Graduate The Pioneer effect and Spacecraft flyby anomaly
Thanks for your responses. I agree with those who pointed out that the Pioneer effect and the spacecraft flybys “mystery” are not clearly understood. They can’t be with our current knowledge of gravitation. I tried to explain the two effects with GRT – no success. I would not trust...- SinghRP

Graduate The Pioneer effect and Spacecraft flyby anomaly
Thank you all for your responses. I agree with bcrowell. 1. Has someone investigated the effect of variations in the Earth's gravitational field or in the classical gravitational constant on the Pioneer effect and/or the Earth spacecraft -flyby effect? 2. Can someone get me in contact with...- SinghRP

Graduate The Pioneer effect and Spacecraft flyby anomaly
This is what I know so far. 1. The Pioneer anomaly is due to thermal (kinetic) effect. Probably heat is from the spacecraft itself. 2. I believe only the NEAR spacecraft to an asteroid showed some significant flyby effect around Earth. At present they have fitted a curve with the data. They...- SinghRP

Graduate The Pioneer effect and Spacecraft flyby anomaly
I will access the link, read, and come back to you. Meanwhile, have you read whether GRT explains either or both? Please be specific; will appreciate it.- SinghRP

Graduate The Pioneer effect and Spacecraft flyby anomaly
Does general relativity explain the Pioneer effect and the spacecraft flyby anomaly? I have seen several papers on those two topics but no GR explanation.- SinghRP

Graduate I know that nothing can exceed the speed of light, but
I just happen to see the original question by student34 at Post 71. Here is one physicist's intuition. 1. I want you to recall Newton's 2nd law: Force vector = Rate of change of momentum vector. If you keep mass and the direction of velocity vector fixed, then force = (Inertial...- SinghRP

Graduate How does matter accelerate in a gravitational field
I read Peterf1's question at Post 2. Does anyone believe this question has been answered? Can anyone answer it without using matn?- SinghRP

Graduate Understanding the Principle of Equivalence: A Closer Look
To stevendaryl at Post 694: The choice of word "equivalent" was unfortunate. As a matter of fact this word is not quite correct in the case of mass either. In the case of mass -- the pseudo gravity field is equal in magnitude but opposite in direction to the acceleration. In the case of electric...- SinghRP

Graduate Understanding the Principle of Equivalence: A Closer Look
As I said before, here is my take on POE-related topics. The principle of equivalence The genesis of the principle of equivalence is in the following equation: (Gravitational mass) ∙ (Gravitational field intensity) = (Inertial mass) ∙ (Acceleration) (1) That is, a mass in...- SinghRP

Graduate Understanding the Principle of Equivalence: A Closer Look
To PeterDonis - After rereading my statement (2) and then reading yours, I think I found the problem. I restate (2) as follows: A mass at rest in a frame is equivalent to being in a "gravitational field" when the frame is acclerating. To PAllen: I will read your post and come back to you after...- SinghRP

Graduate Understanding the Principle of Equivalence: A Closer Look
To PeterDonis: Answer to "What makes you think that? I get lost in mathematical jungle. I am a physicist, and I like to think in terms of physical models. I recall Feynman also: The glory of mathematics is that you don't have to say what you are talking about. The genesis of POE is in...- SinghRP

Graduate Understanding the Principle of Equivalence: A Closer Look
What’s your understanding of the principle of equivalence? In the literature, I find two meanings: (1) Gravitational mass is numerically equal to inertial “mass.” (This is a postulate.) (2) A mass at rest in a frame is equivalent to being in a “gravitational field” in an accelerated frame...- SinghRP

Graduate Is time quantum at the microscopic level?
I have already done an extensive search of the literature. Will do so more. "Genesis" means origin/beginning/creation/... as you said. So, Planck time is a fact! I have come to realize that I am not going to understand gravity without time and its origin. Thank you.- SinghRP

Graduate Is time quantum at the microscopic level?
Time has always baffled me. I have two questions for you. 1. What's the genesis of time? 2. Is time quantum at the microscopic level? Thank you.- SinghRP
