What physicists are working towards, although not all of them know it, is that solidity exists only in the fraction of time known as the moment and the moment is real only phenomenologically. You recall your chair as solid throughout the time you have been sitting on it but what you recall are the moments in which it was solid. Its solidity is a bridge to the future which is constantly collapsing just behind the moment and passing into being just ahead of it.
Where is the solidity of your chair a fraction of a second ago? Where is that now? To illustrate this arcing away of reality in all dimensions from the moment or reality coalescing toward it consider the moment represented as a magnet, with the force lines round it as both the decay and coalescence patterns of the phenomenological moment, which know neither past nor future.
Trouble is, you’ll still have to eat and pay bills. Those moments do not arc away. Sleeping rough feels solid all the time.
