... watch them fall together. Guaranteed to be the most interesting 4:41 of your day, if you like science.

Einstein using his theory of general relativity would say: The reason the bowling ball and the feather fall together is because they’re not falling. They’re standing still.
There is no force acting on them at all.

Bollocks. Gravity is acting on both of them.
 
Don't shoot the messenger. Just relaying what Einstein said.

ETA: Pretty freeking cool video

Thanks for posting that video.

That should be considered a mined quote for two reasons:
1) You left out the part, "If there were no backdrop to give perspective, it would seem like the objects fall together because they are not falling, they are standing still."
However there is a background to give perspective ant both the bowling ball and the feathers are in motion relative to that.
2) The obviously longer video was cut off at that point.

It is true that Einstein rejected the Newtonian idea of gravity in favor of the concept of a four dimensional "space-time" which is deformed by mass.
 
Gravity isn't a force, according to Einstein.

Yeah, Albert could never make gravity work with general relativity. Then again, the the quantum boys can't make it work with the Standard Model either.
 
Everything is relative. If it is true the bowling ball and feathers in the video are falling toward the Earth, it is also true the Earth is falling toward them. But then we get into which falls furthest, of course.

Yeah, and no "graviton" has ever been found, nor have any gravity waves ever been detected.

It is possible that the perception of gravity is an illusion created by deformations in space-time.

The universe appears to be comprised of 2 forces that resist each other. Expansion and collapse.
Pull a dish rag at its edges. You can't pull it apart using all your might because it's held together by the fabric in its makeup. Just as the universe appears to be held together by its fabric. The more we learn about dark matter and its relationship with matter, I think the more understanding we'll have as to what gravity actually is along with other breathtaking discoveries. We may not see it in our lifetime, but who knows?

Do you have any relevant articles to cite which supports this idea or is this something out of your own head, or are you rephrasing an analogy made by an astrophysicist attempting to explain a concept to a lay audience?
