The truly great thing about physics is that it is universal. Literally. What we discover about physics here in the United States is true in South Africa, and what is discovered in South Africa can be learned just as well in Vietnam, and it all holds true on Jupiter or in the Andromeda Galexy. Physics is based in mathematics and repeatable experiments and it can be understood anywhere. It takes our perceptions and it boils them down into their most simplistic forms, tests them, repeats the test, and then determines what is real and what is unsupported. This means that physics has the ability to help us understand things in incredible new ways. We can better understand the universe and how it is held together, but only if we can study the physics and step beyond ourselves to understand what the tests, experiments, and math are trying to explain to us.
For Amanda Gefter, this is one of the best parts of physics. It takes our expectations, our assumptions, and what we want to be true, and completely ignores it. A good scientist, during their search for what is real and what is not, is able to cut through the noise of our expectations, beliefs, and desires to see the science underneath, holding things together.
Gefter writes, “That was what I loved about physics—that moment of pure surprise when you suddenly realize that what you had thought was one thing is really something else, or that two things that seemed so different are really two ways of looking at the very same thing. It was the perennial comfort that comes from discovering that the world is not remotely what it seems.”
By cutting through the noise of humanity, physics helps us to see the world more thoroughly. The world and the universe are not the way they simply appears to us from our perspective on Earth. Much of how we interpret and understand the universe is through what we see, but so much of the universe does not emit electromagnetic radiation or react with light in any way. How we perceive the universe depends on our point of view, and of our experience as human beings living on our planet. What physics does, is move beyond our experience of the universe to tell us how things are at any point in the universe, not just on planet Earth today. If we accept the world as it appears to us, then we somehow cease to move forward, and we begin to live in a story that never completely captures the reality we experience around us. We begin to live in ways that don’t add up, that put us at the center and don’t allow for the types of evolution and adaptation that we need to live in this universe responsibly. Physics takes the stories that we tell and re-writes them, adjusting the language to be the language of mathematics, giving us a new perspective from which to tell our story.
