Metaphysics is the term for physics ideas that cant be tested so need to be in the realm of philosophy. as i said this is perhaps not metaphysics but i treat it like anything i will never fully understand such as politics or most things about life. i only worry about truly understanding molecular biology or the origins of life.James Lloydhttps://www.blogger.com/profile/08219295648051788360noreply@blogger.comtag:blogger.com,1999:blog-496263467300370264.post-1303057059507246422007-08-22T16:04:00.000+01:002007-08-22T16:04:00.000+01:00God that is confusing...

I guess the problem with this sort of area that I at least don't master, is the fact that I have no idea if statments like 'the universe i donut-shaped' can be compared to 'nucleotides can be A, T, C or G' or something of the kind 'Eating DNA can be dangerous for you'... We don't understand the maths, so I reckon that only much reading and discussions with sensible people who can actually understand it is the only way of having a sensible view of the subject?Cathttps://www.blogger.com/profile/08645968914831610862noreply@blogger.comtag:blogger.com,1999:blog-496263467300370264.post-47991518918517901932007-08-09T23:08:00.000+01:002007-08-09T23:08:00.000+01:00really good video. i agree it seems weired how peo...really good video. i agree it seems weired how people get funding for this but humans love to ask questions and explore, even if in the short term or not even the nearish long term these things wont help gain profit one day the understandings may. a lot of biological research perhaps has little immediate benefit but one day it may. the pure side of things may one day help the applied.James Lloydhttps://www.blogger.com/profile/08219295648051788360noreply@blogger.comtag:blogger.com,1999:blog-496263467300370264.post-84677854608491445182007-08-09T20:35:00.000+01:002007-08-09T20:35:00.000+01:00Lucy, I share your skepticism about the multiverse...Lucy, I share your skepticism about the multiverse theories but I think there is a whole lot that we cannot even begin to understand unless we know the mathematics behind it. I have no idea how anyone can say whether the universe is donut shaped or infinite, but if those people are out there saying things like that and haven't been locked up yet, they must have some sort of rational reason to believe so. I don't actually understand how people get funding for this sort of research since what they keep concluding is that their research basically does not concern anyone... quite bizarre.<BR/><BR/>Anyway, about the quantum thing, this one is a lot more tangible, and is not at all as nonsensical as it sounds.

I mean if you think of all the events that would have to happen, over millions of years exactly the same, and you could multiply all the probabilities together of that happening, I suppose technically it would be POSSIBLE (ie it wouldn't be a probability of 0), and in a universe of INFINITE possibilities, it would have to exist... so the theory works, yet I still don't see it as likely.<BR/><BR/>I guess the problem I have with it is that the theory only holds GIVEN that the universe is infinite, which is far from a given. These theories are making predictions providing that other uncertain things are true; I think that people would need to prove the underlying principles (though don't ask me how you'd prove the universe was infinite) before they can start making these kind of theories.<BR/><BR/>Also I read up on the cat thing and I just don't see what's going on with that. So if I checked on this cat and found him dead then that's that, but if instead I'd decided not to look in this box, he'd be sat there, both dead AND alive?! HOW does this kind of theory make ANY sense, something cannot exist in two mutually exclusive states at once!Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-496263467300370264.post-87562615197872812752007-08-09T11:46:00.000+01:002007-08-09T11:46:00.000+01:00thank you. good question can you travel between an...thank you. good question can you travel between any of these. if you could travel far greater than the speed of light which people dream of but many think is impossible we could visit other level I universes. these are in our space time and are simply far away. assuming the universe is infinite (which may be a big leap) it is going on a road trip to somewhere else but the country is so large the place starts to repeat themselves. like is england was infinitely large you would keep driving and find another york almost exactly the same as ours with the same people. it is that idea as level I. problem is space is so large and them times that by infinitely and you wouldn't be able to know where you are going or have a map. so traveling to one may be possible but finding one to head for i think is even more difficult. <BR/><BR/>i think level II would be out of our grasp becasue each level I multiverse inside it is somehow infinite but if you break out of it you still have massive rapidly expanding space to travel. <BR/><BR/>for level III they are somewhere but where? do they exist all around us as invisible small universes. i really dont know how you could travel to one of them. first step would be finding them if they exist. <BR/><BR/>hope that tries to answer your question. any more please.James Lloydhttps://www.blogger.com/profile/08219295648051788360noreply@blogger.comtag:blogger.com,1999:blog-496263467300370264.post-86810784212079924252007-08-08T20:31:00.000+01:002007-08-08T20:31:00.000+01:00Lucy has to read this post, I think she will have ...Lucy has to read this post, I think she will have some very interesting views on it.<BR/><BR/>I like the fact that science fiction is turning into scientific theory, it makes star trek seem like slightly less of a waste of time. I don't think that it is very easy to explain most of the things in your post without using mathematics but you have done pretty well!<BR/><BR/>Is there ANY way to travel between multiverses of whatever level? I am talking about things like black holes because the classical science fiction idea is that you can travel vast distances within our spacetime (which according to the things you explain here includes up to Level III multiverses) using black holes, so is this based on any actual science or is it pure fiction?Menelaos Symeonideshttps://www.blogger.com/profile/05361581879935604330noreply@blogger.com
