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.
The acceleration bit confuses me, but I can understand how, as you say, objects "roll" towards the indentation of space around an object.
Do you understand how that could cause a wormhole and shorten the vast distances? I don't.
Thanks! I really appreciate your help in understanding these things.
