100% of the surface of the Earth is covered by a miles thick atmosphere. Does the Earth really belong to the fish ? Or to the birds ? That is one of the silliest arguments I've heard in a long time. And what kind of 'new age' jargon is 'balance' ?

I have often found the opposite to be true. A cotton T-shirt will 'smell' after a workout. A synthetc workout shirt will not.

Where, and how, are you 'stuck' ?

I'd have to look for the source, but I thought that had already been verified for gravity 'leaking' into compactified' extra spatial dimensions ( at small scales ). The above ( always ) excellent PBS video provides Gravitational wave evidence for the absence of extra large scale spatial dimensions.

Yes, it is resonance at a particular frequency, in the case of a glass or window, shattered vocally. In the case of a sonic boom ( from a supersonic plane ), it is a very steep pressure gradient that packs a lot of energy. When R Reagan sent a squadron of F-111s, from bases in Britain, to bomb M Gaddafi, in Lybia, it has been calculated that they could have done more damage by flying at M 1.2 and 50 m height ( both of which the F-111 is capable of ) than with all the bombs they dropped.

For a 'new guy' you know a lot. +1 and welcome

Depends on which type of Glaucoma. But, in all cases, once the pressure has damaged the 'cup' area of the optic nerve, and those cells are dead/damaged, no recovery is currently possible. ( I've had Glaucoma for over 25 years and lost vision in my left eye )

I think most of us here know how to 'handle' ourselves on the internet. I was polite in my reply. I informed her/him that I have almost a decade of posts through which people can 'get to know' me. Or maybe Science Forums is becoming the new Facebook ( or Tinder ? 😮 )

The gravitational potential of the universe would be manifest by the global curvature. Global curvature is, to my knowledge, very nearly flat. ( or within error bars of any measurements made, so far ) And I don't think you can make a distinction between observable and total universe. The global curvature would have been established when no longer observable parts of the univere were in causal contact. The gravitational field has no reason to propagate; only changes do.

Neither scale is used in Physics. The absolute scale, in o K, starts at the point where kinetic motion of particles is essentially zero, and only quantum mechanical zero point energy remains. The K and C scales differ by 273.15 o , such that 0 o C is equivalent to 273.15 o K.

No, the only time they are similar is prior to 10-43 sec. After that time, the Big Bang model is well supported by observation and currently accepted science. Maybe if you asked a few questions, and actually considered the given responses, you might understand it better, and realize there is no need for the nonsense yu are proposing. Any one here will be glad to tell you that M31 will collide with our galaxy in 4 Billion years because the two are gravitationally bound. The same reason the planets are not expanding away from the solar system, and you are not expanding away from the surface of the Earth. Dark energy, or the Cosmological Constant, is only able to overcome the very weak gravity at extremely long distances. Even galaxy clusters are gravitationally bound; it is only past those scales that expansion , and accelerated expansion, predominates.

I would guess he thinks no Communist/Marxist states have ever crashed and burned like he expects America to do.

It means the isolation during the pandemic has made her crazy. I'll have no part of this sausage fest. ( you can't bribe me with alcohol )

Nothing against M Monroe, I would think some buxom and more contemporary lady would come to mind. Claudia cardinale in the 60s ( I was still in Italy ) Raquel Weich in the 70s. Dolly Parton in the 80s. Pamela Anderson in the 90s. Katie Perry in the 00s. Scarlett Johansen in the 10s. Yeah, but he's still vertical, and still making great movies.

If your ear drum is not damaged, neither will your DVDs !!!

I gave them in my first reply. Your ear drum is much more delicate than a DVD. Does it get damaged when you hammer ? ( and for the rest of you smart-as*es, I'm referring to acute damage from a few hammer blows, not chronic danage from months and years of continuous hammering )

Yes, to the first part of your question.; sound ( pressure pulses ) will be generated in all directions. No, to the second part; the sound waves will damage nothing. The only plausible scenario is the hammer slipping out of your hand, and hitting your disc case.

Instead of always lying down with your head facing east when tanning, switch it up, and lie with your head facing west. I seriously wouldn't worry about it; skin coloration varies. If you can't get it off your mind, see a doctor.

For the oscillations of an object to diverge ( get larger and larger ), such that the structural integrity of the object is compromised ( your DVD cracks ), the force pushing it has to be provided with a specific timing ( or even multiples thereof ) so that the object, or disc, is always pushed in the same direction. This tends to rienforce the diflection until breakage. Think of a boxer on a speed bag. If it comes at arbitrary intervals, or at odd multiples, the force will not cause a divergence and failure, because each succeeding application of the force is 'fighting' the previous one. Think of an amateur on a speed bag. And then, of course, there is the miniscule amount of energy that will be transferred acoustically ( by air molecules ) in all directions ( as opposed to a specific drection ). Think of an old man on a speed bag, who keeps missing. ( sorry for the 'loose' explanation; I got the impression you're not scientifically confident )

Thanks for th link to thSokal affair, Joigus. cery interesting.

Marilyn Monroe ??? ( someone was born in the early 50s )

I doubt it very much Beecee. The current Pope was trained as a Chemist, and worked in a lab ( as well as a bouncer in a club ). Previous Popes have been Mathematicians and Astronomers. Galileo was an exception; the Vatican, and the Roman Catholic Church, have a long history of supporting the Sciences. Church has long history of supporting science - Vatican - Chicago Catholic As for Prof Reza Sanaye ... What, exactly, are you a Professor of ? Obfuscation and confusing use of the English language ? And who is the wide-eyed crazy guy in your avatar ?

GM is old school; they actually make something. I found this, in today's news, quite interesting ... "Throughout the last few months the internet has seen a surge in meme stocks (stocks which an online community, like Reddit's retail investor forum Wall Street Bets, decide to trade en masse) and cryptocurrency purchases. Another cryptocurrency called Dogecoin was created as a meme coin but experienced a meteoric rise earlier this month because Musk was tweeting about taking the coin's value "to the moon," at $1 per share (so far, it's peaked at about 7 cents). Bitcoin's value is also experiencing a steep plunge; the cryptocurrency fell about 12% Tuesday." From How Elon Musk Lost $30 Billion Overnight – and the Title of World's Richest Man (msn.com) Something is wrong, when one person ( E Musk ) with 47 Million followers, can affect the population as to the perceived value of a currency, service or even product, for their own benefit.

I can assign value to a hierarchy, and a lot of people will agree with me, and invest. Yet I ( and they ) will be charged with running a pyramid scheme. I may sell you an imaginary bridge, which you believe has value. And I'll be charged with fraud. Believing something has value, may induce you to part with your hard-earned money, but we ( and the Government ) take a dim view of some such scams. Again, you are explaining the similarities. I'm more interested in knowing why we treat them differently.

What you like to call the Big Bang 'singularity is a misnomer. Singularities of infinite density cannot exist in nature ( but of course, science has been wrong before ). It was more like a small volume of spacetime ( after t=10-43 sec ), in causal ( local ) contact, that underwent a symmetry break ( at t=10-35 sec ), and then undewent an inflationary period ( until t=10-32 sec ) which vastly increased the size of the universe, and traded false minimum vacuum energy for potential energy of inflation, such that areas outside the observable universe are no longer in causal contact. And you can see these different eras at the narrow end of the 'trumpet' pictograph. It was only after the symmetry break that particles aquired mass, and were able to move slower than c , to form atoms and matter. Google 'symmetry break', 'electro-weak unification', 'Higgs mechanism', and 'false zero vacuum energy'.
