How “bound together” is our Universe?

Our Universe’s matter, fundamentally, is composed of elementary particles. <img alt="" src="https://miro.medium.com/v2/resize:fit:630/0*RnJAtKwI7HyqxXXG" style="height:394px; width:700px" /> On the right, the gauge bosons, which mediate the three fundamental quantum forces of our Universe, are illustrated. There is only one photon to mediate the electromagnetic force, there are three bosons mediating the weak force, and eight mediating the strong force. This suggests that the Standard Model is a combination of three groups: U(1), SU(2), and SU(3). (<a href="https://home.cern/science/physics/standard-model" rel="noopener ugc nofollow" target="_blank">Credit</a>: Daniel Domingues/CERN) <a href="https://medium.com/starts-with-a-bang/how-bound-together-is-our-universe-7b6ab1ac8cdf">Visit Now</a>
