" ... Every form of energy in the Universe, no matter how weird, exotic, or unfamiliar it is, obeys the same law of gravity: Einstein's General Relativity. Most of the types of energy we're used to come in the form of quanta: tiny little point-like packets of energy that move through the fabric of spacetime. Some of those quanta are radiation-like, meaning they move at the speed of light (or indistinguishably close to the speed of light). Others are matter-like, meaning they're moving slow compared to the speed of light. ... "
" ... It’s often been said that, “science doesn’t care what you believe,” but the truth is that science doesn’t care what everyone believes. The Universe, as best as we can measure it, obeys certain rules and yields certain outcomes when we test it under controlled experimental conditions. The reason scientists so often find themselves surprised is that you cannot know the outcome of a new experiment until you perform it. The results of these experiments and the knowledge that comes along with it is available to anyone who reproduces the experiment. The results are found in nature, and anyone’s opinion on a scientific matter that’s been decided by the evidence is moot. ... "
" ... Nature simply obeys principles of physics, chemistry, and biology that we do not yet fully understand. ... "
" ... The Universe, and every physical thing within it, obeys the same fundamental, underlying rules. Discovering and understanding those rules, and how they apply to any particular phenomenon, is the most successful tool — arguably, the only reliably successful tool — humanity has ever developed to tackle the problems that face us. As 2020 comes to an end and we face the dawn of 2021, this is the one fact we should all not only embrace, but demand that we weave into the very fabric of our civilization. ... "
" ... The problem is that the photon's reference frame isn't an inertial reference frame: In an inertial reference frame, there are physical laws which don't depend on the motion of anything external to the system. Yet for a photon, the physical rules it obeys depend exclusively on everything going on external to it. You cannot calculate anything meaningful for it from the photon's reference frame alone. ... "
