youtube for the day/ Project Universe - Episode about the Big Bang

I remember finding this Universe: the Infinit Frontier.  They price this video series at five hundred dollars.  I just found this series; it's better and you can't get your hands on it in dvd form.  Honestly, I feel like I've confused these two video series.  I just found it and need to rewatch it to perhaps make more comments.  It is of course out of date(being made in 1978); but, it does mention Stephen Hawkings exploding black holes theory; it doesn't mention Alan Guth's inflationary cosmology(confirmed by the Cobe satellite . . . mentioned by Steven Weinberg in his "First three minutes" by the way . . . and later to more detail by later satellites).

But, this video series seems to me to convey the intellectual excitement better than most science videos.  

I think I can take advantage of this to point out something else somewhat related.  It's related in the sense that people often feel that simple mathematics(like number theory . . . which has been taken to such a level as to be inaccessable to most peoples minds) and science will never have practical applications.  Well, this application may be far off . . . even for a mature nanotechnological and quantum computer future!  Well, I don't know; i think it could be compared to the manhatten project or Apollo program for a nanomanufacturing, a.i.(made possible, probably, in a mature nanotechnological future), and quantum computing future! 

It is a recent (actually first breakthroughs appear to be in the 1990s mostly; of course, there the einstein rosen bridge of the 1930s) theoretical exciting possibility.  I'll go ahead and give a little bit of a abstract about it,


Making Stargates: The Physics of Traversable Absurdly Benign Wormholes

Extremely short throat “absurdly benign” wormholes enabling near instantaneous travel to arbitrarily remote locations in both space and time – stargates – have long been a staple of science fiction. The physical requirements for the production of such devices were worked out by Morris and Thorne in 1988. They approached the issue of rapid spacetime transport by asking the question: what constraints do the laws of physics as we know them place on an “arbitrarily advanced culture” (AAC)? Their answer – a Jupiter mass of negative restmass matter in a structure a few tens of meters in size – seems to have rendered such things beyond the realm of the believably achievable. This might be taken as justification for abandoning further serious exploration of the physics of stargates. If such an investigation is pursued, however, one way to do so is to invert Morris and Thorne's question and ask: if “arbitrarily advanced aliens” (AAAs) have actually made stargates, what must be true of the laws of physics for them to have done so? Elementary arithmetic reveals that stargates would have an “exotic” density of on the order of 1022 gm/cm3, that is, orders of magnitude higher than nuclear density. Not only does one have to achieve this stupendous density of negative mass matter, it must be done, presumably, only with the application of “low” energy electromagnetic fields. We examine this problem, finding that a plausible solution does not depend on the laws of quantum gravity, as some have proposed. Rather, the solution depends on understanding the nature of electrons in terms of a semi-classical extension of the exact, general relativistic electron model of Arnowitt, Deser, and Misner (ADM), and Mach's Principle."

Yes, a wormhole.  I don't think this abstract gives details about negative matter; but, i recall a paper shown to me at now obsolete messageboards showing that the cassimir affect could supply such negative matter.  The cassimir affect has been experimentally confirmed back in the later 1970s I do believe.  the cassimir affect has to do with a quantum attractive force between two plates(on a small almost molecular scale; some say this could pose problems for nanomachines); the way it works is that the plates make for less quantum wave states in between the two plates than all the quantum states bubbling out of the vacuum(this is a quantum electrodynamics thing; when Paul Dirac combined special relativity with the quantum mechanics of Shroedinger back in the 1930s, one major prediction of his generalized quantum mechanics was that the vacuum has particles coming into and out of existence so long as it all happens within the confines of the heisenberg principle; this is also how the quantum forces work; they exchange particles that come in and out of existence of the vacuum) outside of the plates; so, there's a greater outside pressure than in between the plates; this is the cassimir affect.   It could allow us to make wormholes happen(perhaps in the 22nd or 23rd centuries . . . if we survive a nanotechnological future). 

I should say I saw that I could post this wormhole stuff to post in relation to cosmology(and post these great science videos only available through youtube right now!) because black holes have to do with quantum gravity, and so does cosmology.  High density objects like studied in the frontiers of science today may allow us to make wormholes in perhaps comparatively near future!
