 as in...
According to something I read by Brian Cox, the Higgs field condensed ( whatever that means ) out of the vacuum in the early universe, filling the void with Higgs particles. These particles interact...
When the Earths magnetic field reverses at some future date, will it just rotate or will it reduce to zero and increase to its new opposite new position? The difference is that the protection from...
How long would it take from the frame of reference of the crew to get to a star system 40 light years away at a constant 1g accelleration. Does time dilation make colonisation a real possibility or...
Recently the likelihood of Earth type planets has been shown to be higher than was expected. Relativistic effects mean that time dilation makes possible journeys of cosmic distances. For the...
Electric force charges on quarks are +2/3 and -1/3 for up and down variants. The charge on an electron is -1 Quarks balance in groups of 3 to give a net charge of +1 or zero in nuclei in atoms. The...

According to some variants of String Theory, we are living on a 4 dimensional membrane in a 10 dimensional bulk space. Gravity appears weak because it is the only force that leaks out of our membrane...
The size of the observable universe is bounded by the distance that light has had time to travel to us. An observer in the Andromeda Galaxy would have a slightly different observable universe to ours...
I am told that the force of gravity is caused by the warping of space/time by mass. This seems to be fundamentally different from the other 3 forces which are due to exchange of particles such as...
