One way to see the table is as disturbances in an underlying quantum field. The field curls and kinks and we see this disturbances as particles at the atomic scale and as solid matter at the macro scale.
Does it support my glass?
From the quantum field perspective there is no mass, no matter, no table. The various fermions we perceive as particles are peturbations in the quantum field rather than 'solid things' and the way they interact is by exchange of bosons which are themselves fields with excitations or peturbations which correspond to the 'particle' nature of the photon (or hypothetical graviton).
Can I put my feet up on it?
Sooo....at a very basic level there is no table. The table is percieved as such because the quantum field excitations which we think of as 'ourself' interacts with the quantum field excitations which we think of as 'the table' in a predictable manner to produce certain outcomes which we label a table.
Not true. I can put my feet up on it and still reach my glass. Therefore it exists.
Anyone so limited that they can only spell a word one way is severely handicapped!
