VARIOUS & SUNDRY 17

(202109223) University/College Dorm/Room Problem:
IMHO, it is extremely important for people who plan/design college dorm buildings/projects to understand that living w/ roommates is NOT for everybody! (& living off-campus is NOT a solution for everybody!)
Apartments shared between multiple roommates cause/create so many issues/problems (which maybe no big problem for some, but definitely are big problems for others)!
For example, shared electricity/water/gas/internet/TV bills almost always cause unfairness for some roommates!
Common temperature setting causes many to live/study uncomfortably!
Shared fridge causes food/space sharing issues!
Often kitchen or bathroom is occupied, when also needed by another roommate!
Often there are incompatibility (introvert vs extrovert situation, for example) between some roommates (causing unhappiness (even arguments))!
Sharing cleaning & trash handling & toilet paper costs etc often causes problems!
Solution:
IMHO, providing plenty of single-occupancy micro-apartment dorms (for equal or less rent amount!) needs to be mandatory for all college dorms!
(IMHO, universities/colleges should/must do surveys & ask their students:
Would you choose shared or unshared dorm, if rent amount for both was equal?
(My guess is most (if not all!) would choose unshared dorm!))

"Dark energy might be neither particle nor field"
https://www.patreon.com/posts/dark-energy-be-56455580

IMHO, there is also another possibility which is Dark Energy maybe coming from outside of our universe!
(Such possibility would also preserve law of conservation of energy!)
(I had seen toys which were little pills, which grew into much larger toy animals, when thrown into (hot) water! What if our universe is similar? :-)

(Not to mention, what if, physically only real & virtual particles exist & all "fields" (& spacetime) are just mathematical idealizations (actually created by the medium of virtual particles everywhere)?)

(202109267) Ultimate Motorhome/RV conditions/properties/features:
1: Electric AWD All-Terrain (mini)bus (w/ hub motors)!
2: A (replaceable/swappable) battery unit (w/ max possible power/capacity/duration) provides power to the vehicle & everything inside!
3: Covered w/ solar panels (on roof & 4 sides) which continuously auto-recharge the battery unit!
4: Flex-fuel/(bio)diesel gas turbine (or Wankel engine) electric generator which continuously auto-recharge the battery unit (as long as kept turned-on)!
5: Fully self-contained micro-home w/ shower & toilet & kitchen & bed & table(s) & chair(s)!
6: The vehicle & everything inside are made of max durable materials: stainless steel, aluminum, carbon-fiber, plastic etc!
7: A water generator (which generates water from moisture of outside air) continuously auto-refills the water tank of the vehicle!
8: Satellite-based internet service!

(202109271) Some interesting (IMHO) future events, according to (Sunni(te)) Islam:

When someday sunrise starts to happen from the west (& sunset at the east) (which is one of the big signs of end times!), then, all non-muslims will accept that (Sunni(te)) Islam was right all-along & so, it is the true religion of God, but God will NOT accept them as true believers of Islam!

At the day of judgment, the people to be send to Hell for eternal punishment will tell God (paraphrasing):
"Now we saw that what we were told/warned about was true! Send us back to the world & we will behave good!"
But, God will refuse (basically)!
& later they will ask God (paraphrasing):
"Is there any way out for us?"
& God will say no (basically)!
& sometime later, when they are in Hell (& keep burning!), they will ask warden angel of Hell (paraphrasing):
"Beg to God for us to let us die!"
& the angel will refuse (basically)!

(& by the way, according to (Sunni(te)) Islam, 99.9% of whole humanity will go to Hell!)

(202109282) IMHO, neither religious nor non-religious people have a right to impose/force their will on each other, by using the power of law/government!
For example:
Would I support a law to make using alcohol and/or all (overdose-safe) drugs banned/illegal for all adults?: Absolutely NOT!
Would I support a law to make using alcohol and/or all (overdose-safe) drugs mandatory for all adults?: Absolutely NOT!
Would I support a law to make assisted-suicide banned/illegal for all (severely unhealthy/unwell/unable) adults?: Absolutely NOT!
Would I support a law to make assisted-suicide mandatory for all (severely unhealthy/unwell/unable) adults?: Absolutely NOT!
...

(202109293) R&D work needed to create the real/true TOE:
1: The real/true (Quantum-Relativity) GUT needs to be created (by mathematically showing/proving spacetime (superfluid emergent property) created from gas-like medium of virtual particles of quantum vacuum)!
(Since accurate/realistic simulations of classical fluids require practical full-scale classical computers, accurate/realistic simulations of superfluids would require practical full-scale quantum computers!) (& if so, then, quantum-version of LBM-CA algorithm needs to be developed to simulate 2D/3D superfluids!)
(Classical LBM-CA enables accurate/realistic simulations of classical fluids but I am guessing it cannot simulate dynamics of phonon quasiparticles (because that would require quantum computer/algorithm)!)
2: Start developing accurate/realistic simulations of dynamics of all known quasiparticles (using 2D/3D CA grid/matrix/crystal algorithms running on quantum computers)!
3: Start developing accurate/realistic simulations of dynamics of all known real/virtual particles (using 2D/3D CA grid/matrix/crystal algorithms running on quantum computers)!
4: Unite/combine simulation models/algorithms of all known real/virtual particles into a single model/algorithm!

