It doesn’t take much to realize that science is awesome! For example, you probably already know that everything is made up of atoms. Those atoms have a few protons and neutrons in the nucleus and then they are surrounded by electrons that orbit the nucleus like little moons (simplified explanation). At any rate, the most interesting thing about atoms is that they are about 99.99% empty space. That’s right. This screen consists of atoms. And those atoms consists of almost nothing. So why is it that you don’t see right through the screen. In fact, how is it that we can see/feel/stand on anything at all? It’s because of forces. Those atoms in the table (in spite of just being mostly empty space) actually repel the atoms (aka empty space) in your hand. So what you are touching isn’t actually a “thing”. When you touch something you are actually experiencing a repulsive force, kind of like gravity. And since those empty atoms reflect photons, you cannot see through them. You only see the photons being reflected off of what is essentially empty space. Crazy right?!
See we told you science was awesome! Just wait til you read about all the other scientific truths found in this list! So if you’re ready to give your brain a challenge, read on! These are 25 mind bending scientific truths to challenge your brain.
The conspiracy theory-laden social media onslaught unleashed by rapper B.o.B. got us thinking about another famous “the Earth is flat!” believer. Charles K. Johnson was the most notorious name associated with flat-Earth theories since Christopher Columbus. And he became something of a celebrity because of it.
Charles Kenneth Johnson was born in 1924. He became president of the International Flat Earth Society in 1972—but he’d believed the Earth was a flat planet since he was a child growing up in Texas and couldn’t wrap his head around the concept of gravity. He kept those beliefs with him during his 25 years working as an airplane mechanic in San Francisco. Eventually, he moved to the Mojave Desert and made a career shift into activism. He took over running the Society when its previous leader, Johnson’s good friend Samuel Shenton, passed away and designated him as successor. Shenton had founded the group in the 1950s but traced its origins back to 19th century England.
That Johnson’s desert abode was so close to Edwards Air Force Base, home of NASA’s Armstrong Flight Research Center, only made it more curious how strongly Johnson stuck to his beliefs. He believed the space program was a full-on hoax. In 1980, he gave an interview to Science Digest in which he opined “You can’t orbit a flat earth. The Space Shuttle is a joke—and a very ludicrous joke.”
Quantum mechanics is a beautiful and still-controversial idea. It is rightly popular. What’s not right is the way people use it to justify any reality-bending idea in their novels, their TV shows, or their personal philosophies. “Quantum” does not mean anything you want.
“Captain? I’m afraid we’re getting quantum disruptions in the quantum energy field. Should I ready the quantum torpedoes and relay a quantum message to the quantum base?”
I’m not a savvy dissector of movies. All the physics mistakes in Gravity flew right past me, but when you see something done a certain amount of times, it works even the most unresponsive of nerves. The word “quantum” is regularly dropped into science fiction in a way that basically amounts to the storyteller thinking, “I bet this is the way smart people in the future talk.” It might be the way smart people talk, but as we see in the next section, it’s also the way people talk when they’re being really stupid. What’s more, it won’t be the way the educated people of the future talk about anything.
Science can move forward in sweeping generalities, or it can move forward by becoming more and more specific. Either way, you probably shouldn’t use “quantum” to describe future science. If you’ve got a universe where starships can move at above light speed, or people can teleport, or the brain can be uploaded into a computer, the term “quantum” may be as antiquated as the term “natural philosophy.”
If the term “quantum” is still around, it won’t be applicable in any specific situation. Let’s put it this way, there are five different major types of light scattering – Rayleigh Scattering, Mie Scattering, Tyndall Scattering, Brillouin Scattering, and Raman Scattering. If you’re an expert and working with scattered light in any meaningful way, saying, “light is being scattered,” isn’t specific enough to get anything done. You have to know what kind of scattering you’re dealing with. Having characters in a space craft worry about a “quantum energy field” near them makes about as much sense as having characters in a war say that the enemy is shooting “matter” at them. They’ll need to use specifics to make any progress.
A fun note: the types of light scattering are all named after scientists. Instead of saying “a quantum energy field,” have your characters run into “a Bass-Van-der-Woodsen field,” because in your universe the team of Bass and Van der Woodsen made the discovery, and an educated expert would name the field instead of just saying “it’s quantum.”
It Doesn’t Mean That We Are Psychic
Okay, here’s the big one. Quantum mechanics shows that the world works in unintuitive ways, and, yes, experiments done in quantum mechanics provide results that can be interpreted in ways that lead us to odd conclusions. What quantum mechanics doesn’t do is provide evidence for whatever whack-a-doodle theory any crackpot has at the moment. These theories come in several different flavors.
First there’s quantum entanglement. I have to admit, I have a soft spot for quantum entanglement. Entanglement involves two particles having opposite spins. As long as the spins aren’t measured, they’re undetermined. This doesn’t mean that we don’t know the spins. This means that they are literally . . .

I bet you think you know what science is for.
I bet you subscribe to such ideas as “science is a means for understanding the universe” or “science provides a method for the betterment of humankind.” And I bet that you think that, by and large, scientists are working to elucidate the actual mechanisms by which nature works, and telling us the truth about what they find.
Ha. A lot you know.
Yesterday I found out that scientists are actually all in cahoots to pull the wool over our eyes, and are actively lying to us about what they find out. They work to stamp out the findings of any dissenters (and, if that doesn’t work, the dissenters themselves), and to buoy up a worldview that is factually incorrect.
Why would they do this, you may ask?
I… um. Let’s see. That’s a good question.
Well, because they’re that evil, that’s why. And you know, that’s how conspiracies work. They just cover stuff up, sometimes for the sheer fun of doing it. Even the scientists gotta get their jollies somehow, right? I mean, at the end of the day, rubbing your hands together and cackling maniacally only gets you so far.
I came to this rather alarming realization due to a website I ran into called, “Is Gravity a Pulling or a Pushing Force?” wherein we find out that what we learned in high school physics, to wit, that gravity is attractive, is actually backwards. Gravity isn’t pulling us toward the center of mass of the Earth, like your physics teacher told you. It’s more that… space is pushing you down.
It’s a little like my wife’s theory that light bulbs don’t illuminate a room by emitting light, they do it by sucking up dark. She has been known to say, “Gordon, when you get a chance, can you replace the Dark Sucker in the downstairs bathroom?” Presumably when the filaments in the bulb become saturated with dark, they become incapable of doing their job any more and need to be replaced.
But unlike my wife, the people on this website are serious. Here is one representative section from the website . . .
