Yeah, I guess Phi and I had been agreeing too much lately; that's gotta stop. ( and this is meandering a bit off track ) Nobody is 100% good or 100% bad. We admire people for certain things they do, because those things are important to us at certain periods in time, and we ignore unsavory actions they may take, because they are not important to us ... at that point in time. As our sensibilities evolve and change over time so do our priorities, and things we may have ignored hundreds of years ago have now become despicable acts. I don't judge the past with today's viewpoint and sensibilities. And the acts for which they were admired, still deserve admiration. I don't want to get religious, but someone once said "Let he who is without sin cast the first stone." It's highly unlikely, but, who knows, maybe someday even D Trump will be remembered for one good thing he did. ( although I can't think of anything )

Yeah. The Injustice Department released a batch of files also, and they contained references to multiple UCP. ( Unidentified Criminal Perpetrators ) And some of these UCPs may be DJTs. Is there no end to the lengths he'll go to in order to distract from his criminal activities ?

Sure, but the time span I mentioned is 1040 years. How much Rubidium 87 will be left after Ten Thousand Billion Billion Billion Billion years ?

not sure what advantage us gained by increasing the density of the water to a slurry. Sure, you can use a lower height for storage, but the pumping load increases proportionately with the increase in density. I haven't done, or seen, calculations so I'm not sure of any benefits other than convenience of using existing geological formations.

Photons of the CMB have red-shifted from 3500o to 2.7o in 1.4x1010 years. Once all the stars burn out ( say 1020 years ), how long do you think it will take for any of their emitted photons to red-shift to an energy where they can no longer excite fundamental particles? Another 1010 years ? What will they be then ? At that time, the only source of useable energy might come from proton decay ( assuming it actually happens ).

To be clear ... There is no incompatibility between Gravity and Quantum Mechanics; they both work seamlessly at all scales, and have always done so. The incompatibility is in our models with which we describe them. IOW, we need better models, because the current ones are incomplete for some situations.

These Billionaires make their money from investments. That's why D Trump keeps insisting the 'economy' is good; the stock market keeps going up. Their economy is doing great. The rest of us are subject to a different economy, where we have to work, at low wages, to buy food, housing and gasoline at the inflated prices that are fueling the stock market. The rich get richer, and the poor get screwed ... again.

Once protons start decaying at a minimum of 1034 years, I can't imagine any living things to be around ... Omce our galaxy is the only gravitationally bound system in the observable ( causal ) universe, how would you determine growth of the scale factor ? No, I've already had second thoughts about the situation in a previous post. Oscillations between energy levels of fundamental particles ( no decay ) would be governed by the energy/time uncertainty relation, making time an essential factor.

Don't have much time as I have a busy day ( I thought those were over once retired ) but I just had to reply to this. Facts are global ( apply to everyone - objective ); truth is local ( applies to one person - subjective ).

I wasn't thinking of Quantum fluctuations as typically understood, but rather fluctuations around the final equilibrium of the maximal entropy universe. But you do bring up a good point. The Quantum fluctuations due to the Uncertainty Principle cannot be ignored as they are a necessity of Quantum systems. The energy-time uncertainty dictates that their deltas must be greater than , or equal to, h-bar/2. IOW, 'borrowed' energy for the fluctuation must be re-paid within a specific period of time. As this is a process that even maximal entropy cannot stop, time IS still needed.

Interesting question. But keeping in mind that ALL processes would be halted, and QM oscillations could go backwards or forward, there would be absolutely no way to detect the passage of time. If time is redundant, would it still exist indepenently ?

Science based on word play. Who would have thunk it ...

Well ... possibly. Once maximal entropy is reached, and the universe is essentially at equilibrium, no processes can go forward or backward. Sure, there will be some small oscillations about the equilibrium state, because of QM, but how would you measure the passage of time ? ( if this wasn't off topic, it would make an interesting discussion ) Edit - I see you fixed that problem. Thanks.

Further to the international damage done by this Administration, here is a commentary on P Hegseth's visit to the American cemetary in Colleville-sur-Mere in Normandy, for the D-day anniversary. Those dead and buried soldiers would be severely disappointed to have given their lives so that idiots like P Hegseth, and the rest of the Administration, could dishonor them. They have no idea what those soldiers fought, and died, for.

The national mistakes made by this administration might be fixable. The international mistakes not so much; too many 'alliance bridges' have been burned, and no one will be willing to take those risks again.
