What causes anything to have mass?

These days, theoretical physics suggests more and more that phenomena such as mass are caused by abstract relationships we wouldn't necessarily intuitively regard as substantial. In other words, matter isn't what it seems - it would appear that mass, inertia, and gravity along with other forces of the universe are caused by mathematical or informational relationships and that the impression of substance only occurs as a byproduct of our perception.

Mass is the attractive force put on one object by another object. The greater the size and density, the more mass it has.

I hope that answered your question

mass is the amount of matter a body possesses.

Matter is made up of particles such as the atoms

atoms are made of protons and neutrons which constitute the main mass of the atom