"Could there be a parallel universe identical to our own?"
https://www.patreon.com/posts/could-there-be-56743533

My guess is that, if the many-worlds interpretation of quantum mechanics was really true, then, as we keep getting right answers from our quantum computers, in countless other parallel worlds, quantum computers would be keep giving wrong answers! :-)

(202109304) Additional comments on the same article above:

I think the main reason why many-worlds interpretation of QM cannot be right, is because it would really require each & every quantum measurement/branching create new copies of our whole universe! (Which is an idea I had read before but did not know/understand why that would be required!)

For example:

Imagine that, a physicist is making a measurement on a single particle!

If many-worlds interpretation of QM is correct, then, surely there would be countless parallel scientists making the same measurement!
Are they all measuring the same single particle?: Surely NOT!
& so, then, we are forced to conclude that, each & every quantum measurement/branching should/must create new copies of measured particles!
(Completely going against conservation of energy/information!)

(Not to mention, where each newly created/copied particle would exist?: In its own universe!
So, whole universe needs to be copied; not even just the measured particle! :-)

Here is another thought experiment showing the problem w/ MWI:

Imagine that, I made a measurement on a single particle & it branched into 2 separate reality versions!
If I continue to observe one of those reality versions then there needs to be another me to continue observing the other reality version!
& that (again) means each quantum measurement should/must actually cause whole universe to branch! :-)

(202110052) IMHO, elementary/composite particles do NOT have constant & identical internal quantum states (between same types of particles)!!!
Some evidences:
Pauli Exclusion Principle (which prevents White Dwarfs from collapsing by preventing electrons to be in the same (internal) quantum state & prevents Neutron Stars from collapsing by preventing neutrons to be in the same (internal) quantum state)!
QED (which is extremely well verified!) says electrons have ability to (temporarily) absorb photons (which implies internal state change)!
Stern-Gerlach Experiment shows electron beams getting separated (into 2) by a magnetic field but identical magnetic field cannot do it for a second time! (If the electrons still have same identical internal states then why?)
(IMHO, quantum particles are just clusters/registers of qubit/qutrit (state) data (w/ some values constant & some variable)!)

(202110052) IMHO, end of the world/humanity will NOT be because of any kind of natural/cosmic/scientific/technological disaster!!!
IMHO, it actually will be the way described by (Sunni(te) Islam (which provides lists of small & big signs for the end coming/approaching)!
(For example, one of the well-known small signs is, people/countries racing to have the highest building in the world!
& for example, UAE built the highest building in the world by far years ago & currently Saudi Arabia building another one far higher!
(& I think it is interesting that both buildings/countries are located at Arabian Peninsula which is the birthplace of (Sunni(te)) Islam!))

"Why “chaos and complex systems” absolutely deserves 2021’s Nobel Prize in physics"
https://www.patreon.com/posts/why-chaos-and-in-57063537

"Complex systems can exhibit aggregate behaviors that only emerge from the interaction of many smaller, simpler systems."

Just like how all kinds of fluids emerge from aggregate behaviors of individual particles/atoms/molecules moving/interacting in random-fashion!
(Which is also the problem of Quantum-Relativity (IMHO):
How exactly aggregate behaviors of virtual particles of quantum vacuum could create a spacetime superfluid?)

"The science of how Earth will meet its ultimate end"
https://www.patreon.com/posts/science-of-how-56970273

& by the way, "migrating the Earth farther away" option is the plot of this Chinese movie:

https://en.wikipedia.org/wiki/The_Wandering_Earth

(IMHO, turning whole Earth to a mobile planet, also would be the best/safest way to take humanity to other stars!!!)

(202110074) Additional comment on the same article above:

Imagine, if whole Earth is covered w/ a grid of supertall (higher than atmosphere!) thruster towers powered by fusion!
They could be ion-drives using something like (ionized) water for example!

But I think laser propulsion could be the answer (which would not require any fuel)!
(Imagine, giant arrays of countless lasers on top of each tower!
(Photons have momentum, so any laser (or bright/efficient light source) could act as a drive in space!)
(Of course, such pure electric propulsion tech (if developed) would be really useful for satellites & space probes too!))

"These 5 recent advances are changing everything we thought we knew about electronics"
https://www.patreon.com/posts/these-5-recent-57106604

"One of the most egregious example of where technology has failed to advance is the battery, as we pretty much store electric energy with dry cell chemical batteries, a technology that’s centuries old."

I think what could take battery tech to a whole new level maybe:
https://en.wikipedia.org/wiki/Flywheel_energy_storage

IMHO, current flywheel energy storage tech is still far below/behind its max theoretical limits!
Imagine that small battery devices w/ one/multiple flywheel(s) spinning inside vacuum (suspended by magnetic fields)!
Realize that such flywheel(s) maybe made to spin close to relativistic speeds!

"Can we use a giant thruster to change Earth’s orbit?"
https://www.patreon.com/posts/can-we-use-giant-57300263

I knew it! Thanx Ethan! :-)

But also:

We are talking about extremely distant future & you assume still there is no fusion power available?
(I for 1 think that practical fusion power is definitely possible!)

I also think that covering whole Earth w/ a grid of (equidistant) supertall (higher than atmosphere!) giant tower thrusters would be a superior solution!
(Keep in mind that their firings can be timed (by taking into account rotation of Earth!) to be always on the same/any side we want!)
Because then, Earth could be moved in any direction (like when eventually if we decide to travel to another younger star system)!
