Ah, science. The framework for literally everything in existence. Learning science as a kid in school could get super boring, but every now and then there's those facts you learn that make you look at the subject in a whole new way. Here are some of those facts.

One Redditor asked:

What's the most mindblowing and mesmerizing science fact not much people know about


"You can build a device at home for about $30 to see subatomic particles. It's called a cloud chamber, and muons from cosmic rays, or alpha particles from americium taken from a smoke detector will leave trails of condensation that you can see with your own eyes."


"Here is a video of a piece of uranium in a cloud chamber. The slower, larger particles (mainly alpha particles aka helium nuclei) leave the shorter fatter trails."

"And here is a guide to building a cloud chamber at home. How much you see depends on things like whether or not you are indoors, and your altitude. In order to increase the amount of radiation you see, you can take the americium out of a smoke detector. Americium is radioactive (you are totally safe unless you do something stupid like swallow it, and even then choking is probably* your bigger concern), and will randomly release alpha particles that your cloud chamber will pick up."


I'd drink that.


"Near the centre of the Milky Way, there's a dust cloud known as Sagittarius B2. This dust cloud is really, really big -- almost 150 light years across -- and has a mass about 3 million times that of the sun. Spectrographic analysis has shown what it's made of, and it has fairly high concentrations of both ethanol (which is what gives you the buzz when you make a cocktail), and ethyl formate -- a compound which has a distinct smell of rum, and is also one of the compounds that gives raspberries their taste."

"If you could condense it down to a level where it was detectable, then, the centre of the galaxy would smell not dissimilar to a raspberry daiquiri."


Mind. Blown.

"You have probably heard that there are more stars in the universe than grains of sand on Earth."

"But what I find more amazing is that there are more atoms in a single grain of sand than grains of sand on Earth. Just shows you how small they really are."


Say its name three times.

"If Betelgeuse, a fairly nearby giant star, goes supernova, it will light up our sky for 2 months."


"The really freaky thing is that if it went supernova today, because of its distance, the light wouldn't reach the earth for over 600 years."


She thicc.


"The mass of the Sun makes up 99.98 percent of the total mass of our solar system."


"And Jupiter takes up most of the remaining mass."


Just some confused particles.

"If you take two different types of metal and hold them together in Space they will bond together in a process called "cold-welding".


"I loved how a friend of mine explained it:"

"Then the two metals touch and there is nothing in between. So the electrons start going out for a walk and they become confused because they don't know where one piece of metal ends and where the other one begins. So they wander around both and BOOM now it is just one piece of metal because the electrons don't know where they are."


Mud world!

"Sharks existed before trees!!!"


"And grass. Right? Grass wasn't around either. All those dino movies with lush grassy floors. IT WASN'T THERE! MUD WORLD!"




"Humans are bioluminescent and glow in the dark, but the light that we emit is 1,000 times weaker than our human eyes are able to pick up."


"Poor humans, their glow is so lovely and they can't even see it."


The past is in the past.

"The images your eyes give are 1/100th of a second in the past."

"Because of the time it takes your brain to process inputs from all senses, what is happening in front of you is 1/100th of a second behind."


"Yeah. It's crazy how the present doesn't actually exist."



"Water can boil and freeze at the same time:"

"It's called the triple point, and it occurs when the temperature and pressure is just right for the three phases (gas, liquid, and solid) of a substance to coexist in thermodynamic equilibrium."


This sounds fake.


"If you move backwards at the speed of light, you will see a still of the very thing you saw before you started moving, until you slow down."



"The Amazon rainforest, which is quickly being destroyed, produces 20% of all oxygen on Earth. If the amazon rainforest is cut down, breathing difficulties will become much more common and much more threatening. Just shows how much we are killing ourselves by killing our planet."


We'd all be so tiny!

"Supermassive black holes have masses millions to billions times greater than the sun and have such a great gravitational pull that IF it would swallow the earth we would be compressed to the roughly size of a marble."


Pretty colors.


"Mantis shrimps can see in 12-15 different colours, while humans can only see in 3."

"Bonus colour fact: you have no way of knowing that the colour you know as red is the same as the colour everyone else knows as red."

"Bonus mantis shrimp fact: when they "punch", their fists move at around 50mph; bubbles caught near the punch have hit temperatures exceeding 4000 Celsius, nearly the surface temperature of the sun."



"If you compact a human's atoms, it would all fit inside the head of a pin."


There is so much out there to learn! Do you have similar things to share? Let us know.

Some people are far more conscious of their health than others.

Be it out of obligation or self-interest, many people make a point of avoiding certain foods and products, and partaking in extreme diets and exercise plans.

Which doesn't mean they avoid unhealthy habits or products altogether.

Indeed, all of us are probably unaware that we all likely partake in eating food, using products, or even performing what might seem like everyday activities which could be harmful to our health.

Be it by happenstance or obligation.

I'm always stunned by bad parenting.

And I see it far too often.

People need a license to drive.

A license to fish.

But having kids?

Let anybody do it. Sure.

So many kids deserve better.

Mirror, mirror on the wall, who is the smartest of them all?

Who is today's best and brightest?

Are they in charge of Mensa?

There are a lot of brilliant people in the world.

But if we can compare; who measures up to the greats?

Two words: Albert Einstein.

The new generation.

CW: Suicide.

Finding a dead body is one of my worst fears.

The only one I've ever found was my grandma's.

She was dying of cancer so it wasn't horrific.

Blood makes me faint, so any horrific scenes will not go well for me.
