Information Can Escape from a Black Hole Myth
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.
Gravity
Gravity is the mass of objects curving spacetime which results in things with mass being pulled toward each other.

The Standard Model Shows How Elementary Particles Interact Fact
The standard model of particle physics shows how the elementary particles interact via the four forces to create the physical universe.
Gravitational Waves are Ripples in Spacetime Fact
Gravity is the result of the curvature of spacetime by matter. Non-symmetric acceleration of matter produces gravitational waves that ripple across the universe at light speed.
The Dark Side of the Moon Is Always Dark Myth
The “Dark Side” of the moon is not actually dark. Every month, it gets two weeks of sunlight and two weeks of darkness, just like the rest of the moon.
There are Four Fundamental Forces Fact
There are four fundamental forces (interactions) in the universe: gravitational, electromagnetic, strong nuclear, and weak nuclear.
There are Different Ways to Measure Mass Fact
There are different ways to measure mass, but all of them are related to rest-mass (invariant mass) the “true” inertial mass of an object at rest.
Time is Relative Fact
Time is relative to speed and gravity (time dilation), and so is space (length contraction). Light speed is constant for all observers, so time and space can’t be.
