Time travel proven at the quantum scale: physicists

[Kaii]

The video talks about two-dimensional beings and how they would experience the world.

Does 2 dimensional beings exist? No. Does 4 dimensional beings exist? No.

At least not yet.

Speculating to the existence of 4 dimensional beings is no better than speculating about God.

Quantum Mechanics imo, and we had the discussion, is a fraud and many physicists seem to agree. QM seems to be a descriptory mathematical abstraction to explain certain physical phenomenon, but not a rational logical physical theory.

For example, Newtonian gravity theory has been proven false, yet it is a good enough approximation to fire a rocket to the moon.

QM is the same, a good enough approximation to predict some things we don't understand, however the premises of QM which go against classical mechanics - and classical mechanics is the reason you car drives or your plane flies - and are obviously semi-superstitious in nature such as postulating a particle can exist in several places at once or in several times at once.

That is just pure bs and the proof is that if you critize these absurd ideas then you will be viciously attacked by the cult of QM.

I'm not a scientist by any means. Are you saying QM is basically bunk science? If so, I'm a bit disappointed then. I get excited when I read about some of the QM things on science websites and such.

I'm surprised more wasn't made of this at the time - the article dates from December 2015.

I'm not surprised. The MSM's bread n butter is the clown show: Just wiggle meaningless shiny shit in front of the masses.

Thanks for calling this out. This and the recent identification of gravity waves are IMO seminal discoveries

My understanding is that traveling backwards is virtually impossible but traveling forward is very possible if you can find a vehicle that can go VERY fast. Essentially, you slow down time for yourself relative to everyone else on the Earth.

The theory being, if you could get a VERY fast spacecraft (like near light speed fast) and orbit the planet; people would age much faster than yourself. Don't ask me why or how; that's all I really remember. But the science is quite clear if I recall; we just need something that can transport us VERY fast and allow us to survive the trip. I think the movie Interstellar sort of touched on the subject.

The phenomena is called time dilation. As you come closer to approaching the speed of light, time moves slower relative to outside observers. An explanation that I've heard is that if you were to reflect light between two points within your spaceship, which is traveling parallel to the outside observer, as you approach the speed of light, the distance the light which is bouncing between the two points on your spaceship would travel would be much, much longer than distance which the light that directly reaches the outside observer. I read about it in a book and asked my physics professor after class if he could explain it in a simpler way, and he said that's the way he was taught. Graphically, it might be described this way:



As you reach significant percentages of the speed of light (>90%) you would age considerably slower relative to people back on Earth.

Interesting, this basically sounds like the premise of the movie Interstellar in which the main character travels to some far solar system, and eventually his kids age much faster then he does. Also, I recommend watching that movie for the science fiction aficionados here.

Sadly, it's not the first time I've heard it. There's a whole little tradition of anti-Jewish "physics" produced by cranks.

What is anti-Jewish physics?

It's what allegedly kept the Nazis from developing nukes. They didn't want to benefit from "Jew science".

What, specifically, are "anti-Jewish physics"?

That's what was stated: that there was such a thing as "anti-Jewish physics". Not avoidance of "Jewish physics".

Actually the principle of an anti-jew is a well-established principle in quantum theory. Anti-jews are essentially jews moving backwards in time, and thus we perceive them as having opposite electric charge. For example if you rubbed a balloon it would repel from an anti-jewfro. The practical result of all of this is that if a jew and an anti-jew come into contact with each other they mutually annihilate and convert the sum of their mass-energies into a burst of gamma rays. Such an event would be catastrophic given the combined mass of two ninety pound jews converted into photons could vaporize the Earth.

Thinking about this stuff makes my head spin if I think about it too long. It is too much for me to grasp.

If you're interested in this, I strongly suggest reading The Science of Interstellar. It was written by the main science consultant for the movie.

To make a long book short, the "time travel" portrayed in Interstellar is theoretically possible, based on having the biggest spinning black hole that could exist, and a planet orbiting the "lip" of the black hole's spiral. Imagine putting one of those pennies into a big spiral thing you see at the mall, except instead of eventually dropping down the (black) hole, if stays suspended in "orbit".

Add in the tidal forces of a more oval/shaped hole and you get the technically realistic super gigatic waves on Miller's water planet.

I find this stuff absolutely fascinating, and am surprised how many people know the whole e=mc^2 thing, but don't really understand the finer points behind it. I've watched probably a hundred hours of videos on this stuff.

https://www.youtube.com/channel/UC7_gcs09iThXybpVgjHZ_7g is an excellent channel with a series of ~10 min PBS shorts all about this stuff.

As for the time dilation, the main thing you need need to get your head around is that the c is the only universal constant. Not distances, not how fast time ticks. In normal Newtonian physics, if I'm driving at 100 kph, and throw a ball at 30 kph, it will hit you on the ground at 130 kph (the two speeds added, but meanwhile I saw the ball leave at 30 kph). However, if I'm driving at you and shine a light at you, I see the light leave at the speed of light. So according to Newton, you should see the light coming at you at speed of light, + 100 kph. This isn't what happens though. You will see the light coming at you at *also* the speed of light. How can that be? The way this is reconciled is that you have clocks running at different rates. Literally the clock of the person in the car is going slow. 1s of his time is equal to 1.0000000005s or whatever of yours. However, this is imperceptible because heart rate, thought processes, everything also slows as well. Now, this isn't really noticable unless you get super precise, or go very near the speed of light.

Which leads to the other interesting thing is that this has all been verified experimentally. When you put on atomic clock on a plane and fly it around since it operates to a accuracy of about 1/10billionth s, is you can literally see the difference. Similarly, the clocks on board GPS satellites need to be corrected to account for both that they are moving fast, and that they are in a different gravitational field (clocks also run at different speeds on the top of mountains due to weaker gravity...)

So that said, "time travel" is very possible in a real sense, but only forward. There are some ideas about worm holes spontaneously coming and going at the tiniest levels linking different times which might leave the door open for backwards, but that is all very theoretical at this point....
