Mass means the number of closed structures.

If some neutron has not any mass, it may be said that the covering of it's formation is not yet closed up. The real reason of mass lies in the only absolute system of ether. Take up the old ether again, then the last flooring of understanding shall be concluded. The ether has his center, and if he is right-handed, he cannot be lef-thanded. He has his face and back, his head and foot, and his right and left. The only universe is knitted with this six-bearing characteristic.
