People Share The Best Random Science Facts They Know


Can this get me on Jeopardy?!

Science is not for everybody. I for one dropped out of chemistry the first day in high school. That was just too much compound drama for me. It doesn't mean that I don't find science fascinating, I do. It is an endless well of knowledge that leads to the answers of life. How we and the Earth and nature all connect is exciting. I just wish it could be explained in terms that every laymen could understand and appreciate. Because science is sexy.....

Redditor u/Look_Under_The_Bed wanted to hear what little know facts that can lead to genius level knowledge by asking.... What's a random science fact that you know?

Clear the Pipes

When you cry really hard, your nose runs because it's connected to the same pipes as your tear ducts, so your nose is also helping you get your tears out.


The Gait

Severe diabetic neuropathy in the feet causes a walking gait similar to people with leprosy. Normally you change your gait throughout the day from longer to shorter strides, and alter your foot position as they get achey or tired.

Since diabetic neuropathy damages both sensation and position sense, diabetics do not change their gait to alleviate pain, can develop a "slapping" gait (so they can feel the ground) and are susceptible to falls. They develop Charcot joint as a result of repeated injury (destruction of ankle joint), can have "rocker bottom" feet, toe deformities, and of course, diabetic foot ulcers.

Interestingly both diabetics and lepers can develop an indifferent attitude toward the significant foot injuries, even when amputation is threatened. "It doesn't hurt, what's the big deal?"

A lot of research regarding diabetic neuropathy was done in Louisiana using armadillos which can carry leprosy. BTW leprosy also attacks nerves, usually in the coolest body areas: nose, elbows, hands, feet.

Fun fact: people with leprosy lose their eyebrows.

Edit: I should add that leprosy doesn't cause your body to rot away. The mechanism of injury is similar in lepers and diabetics- anesthesia causes unintended injury such as picking up something too hot, too hard ; stepping on sharp objects, gait trauma, etc. The injuries and their sequela cause infection, repeated trauma, and the resultant deformity you see.


GPS Origins... 

Time is slightly slower between higher altitudes and lower altitudes, to infinitesimal fractions of a second.


The designers of the GPS satellites had to compensate for this, since the entire system is built around ridiculously precise timekeeping. It was calculated theoretically first as a consequence of general relativity, and then confirmed experimentally.

Squirrels can survive falling from terminal velocity.


I learned this after witnessing a squirrel hit the ground after a presumably long fall. It made a loud SMACK as it hit the ground, scared the crap out of me and the dog, then scampered away, up another tree like nothing happened.



Muscles can only contract. Muscle tissue can't push. Doesn't sound like a big deal until you realize that actions like sticking your tongue out of your mouth are completely the result of pulling, not pushing.


You Spin Me Round....

Venus the only planet to spin clockwise.


Sun's axis rotates a full turn about every 27 Earth days but since the Sun is not solid but a ball of plasma the rotation speeds are different at different latitudes. At the equator it's surface rotates faster, every 24 days.

Another fun fact: the orbital plane of the planets is tilted about 7 degrees in relation to the Sun's axis mentioned above. This should not be the case because of the way planets form around a star. Astronomer's suspect that the orbital plane of the planets tilted as a result of the gravity of a large planet size object that is no longer around. Existence of this planet is hypothetical so it was given a name Planet X (or sometimes Planet 9). Other anomalies had been observed that could also suggest existence of such an object.

Example: grouping of planetoids on the outskirts of the Solar System. The reason that the planet hasn't been observed directly is that it's so far away beyond Neptune that it doesn't reflect enough sunlight to be seen with available technology. Another proposed explanation for the orbital plane tilt is existence of a nearby planet-sized black hole which orbits the Sun but hasn't been detected yet. The new James Webb space telescope that will be launched soon should help to answer those questions.



You're closer to space than you are to anything more than about an hour's drive away.

Most folks take "space" to be "outside of Earth's atmosphere."

There's no precise boundary to where Earth's atmosphere ends and space starts, but a lot of people take the Kármán line to be as good a point as any to split atmosphere vs. space. This line is 100km / 62 miles up, which is roughly the distance your grandma can drive in an hour on the highway.


Seeing Red....

If you bleed more than 100ml/min on the international space station, they write you off and say any medical supplies spent on you is a waste.


Burn baby Burn....

Chlorine trifluoride burns literally everything

It is, of course, extremely toxic, but that's the least of the problem. It is hypergolic with every known fuel, and so rapidly hypergolic that no ignition delay has ever been measured.
It is also hypergolic with such things as cloth, wood, and test engineers, not to mention asbestos, sand, and water—with which it reacts explosively.
It can be kept in some of the ordinary structural metals—steel, copper, aluminum, etc.—because of the formation of a thin film of insoluble metal fluoride that protects the bulk of the metal, just as the invisible coat of oxide on aluminum keeps it from burning up in the atmosphere.
If, however, this coat is melted or scrubbed off, and has no chance to reform, the operator is confronted with the problem of coping with a metal-fluorine fire. For dealing with this situation, I have always recommended a good pair of running shoes.

John Drury Clark, Ignition!. Emphasis my own

It burns asbestos, the carcinogen used so damn much because it was so fire retardant

Oh Ladies....

Female bedbugs don't have vaginal openings on their bodies, instead the male bedbug has a sharp penis that stabs her and ejaculates into her bloodstream and the sperm cells float around until they get to their destination.
