Yes of course ... Instead of the usual Israel bashing, and jumping to conclusions about their 'fascist' motives, maybe we should investigate ALL the possibilities. It's not like Hamas. the PLO, or Authority, or any other group has shied away from using people as pawns in their terrorist agenda. They have fired rockets from hospitals, schools, and, it seems to me, the biggest bang for your buck would be if they forced Israel to retaliate against a building housing news organizations. What better way to shame the Israelis and let the world know of their despicable actions. But let's not investigate whether rockets were actually fired from the AP building, let's just blame Israel as always; it's fashionable isn't it ?

'Batwoman' is very well known for her work in tranmissible coronavirus deseases of bat origin. Her name is Shi Zhengli. Shi Zhengli - Wikipedia A Google search of 'Bat scientist of Wuhan' returns 3 620 000 results. Far from ambiguous, CharonY, but I do agree with your assessment of R Paul's character.

This is what happens when you take YouTube videos too seriously ... You are conflating the 2D analog of 4D space-time, the rubber sheet, and assuming it is stretched around a huge mass ( the Earth, in the analog ) composed of exotic or dark matter ( exotic matter makes no sense ), such that the dimples in the analog sheet are reproduced in space-time. While this might reproduce some of the effects of gravity, it most certainly cannot reproduce some of the more exotic effects of GR. ( lets see you try to model a Black Hole from the ubber sheet analogy ) Further, what is the separation between the exotic/dark matter core, and the reduced dimensionality universe of 'real' matter ? Can matter ( and properties ) be exchanged through this separation ? ( exotic matter has negative energy, and 'repels' gravitationally; that is why it doesn't make sense ) I think you have taken the 'rubber sheet' analogy waaaay too far ...

Actually Beecee, I would say ( and agree with K Thorne ) they provide a possible mechanism, but there are laws of Physics that could very well prevent the mechanism from working. And, as the mechanism involves the relativistic motion and return of one end of the wormhole, you could not go back in time to a point before the relativistic journey began.

If you invested as much time trying to understand accepted science as you have wasted on this useless conjecture, you would be that much further ahead, and have a good base to build on. Space-time has no associated 'fabric', nor can it be pushed or pulled. Stop wasting your time.

I'm not convinced of that either. A Martian day is similar to an Earth day, which might not be enough time to freeze or liquify completely, leading to a perpetually liquid or ice ring around the planet. Or possibly a state of 'slush' as a large buffer between the ice and water sections. I find it interesting as an idealized mental exercise, but the 'realities' which Studiot mentions, make it impractical, if not impossible.

Typically, an engineer 'applies' ( usually known )science, while a scientist 'derives' it.

So, using water which expands on freezing, you expect a higher pressure on th day-to-night freezing interface, and a lower pressure on the night-to-day thawing interface, leading to a pressure gradient, and a net flow of water, from which you hope to generate power. Obviously if a liquid other than water was used, that doesn't change density on freezing, you would have no pressure gradient, and no flow. The frozen section would just move around following the night-side. But what if you had any other liquid that contracts on freezing. Your analysis would then indicate a reverse pressure gradient, and a flow in the opposing direction ?

Does it really ? That is the reason that the exact opposite is true. All Black Holes conserve mass, charge and angular momentum in the Event Horizon, so that when a BH acquires any charge, more of the same charge in the accretion disk is 'repulsed by 36 orders of magnitude than would be attracted by equivalent gravity. Dissimilar charges, however, are attracted, and tend to neutralize any pre-existing charge. I would think a charged BH would be almost impossible to find. ( similarly I would expect to find few, if any, non-rotating BHs, as the collapse would increase even the slightest rotation immensely ) You make a lot of statements about how an accretion disk around massive BHs is not capable of generating the intense radiation seen from Quasars, yet you provide no numbers or reasoning for your assertions, Incidentally, spiral galaxies, like ours are generally NOT active; much younger types usually are, and that is why Quasars are seen at considerable distances ( and far back in time ). As for the rest of your post, maybe you could cut it down, and present a few items at a time, so that we can discuss each, and present counter-arguments, without having to write a 'book'.

You weren't a 'geek' when you were James Bond ... ( apologies to new members; you had to be there )

Take any badly poured concrete slab, that doesn't properly drain water underneath. It experiences cyclic up/down movement yearly. It heaves up during the winter when the water trapped underneath freezes, and returns back down during the thaw and settling of summer. The cycle is only 1 per year, but with proper gearing you could probably get better 😀 .

My apologies if I came across as hostile. I was simply trying to stress the risks you pose to those you come in contact with, or care about, if you don't get vaccinated. In your commendable quest for more information, trying to find out how your decisions affect only you, and not everyone else around you, might give people a valid reason for thinking you are selfish. Thanks for the info, CharonY. I remember reading about it much more often about a year ago, where people who contracted Covid had their blood turn to a jelly consistency. I haven't heard much about this symptom/effect lately..

In various circuits, the active 'ingredient' ( depending on the type of circuit, could be current, voltage signal, etc. ) can either follow itself ( one after the other ) down the same path, as in a serial circuit, or, it can split into two ( or more ) different paths, and re-join later, as it does in a parallel circuit.

Bezos and Musk graduated from Princeton and MIT respectively, as engineers. Gates, dropped out of Harvard after two years, and most of his 'degrees' are honorary. That is not a put-down of their intelligence, as all three are brilliant. ( Gates, the drop-uot, scored 1590 out of 1600 on his SATs. )

Virtual particles are parts of a mathematical model which describes/predicts quite a few observations and measurements. Without virtual particles the model would fail. Does that make them 'real' ?

Have you no family ? Have you no social life ? Is there no-one you wish to protect from getting infected by you ? If so, you have bigger problems than Covid-19 or the vaccines. One thing I have never understood ... They publish the numbers of people ( out of millions ) who get blood clots from the vectorRNA vaccines, Astra-Zeneca and Johnson and Johnson, which have now gotten a bad name as 'second best',but no one has ever given numbers of how many people get blood clots from Covid-19. I would bet good money it is orders of magnitude higher.

reminds me of all the cover illustrations of the paperback sci-fi novels I used to read. That might be a market for your art.

If you read the .pdf you should have realized that 'wormholes-as-time-machines' don't work that way.

100 years is a very long time frame.

Closed timelike curves don't work that way, not even with stable ( ? ) wormholes. Take a look at these lecture notes from K Thorne ( he gets to wormhole time travel near the end ) II-121.pdf (caltech.edu)

I think anti-matter stars is jumping the gun. There are many other viable explanations.

LOL I just finally got a haircut the other day. Wanted to have cute hair for the nurses giving the vaccine. getting back to SpaceX, this is what happens when someone other than NASA ( or the Russians and ESA ) puts payloads into orbit. Huge Chinese rocket core falling ‘out of control’ back to Earth (msn.com) Do we want 20 tons or more, hurtling out of the sky in an uncontrolled re-entry ? I guess, if you cut corners and don't care about safety, you can put a payload into LEO very cheaply.

Nap's over, Stringy. ( and I'm back at work tomorrow evening; been napping for almost 2 1/2 weeks ) ... that leads stock brokers to jump out of 20th story windows, on particularly dark Mondays ( 1929, 1987, 2008, etc. )

I sncerely doubt that, Zap 🙂 . My apologies, that should be Stringy, not Zap. ( I don't think they are any smarter than you either, Zap )

depends on what you mean by 'free'. A Black Hole can supply energy, which might seem free, but it is at the expense of the BH's mass-energy, or size of EH.
