They looked to be flying at the same speed (I think it was around 30,000 mph), but being up in the sky we couldn't tell how far apart they were. Where do I find this information?

I heard that Betelgeuse has already exploded. (I know about the time difference) I just wonder if it is true. Are there other known stars that no longer exist? Or that have lost their luminocity?

He sums up why homology is a problem for the theory of evolution as follows:

What mechanism can it be that results in the production of homologous organs, the same 'patterns', in spite of their not being controlled by the same genes? I asked this question in 1938, and it has not been answered.

Although some 30 years have passed since de Beer wrote those words, they have still received no answer?

The discovery which really overthrew homology is that organs accepted as "homologous" are almost all controlled by very different genetic codes.

Is there a scientific response to this, that would gave support to theory of evolution?

First off let me say I have no intention of offending anyone by posting this, and I know it sounds awfully like Nazi propaganda (which it probably was at one point) but I know nothing about biology or genes so would like to hear an educated opinion.

My point is this; if we all evolved from dark-haired apes in to dark-skinned people living on what is now the continent of Africa, and then spread out across the globe, surely the white blond/ blue eyed people were the last to develop as their colouring would have taken the longest time to develop. So does this mean anything genetically?

As I have previously I am not racist, a facist, a Nazi or anything else of the sort but I am uneducated when it comes to matters of biology and the above argument does sort of make sense to someone with no knowledge of the subject, so I'd just like it cleared up by someone in the know.

I know nothing of science but have phrased this as PC as I could so please no comments about me being a Nazi.

So, if Earth is flat, as proven by Google Earth, how thick is it. You must take into account how deep the oceans and mines are. Think about it, let your mind go off at a tangent. Give me some really witty, droll and inspired answers. The best one gets a smartie!!!!
