How does quantum physics help us understand space?
Before we dive into answering the end all be all question of how quantum physics helps us understand space, we need to understand what it is, who helped discover it and what are some differences between classical physics and quantum physics to be able to understand how it helps us understand space better.
What is Quantum physics/mechanics?
Quantum physics is a part of physics that explains things that aren’t normally explainable with classical physics on a smaller scale hence the “quantum” in the name. With many atoms on a smaller scale they react differently on said scale rather than if they were the size of everyday objects where we would be able to apply the equations of classical physics to. Due to physics being different the smaller things get things like dual particles which are particles that exist in 2 areas at the same time have an effect on the surrounding area. There is phenomenon which was created due to this which is known as “Quantum Superposition” which relates to the position speed and colour of some particles. Particles of light: “light can sometimes behave as a particle. Light behaves similarly to ripples on a lake in that it bounces off walls and bends around corners, and that the crests and troughs of the wave can add up or cancel out. Added wave crests result in brighter light, while waves that cancel out produce darkness.”
Who helped discover quantum mechanics?
Here I have a few people who helped discover or advance with their experiment or theory that they put forth to advance our everyday society both technologically and socially. The first one I’d like to mention is Erwin Schrodinger who is an austrian physicist who put forth his thought experiment now known as “Schrodinger’s Cat” which involved putting a cat in a box with a radioactive substance that had a 50% chance of killing it@0:07.
We can’t forget to mention one of the bigger physicists who helped revolutionize modern physics, Albert Einstein who developed his “theory of relativity” which is made up of both special relativity relating to interactions of particles excluding their interaction of gravity and General Relativity which relates to how gravity works and affects things around us.
The last person I’d like to mention which established a well known concept in quantum physics is Werner Heisenberg, he was known for his “Uncertainty Principle” which takes into account any mathematical inequality that has a foundational limit where some combinations of particles known as momentum and position are able to be known.
What are some differences between classical physics and quantum physics?
The differences between classical physics and quantum physics doesn’t solely depend on just mathematics alone, the way that atoms interact in quantum physics can be very different and yet similar to classical physics at the same time. One example of this is with classical physics of which it is implied that there is only one reality that exists while with quantum physics due to many atoms and waves being able to exist at multiple places and points in time theories of multiple realities are possible. This picture down below shows just a few examples of the differences between classical physics and quantum physics.
Now that we can slightly understand what quantum physics is, who helped discover it and some differences between classical physics and quantum physics we can now ask ourselves how does quantum physics help us understand space. So the way that quantum physics helps us understand space is that because of quantum superposition which has come to because of dual particles and different waves existing at multiple points at once. Because of this, many light particles, and radio waves that normally wouldn’t reach us are able to because of this phenomenon. This allows us to see a lot more of the universe than we would be able to if quantum physics didn’t exist. There isn’t a single conclusion or answer that can be taken of how it helps us understand space due to the amount of physicians contributing everyday and more and more theories coming out about space and quantum physics, which means that many theories could become invalid in the future.
