  1. Simon; 1. So is there any chance a electron jumping into another nucleus? 2. Gravity influencing clock rate is much different with influencing time. 1. The atoms are cooled to low temperatures for more control, a typical precaution in isolated experiments. 2. Both factors reduce the available energy of a clock. You can visit Nist.gov for official answers, they provide the world time standard.
  2. Simon; A small amount of cesium is in a gaseous state, and manipulated with lasers as it falls vertically. A microwave generator flips the spins of the electrons, then a laser energizes the electrons and a detector counts the number that flipped to higher energy states. The feedback from the detector adjusts the microwave frequency to be resonant with the cesium atoms transition state, approx. 9 billion hertz. The waves may be considered a photon. Density does not play a role in atomic clocks.Motion affects clock rates, since motion alters em processes. Thus time dilation is a consequ
  3. Are you aware of Lake Vostok below the ice in Antartica, that has more meaning to us?
  4. If we imagine the 14 billion yr history since the 'big bang' as a movie, then we are expected to believe that walking in near the end and watching the last 4 milliseconds, will enable us to reconstruct the story! Who would have thunk it. That's why I ignore any long term predictions!
  5. You used the important term 'trust'. The 'experts' in their field, trust the educational system that taught them, and believe they are passing on truth, as best they know it, at the present.A patient seeks a diagnosis from a doctor who is more knowledgeable and experienced than the patient. A person takes a flight to a distant place, trusting in the experience of the pilot, traffic controllers, maintenance people, etc. No one can do all things necessary in life, so they must depend on others.Unless a person is deceitful or dishonest, they will provide the best service they can.The one cri
  6. Most people who spend time and money in the pursuit of education want to believe they have acquired knowledge that helps them understand the world they inhabit. They trust in the scientific method to find answers to their questions. Their confidence is enough to publish information to others, and the public is expecting 'expert' opinions. Now imagine an aircraft crash scene. Investigators arrive to reconstruct the event.That is similar to the state of human knowledge. The world was already here when humans arrived. They must hypothesize or speculate with whatever evidence they can find as to h
  7. Same answer to your previous questions. 'They' are speculating based on what little knowledge they have. They are making it up as they go, revising their thinking as knowledge increases.
  8. Simon; [Yes. If experiments involving light transmission didn't work because of issues with direction, it would have been discovered long ago. I'm giving a logical explanation since you are hesitant to trust an answer based on theory. R. Feynman's "QED" with its experimental verification, supports the photon model of light (vs the wave model), and explains most light phenomena, reflection, diffraction, etc. very accurately. Go [here] for a list of experimental verification (facts) of SR.] [If the MM experiment is considered a two clock experiment, one with vertical o
  9. Simon; In making any device, there is never any concern regarding motion of the Earth surface or Earth motion in space. If you build a light clock (your primitive device) in the summer time, it continues to work even though Earth is constantly changing direction. So from experience, processes work the same in any ref. frame that is moving at a uniform velocity (constant speed, constant direction), which is postulate 1 in SR. The curvature of Earth orbit is not a significant factor for processes with short cycles. Your device works independently of direction/orientation. If ab
  10. Marcos; Presenting more experimental evidence won't help, since you have decided beforehand that it's false based on your preconceived notions. I watched the video you cited. Poor quality, a show & tell, where the person learned a new word 'gamma'. He used it repeatedly, and conveyed nothing.
  11. Marcos; Which part of this diagram shows any inertial frames of reference? Which part of an airplane flight is inertial? None are, so any math used to calculate imaginary time dilation would need to NOT simple be the math of Lorentz which is ONLY valid for pure inertial frames. Yet that's what they used, the wrong equations. In this diagram, which of the clocks on planes G and E would lose time and which would gain time? They both would experience time dilation, none could possibly experience negative time dilation, yet that's what they claimed. Clearly they were l
  12. Marcos; Sorry for my lack of focus. In the HK experiment, there are other ways to represent it, especially since it involves absolute motion, rotation in 2 dimensions. There is no reciprocal td. The view is from above the South pole, showing the clocks varying speed of rotations relative to the earth center, and why the center is the common origin for this case. Since the earth radius R is 6400km, the aircraft paths would be very near the surface, and are shown at exaggerated heights for comparison. The speeds in km for W, G, and E would be 800, 1600, and 2400 respec
  13. Marcos; [Each plane flew a circle slightly larger than that of the ground clock for approx.48 hrs. That is a distance.!] BUT also this applies for the Velocity v. We must have to distinct variables as they are not the same! We must have v and v’. [How can there simultaneously be two different rates of separation for two observers moving past each other???] You're not there yet. On the left, your example: U the ref. frame, A with v=.2, and K with v=.5. The event is (K at 500). Coordinates for K, U(500, 1000) Coordinates for A, U(200, 1000) A c
  14. Marcos; After reading 'Did H and K prove Einstein wrong': The actual result was that the westward travelled clock increased in its time rate (more time had elapsed) and the eastward travelled clock decreased in its time rate. [All clocks lost time. The west clock lost less than the ground clock which lost less than the east clock. 1) Inertial motion can only be referenced to the physically privileged frame of the “universe” which is an absolute inertial system. [There is no absolute rest frame in Special Relativity.] Surprisingly, only when the train travels due
  15. Marcos; I checked out the Khan site and it's not very good. Cluttered with too much stuff, a pointer and narration that's too fast to follow. No surprise it's confusing. Here is summation of results from the HK experiment. Notice, there are both types of time dilation. Included a reprint of the original article. Around-the-World Atomic Clocks In October 1971, Hafele and Keating flew cesium beam atomic clocks around the world twice on regularly scheduled commercial airline flights, once to the East and once to
