Spooky action ping.

Physics is weird, just weird I tell ‘ya...
This is cool stuff. I own just about every book written by Wolf. A few by Talbot. A few by others. Quantum physics is a HUGE hobby of mine. The material world does not exist until particle/waves pop into quarks.
This stuff is so cool.
btt
I think a lot of these “facts” will sound laughable 100 years from now.

I don't understand it! But I love it.
Kind of like obammer and the syncophants who get "chills up their legs" at the mere metion of the saviour's name.
He doesn't understand why, but he loves it just the same!
Okay, so how hot is Saturn?? Isn't Saturn huge? Shouldn't Saturn be hotter than the Earth just based on it's mass lke this example declares??
The stuff about the “cat both alive and dead until you open a box” is complete madness. It is not a fact.
“Events in the future can affect what happened in the past” complete stupidity. Causality does not work backwards.
“Almost all of the Universe is missing” idiocy. None of the universe is missing. What they meant to say is that that our theories account for only a small part of the universe. (therefore the theories are wrong)
“an infinite number of universes existing side-by-side” foolishness. There is only one universe. Not two. Not millions. Not an “infinite” number.
“The fundamental description of the universe does not account for a past, present or future” then the fundamental description of the universe is wrong.
Other than that, it’s right.
In the Schrodinger Cat problem, the cat is very much alive, until it is dead, and the problem comes from confounding quantum mechanical phenomenoa, where the system is in a mixture of well defined "stationary states" and macroscopic phenomena where the system is in a well defined thermodynamic or macroscopic state.
The temperature of the sun, or any star, is determined by its composition, age, and mass, which establishes the rate of fusion generating heat in the core of the star. A star that is mostly hydrogen and helium burns very differently than a star that has a lot of carbon, which burns very differently from a star that is mostly metal (lawnchairs).
The theory of relativity does not do away with past and future. If an event observed by one observer can be communicated via light signals, (timelike separation) to another observer then the order of events between the two can be established. If the separation is "spacelike" ie. they are so far apart that communications in the requisite time period cannot be established, then the relative ordering is arbitrary.
My two favorite quantum physics facts posed by atheists:
1) “dark matter”, so there can be an accordion-like universe that can be explained w/o reference to a Creator, in contravention of the observation that there is not enough matter in the universe to ever make it stop expanding; and
2) rocks that can turn into people.
The wonderful world of the Brothers Grimm...
So if you change the past by observing it AND there are an infinite you’s and infinite them’s accounting for every possible history then you don’t really change the past by observation you are actually only selecting a new history to go by. How about that brain hemorrhage inducing mind trap?
Now THAT would be a heck of a "Sumore"!
Unless somebody peeled them.
Schrodinger’s cat is not dead. You only think so because you don’t see him. He is actually at a neighbor’s house where he has a different source of food, a different set of owners and a different identity.
Light speed is the speed limit of the universe. So if something is travelling close to the speed of light, and you give it a push, it can’t go very much faster. But you’ve given it extra energy, and that energy has to go somewhere.
If they are passing through an insulating medium that slows light down, they can actually travel faster than the light around them.
If the Sun were made of bananas, it would be just as hot
That's nice, except for that little thing called nuclear fusion. Despite the amount of potassium in bananas emitting alpha radiation smushing them together is not going to start a nuclear reaction.
Slightly cooler, actually. The initial compressive heat would rip the molecules apart into free H, C, O and a bit of other elements. The majority being hydrogen, fusion would begin - but there not being as much hydrogen as the sun has now, less fusion would occur. The other free elements are too heavy for the Sun to fuse, so they'd just get in the way.
All the matter that makes up the human race could fit in a sugar cube
This "10 weirdest" list shows a misunderstanding of matter being particles vs. waves. The old Boer model, which predicts this "mostly empty space" concept, just isn't strictly correct - not because it's wrong, but because it's a misunderstanding of how things work at that level. It's not so much that there's empty space, just there's less probabilities there.
If you did throw the human race into a black hole to compress it (us), the resultant nuclear slime would take up about the space of a sugar cube. Thing is, we have no subjective mental grasp of why/what that is.
Events in the future can affect what happened in the past
Well...er... Methinks the example given is a case of "observing" being a matter of influencing (see another poster's blind-man-with-a-cane analogy) that which is being observed. The photon passes thru both slits as a wave, but the process of observing "which slit did it come thru" causes a wave which cancels out the wave signature regarding the other slit. Kinda like "noise canceling headphones" which silence a sound by playing that sound, inverted, at the same time. (Ok, that's my guess on the issue. Point is there's more to what's really going on than an ignorant "hey! it's time travel!")
Almost all of the Universe is missing
I'm chalking the "dark matter & energy" theory up to scientists observing a phenomenon they are unaware of, and imposing inapplicable concepts thereon. Kinda like the long-held theory of "ether" being the conduit for light - until someone proved there isn't any.
Things can travel faster than light; and light doesn’t always travel very fast
Nothing travels faster than light. What "slows" light is the interaction of light with the physical medium it passes through. You might be able to run X MPH, but put a parking lot in your way and you'll slow down while going around/over/through cars. Some things might interact with that physical medium differently, giving it a speed advantage and thus some novel effects - but casual discussion ignores the fact that impeding medium aside, light is still traveling faster.
There are an infinite number of mes writing this, and an infinite number of yous reading it
We don't know, and by definition can't know, what's "outside" the universe. Professional thinkers kicking around novel concepts end up with some pretty strange theories as a result (which may explain why Leftism is so popular on campus). Kinda like Netflix radio commercials: Q. If a rhombus has four sides, what is the inverse of blue? A. Purple
Black holes aren’t black
The hole is black. The barely-escaping bits of matter being ripped apart while crossing the event horizon isn't.
Vague analogy: a white wall isn't white, the "white" is just the thin layer of paint on it.
The fundamental description of the universe does not account for a past, present or future
An incomplete comment; the text goes on to observe "...Time frames are relative". The fundamental description of the universe DOES account for a past, present and future - but their arrangements around stuff is a lot more complex (based on relative speeds) than just A past, A present, and A future.
A particle here can affect one on the other side of the universe, instantaneously
Ok, that one (to wit: paired particle spin) is just plain weird. Kinda like Schrodenger has two boxes containing twin live/dead cats: open one box to find a live cat, you just killed the other one.
The faster you move, the heavier you get
Makes perfect sense - if you understand "relativity".
Maybe this is why Americans have a cumulative weight problem - we're all running around so fast.
