Standard Model of Particle Physics Explains Everything Except THIS (2018x43)

Standard Model of particle physics, Explained simply. The structure of matter, that is, everything you see in the universe – you, me, the earth, stars happens to be made up of some core fundamental particles which are governed by four fundamental forces. Our best understanding of these fundamental particles and forces, is represented by the standard model of particle physics.
It is a stunning piece of work which explains nearly everything, But it has a gaping flaw, because it does not explain something that is fundamental to our existence. Not only that, it also happens to predict that our universe should NOT exist at all.
The standard model consists of 12 elementary particles known as fermions. The fermions are 6 quarks and 6 leptons. All non-fundamental particles like protons and neutrons are made of these elementary particles.
The guage bosons are force carriers and are responsible for three fundamental forces of nature. Gluons mediate the strong force which binds the nucleus of an atom. W and Z bosons mediate the weak force which is responsible for radioactive decay. Photons mediates the electromagnetic force which causes light and magnetism. And the Higgs Bosons gives all fundamental particles their mass by interacting with them.
And how do the forces manifest themselves?...it happens through the exchange of the guage bosons.So for example, if you bring two magnets together, the force is actually being manifested because of an exchange of photons between the positive and negative poles. You can’t see the with the naked eye, but they are there. Similarly the other guage bosons are being exchanged for the other forces.
Where is gravity? It is nowhere to be found. This is pretty important, because of course, without gravity, the universe, and we would not exist. So as impressive as the standard model is, it does not explain gravity.
All we have to do is find a new gauge particle called the “Graviton” – then we will have a model that e
