In regard to the distortion of the spinning merry go round- the radius immediately from the rider to the center would be unchanged, but all of the other radii on the circle would be contracted, according the sine of the angle between the radius and the rider's radius. So the shape the rider sees would be a rotating ellipse, according to Lorentz. So it is true that the geometric relation of the radius and the circumference would appear not to hold in the rotating reference frame. But that does not pose any problem, if the rotating reference frame reports an ellipse, rather than a circle. I am trying to figure out what observation would require you to resort to curved space time, to account for it. There would be angles that the rider could see around the elliptical shape, that a stationary rider would not be able to see around the circular shape. Similar to gravitational "lensing". But it does not seem that that requires curved space time, either. Because those same angles would be visible to the stationary rider, at different times. Something to think about.

I don't understand why everyone is so surprised that the universe is random. Life... For instance... Nothing is 100% predictable in the end it's all governed by quantum mechanics and it scales up to macroscopic sized things through DNA. Search for the preons. But I doubt it stops there, it's all fluid.

I dont see how it follows if you treat people like computers you can destroy society... Of course this is possible. Its also possible to destroy or put another way, become evil while still treating people like people. Conversely since ive abandoned free will I feel more sympahy for humans as creatures or machines or whatever you want to call them, its all the same.

If everything is quantum waves in Einstein's time-space understanding the quantum entanglement of particles is closer to the advancement of overall physics. May the pioneers keep pushing forward. I especially like the equal and opposite spin after the measurement. I am exploring spin propulsion

If there was a big bang and particles get entangled when they are created. Then all particles in the universe got entangled when they were created from the big bang. If they all communicate faster then light they might communicate across time as well. The question is why can't I use them to send myself winning lottery numbers?

Conjecture module and theorem prover module are interesting. I don't see a problem though. We'll just need a third module: the translator module! In general, whenever someone conceives of a problem with AI, surely just think of this problem itself as a computer science problem, then there will also be an AI solution?

Quantum mechanics imply multiple extra dimensions within the one universe. Assuming it indicates entire multiple universes is a huge stretch and leap. I enjoy Brian Greene, by Sean Carroll is pretty good.

Where is the ruliad a better perspective than topos theory? Is there a way of composing rules to tie them to things like fundamental constants inherent to the theory? I feel like the kind of relativity the ruliad speaks to is inherent to humans. Feels like a teaching tool almost, to open researchers mind.

You must be the alpha on your own brain. You command him with your power that was given by God as long as you understand love and Gods love. With that access you can command your brain at anything you want to have as a human as long as it is possible for a human body. Anything is possible, because of brain i could probably create stars and planets. Amazing right?🥰

When I think about densities and then I address the issue of time space itself I find it hard to believe that Time exists without the fact that vibrations FALLOW a path that time cant slow down or speed up the pathways itself is entangled with the reflection of the vibration that makes it continuously floating in the spacing process circles within circles of billions of trillions of particular vibrations Crystals record the tracks of time space itself vibrations are exactly what we are experiencing

General relativity and quantum mechanics will never be combined until we realize that they take place at different moments in time. Because causality has a speed limit(c) every point in space where you observe it from will be the closest to the present moment. When we look out into the universe, we see the past which is made of particles (GR). When we try to look at smaller and smaller sizes and distances, we are actually looking closer and closer to the present moment (QM). The wave property of particles appears when we start looking into the future of that particle. It is a probability wave because the future is probabilistic. Wave function collapse happens when we bring a particle into the present/past. GR is making measurements in the predictable past. QM is trying to make measurements of the probabilistic future

3 observations: 1. The example of the backpack (how you perceive an uphill road in front of you as steeper if you have a heavy backpack on your back) is interesting and congruent with Bergson's idea that perception is virtual action, action-oriented in the sense that it prepares us for action. 2. I find Hoffmann's and Seth's narratives a bit pernicious. The way they push the idea that we have no access to what reality "really is" (Hoffmann) or that perception is "controlled hallucination" (Seth) is an exaggeration, but also a bit of a dangerous one. One thing is denying naive realism, another thing is undermining our "contact with reality" completely. It is, after all, a performative contradiction, because science is done by human beings with those same perceptual limitations, so they are essentially cutting the tree their own scientific conclusions sit on. We have direct contact with reality because we participate in reality. The fact that perception is "transjective" (neither fully objective in the sense of independent of the subject nor fully subjective in the sense of mere creation of the subject) doesn't undermine that. 3. As Varvaeke would say, "real" is a comparative notion, like "tall". You say that something is real as compared to something else that is not, or that something is "more real" than something else, and that is contextual. The chair I'm sitting on is more real than its reflection in the mirror, if by real I mean that I can sit on the former but not on the latter. My brother is more real than Sherlock Holmes if by real I mean my brother is a human being in flesh and bones that I could play tennis with (while Sherlock Holmes lacks such physicality). The park outside my house is more real than a park I may have dreamt of last night, if by real I mean, again, having physicality, being better defined, having more stable presence, etc...

This was a very good video description by Dr Green which explains what happens with time dilation, but I still can't understand why. I do understand that the object that is accelerating makes time slow down for them, but what if 2 objects traveling at a cruising speed of 99.9% the speed of light, each flew by each other, let's say somewhere between the Earth and the moon. One of them traveled 5 light years to a star in one direction and the other traveled the same distance to the nearest star in the opposite direction. How much would the observer on Earth have aged to the astronaut's point of view and how much would the astronauts have aged in comparison to each other? also, each ship would have a very bright rounded beacon light which the earth observer would be able to see as they crossed each other.

I think there's different kinds of dark energy. In the early universe the nuclear force dominated and produced "nucleated dark energy" because the universe was so tiny that atomic forces were prominent. And now that quantum gravity effects have become prominent as the universe expands. "Quantum dark energy" is the prominent form of dark energy. Nucleated dark energy still seems to exist unchanging though as it's many orders of magnitude stronger than the cosmological constant.

Just started the video, but I think the answer must be “yes?” If you entangle two clocks, then accelerate one, time dilation will occur and they will then have different times, yet still be entangled… just a guess

Is inflation from the virtual particles? What ifbthose virtual particles that pop up in empty space are glued to spactime somehow but also repel eachother. So there would be a constant never ending expansion from virtual particles stretching the space between them as they repel each other.
