Physics predicts all of Cosmic Time. Here's how.
Believe it not, Einstein originally thought the universe was static. It would take Alexander Friedmann to correct him. Here are the Friedmann equations, explained simply.

    • @ScienceAsylum
      @ScienceAsylum 6 годин тому

      Different planets have different time gradients. When objects fall, they're just following a special path in spacetime called a geodesic. What we measure as "weight" is just what we see when something like the ground or floor prevents the falling object from continuing to fall. A force is required to keep the object stationary.

    Something I don't get though, is to say that quantum superposition is in someway 'intrinsic' to atomic and subatomic particles. If we say "there's 30% probability it will be A and 70% probability it will be B"... Might there not be a reason WHY it is A or B which we are simply unaware of? It just doesn't seem very scientifc to me to simply say something like "it might rain, it might not rain.. but it will probably rain (although yes of course, with concrete and real probabilities and not figurative ones)" My doubt is summed up in that phrase that goes "randomness is ignorance of forces unknown to us" or the like Please enlighten me

    Very interesting video! Don't you support Feynman's ideas? I do. I also don't think the superposition state and wave convergence are correct. The Copenhagen interpretation combines Einstein's idea of ​​wave packets with Max Born's probability interpretatio. But waves do not exist. Only Max Born's probability interpretation is correct. If the superposition state is incorrect, there is nothing mysterious. ● Regarding Schrödinger's cat experiment, Schrödinger is correct. ● There is no need to consider quantum teleportation. Please continue to share your thoughts in your videos. I wish you the best of luck.

  • @likithstochastic
    @likithstochastic День тому

    Nice description. Identifying the second derivative as the curvature and distinguishing its behavior in one equation from the other is particularly insightful. This intuition beautifully agrees with the solution of the 1-D diffusion equation, where the two curvatures of opposite signs (one at the head and two at the tails) cause the head of the gaussian function to come down with time, while its tails grow in height. When I first understood the diffusion equation during my early days of learning, it gave me a better physical insight into the dynamics of the Schrödinger equation. I feel it's always nicer to view the Schrödinger equation as a form of diffusion equation describing a complex function, which interestingly gets called as the 'wave function'.

      All energy contributions are in the energy density term. That being said "magnetism" isn't really an individual thing you can put in the Friedman Equations. If you have magnets floating around then you probably don't have a uniform energy distribution, which is required for the equations to be applicable. Electromagnetic radiation, however, can be put into the equations.

    I don't know if you are still reading these comments, but I was just watching the Richard Feynman lecture from the University of Aukland. I believe the lecture series was titled "Today's Answers to Newton's Queries about Light." In that he described the "wave-particle" duality as a state of confusion before people knew what was going on. But he quickly followed up by emphatically stating that light (and other such tiny building blocks) are particles. Very emphatic in that. But you are saying even more emphatically that they are waves. Can you help me understand? My understanding is that they are particles, but the differential equations that govern their motion are not analogous to those of classical mechanics. These particles move probabilistically, and you compute probabilities by summing/integrating the probability amplitudes for any possible path, then taking the conjugate-square of that result. The probability amplitudes, I believe, are computed by what we call the "wave function," but in another video I think you did a good job explaining that this first-order differential equation was more akin to a heat flow differential equation rather than a second-order vibrating string equation.

    • @ScienceAsylum

      Photons (and electrons etc.) are neither particles nor waves, at least not in the _common_ use of those words. Quantum "particles" have behavior much closer to waves, but they're not really wave either. This newer video might help: ua-cam.com/video/zS2vI_2faII/v-deo.html

    Both light and electromagnetic waves are called waves. Is the wave going out from point A to point B? Or is it already at points A and B like the sea, but only the waves are transmitted? In modern science, it seems to be seen as the former... / What about time and space? In modern science, time and space are the latter, don't you think? / In other words, space-time comes first, and light, photons and protons go along that path... / So the Einsteinian school's absolute speed of light is strange? At the absolute speed of light, is not the speed determined by light, but by the time and space that already exists? Isn't speed the time to move from point A to point B? If time and space are not absolutely fixed, why does the speed of light have absolute speed? / Therefore, the absolute speed of light can also be wrong. Isn't the absolute speed of light a space-time dimensional barrier? If it exceeds the absolute speed, will it jump to another dimension? / Einstein's theory is based on the dimension only now, so if you go beyond this dimension, is not it beyond the constraints of Einstein? / The question is whether you can find an object faster than light or accelerate light. Or is space-time and massive mass spread out in front of us, and can not we cross the space-time dimension using space-time and massive mass? / In this sense, I think we should study whether there is a way to send signals to the past. You don't have to worry about who in the past will get this signal, do you? We're already receiving a 24-hour signal from radio telescopes and various receivers.

      If we go deeper... Light has a slower speed as it passes through the medium. / It is not that we can not accelerate light, but is not the absolute speed of light the highest speed of light observed in our dimension? / Is not it observable only at a constant speed in the dimension we are in? / If we accelerated the light at all, for example, if we shot light on a spacecraft, or if the light of the sun already moving at a high speed exceeded the observable absolute speed, would not it have passed to another dimension? / Whether there are eleven dimensions, or even larger dimensions, is not there necessarily a overlap with our dimension in the end? / Would not light or radio waves that went to another dimension come back to our dimension as slow as passing through the medium? / Can't we do an experiment like this?

    I got six, I got eight, on fifteen I guessed eleven and then reguessed 15 before the answer was given. I don't actually recall seeing the flash for 23 the first time before hearing the answer, and with 57 the answer followed up so quick that I wasn't able to think any words before it was provided.

    The hottest possible temperature is called: Planck temperature

    Three years forward and Many Worlds interpretation is more or less out of fashion... and almost every UA-cam-commenting physicist is criticizing and dissing it (for the same reasons as shown in the video). And some of them started pointing towards Superdeterminism - interpretation that has locality, causality, and determinism but with hidden variables??? - (i think so, not really sure)

    I think you should picture the unconvential spacetime diagram as 3 dimensions: 2 for space and 1 for time

    You forgot m type brown dwarfs. M type brown dwarfs are red dwarfs have spectral type M5.5 or later

    My plan is to make a solar system model. The scale is 150 million to 1. This means 1 au equals 1 km in that scale

    If you see green or purple stars, it could means that star is redshifted or blueshifted, it could means a comet or asteroid or a planet

    Fun fact: The hottest possible temperature, the planck temperature, is where the wavelength emitted by the black-body reaches the planck length

    Parabolic and hyperbolic paths are called trajectory instead of orbits because they aren’t bound

    If you know all laws of physics maybe. Truthfully scientists don't know how the 4 fundamental forces are formed or where they come from . Just so many topics with holes of data missing. So why do scientists think they are going to figure out the entire universe in a little equation of a couple inches long. Wishful thinking and the reason it hasn't happened
