What would happen to space if passage of time was accelerating? Equality principle. Similarity of empty space. A Shrinking matter theory that might actually work.
Even the most simple concepts, such as mass, don't scale well. Shrinking distances by half, would result in shrinking mass to one quarter, as it depends on volume. That extra quarter of missing mass simply disappears in your theory ? Does the Gravitational constant change over time to account for the difference in force over time due to the downscaling ? I can come up with many, many more effects that would need more and more assumptions and changes to modern Physics for your theory to be viable. The current theory does not need any !

GR and cosmology (split from …A Shrinking matter theory that might actually work.)
I think a reality check is in order before this goes farther ... Bangstrom ( and Caracal, in the other thred ) does not seem to realize how expansion actually works. The Cosmological Constant, responsible for expansion, is just that, a constant term appended to the Einstein equations which describe gravity, which acts 'opposite' the gravitational term, and was originally intended to balance the equations so as to keep the universe static. Since the gravitational terms are variable, but the onstant is not, its effects only become apparent when the gravitational terms are weak enough that the Cosmological Constant exceeds them in magnitude, and the Enstein equations then no longer result in attractive gravity, but rather, cosmological expansion. IOW, we would see expansion only when gravity is weak enough that the Cosmological Constant is able to exceed the threshold of gravitational attraction. And the really great part is, that is exactly what we observe. We don't see spaces between our constituent atoms increase, or the Earth getting larger, or planets and stars moving apart, or even galaxies getting bigger, simply because they are gravitationally bound, and the Cosmological Constant is very small, and below the threshold of the gravitational attraction. We start to note expansion at large intergalactic and intergalactic cluster distances, where gravitational attraction is very small, and the Cosmological Constant tops the threshold of gravitational attraction, and exceeds it. That observational evidence fits in neatly with our theoretical assumptions. A 'shrinking everything' theory, assumes that everything shrinks in scale so that all effects are preserved . ( and as Markus argues that isn't possible ) But we know , from observation, that there has to be a 'cut-off', where, below intergalactic scales this effect is no longer apparent. So either your theory is a non-starter, as it doesn't apply to the reality, or, you need to get back to the drawing board, and come up with a suitable mechanism for your theory to maintain the observed cut-off, and comply with reality.

How Trump Could Steal The Election
Maybe he thinks if he saves the day in Ukraine, with a plan to stop the Russians, he's got a chance of getting re-elected. I hear he proposed using F-22 with fake Chinese markings to bomb Russia. Almost as sensible as drinking bleach to cure Covid-19. You see all those people in Russia who have no idea what's happening outside their borders because of government controlled news, and who believe everything V Putin tells them. Yet in America, with all information freely available at your fingertips, a large number of idiots still believe all the crap that D Trump spews. Iwouldn't believe it could be possible, but it is still happening. Can't believe I missed this ... Some people would say I'm still an ass, now.

War Games: Russia Takes Ukraine, China Takes Taiwan. US Response?
On first view of videos coming out of Ukraine, you feel sorry for the displaced women and children, the destruction and the suffering, and the deaths of Ukrainians who, just a week ago, were living their lives and going about their business. Some of the graphic videos on Reddit also show what is happening to the Russian soldiers; young kids, scared and confused, some dying in brutal fashion. I feel sorry for them too. All this misery to satisfy the ego of a deluded man who yearns for the long since past glory of 'empire'.

A question for the smarty pants.
While the density of depleated Uranium is useful in increasing the kinetic energy ( stopping power/penetration of tank armor ) of artillery shells, such as those of the General Dynamics GAU-8 gun of the A-10 Warthog. it it is useless ar a factor for reactivity with acid. Lead-acid batteries exploit the red-ox reaction of the outer valence electrons.

Nuclear reactor technical discussion (split form War Games: Russia Takes Ukraine)
Hopefully Ukrainian nuclear power plants of recent years have built-in redundant safeguards against fires like Western power plants. I'd hate to see another Chernobyl.

The equation of dark matter; amazing theory
Why not ask questions about what you don't know, rather than posting nonsense ?

Objective Frame of Reference
That is essentially correct, and depends mostly on the model being applied. A classical point particle has no expectation of decay. A quantum particle, which can decay, cannot be localized to a point, because of e the Heisenberg Uncertainty Principle, and the fact that, in QFT, the particle is simply a manifestation of its field. But the OP was asking about a point at the beginning of the universe. A point with no exterior as it encompasses the whole universe, and no internal structure or mechanism/process. So what exactly would cause the transition to expansion/inflation ? The actual universe is believed to have had a finite initial size, which was subject to quantum fluctuations, and may have initiated its expansion/inflation and subsequent structure.

Objective Frame of Reference
A singular point cannot have any internal attributes that would cause it to become unstable, or inflate. No vacuum fluctuations, no vacuum pressure or false zero energy levels, no Cosmological Constant, etc. So what caused the original expansion/inflation of the Big Bang ?

I'd prefer a Benelli M4 in a home invasion situation. Only because the Franchi SPAS 12 is prohibited in Canada.

The speed of light varies across the universe...a theory
If you attempt a meaningful post on a science forum, you should, at least, know the difference between mass and weight. If you don'twish to continue being ignorant of such matters, maybe you should ask. Might save you some more embarassement.

