    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.

    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.
