Impacts and Forces
Many objects in space do collide, even when equilibrium is reached in the system. There are a lot of threats of asteroids on Earth but what makes them so deadly? Surprisingly, it is not the size of the asteroid, but the energy it has, mainly kinetic energy. Let's say that an asteroid the size of the the statue of liberty were traveling 99% of the speed of light hit earth compared to a medium sized asteroid , like Mathlide, were traveling about 250 km/s squared, the statue of liberty would probably do the most damage. This is obvious to a point but forces are not just like this. Forces are everywhere and everything interacts with everything, especially at distances very great. Right now, the most forceful object we have is the Earth, but we're also being pulled on by everything in the universe. They are significantly less than the forces we feel on Earth, but they are there and they are acting on the Earth, the Sun, the Galaxy. This however, does not mean that the rapid expansion of the universe is nullified. That is a different force that was here since the beginning of time and before it existed. However, if there were just empty space where there are no forces, and hypothetically two objects just appeared, they would slowly come together. This is gravitational force which is a property of all matter. The idea of matter having gravity is not new, but it is not the best explained. With particle accelerators, we can find how these forces interact and the best theory we have (scientific explanation, not guess) is called the higgs boson field, in which particles similar to a photon will create a field around an object that can attract other higgs fields. This is a simple explanation of it and it will not cover all of the specifics of the higgs. There are many of particles that do many forces, not all particles are created equally and not all quarks are also made the same and there are many different types of quarks that do certain functions to make atomic structures like neutrons, positrons, protons, and electrons.
