Gravitational Redshift Test Using Eccentric Galileo Satellites:
Disclaimer: It is arguable what is THE best test of general relativity because there are different ways to test the theory. This is the best confirmation of gravitational redshift, which is one of the three original tests proposed by Einstein.

have they tested the atomic clock (based on matter decay) in orbit (no gravity) compared to the atomic clock on earth (gravity on each atoms) or the relativity theorie itself? I doubt about Einstein theories since I read the report from the fraud of the 1919 sun eclipse measurements of light bending (without taking refraction in account and modification of the equations))

Question of a noob here: since spacetime is warped by mass and time runs slower closer to the mass, I wonder: if you made a clock on earth f.e. and get closer to a black hole f.e., you would see no difference. But what if you would just send the clock, and compare it with an other identical clock on earth? So you would be an external observer. Would it appear to tick slower since spacetime is warped and it behaves according to ‘that’ spacetime? Or would it appear to tick faster relative to the earth’s clock, since spacetime is warped but it follows the time on earth?

I've read in many places black holes occur because very large masses are pressed into infinitely small space like in the cores of giant stars. So I assumed it's going to be small (this is where must've been wrong). But later I learned they are some of the biggest things in galaxies. Is it still small in the center with a big-ass event horizon or is it really that big comprised of these infinitessimally small but compact holes?
Gummiel 7 dagar sedan
Kinda both, as far as we know (the exact details of black holes is not that well understood, compared to many other things), it is kinda both, they are extremely small but extremely dense. This extreme denseness creates a rather big area around it of which nothing (not even light) can escape, and well the boundary of this area is what is known as the event horizon

That's the problem with having more and more accurate theories. It becomes A LOT harder to disprove them. Entertain the idea for a moment that it isn't possible to write a complete unified field theory of physics (just like some equations have no closed form solutions), and it is only possible to make closer and closer approximations to nature. Maybe God does have a sense of humor.
Des Troya
Des Troya Månad sedan
I don't believe Einstein's theories are accurate. They explain several things, but they break in a few important cases. For example, when near Earth, the idea of curved "space-time" pushing us towards Earth is nonsensical, while Newton's model works physically and mathematically. Secondly the idea of some "space-time" matrix has no physical justification. We have no characterization of space-time as a physical object and how it acts on physical objects in Einstein's theory. It is a specter, a ghost in an otherwise physical world. Therefore it is questionable whether that is actually the mechanism producing time dilation and gravitational rotations at all.

G rel is just the mathematical representation of a real classical physics phenomenon. The MM experiment is flawed because the unscientific 'assumption' that mirrors reflect at c was made. False. Mirrors absorb and re-emit light at C+V and C-V with V being the velocity of the object through the universe. That's called light speed anisotropy and acellerative reference frames are not a problem with that physics. Looking for an ether was misguided. There is no ether or rather it is a universal reference frame that allows galaxies to travel faster than C at the edge of the universe. This also allows for the speed of say earth through space to not be measurable by the MM experiment. However light in fibres and radio waves in coaxial cables do show anisotropy. Maxwell made a mistake when he assumed that charge flows instantaneously onto a plate when charging it. This is the first falsity that ~even though Maxwell still calculated c~ resulted in Lorentz etc. Maxwell's charge actually travels to the plate at c like all good electrons in an electrical circuit do. Maxwell's experiment was being carried out on an earth travelling at great speed through the universe and he still arrived at c. That seemed strange to Lorentz et al which led to further thought regarding moving objects and the speed of light. Having said that Lorentz was wrong in his reasoning about charges needing to travel instantaneously, or else an atom at high speed would leave them behind unless they could somehow orbit faster than c. However by some good fortune his math resulted in the relativities which are fair analogues of the classical physics involved so there is no reason to redo physics at all. Just be aware that the mathematics is not causality. That would be rather foolish right? I have actually readdressed the physics in a 1300 page tome but It is of no use. Electrodynamics and chemistry along with general engineering seem to have got everything in order so we might as well leave it at that. Who needs to know how the universe works without dark matter and with multi-dimensions in any case? I have most of the answers but it will die with me.

I love this mentality that for a real scientist, finding by the experience that a result is predicted and became predictable by a theory is disapointed because you failed to find the issues ou this theory. Maybe Pecome Belva said "unfortunatly" because this experiment would have make him the one that found the issues to the Einstein general relativity and it would have propulse his career at the top if the tests had shown that it had some but I prefer to think that it was a professionnal scientist that prefer proceeding by elimination than constantly confirming their beliefs

But, if the signal from the satellite itself has to cross the area of change in gravity (gravity gradient?) on its way to be measured by earth instruments, is there not some effect on whether the earth based clock and satellite clock sync up? That is, would the _change_ in the relativistic effects not also affect the signal as it travels, as well as the clock themselves, preventing you from making a side-by-side comparison?
Hayden Tyler
Hayden Tyler Månad sedan
The change in gravity is actually what causes the time "change". If you imagine sheet with a grid covering it and you put a heavy ball on the sheet, it will push the sheet down and stretch the squares on the grid. In the real world, the same thing happens. The earth bends space with it's gravity. If you produce a frequency on the unstreched squares, where the tops of each wave is 1 square apart, when it travels to earth, the space will stretch and the tops will be 2 squares apart, called redshifting

Question, does the clock really physically tick slower? I always thought that time slowed down, but because clocks are human-made and just displaying time at the same speed I expected them to keep ticking the same speed as when they started, no matter the gravitational pull. The other side: If the clock keeps going the same speed as it does on earth, and you go near for example a black hole, where time slows down, would we see the clock tick faster? I need answers
Hayden Tyler

Cyberwizard Productions
Cyberwizard Productions Månad sedan
so I have an idea - let's test this with something that measures the passage of time that isnt' affected by gravity itself. Just because a clock ticks faster doesn't mean time is actually passing faster, it just means the clock's mechanism is speeding up - or slowing down - and the clock is becoming inaccurate.
Hayden Tyler
Hayden Tyler Månad sedan
This is all relative. That is why it is called relativity. To the people on Earth, time is litterally at a different speed. For the sake of simplicity, I will make up simple numbers. Say there are two astronaughts. One on Earth and the Other on the sattelite. After 50 years on Earth, the person in the sattelite will be younger than the person on Earth, and would not even say they were up there for 50 years. They would say they were up there, say, 40 years.

​@Hayden Tyler : There are several recognized Quantum Theories e.g., Copenhagen Theory or Many Worlds Theory or Transactional Theory or Stochastic Theory..... Einsteins General Theory of Relativity is supposedly THE gravitational theory but it has flaws. The problem with quantum mechanics in a nutshell is that it actually tries to use a Newtonian integral to define a point and that's why it returns this probability nonsense. There is one simple equation and theory that ties all the forces and theories together and that is Euler's formula, and yes Euler's formula is the wavefunction, Psi.

Or the wave pressure in the quantum membrane in the "rosebud", where the transfer of wave energy during the drift of the center in the "rosebud" is possible through the quantum of the string. Quantum entanglement is a mixed transmission of information without intermediaries through the quantum of strings and with intermediaries in fractals from the quantum of "rosebuds".
