This thread was made for anybody to post science facts in. They can be interesting, scary, funny, about the human body, about scientists themselves or anything else. It doesn't matter how many you have. Share them here and learn from what others post. Let's see who has the best.

-The Voyager 2 spacecraft is traveling at 38,000 mph. From where it's currently at and continuing at that speed, it could reach the center of the Milky Way in 450,000,000 years.

-In the female body, there are bacteria residing inside the uterus that prevent yeast infections.

- There are 3 types of supernovae- Type I, Type IIA and Type IIB.

There is nothing faster than the speed of light, which is 3e8 m/s and it acts as both a particle and a wave. Some experiments are display it having particle properties, while other experiments show wave properties, and some show both of them together. This gives the conclusion that light is both a particle and a wave.

Cyro Xero : Do we need to have a backings or evidence or citations in any way, just so we won't be posting anything that is not deemed as fact at this point?

play4fun : It's a good idea, but only if you want to. Sometimes members may have facts that are true but can't or can no longer find sources to back them. But putting a source in may encourage someone to check and learn more info from it.

The blue whale can produce sounds up to 188 decibels. This is the loudest sound produced by a living animal and has been detected as far away as 530 miles.

There are no poisonous snakes in Maine.

legacyme3 : You lucky son of a......

vizwiz123 :

I know I am. =3

I love not having to deal with poisonous snakes =3

There are 60,000 miles of blood vessels in the human body.
An individual blood cell takes about 60 seconds to make a complete circuit of the body.

Wow, some interesting stuff in here so far. I like it.


- Hydrogen peroxide bubbles on wounds not because it is killing germs, but because it decomposes into water and oxygen gas in the presence of enzymes from broken skin cells.

- The term "Hypervelocity" usually refers to a very high velocity, typically over 6,700 mph or Mach 8.8. In particular, it refers to velocities that are high enough that the strength of the materials being impacted are very small compared to inertial stresses. In a hypervelocity impact, the impactor, as well as the surface it hits, can undergo temporary liquefaction, even metals can behave like fluids in these circumstances. Extreme hypervelocity results in vaporization of the impactor and target. Meteorite craters are an example of hypervelocity impact.

- Vanilla flowers may only be naturally pollinated by a specific bee found in Mexico. Vanilla grown elsewhere must have each flower individually pollinated by human workers.

- A meteoroid is particle floating in outer space that has a size ranging between a grain of sand and large boulder 10-50 meters across. Once a meteoroid enters the earth's atmosphere and becomes visible, it is considered a meteor. Most meteors burn up before they reach the ground. The remains of a meteor that impacts the earth, if it is not vaporized by the impact, is called a meteorite. Anything larger than a meteoroid is considered an asteroid.

Energy can neither be Created nor destroyed it simply changes form.

I.E. The energy used to power your cellphone comes from a natural source of energy like Water,Wind,or even solar energy is collected and stored in a grid that we can tap into and benifit from.

Well, I have these.

-Birds fly in V-formation in order to save energy.
-If we could ever find a body of water large enough, Saturn would float in it.
-Mark Twain predicted he'd die on Halley's Comet's next arrival, and he did.

Okay, I have 2.

- The average human brain weighs 350 grams.
- Fleas can jump 130 times higher than their own height. In human terms this is equal to a 6ft. person jumping 780 ft. into the air.

What about these

- there are 206 bones in the adult human body and there are 300 in children (as they grow some of the bones fuse together).
- the most dangerous animal in the world is the common housefly. Because of their habits of visiting animal waste, they transmit more diseases than any other animal
– if you could drive your car straight up you would arrive in space in just over an hour
– human tapeworms can grow up to 22.9m

Honey is the only food that does not spoil. Honey found in the tombs of Egyptian pharaohs has been tasted by archaeologists and found edible.

The average human spends about 30 minutes of their life as a single cell, also McDonalds fries do not spoil.

The effect of Relativity made Astronaut Sergei Avdeyev a fraction of a second younger upon his return to Earth after 747 days in space.

Human jaw muscles can generate a force of 200 pounds (90.8 kilograms) on the molars.

I read somewhere that humans have been known, during sleep, to clench their teeth with a force of 600 lbs. I don't know how their teeth stay intact, but that's quite a massive amount of pressure.

What's the difference between spiders and insects?

Despite the visual similarities between the two both are actually members of distinct families. Spiders are members of the Arachnid family whilst insects belong to the Insect family. So what makes the two families different ?

Well for starters spiders have 8 legs whilst insects have just 6. Insects have 3 distinct body parts, a head, thorax and abdomen whilst spiders have just 2, a combined head and thorax known as the cephalothorax and an abdomen.

I'd also like to add to those fact by saying spiders also have hairs on them which, believe it or not, classifies them as mammals

the study of plants is called botany (most don't know)

Did you know....Mosquitos are attracted most to the color blue?

I won't be wearing blue during the summer, that's for sure!
