Can you touch fire

Answer 1

Yes, but it would hurt very badly. Fire, like all things, is composed of matter. In fire's case, that matter is called plasma (as opposed to solid, liquid or gas). All matter takes up space and therefore can be touched.

Answer 2

I do not want to give a definite answer, but allow me to tickle your brain. Think of it two ways.

First, light can be the projection of particles moving at the speed of 299,792,458 meters per

second, causing ionisation of the gases and form plasma. Then, we can touch light.

But if you think of light as of a dimension of its own, existing outside the 3-dimensional

Euclidean space, in a dimension where we can only see the light, then we can't touch light.

=======================

Tickle #2:

Shine a flashlight on the wall. See the spot on the wall ?

Now put your other hand in front of the flashlight. What happened to the spot ?

Can you still see it on the wall ? Check the flashlight. Is it still emitting light ? Then

why is the light not reaching the wall ? Is it shining on your hand now ? Did your

hand do something to the light ? Did your hand do something that prevented the

light from coming out of the back of your hand ? Did your hand ABSORB the light ?

And did the energy carried in the light stay in your hand ?

I'd say your hand touched the light, just as surely as the leftover meatloaf

touched the RF radiation in my microwave oven last night.
