Compared with Antares shown in the diagram, the largest known stars (UY Scuti or NML Cygni) are virtually twice the diameter!

Saw another vid similar to Your one Dave (Cant find it now) Love to see it again.
Started with planet Earth and zoomed in, way way past the atom (And its quite small) then zoomed out again right to the edge of our universe - It was a great vid, very hard to grasp the Scale...!!!

I think this may be it. Hold on to your hats, you are about to discover just how insignificant you are...

Cheers Dave - That was indeed the vid i meant, mind boggling (WE CANT BE ALONE IN ALL THAT, CAN WE)...?
Thanks for digging it out.

Cheers Dave - That was indeed the vid i meant, mind boggling ( WE CANT BE ALONE IN ALL THAT, CAN WE)...? Thanks for digging it out. I think that is highly unlikely bearing in mind that we don't even know the true extent of the universe as yet, we are merely making educated guesses (I'd even question that). It's also worth recalling these wise words: "The universe is not only weirder than we imagine, it is weirder than we can imagine..."
There are some very clever people working in all aspects of astronomy and astrophysics who are simply tearing away from the pack. I wonder how many people actually understand the niceties of it all (and we're not talking those who couldn't give a damn here, but members of the general population who are genuinely interested in the universe and its origins). I have a fairly decent grasp on the concepts but the maths and physics of it is way beyond my ken. As progress marches on the subject is likely to become increasingly inaccessible to the likes of myself and others thus creating a small but knowledgeable Superclass of people. Where that might lead is anybody's guess...

Most of the knowledge on the none observable universe is so theory dependant it aint worth taking seriously at the moment as it amounts to noting more than intellectual mathematical mind games .
life on earth is dependant on a series of flukes [correct distance from sun etc] it would be barmy to presume such exact conditions are replicated elsewhere .
All in all , a rational man , with no agenda can only believe this is indeed it .

But your argument presumes full knowledge of the entire universe and all its mechanisms. Do you know something we don't know Daniel? |

No it doesn't .

I realise this is a difficult concept to grasp for one of your ideology (there's enough to keep you busy here on our pale blue dot) but we simply do not know whether there are other civilisations out there. To deny the existence of other civilisations is as ill-informed as claiming they actually exist in this instance. I, for example, would not claim they exist nor have done so in the past, but considering the existence of the universe in itself might well be a fluke then anything is possible... (note my use of the word 'possible') |
