"One of the most remarkable facts about the Universe is simply that, over the past couple of centuries, humanity has actually been able to make sense of much of it at a basic, fundamental level. We've determined what all of the luminous and light-blocking material, plus radiation, is made of: the normal matter and energy in our Universe that consists of particles within the Standard Model."
"We've determined what all of the luminous and light-blocking material, plus radiation, is made of: the normal matter and energy in our Universe that consists of particles within the Standard Model. We've discovered black holes and have come to understand how gravity and the expanding Universe works: governed by the laws of Einstein's General Relativity. And we understand the rules governing how particles interact: through the strong nuclear, weak nuclear, and electromagnetic forces, as dictated by quantum field theory."
Humanity has identified the composition of luminous and obscuring material and radiation as normal matter and energy composed of particles within the Standard Model. Black holes have been discovered and gravity and cosmic expansion are governed by Einstein's General Relativity. Particle interactions are described by quantum field theory through strong, weak, and electromagnetic forces. Precise collider experiments, space-based detectors, and astrophysical and cosmological observations have cemented these frameworks over the last fifty years. The Standard Model of particle physics and the Standard Model of cosmology form the foundation of modern science. Research into extensions and alternatives seeks testable predictions from the full body of data.
