That's probably a good idea until you learn some basic physics. That way, questions have a chance to be meaningful.
I have only asked ONE question. Why is that question not meaningful? Is the question wrong? Was my understanding about it 27 years ago wrong? You can make it right.
I cannot make it right. Only you can. But it will require some effort on your part, along with approaching it with a bit of humility. Assume you know nothing and start learning first principles.
Start with a good freshman physics text. Work the problems. I use the Feynman Lectures as a basic reference.

I can promise that I will finish the lectures from volume 1 to volume 3. But I'm not sure about working the problems.

Thanks for the recommendation (it must be good if comes from you). His name sounds familiar. I have never memorized names or book authors but my first books on Physics and Chemistry were from McGraw-Hill. Then "University Physics", I think from Young and Freeman. The ones in my current ownership are from publishers endorsed by Cambridge University (incl. CUP). I think I can discard them now. Thanks again.
And forget about my question about gravity contribution on stellar aberration

BTW, SY, do you have online reference or recommendation on source for learning Math? I was reading the Feynman and found "imaginary number" being mentioned. I want to read/refresh with real/imaginary numbers first before proceeding further.
Any high school algebra book will cover complex numbers in detail. Mine was so long ago that it was written in cuneiform on clay tablets.

Okay then. Actually, I have had a plan to read Math for a reason. I have learned quite a lot about Math and little about Physics. But every time my friends (mostly Physics teachers) come to me asking about Physics, I can give satisfying answer/solution. But when people come to me asking about Math, I have to say "Sorry, I have forgotten all". Sometimes I added "It is the most useless subject in the world" 😀 No, no, no, this is not a debate invitation (I know DF will disagree, but I agree with him).
I have learned quite a lot about Math
That's an interesting assertion.
Thanks derF, but I think I will get a text book instead of an online reference.
That's an interesting assertion.
Of course, a lot or a little is subjective (I believe it is less than yours). It is based on how many semesters (I forgot the term for "session") I got the subjects in universities. Besides, long time ago I was a Math teacher (One of my earlier students is now a university professor).
Well, that was a simple one. Recent advances in the accuracy of astronomic observations have demonstrated the importance of taking into account the relativistic effects introduced by the solar system's gravitational environment. I think back in the late 1990's Turyshev at JPL pointed out that the prospect of new high precision measurements with the Space Interferometry Mission would require inclusion of relativistic effects up to third order [(v/c)^3].May be it is better if I just ask questions (Starting with the simple ones). Because you have explained the history of why Relativity theory exist, the question is: "what is the contribution of gravity on stellar aberration?"
The tough question is why you create gibberish about a "true clock" that can avoid time dilation? You've clearly constructed some concept in your mind about an invariant that does't change due to time dilation, but given it the name "clock". You know to tease about stellar aberration and gravitational lensing, but you ignore that the invariant is c, and the english word "clock", which is a measurer of time, is a useless confusion.
I don't understand why so many here don't see through Jay's toying with you. He obviously knows math and physics... actually well enough that he believes his ruminations about relativity and "true clocks" are deep and above you.
Well, I'm not sure if his english is so poor that the joke's on him, or what his idea is.... His last several posts are "playing dumb" to get people here to "offer help", all while he's ROTFL.
Jay, why talk of "clocks" when discussing time dilation? You don't think you're so smart that you're allowed to make up new meanings for old words, do you?

Problem is, you shouldn't mix real variables with "imaginary" variables. But lets forget it.
is a useless confusion.
I know. But you asked, and I answered (I know I shouldn't), and my answer was a big question to you. It's rolling.
Sorry, may be my understanding has been wrong, and I'm making an effort to clarify that (to myself).
In high school, I was debating my Physics teacher that Einstein was wrong with Relativity theory. It looks insane (Me), but I believe that whatever Math or Physics prowess he had, everything should be "logical".
Many years later when we found internet, I tracked the issue to internet, to find if there were others who thought the same. And indeed I found others. They tried to explain everything with Math that was too advanced for me and I gave up...
But the problem was, I didn't know which ones were Einstein's and which were others opinion or interpretation of Einstein's words. I have found that many has misinterpreted Einstein.
Now, I don't know how, but I'm trying to track what have been said by Einstein, but may be I'm not smart enough, I still have a feeling that he was wrong at some points. I'm even doubting that he is as smart as people think he is (But you know, don't you, that it is hard to assess one's intelligence when his is higher than yours).
Sorry if I'm not answering to this.
I know (...) I still have a feeling that he [Einstein] was wrong at some points. I'm even doubting that he [Einstein] is as smart as people think he is (...)
Please stop trolling. You are only making a fool of yourself.
And you are going in circles.
And I'm sorry but you remind of those creationists that would go back to something that Darwin wrote, which is over one and a half centuries old now, and then quote-mine it and then try to refute that and then claim that they have disproven all of evolution.
A lot has changed since Darwin and things also have changed since Einstein.
That whole interpretation stuff is just nonsense, and your doubt of his intelligence is just completely irrelevant.
People here doubt your intelligence. Hope that helps.

Hehehehe 😀 It's something I have no worry about. I'm just trying to be honest and I always am.

Yes, and I was not following. But after reading about quantum computer experiments, I said "what the hell is going on there..."

Of course I'm aware of that (actually no, only after you mentioned it). It has been like that since I was in JH school (that I'm aware of). It hurt at the beginning, and I always tried to prove myself even if i didn't need to, but it was loooong time ago. 🙂
