Swagepi : Woah , that's a lot

Anyways, there is some stuff in eyes named after Pikachu , called......pikachurin(not-so-creative, but does that matter?)

And there is a protein named after Sonic the Hedgehog, called......Sonic Hedgehog (seriously)

Finally, there is a huge reservoir of water - as big as 140 trillion earth oceans- in outer space. It is supposedly floating around a black hole.

Here are a couple of Science facts that I found to be pretty interesting.

1. The word "Scientist" first appeared in 1833.

2. A 10 year old accidentally created a new molecule in science class. 

3. 41 new species are discovered by scientists every day.

And the most disturbing one...

4. Scientists have developed a way to charge mobile phones using urine....

Here's a neat one or two for you!

1. 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 as 530 miles away!

2. It's been estimated that, if we could make a map of all the synaptic connections within just a cubic millimeter of human brain tissue, it  could fill a petabyte of storage. If you don't know how big a petabyte is, it's enough to hold roughly 13.3 years of HDTV content. 

How our body produces energy can be boiled down to three words: movement of electrons.

It is possible that the CERN collider will create mini-black holes (if they haven't already).
These will evaporate within very tiny fractions of a second.

Our body has the processes to turn nearly any amino acid into another.

EideticMemory : Wait... black holes in our bodies? Am I reading that right? Is that what you are saying? 

thing1 :

Nope. I'm talking about:

http://en.wikipedia.org/wiki/Large_Hadron_Collider.

It might be able to create small black holes that last 10^-27 seconds or so.

The last part of:

http://home.web.cern.ch/about/physics/extra-dimensions-gravitons-and-tiny-black-holes

is a good read about it. The section on extra dimensions is pretty cool as well.

Here's a couple of crazy random science facts that I have just recently come across...

- There is a giant cave of natural gas somewhere in the country of Turkmenistan known as the "Door to Hell." Almost 45 years ago, scientists lit the cave on fire to see how long it would burn...it still burns today. I guess that would say something about natural gas and how long it could burn...
- Scientists used skin cells from mice to create stem cells. Those stem cells were used to create mice eggs that produced healthy baby mice. Those mice would later be able to reproduce mice on their own.
- If you were to remove all of the empty space from the atoms that make up every human on earth, the entire world's population could fit into an apple. 

MattyIce : Wow nice facts. But... I heard that human population would fit in a sugar cube instead. But well that still shows how much ridiculous amount of empty space things actually have.

If you thought that nature won't squeeze stuff like that, hehehe! There is actually an event like this that occurs, but at a huge scale- a "dying" HUGE star. If it is massive enough(as much mass as 10 SUNS or more) certain events occur which cause the star to collapse on itself(like shrinking itself, but getting denser) and you get a huge explosion, which is a type of SUPERNOVA! But it is after THAT we want to see what I really want to talk about.. well what is left over is a spherical object of about 7 miles radius... But guess what? It is as massive as 2 SUNS ! haha!

While the apple of humanity is hypothetical, we have about 2 Suns fit into size of a city out there in the Universe... actually we are supposed to have 3000 of them in our galaxy!

For those who want to know what this 2-sun-in-one-city stuff is called, it is named.... the ... Neutron Star... Guess what it contains!

faisal.97 : The material you are referring to would be neutrons. Electrically neutral particles slightly more massive than protons., which are crushed together with negatively charged particles in the process of the creation of said stellar object. Any more mass and the forces preventing the neutrons themselves from collapsing cannot prevent the formation of an event horizon and (possibly) a singularity.

Ferdinand : You are right Yeah it mostly contains neutrons. Well the formation actually happens in stages but I will skip to an exotic part: Electrons and protons fuse to form neutrons( plus ) due to immensely high temperatures reached as the dying star performs limit breaks(double references if anyone knows what I mean hehe). However, only one limit break is left and must not be performed by the star unless it wants to become the Black Hole(the singularity you mentioned). After that, well you have a city-size star which is packed with atoms at surface, free electrons and free neutrons in deeper sections, and then mystery matter in the middle(multiple stuff have been proposed)

So today's random fact: A neutron cannot remain itself for a long time on its own. After a random time, it will just decay into well... proton and electron(plus ). Sounds familiar? No, not the beta decay, but the exotic part of neutron star formation So... wouldn't neutrons in neutron stars just decay into protons and electrons? After all they are not bound to atoms or nuclei- they are just a huge army of free neutrons. Well, the answer is... yeah, there is just too much pressure on them to do such a thing(having 1 to 2 suns packed into a city is enough to provide that much pressure). So united they stand, divided they divide. interesting.

People will tell you you'll ruin your eyes from watching too much TV, or from staying too close to the screen. In actuality, there was only ever one television which would emit rays harmful enough to damage your eyes (released around the beginning of the television's life), but it was taken off the market for obvious reasons. We no longer have that problem. Enjoy your nice bright screen, kids.

faisal.97 : I did know about the weak force and it's effect on free neutrons but I'll admit I never even considered what that might mean for a stellar-mass object. Without google, I want to say they have a half-life of @ 15 mins.  I am also quite aware that although theorized, a proton has never been observed to decay. But anyways, what kind of mystery matter has been proposed? Some kind of quark mixture? When you start getting into QCD I start to get a bit lost. I've never given a whole lot of consideration to neutron stars actually since they never seemed as exotic as a black hole. A do know you won't be finding any spacecraft with a neutronium hull ala Star Trek though. I almost hate that show anymore for all the damage it's done for what people think is actually possible. Not really though, I'm a life-long Trekker. No cosplay though.

