Everything has gravity with respect to all other objects.?ÿ Size and distance are the elements that combine to make it noticeable.?ÿ The Sun's gravitational pull is what keeps the solar system intact.?ÿ Earth's gravitational pull is what keeps us from floating off into the Sun.?ÿ My body's gravitational pull is responsible for the attraction of grit and grime. ???? ???? ?????ÿ
That's kind of what's fun this post I was having a discussion with a physicist friend of mine about the speed of light and being a constant and then when it approaches a dense highly gravitational place like a black hole does it actually accelerate with some proximity to not get sucked in.

It is I'm typing this I'm driving past the New Mexico tech University and just to the west of there in the Magdalena mountains in Lang near research facility that has an interstellar interferometer
@brad-ott Funny. I just had this conversation with myself earlier this week during the brief instant I was suspended in mid air after the 8' ladder I was on top of kicked out from under me. Time became compressed as gravity suggested I slam flat on my back onto the ground, at which point I saw the light of many stars. My bruised kidney and ribs suggest that I lost that argument.
Just because I'm paranoid, doesn't mean they aren't out to get me.
Dark humor is like food; some don't get it...
I'm pretty sure that as the velocity of an object approaches the speed of light it can outrun gravity.?ÿ I discovered this by actual physical observation.
I was in bed once with a young girl when her hulking boyfriend came home early.?ÿ I approached the speed of light as I exited the premise.?ÿ I definitely outran gravity because I don't remember my feet even touching the floor.
@jitterboogie Well if it truly is a constant you would be able to view?ÿ a Supernova multiple times due to gravitational lensing of galaxies between the supernova and earth. Yet if gravity does affect light as all other objects, why does it not produce a slingshot effect on light the same way we use it to speed up our space satellites?

@paden-cash :?ÿ Were you the guy almost caught by the jealous husband when the cheating wife said, "Quick,?ÿ jump out the window, it's my husband!"?ÿ The interloper said "...but we're on the thirteenth floor!"?ÿ And the cheating wife said, "This is no time to be superstitous!"
Once in the throws of passion I heard a car door slam.?ÿ I jumped up and had my britches half on when I realized it was my own house and I was with my wife.
...but what bothered me was the fact that when the car door slammed my wife hollered, "Oh my God, it's my husband!"?ÿ 😉
This is a silly discussion, we all know that the Javad is faster than light.?ÿ
@mathteacher Oh man, that's heavy....
My son (BS in physics, currently a PhD candidate in mechanical engineering) once explained to me how entanglement doesn't involve communication between the particles, but like many of his explanations it went way over my head.
"He could turn of the lights, and get under the covers before the room got dark!"
Knew a fellow who reportedly spent the night under his sweetie's bed because her husband came home and that was the only place to hide.?ÿ He had to stay awake because he was a snorer.?ÿ Then had to stay hidden until he was given the all clear from his now-ex-sweetie after the husband left for work.?ÿ The worst part though was the husband was a big ol' boy and had come home very horny.?ÿ Kerwhumpa kerwhumpa kerwhumpa kerwhumpa ker.......................................................
I must say I am getting a good laugh out of some of these post(they are very good).
As for gravity; In Einstein's General Relativity "gravitation is propagated with the speed of light" (page 94 of space, time and gravitation by Sir Authur Eddington, Harper Torchbooks 1959.
In "Theory of Relativity by Wolfgang Pauli (who got his P.h.d at 21 years old) on page 173, equation 443, "It?ÿ can be seen that the gravitational effects are propagated with the velocity of light" ; Pergamon Press 1958 (the year that Pauli died). Very Mathematical for those that like to see all the math( MathTeacher).
One last thing is a nice relativistic limerick (about light) from the book One two three... infinity By George Gamow, Viking Press 1948, page 102;
"There was a young girl named Miss Bright,
Who could travel much faster than light.
She departed one day,
In an Einsteinian way,
And came back on the previous night."

My YouTube University education is ??c?? is the maximum speed limit of the Universe. Light travels at ??c?? in a vacuum because photons have no mass.
The velocity of everything in the universe varies with the position and motion of the observer except light which travels at ??c?? as seen by all observers. Therefore if light is emitted by a traveling object time must slow down so that light does not exceed ??c.??
It Is said a Soviet cosmonaut orbited Earth so many times at such a velocity that he traveled forward in time a measurable fraction of a second.
