Yes it is true we cannot actually touch anything. It is so because at atomic level there will always be gap between two objects. Like if u r lying on your bed, u r not actually touching it but hovering over it. The electrons of the bed and your body repel each other. We stick to it because of friction or adhesive/cohesive forces but actually do not 'touch'.

Some exceptions:

The only touch with a person we ever had was with our Mom and Dad when we were in the form of zygote.

Also we touch the food and nutrients which get chemically absorbed in our body. Or with some radioactive matter which our body absorbs.

HridayAg0102: I hv made this question myself so I m not sure for its answer
HridayAg0102: but I think it is due to the undiscovered elementary particles
neosingh: basically the concept is hiesenberg ' s uncertainty principle
HridayAg0102: r u sure for it
HridayAg0102: I m not able to get it
neosingh: at quantum level, to detect the exact position u have to put a beam of photons to know the position, these photons have enough energy to excite the particles, so the velocity will change. And if u r able to get the exact velocity u cant know its exact position.
neosingh: i can only relate it to this phenomenon.
HridayAg0102: ok np
HridayAg0102: thank u so much
HridayAg0102: ☺☺
