So let me get this straight: maybe theadvancedapes can clarify if I'm wrong: Hawking (or at least this video) is suggesting that black holes are developing as we speak and that eventually one of them will explode causing another big bang. Is that it?
Black holes are everywhere. There is a supermassive black holes at the center of every galaxy and there are over ~100 billion galaxies in the observable universe. There are also millions (if not billions) of other black holes that are the product of supernova explosions of very large stars (I'm pretty sure at least 10 times the size of our parent star). Black holes won't explode to create a new universe in our universe. But they may be birthing new universes in different realities. That is a theory that the opposite of a black hole is a "white hole" and that what we observed with the Big Bang is a white hole produced from a black hole in another reality.Hawking (or at least this video) is suggesting that black holes are developing as we speak and that eventually one of them will explode causing another big bang.
Good, I'm glad that's cleared up. Would it be correct to imagine that OUR black hole -- the one that exploded into our galaxy -- was formed over billions of years prior to our big bang from other universes collapsing into it?
Just checking. A god is so much easier to imagine than an eternity of collapsing and exploding holes - or is it? We need that global brain soon.
OUR supermassive black hole at the center of the Milky Way formed as a consequences of galaxy formation, not the other way around. The first stars were gargantuan. Much larger with far shorter lives than do stars in the universe today. They formed massive black holes after their collapse. In the Milky Way, as in all other galaxies, this resulted in a large gravitational center around which all other "nearby" matter could coalesce. So a black hole didn't explode into our galaxy. Rather, aggregations of large stars in a proto-galaxy that would become the Milky Way, resulted in a supermassive black hole that would lead to the further growth of the galaxy. And nothing in our universe was formed before the Big Bang. All matter was created during the first microseconds of the emergence of space and time. EDIT: And we definitely need a Global Brain. Speaking of... I'm off today! Brussels here I come!Would it be correct to imagine that OUR black hole -- the one that exploded into our galaxy -- was formed over billions of years prior to our big bang from other universes collapsing into it?
I'm presenting at the Global Brain Institute October 4th! Then I'll be in Brussels until the 7th and England until the 12th. If my presentation goes well I'm hoping to do my Ph.D. there in 2014. So fingers crossed! My potential supervisor just sent me a working paper titled "Promises and Perils on the Road to Omnipotent Global Intelligence" for a publication in "Brink of Singularity". Just surreal...
It does sound to me like that is what the video is suggesting. I'll also await a scientists reply.But let’s go with optimism and hope that, rather than exercises in reductionism, formats like this are, as Neil deGrasse Tyson said of the soundbite, triggers for interest which “set a learning path into motion that becomes self-driven.” In other words, let’s hope this gets more people to read A Brief History of Time, one of these seven timeless reads about time.
Perhaps it's time that you read a Brief History of Time? It is a book that has been on my reading list for 10 years and somehow always manages to stay there.Hawking (or at least this video) is suggesting that more black holes are developing as we speak that will one day explode causing another big bang?
It's not unreadable. It's that people aren't interested in reading it; they're interested in wanting to read it. I read it many years ago, and it covers topics that are pretty deep in a pretty superficial way. You aren't going to come away with a great understanding of how the universe operates (and some of it you won't understand), but you will come away with a sense that you are more informed about what you are seeing when you look up at the stars.
