Physics is a natural science concerned with the study of matter and it’s relation to space and time. It looks at concepts related to this like energy and force in order to understand the behaviors of the universe.

Information Can Escape from a Black Hole


The Black Hole Information Paradox suggests information can’t escape a black hole intact. While new theories show information may be able to escape, it hasn’t been proven as of 2016.

We Might Be in a Virtual Simulation


The simulation argument can be summarized as the idea that reality might be a virtual simulation (we might be “in the Matrix” / “in a video game”).

Human Behavior can be Random


Human behavior can be random to some extent, but most behavior is based on prior input, and thus is “deterministic” (meaning not totally random).

If a Tree Falls in a Forest and No One Can Hear it, it Makes a Sound


If a tree falls in the forest, and there’s nobody around to hear, does it make a sound?

According to physics, if a tree falls and no one is around to hear it, it still makes a sound. Sound is a mechanical wave of pressure and displacement through a medium such as air or water. We don’t have to perceive a sound to know the laws of physics are in play.
