Gravity can be neither seen nor touched. It is not material.
YOU evos are the ones who have been consistent in telling us that gravity is detected by the effect it has on objects around us. That is not direct detection.
If you step off a bridge, you ignore gravity at your peril.
But you just go ahead and pretend its not there as you do with other scientific evidence.
Gravity is as material as anything is material. It is a form of energy; unless Einstein is wrong, gravity propagates at the speed of light, which makes it a form of energy interchangeable with matter.
