I don't know that we can make that assessment based on the image alone. After all, the curvature of space time around the BH is so immense that light from the top and bottom sides of the part of the disk that resides behind the BH (light that would normally be eclipsed by said celestial body...

my mistake...i didn't realize that the OP was looking for a point or region in which gravitational forces cancel completely. I guess I need to read more carefully first, b/c after having read the OP again, a stationary floor and ceiling scenario doesn't exactly work like actual orbiting...

"Lagrange point" or " Lagrangian point" is the term you're looking for...

this one gets my vote too.the way i got started myself though was in a Barnes & Noble. i stumbled across one of those large "picture & explanation box" coffee table astronomy books on the bargain rack, so i bought it...specifically, it was Universe by Robert Dinwiddie. it was the pictures and...

well think about it...the engine provides power to the prop, not the wheels. its the prop in conjunction with the air that propels the plane forward via Newton's 3rd law, not the wheels in conjunction with the ground. so why would we have any reason to believe that the plane would not move...

quite right...i should have been more specific in my description and said that the vibrations are approximately uniform such that the ripples on the surface of the water approximately represent concentric circles. surely there is some flex and deformation in the bottom of the cup as it...

notice in the video that the cup does not slide smoothly across the surface of the table. the cup is sticking to the table, then losing its grip, and then sticking again after having moved a certain distance...and this process keeps repeating itself so long as someone or something applies a...

your claim is still false. just b/c a rod or some other object rotates about an arbitrary point doesn't mean that the point rotates with it. it simply cannot be proven. take a circle in a 2-dimensional space and rotate it an arbitrary number of degrees/radians. the reason we "know" the...

nice shots of M3 and M42 guys!

while the fact that Pluto's orbital plane lies outside the ecliptic does make it unique with respect to the planets, the rest of what you said here isn't quite true. Pluto's orbital path doesn't literally have to cross that of Neptune's in order to influence it gravitationally. they simply...

i think i completely understand your explanation, but i also think one needs to be very careful with the wording when discussing motion, relativistic or not. to say that the front of the rocket will have moved away from the rear implies that the rocket is in fact stretching in length. if...

HAAAAAhahahahaha...crack pottery at its finest!

no, this is not true...but it is true that a smaller mass can be accelerated up to a specific velocity quicker than a larger mass accelerated to the same specific velocity. likewise, if two different masses are accelerated up to the same specific velocity in the same amount of time, the smaller...

...and tens, maybe hundreds of thousands of stars!

very nice ^...equipment?
