The last time I looked, it was considered something like acceleration, but I can't imagine how that could work, even considering additional dimensions and the suspension of time at a black hole. Can you?
It is helpful to me to think about gravity as being something that deforms the space around some kind of object and causes smaller objects to “roll” towards the indentation of space around that object, or actually roll into the “hole” created by a Black Hole.
I think the acceleration comparison was created by Einstein.
It is certainly an interesting and apt comparison, but it has never helped me to visualize what gravity is.
Curiously, gravity can signal the presence of a neutrino, but the signal is so small it is almost impossible to detect it with current instruments.
From memory, they currently detect neutrinos from the flash of light created when a neutrino strikes an electron.
Hope this helps.
