You simply can't walk through walls. Because according to the Pauli Exclusion Principle, no two particles can exist in the same place - it's just impossible for both the particles -- within the limits set by the uncertainty principle -- to have the same position and same velocity.
String Theory explains that fundamental particles, such as quarks, electrons, and neutrinos are all composed of smaller, vibrating, strings of energy, and a different modes of vibration of these strings result in different particles we perceive in nature. But is this theory really true?
A day is the amount of time it takes for a planet to spin around and make one full rotation with respect to the Sun. On Earth, it's about 24 hours. But how long is a day on the Sun?
Researchers say you can predict what number a rolled die would most likely land on - if you precisely understand the viscosity of air, the friction of the table and the acceleration due to gravity. So, does this mean we can predict anything - or is anything truly random?
A hydrogen atom has less mass than the combined mass of the proton and electron that make it up. Weird, right? So how can something weigh less than the sum of its parts? Well, it all comes down to famous equation in physics, that is Einstein's E = mc². In this episode of PBS Space Time, Gabe Perez-Giz explains what this famous equation really says.
The answer is 42. Yes, I am serious.
You’ve probably heard about black hole as a space-time region that exhibits such strong gravitational pull that no particle and radiation can escape from inside it. So, if nothing can […]
According to Einstein’s famous equation E=mc^2, anything with mass has a huge amount of energy. Well, there are basically three ways to generate energy: chemical reactions, nuclear reactions, and gravitational […]
