blueish swede said:First, to be clear to everyone where my agenda lies - I am a radical athiest.
Second, Brian Cox is a yonner.
Third, his lack of undestanding of some quite simpe things are pretty remarkable - a good example is the rules of tackling in football which in Cox's case aproach those of Paul Scholes. I have empirical evidence of this. Any decent BM cold case team could probably find evidence on the 5-a-side pitches under the Mancunian Way.
He does however have a very good grasp of astrophysics and cosmology. Particle physics and astrophysics are fundamentally the same subject viewed from two different perspectives.
All that being said we, the people alive on earth today, are alone in the universe* and we will die knowing we are alone in the universe. Anything beyond that is postulation and as useful as a discussion on angels balancing on the head of a pin.
*If we are alone as intelligent life in the galaxy we are to all intents and purposes alone in the universe.
A couple of things here:
Whilst astrophysics and particle physics are similar, thye aren't the same thing. Astrobiology which this would fall under is on a different planet if you'll pardon the pun.
Secondly, the existence of other intelligent beings does not rely on our knowledge of them. You can't just say we're alone in the Universe and that's it because we have no data at all to judge anything off of.
