    Van Flandern's paper on "Speed of Gravity", question.

    Lol. I kinda figured he might have been from his biography. But it is true that his paper heats up the imagination of non well informed readers (like me). After reading the link above and regurgitating it on my pillow I re-realized (duh ^_^) exactly what you just said, the apparent movement of...

    That was great. Thanks!

    Van Flandern's paper on "Speed of Gravity", question.

    Hello, I just recently came across this paper and I've been since reading everything I can find about Van Flandern's "credibility" and the controversies his proposals brought up. Still I'm yet unable to find a source to verify or disprove this assertion Van Flandern makes in his paper: "How...

    Pair production: Has it been observed experimentally?

    Ok. So I take that pair production can be obtained just from photons and no nucleus is required.

    Pair production: Has it been observed experimentally?

    I was reading about electron-positron annihilation and I got to the part where it says that this is a reversible process, meaning that an electron and a positron could be created from photons. About this reverse process the article says "In nuclear physics, this occurs when a high-energy photon...

    Are acceleration and gravity completely equivalent?

    That's simple enough. Then I guess that's where the analogy ends. Given enough gravity, you can make a finite amount of mass infinitely dense. No other force in the universe, SFWK, can accelerate (compress) mass that way.

    Are acceleration and gravity completely equivalent?

    Someone suggested that in a thread at gamedev.net yes, it did cross my mind but I'm actually more interested in trying to understand why is it impossible to accelerate an object until it has "black hole" amount of density but black holes themselves with infinite density (?) are considered to be...

    Are acceleration and gravity completely equivalent?

    Maybe tidal gravity could be analogous to acceleration caused by centrifugal force. Still, to the effect of making a body with mass infinitely dense by the means of acceleration it'd be required infinite amounts of energy isn't? Does this also applies to acceleration by gravity?

    Are acceleration and gravity completely equivalent?

    Hi, thanks for the welcome and the replies. Oh I forgot about this yes. I understand that the black holes gets formed from a finite amount of mass. What I find hard to understand is how it gets to get as dense as to being able to accelerate light "backwards" or at least cancel out light's...

    Are acceleration and gravity completely equivalent?

    Hello everyone, I just mailed this question to NASA's Cosmicopia but I'm afraid they might not be able to reply. So I registered in these forums to see if maybe someone can give some guidance. So here it is: We know that accelerating a body with mass to the speed of light requires...
