Amazing Scientific Discoveries (21 pics)

1

"About 99.86% of all the mass in the solar system is inside the sun. The Earth has about 0.0003% of the solar system's mass. We are decimal dust."

2

"Mushrooms are closer to animals than to plants. In fact, in our current phylogenetic classification, fungi are even closer to animals than to slime moulds."

3

"The earth is only about 20 galactic years old. Meaning it has only completed 20 full orbits around the galaxy."

4

"Your stomach lining regenerates every few days. Otherwise stomach acid would literally digest your own organs. You're constantly saving yourself from yourself."

5

"If you were to stretch out all of the DNA in a single cell, it would measure 2 meters or 6.5 ft! On a more macro scale, the surface area of human lungs is equivalent to a tennis court."

6

"Your brain can’t feel pain. Surgeons can operate on it while a patient is awake."

7

"For 186 million years, giant reptiles absolutely dominated the planet, on land, in the sky, and in the rivers and oceans, until a single asteroid ended it all.
Extinction events are usually more complex or drawn out over thousands or millions of years, but the one that happened 66 million years ago was caused by a single extremely rare event that happened on one random day. "

8

"Coal exists because the fungi and bacteria that digest trees did not evolve until much later."

9

"The atoms in your body are older than the Earth. Most of them were formed inside exploding stars billions of years ago. You’re literally recycled stardust walking around arguing about WiFi speed."

10

"Sharks are older than trees, and jellyfish are older than sharks. "

11

"Your entire life is almost two times less than one Neptunian year. If you’ve lived for a hundred years and died, Neptune would still have to travel 65 more years after your death, to complete a single orbit. "

12

"Your eyes can send way more data than your optic nerve can carry. We don't know how your eyes decide what data to send and what data to ignore."

13

"Spiders eat more biomass weight each year than the combined weight of all of the humans on earth, up to 800 million metric tons."

14

"Your brain made up the entire experience of “reality.”
You’ve never actually seen color, felt texture, or heard sound the way they truly exist. Your brain just translates electrical signals into a fully immersive simulation and goes, “yeah this seems real.”

15

"You only become aware of your decisions after you've already made them. The feeling of "making decisions" is an illusion your brain generates for you after the fact."

16

"If the sun vanished tomorrow, all life on the surface would die within a few weeks, but life in the deeper parts of oceans would survive. The residual heat in the Earth's core would be enough to sustain life there for several billion years."

17

"If you removed all the empty space from the atoms that make up every human on Earth, the entire population would fit inside the volume of an apple. We are basically 99.99% nothingness held together by energy."

18

"Black holes warp both space and time the closer you get to it. When you cross the event horizon, space and time become so warped they actually switch places."

19

"Birds are dinosaurs. Not closely related to dinosaurs, not evolved from dinosaurs, but actual real living dinosaurs."

20

"We know more about our solar system than we do about the contents of our own oceans."
