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.

There is nothing broken about the model, so far. Measurement of the Hubble expansion constant has varied through the years ( E Hubble's original estimate was way too low ) simply because it needs to use 'markers' to judge distance. We are talking about huge distances where triangulation is useless, so astronomers look for 'standard candles', astronomical objects that have a specific brightness, and judge distance by comparing relative brightness. E Hubble originally used Cepheid variable stars, but this turned out to give wrong figures, and a more accurate estimate was obtained using type 1A supernovae. The latest estimates have been obtained using the CMB relic radiation, giving a result almost 10% lower, and, in the study described in the article, brightness of red giant stars, which reach uniform brightness, gives an in-between estimate. If you take error into consideration, all three are probably valid. edit This may give a clearer understanding Cosmic distance ladder - Wikipedia

Canada ? Because we're nice guys. And we're waaaay behind in our vaccination targets. ( just got my 1st Pfizer shot today; second scheduled for Aug 23 !!! )

But ... they seemed like a good idea at the time.

No, the EH is not a 'separator' for all rames. And there is no variance to the laws of physics on either side.

I sncerely doubt that, Zap 🙂 .

Not that I agree with, or like, IDNeon's posting style. Nor do I agree with many of his assertions. We most certainly will go to the Moon, and ( not anytime soon ) Mars. But the 50s and 60s were different times, after the 70s, beancounters made the decisions, and still do to this day. But some I do agree with. Last year was the first year Tesla ever made a profit, yet it is one of the most valuable companies in the world. SpaceX has no new technology, but NASA didn't have to pony-up development money for a new launcher ( to low Earth orbit ). I would not be surprised if SpaceX/E Musk is losing money with every launch. But hey, E Musk gets to make outlandish claims and gets publicity. And similarly to a 'cult', people lap it up. Does the CEO of GM, or the head of NASA, go on Saturday Night Live ? Do they make an announcement about having bought their strangely named kid a variety of bitcoin, which jumps in value several hundred percent in the next couple of days, due to their millions of Instagram followers ? Do they use their launching system to put a car into space ???? Of course not ! These are all E Musk publicity stunts. He's developing his cult of personalty. And of course he'll succeed, because we, as a socety, place popularity above all else. It's the same reason we buy a $1200 iPhones, and replace them yearly when the new model comes out, or buy a $2000 Macbook when a $600 Lenovo or Dell will do the same job, making Apple the most valuable company in the world.

If the wormhole allows for violation of spatial translation symmetry, that is, if the laws of physics distinguish between different points in space ( external and internal to the wormhole ), then conservation of momentum is not required.

I'm with Joigus on this one. I've been to Swtzerland; didn't like it much. I think I would prefer Spain.

Soooo Are you saying theis class doesn't have any problems, contrary to reported news? Are you saying they do, but so do the Americans, even though we're not talking about US ships ? Are you saying they had problems, didn't finish the 5th ship, and two are mothballed ( leaving 2 out of what was supposed to be 5 ), because the Soviet Union broke up 30 years ago ? And why are you using their break-up as an excuse ? Why did the Soviet Union break up ? Oh yeah ! They broke up because the 'arms race' required them to spend too much on weapons like the Kirov class, instead of feeding the people. Jesus, it's almost like you weren't alive when the Soviet Union collapsed !

Good way to confuse yourself and others. All information is limited to c , and, other than relic ( unchanging ) space-time curvature, cannot affect you any faster than the light reaching you. 'Actual' position is non-sensical, it is like saying "Where is it, now", and we know that there is no 'now' for everyone and every place.
