BradHorse Posted June 10, 2013 Share Posted June 10, 2013 Ultimately there will always be something left unexplained, whether it's why there is a universe, why there are fields of potentiality or why there is a god. The ultimate question of why stuff exists is something philosophers and theologians can bother each other about it if they want, but it's not a question for scientific debate. That's fair enough. Not a lot of point in raising an unanswerable question, but it's just the feeling I'm always left with when read about the start of the universe. 0 Quote Link to comment Share on other sites More sharing options...
RealMaroon Posted June 10, 2013 Share Posted June 10, 2013 I think in the next 50-100 years we will eventually reach an impassable stage where we can go no further. We will eventually reach our limitation as we exaust our resources and get to stage where we can no longer conduct these long reach studies. 0 Quote Link to comment Share on other sites More sharing options...
grumswall Posted June 10, 2013 Share Posted June 10, 2013 We as a race, despite understanding a fair bit, are imo not intelligent enough to ever understand much of what happens in the universe and we most likely never will be. 0 Quote Link to comment Share on other sites More sharing options...
Confidemus Posted June 11, 2013 Author Share Posted June 11, 2013 We as a race, despite understanding a fair bit, are imo not intelligent enough to ever understand much of what happens in the universe and we most likely never will be. It's a distinct likelihood that a lot of what happens in the Universe is beyond our understanding. We base much of what we know on things like the laws of thermodynamics, Einsteins theory of relativity etc. But what if, somewhere in the Universe, life exists that isn't carbon based and doesn't need water? What if there's a place where gravity has no effect and entropy doesn't exist. We're only taking what we know and making best guesses Another possibility for how the Universe started, and how it might end is the Big Crunch. In this, the Universe will expand to a finite point before contracting back in on itsself and either ending with everything in existence squashed into a singularity or causing another Big Bang. Could it be that the Univese has been big banging and big crunching forever? https://en.wikipedia.org/wiki/Big_Crunch 0 Quote Link to comment Share on other sites More sharing options...

cowboy Posted June 11, 2013 Share Posted June 11, 2013 how do garden peas know where to grab something? there I was last night, putting strings across between the poles, and the wee buggers were litteraly grabbing the string with their wee creepy feeler things, right in front of my very eyes. was very impressive. tomatoes on the other hand, made no attempt to hold on to their canes, and had to be tied, lazy b*****ds 0 Quote Link to comment Share on other sites More sharing options...
JustOneCornetto Posted June 11, 2013 Share Posted June 11, 2013 Just been reading about the theoretical Vacuum Metastability Event and I confess it's way over my head but how much credibility does this have in the scientific world? If it eventually did happen would the Universe collapse into a massive Black Hole and the whole process start again with another Big Bang? 0 Quote Link to comment Share on other sites More sharing options...
Confidemus Posted June 11, 2013 Author Share Posted June 11, 2013 (edited) Just been reading about the theoretical Vacuum Metastability Event and I confess it's way over my head but how much credibility does this have in the scientific world? If it eventually did happen would the Universe collapse into a massive Black Hole and the whole process start again with another Big Bang? If this did happen and the false vacuum became unstable and dropped energy, the whole thing would happen at the speed of light, and we'd know f**k all about it. It would be rather shite if it happened, though.

Confidemus Posted June 12, 2013 Author Share Posted June 12, 2013 Morning fellow space buffs! How about some large numbers to wrap your head around? How about what's actually in the observable universe, which is, for those who aren't sure, all the matter that is visible from present day Earth, as it's light has had time to reach us since the big bang. In the observable universe, there's estimated to be: 10 million Superclusters. (Large groups of smaller galaxy clusters) 25 billion Galaxy groups. Galaxy groups typically contain no more than 50 galaxies. 350 billion Large galaxies. 7 trillion Dwarf galaxies, which are small galaxies containing up to a few billion stars. 30 billion trillion (3x10²²) stars Quite a lot then. 0 Quote Link to comment Share on other sites More sharing options...
Boghead ranter Posted June 12, 2013 Share Posted June 12, 2013 If everything in the universe was all stuck together, now much volume would it take up? 0 Quote Link to comment Share on other sites More sharing options...
Confidemus Posted June 12, 2013 Author Share Posted June 12, 2013 If everything in the universe was all stuck together, now much volume would it take up? Given that the universal is always expanding, and it's really sparsely populated with matter, this is almost impossible to even take a stab at, but a good estimate I've seen is: 3.35 × 1054 kilograms Which is a lot. As for the volume it would take up, even harder to say. For example, Saturn is so lacking in density, it could theoretically float in water, whereas a neutron star is so dense a teaspoon of it would weigh as much as a mountain. 0 Quote Link to comment Share on other sites More sharing options...
RawB93 Posted June 12, 2013 Share Posted June 12, 2013 It's really upsetting I'll never be able to travel through space. Can't think of anywhere else I'd feel more at home. 100% nature, left untouched. Long may it remain that way. 0 Quote Link to comment Share on other sites More sharing options...

And for the bits that have nature, you realise how dangerous they are? 7,000 mph winds, gravity that would squash to 1 millionth your current size, magnetism that would literally rip you apart, radiation that would kill you in under a second, temperatures that would melt you instantly. Plus there's no clunge in space. 0 Quote Link to comment Share on other sites More sharing options...

The universe will only end because he'll literally have shagged it to death. 0 Quote Link to comment Share on other sites More sharing options...
