Our Solar System is a “Vortex” Myth
There is a video that shows our solar system as a vortex and says the heliocentric model of the solar system we know is wrong. However, the video is wrong and the heliocentric model is correct.
The Universe
The Universe is all time, space, energy, and matter. Essentially, anything within the closed system centering around the big bang.

Extraterrestrial Diamonds are Common Fact
Extraterrestrial diamonds are very common in the universe. It rains diamonds on some planets, other planets are made of diamonds, and there are even diamonds in stars!
Potentially, Everything is Light Fact
Nikola Tesla was said to have said “everything is light.” That is potentially correct. In theory, the universe could be explained by electromagnetic energy.
All Elementary Particles Exhibit Wave-Particle Duality Fact
All elementary particles exhibit wave-particle duality, acting as both a particle and a wave.
Visible Light is Electromagnetic Radiation Fact
Visible light is a range of wavelengths in the electromagnetic spectrum visible to the human eye (wavelengths of about 390 to 700 nm).
At Its Core, Chemistry is Physics Fact
On a fundamental level, chemistry can be explained by physics. The atoms that make up the periodic table elements are themselves made of quantum particles.
Sir Isaac Newton Discovered the Laws of Motion Fact
Sir Isaac Newton can be said to have discovered the laws of motion, but more accurately, he refined the work of Aristotle, Galileo, Descartes, and others.
Mercury is the Hottest Planet Myth
Mercury is the closest planet to the sun, and thus receives the most direct heat. However, Venus is hotter, as Mercury doesn’t have an atmosphere thick enough to trap and hold heat.
We Know How Many Galaxies There Are Myth
We don’t know exactly how many galaxies there are in the visible universe, but low estimates based on Hubble data start at 100 billion.
Light is Both a Particle and a Wave Fact
Light is a particle (a photon), that acts like a wave (“both a particle and a wave”), which can be measured as an excited quantized state of the electromagnetic field.
A Planck Unit Represents the Smallest Measurable Unit Fact
Planck units, based on the reduced Planck constant (ℏ) and Planck constant (h), represent the smallest measurable units in the physical universe.
All Particles are Made from Massless Particles Fact
All known particles are either massless energy particles, or are composite particles with mass that are made from massless energy particles.
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.
All Types of Systems are Generally Comparable Fact
General systems theory shows us there are commonalities between different types of physical and conceptual systems which we can study to better understand complex systems.
Everything Depends on Frame of Reference Fact
Everything we perceive depends on our frame of reference. What we observe is relative to our point of view. In other words, “it is all a matter of perspective”.
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.
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 Types of Infinity Fact
There are different types of infinity (∞) which differ by size, countability, “flavor” and more. Most types have practical real world applications.
Physics is Different than Metaphysics Fact
Physics is a branch of physical science rooted in math that asks “how does it work?” Metaphysics is a broad branch of philosophy that asks, “What is its true nature?”
Nothing Can Travel Faster Than the Speed of Light Fact
No “thing” (including particles) can travel faster than light speed, but some “non-things” can. In both ways “nothing travels faster than the speed of light”.
The Earth Isn’t Flat Fact
The Earth is not flat; the Earth is an oblate spheroid (a bumpy sphere with a fat equator and skinny poles). There are many ways to prove the earth’s geometry.
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.
E=mc^2 (Mass and Energy are Equivalent) Fact
Einstein’s mass-energy equivalence equation (E=mc2) shows that mass and energy are equivalent (but not “exactly the same”) properties of a physical system.
There are More than 8 Planets in Our Solar System Myth
There are 8 known planets in our solar system, indirect evidence of a 9th as of 2016, 5 major dwarf planets including Pluto, and many smaller dwarf planets.
Everything is Made of “Star Stuff” Fact
As Carl Sagan correctly stated, “we are made from star stuff”. The elements in our body, and everywhere else were transformed by nucleosynthesis in stars.
There are Elements We Don’t Know About Myth
There are elements we haven’t observed occurring (naturally or in a lab), but we can predict the location and properties of “undiscovered” elements.
Diamond is the Hardest Natural Substance Myth
Diamond is the most common of the naturally occurring “hardest” substances, but Q-carbon, wurtzite BN, lonsdaleite, ultrahard fullerene, graphene, and carbyne are all harder.
Water Bears are the Only Known Animals to Survive in Space Fact
Water bears (tardigrades) are the only known animals to survive the vacuum of space. Water bears are extremophiles, meaning that they can survive extreme conditions (like high temperatures, and high pressure).
The Universe is Mostly Empty Space Myth
The universe and everything in it, including humans, is mostly “empty space.” However, space is not actually “empty,” it’s filled with quantum fields and dark energy.
