Even if we don't have a precise idea of exactly what took place at the beginning, we can at least see that the origin of the universe from nothing ne….
Supposing we knew that up there is some alien civilization and it's sending radio signals our way we should not tell the public where that is. We cou….
Cancer is such a ruthless adversary because it behaves as if it has its own fiendishly cunning agenda..
An argument often given for why Earth couldn't host another form of life is that once the life we know became established, it would have eliminated a….
We know that within the solar system is very unlikely there will be anything more advanced than microbial life, but if we think outside the solar sys….
A permanent base on Mars would have a number of advantages beyond being a bonanza for planetary science and geology. If, as some evidence suggests, e….
