    I Is gravity action at a distance or is it a local force?

    This response is mind-blowingly comprehensive. Thank you so much for putting in the time and effort. I'm not a physicist but I am curious at a level that far exceeds my grasp. I have a few observations/questions that I'd appreciate some clarification on. Okay, it's not a few, and it's not all...

    B Conflict Between Time Dilation and Red/Blue Shift?

    So next time I make a similar post, how should I categorize it? I've got another burning question about black holes.

    B Conflict Between Time Dilation and Red/Blue Shift?

    DOH! Umatrix had disabled javascript. Thanks, fixed. Much nicer. Time to re-read the thread. I'm using umatrix with Firefox to speed up page loading and prevent tracking/hacking since Linux desktop doesn't have much available in antivirus/antispyware FOSS (that I am aware of anyway). I only...

    B Conflict Between Time Dilation and Red/Blue Shift?

    Thanks, downloaded. I don't have the maths any more, but my ambition is to recoup that skill eventually. I still have good grasp of the concepts, at least those I did well on originally. I'm also interested in string theory, so any similar text on quantum mechanics would be equally appreciated.

    B Conflict Between Time Dilation and Red/Blue Shift?

    Where I'm having immediate difficulty with the math is in interpreting the editor's mathematical notation. Bear with me, for a former engineer I'm sort of a Luddite by virtue of economic necessity. The code is rendering as code rather than notation in my FOSS Ubuntu 20.04 with Firefox and...

    B Conflict Between Time Dilation and Red/Blue Shift?

    Actually I was grateful for the elaboration even if I'm not up to the math. I'm in a sticky position where my curiosity exceeds my grasp. Maybe if I keep on posting I'll get a better feel for this and generate less confusion. My first post was a total bomb that got deleted in moderation. I'll...

    B Conflict Between Time Dilation and Red/Blue Shift?

    Claryfying: This question isn't intended for the brainiacs, though they are welcome to strut their stuff! I'm trying to clarify my hand-waving understanding of relativity by asking basic questions. I think I've identified the source of my confusion in the concept of inertial reference frame, so...

    B Conflict Between Time Dilation and Red/Blue Shift?

    Experiment 1: Astronaut travels away from Earth at near the speed of light, then travels toward the Earth at near the speed of light. Einstein tells us she barely aged, but red shift/blue shift don't seem to agree with that. While traveling away, both Earth and astronaut observe each other...

    Trying to decide which programming language I want to learn

    What you should use is mostly dependent on what you want to do with it. One caveat about C languages is that the syntax can get really cryptic and it's so flexible there's a dozen ways to do every task with some far more appropriate than others, so I'd recommend liberally commenting your code...

    NASA Why isn't NASA using artificial gravity for manned space travel?

    I think the larger question is where are we going with the space program? It seems that colonizing Mars is out of the question and we've got global warming plus pandemic here on Earth. AG in space seems like a purely hypothetical topic. I'm more concerned about preserving civilization now than...

    NASA Why isn't NASA using artificial gravity for manned space travel?

    The machine guns, shrapnel, and radiation experiments were a far larger problem than AG for the crew of the Roci. Oh yes the political instability was also an issue. lol