Are Swansont/Phi For all etc university science professors/lecturers/scientists?
You'll have to teach me how you did that. Every time I lock myself out of the house, my cat just looks at me from inside with disdain, no matter how much I implore her to open the door.

War Games: Russia Takes Ukraine, China Takes Taiwan. US Response?
I think V Putin should be scared. Hopefully he will be removed from office, sooner rather than later. And if he attempts to go nuclear, saner heads prevai, and he is killed.

War Games: Russia Takes Ukraine, China Takes Taiwan. US Response?
You are right, Swansont, veto was the wrong word to use, but the situation with the East Med is still unclear since the US pulled their support in January. As for Keystone, it was meant to join up with other pipelines to get oil to ports in the Gulf, where the refineries and ports for shipping are. While it would have been nice if places like Germany had started their transition to green renewable sources decades ago, 'what if' scenarios don't help with the current situation/problem of dependence on Russian resources.

Why is a fine-tuned universe a problem?
Would like to hear those arguments, Joigus. When you have time, of course.

Whoa ! Who has time to read all that ? I'll address your first point about how closely electrons can pack ... ( which is different from being in the same 'state', and governed by the Pauli Exclusion Principle ) No. It has more to do with spin. Half integer spin particles, or fermions, obey Fermi-Dirac statistics, and cannot be 'stacked' on one another. Integer spin particles, on the other hand, are bosons, and obey Bose-Einstein statistical rules, and can be stacked on one another.

Covid : Mild Covid can increase aggression
He would have had to be suffering from a Covid infection since the late 90s. Ever since the destruction of the city of Grozny. Battle of Grozny (1999–2000) - Wikipedia Of course, back then the Russian military was a lot more capable and fearsome.

War Games: Russia Takes Ukraine, China Takes Taiwan. US Response?
Regarding energy policy, INow, a Couple of missteps by J Biden ... Israel has an abundant supply of natural gas from off-shore wells, and is already supplying gas to Egypt and Jordan. They have capacity to spare, and plans were in the works to build the Med East pipeline to Europe. Until J Biden vetoed it earlier this year. Canada wanted to build a pipeline to the Eastern seaboard, where gas could be liquified and shipped to Europe. Again J Biden vetoed their construction. They might not have helped in the short term, but would spare Europeans from having to deal with the devil ( V Putin ), and keep enriching him and his cronies. Might still be time to revisit those vetoes. On another note, if Belarus sends in troops to support the Russian invasion, does that give other countries 'wiggle room' to send in troops to supprt Ukrainian resistance ?

War Games: Russia Takes Ukraine, China Takes Taiwan. US Response?
More like Russia sprang forth from the Ukraine. The original people, who settled/cultivated the area of present day Ukraine called themselves the KievanRus, where the 'rus' denoted their red-haired Nordic ancestry. Kievan Rus' - Wikipedia The steppes of present day Russia were the domain of the Mongol, or Golden, Horde in the South, and mostly barren Siberian wasteland to the North. Well at least this time you chose toexplain instead of simply downvoting. Much appreciated. What kind of description is it to call someone's behaviour 'dick'-like, and then have that post magically disappear, so that my angry response is the only one visible, and I look bad ?

Why is a fine-tuned universe a problem?
Supersymmetry was also proposed as a way to get rid of all the excess energy of the vacuum predicted by QFT, by destructively interfering all the contributions by regular particles with those of ssparticles. This would have effectively made vacuum energy equal to zero, which also cannot be right as we have a very good approximation of the vacuum energy required for expansion, about the order of 10-8 ergs. And since QFT ( with just regular particles and a Planck cutoff ) predicts a vacuum energy of 10112 ergs, we have a vacuum catastrophy of 120 orders of magnitude.

Why is a fine-tuned universe a problem?
For the OP to make sense, one must first establish that the universe is 'fine tuned'. No such thing has been established, so it is a bit presumptuous to call it a problem.

War Games: Russia Takes Ukraine, China Takes Taiwan. US Response?
For all intents and purposes, Russia, and V Putin has already lost. They have become a pariah state, which most of the world has turned its back on, and, what was expected to be an '11 min' action to overthrow the elected government of Ukraine has exposed deep weaknesses in the Russian military forces. All they can do now is contnue punishing the Ukrainians, and make blustering threats with their nuclear arsenal. Sooner or later, the military, if not the people, will remove V Putin for all the useless harm he has done.

A pro Putin section in the US?
I wonder if that spike in popular support for Russia in 93, corresponds with B Yeltsin standing on top of a tank, holing the Russian flag, in defiance of the hard-liner Generals who wanted a return to Cold War ways. I guess those Generals finally won when V Putin took office.

SCOTUS and the US constitution (split from The next Supreme Court judge)
It was 'justified' at the time by having the measure of a colored slave as a fraction of a man. In which case it was 'self evident' to them that slaves were not fully men, and therefore, not equal. It takes some pretty tangled thinking to justify such brutal acts. ( and it goes on, to this day, in the Kremlin, to justify war on Ukraine )

A pro Putin section in the US?
D Trump is an imbecile and a continuing joke. However idiots like T Carlson and T Gabbard ( who I have lost all respect for ) are taking this opportunity to attack President Biden while making excuses for V Putin. And they call themselves patriots ....
