how small we really are

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.

Cox's theory is that as intelligent beings we spread across our planet in an incredibly short time. Any alien civilization would have done the same thing but across the entire universe/galaxy and we would therefore have evidence of their existence. His conclusion is we have none so there are none and have never been any.

Brian Cox has reignited a scientific controversy over the likelihood of alien intelligence
HUMANS are probably the sole masters of the universe, because the evolutionary flukes that gave rise to us are highly unlikely ever to have happened on another planet, according to Professor Brian Cox.

He has stepped into one of science’s longest-lasting controversies: could intelligent life have evolved on any planet besides Earth? His conclusion: we are alone.

Cox’s reasoning derives largely from one observation — we have never seen any alien artefacts. He argues that, if any such intelligence had evolved, it would have spread itself or its space probes across the galaxy — and we have seen nothing.

Their absence, he argues, “suggests that there is only one advanced technological civilisation in this galaxy and there has only ever been one — and that’s us. We are unique.”

Cox, a particle physicist, cosmologist and former keyboard player in the pop group D:Ream, came out as a non-believer in the latest episod...
On further investigation I think Cox is a Fermi Paradox enthusiast

I watched the final episode last night. Fascinating. He seemed to be believe we're the only intelligent life. With his closing monologue i think he said if we are alone we have a duty to ensure our survival as a race. That it was an uncaring universe and we must think more scientifically as humans. I agreed with it all anyway, hard not to.

FOR LAST TIME: I think life is common in universe. We MAY be only civ. in Milky Way. There WILL be other civilisations in univ. #shutupnow

It's amazing how quickly you can turn a discussion on science into a thread all about your religion and how you dislike atheists.

I cannot believe how slow I've been on the uptake here. I thought you were arguing a position based on something Cox said because you believe it was misrepresented by people on the thread. I've only just worked out that you NEED somebody to try and say that humans are unique and the only intelligent life because yet again it fits into your religious view. We're arguing about science and you cannot join in in good faith because to do so would compromise your religious views. That's why we will never agree on these things. I'm arguing out of evidence and logic with no particular investment which way an issue falls whereas every issue has to fall on the same side as your book says.

If you cannot seperate your religious views from your scientific understanding of the Universe then you really should give threads like this a miss as you're only going to spark arguments and not debate. You do fine on philosophical issues but we're not talking philosophy here, we're talking about science and you interpret every single thing seemingly in the entire Universe through the lens of your religion. You're a fine example of why religious people are so annoying in this context.
In 1277, Etienne Tempier, the bishop of Paris, condemned the belief "that the First Cause cannot make many worlds." Religious thinkers across all faiths have discussed the possibility of extra-terrestial life for centuries. Although most theologies unsurprisingly elevate mankind there is no essential conflict, in fact I'd be delighted to find out what alien civilizations make of God if I had the opportunity. May I also say that many of my best friends are atheists.

As to your second point. Science is a wonderful thing and it's findings are not and never have been in competition with religious faith. (Organized religion is a different matter of course.) I'd go as far as to say that I cannot conceive of any scientific discovery that would not be compatible with an Almighty Loving Creator, if you can I'd be very pleased to discuss it in true Socratic fashion.

all that is that if real a deity is supposedly omnipotent and could make many worlds if needed.
and as per usual you start from a standpoint of something that is real but in reality have no idea if so.

I have a question for you George.

How could he possibly know this?

For something to happen in a "short time" there must be example of a non-short (i.e. long time). We can say that City went to the top of the leagues in a short time because we can compare to other teams who took longer than City and build up what we consider to be a normal speed in contrast to us. We can say that the development of the Sun took a long time compared to other stars in the Universe but only a short time compared to other hydrogen based yellow dwarfs in the area.
When you compare the length of times you always must have something to compare to otherwise it makes no sense as there's no universal measurement of "a long time". The dwarf is king in the land of the midgets and what have you.

He can't compare our speed of technological growth to anything else so he has no idea if we spread across the planet in a very short time or a very long time compared to other intelligent beings if they exist.

He also has that disease that some space lovers have where they presume that all intelligent life must somehow have conquered a bunch of other planets and be these great civilizations. There's nothing to suggest that that is true, perhaps they don't share our love of exploration and they are all sat round in villages in a single continent? Perhaps they have far off advanced technology that we cannot detect? Perhaps King Ziggy the Fourteenth decided that they shall install a radio filter around their planet because they are insular and scared? Perhaps they wiped themselves out in a nuclear explosion and only packets of the civilization remain?

We've had radio for about 120 years give or take. Our species has been on the planet for about 30,000 years and civilized into forms we'd recognise for about 6000-7000 years. Having radio for 120 of those 7000 years and then demanding that this is something any other alien life should have for them to be intelligent would be the height of arrogance.

This is sort of what I said to Mark before. Just because Cox is a particle physicist doesn't give him any authority in this area if his conclusions don't make any sense.

Obviously in the limited amount of the article that you ''read'', you failed to again see the difference between a GALAXY and a UNIVERSE.
Also your initial claim makes no sense and is not consistent with anything Brian Cox has said. At what point does the fact that humans spread across a planet quickly mean that an alien species would spread across a universe??
Intelligent life forms may still only have the technology to learn about their own solar system, much in the same way we do. We haven't even walked on another planet yet. So how can we expect other lifeforms to have travelled lightyears on a whim?