Ferdinand : Oh yeah you should use google and all Ok, mystery matter? Well this is from wikipedia:

"The composition of the superdense matter in the core remains uncertain. One model describes the core as superfluid neutron-degenerate matter (mostly neutrons, with some protons and electrons). More exotic forms of matter are possible, including degenerate strange matter (containing strange quarks in addition to up and down quarks), matter containing high-energy pions and kaons in addition to neutrons,[4] or ultra-dense quark-degenerate matter"

Oops why did I write proposed? that was a big mistake from my side. Rather these are possibilities from models.

Ok since you did not using google, the following part of the post is from my recall, and I won't verify my recall with websites like wikipedia

This post's random science "fact"(might be wrong) is superfluid. I think superfluid is like stuff that if you put in a glass, it flows up through the inner walls of the glass to the rim. I think some isotope of helium is like that(maybe helium-4 but yeah it sure requires tons of cooling to near absolute zero temperature if I remember well)

To tell you the truth, I haven't watched any Star Trek cuz I am not able to do so legally... but nice to know that they have spaceship with hull of neutronium(forgot what wikipedia "told" me about it, but i will let it have its own post here. Maybe just nucleus equivalent of neutron, which seems useless to me as I think I can use electrocute the spaceship to death. Cuz neutrons don't interact electromagnetically. Though I could be very wrong). But, doesn't Star Trek actually help people by showing the wrong stuff? Like since Star Trek is science.. fiction, then it means that real science is something else. But you must have lots of experience about its harm on "people's science" As far as my side... well no one cares about science that much

faisal.97 : Superfluidity is far-out stuff. Yeah, exotic states of matter with no resistance, On that note I just read the other day that scientists created the coldest place in the known universe in a lab. In an area the size of a small refrigerator. Like a percentage of a degree above absolute zero I think. Which is kind of cool. Cold. Very cold. lol.

Yunimori : But isn't the frequency so high that most humans can't hear the cry?

Anyway, random fact of the day: mercury freezes at -43 Celsius. It may look unimportant, but regions that get much colder than these temperatures need better thermometers if they want accurate readings! Most alcohols freeze at -72, making the readings easier. If not, there are now satellites!

Ferdinand : very very cold haha. I think if they can make that process more efficient, then we might see some strides in that stuff where... state of matter get really fuzzy with quantum mechanics. I read in wikipedia that this is Condensed matter physics. Maybe those bose-einstein condensate and fermo-someone condensate are part of that physics. Cool eh?(very very very cool )

Random science fact of the day from me: (and since english doesn't have a "plural you", my usage of the word "you" henceforth is plural for the post. Ye might find the previous statement.. unnecessary.. Yes I just did a joke if you got it )

Get same mass of steel and... spider silk. Then test their tensile strength, fairly(i.e. the technical stuff like test is based on weight and that diameters should be same for steel and spider-silk- I am guessing they made wire or cylinders of these materials to test). You will find out that spider silk is.. 5 TIMES stronger than steel. While a healthy bone is 3 times stronger than steel.(It would be great if minecraft had a feature to make armor pieces out of spider-silk... It would be a good feature..[without making it OP. Like making it somewhat weaker than diamond armor pieces but making it a bit difficult to get like lots of spider eyes] Maybe add the slow effect to anyone who ends up attacking?)

Do you know about the plastic inspired by spider-silk(and that is one of the reasons why don't even need to harvest spider-silk)? If you do, do the obvious

If not then if I get time tomorrow, I shall post it as that day's fact of the day(Btw I have another ready in case you did answer my question)

As for from where I got my fact, it's in my chemistry book... named Chemistry. Actually it is Cambridge CIE AS and A level Chemistry Coursebook by Roger Norris(Chuck Norris's dad?) Lawrie Ryan and David Acaster but the name is too long! Page 486 is where the stuff lies with the question's answer. I seem to respect the book's authors and the book so I posted the source.

Have a good full day

Wow, whoever made this thread deserves kudos. I've always wanted a place to post and read facts.The reason why there isn't any sound in space is because sound can't travel through space, the sound waves need a medium to travel through. Sound is able to travel freely on earth since the air acts as a medium in the atmosphere. 
The weight of entire Internet in 2011 was about the weight of a strawberry (50g or about 2 ounces) or possibly the weight of a grain of salt according to recalculations. The Internet has weight because the Internet runs on electrons. This makes a 50kb email weigh "two ten thousandths of a quadrillionth of an ounce". We share 50% of our DNA with a banana. This is because the 50% holds basic information that is essential for cells. Examples of this include, catabolism, a handful of anabolism data, a lot of DNA metabolism info, transcription, DNA replication and translation. 

The beginning of an era... ‘Wireless’ communications took a giant leap forward in 1962 with the launch of Telstar, the first satellite capable of relaying telephone and satellite TV signals.

ONE WEEK from today, July 14th, one of my childhood dreams is scheduled to come true when the New Horizons space probe makes its closest approach to Pluto. I was in pre-school when the Voyager probes explored the Jovian system. Then when Voyager 2 flew by Saturn I was still too young to really understand. But in 1985 and 1989 when it explored Uranus and Neptune I was beyond excited. Actual new worlds being seen up close for the first time ever. I remember seeing that big blueish-green ball with the rings going the wrong way on the cover of Astronomy magazine and just gazing in wonder. And the moons were actually the most interesting. I hope some of you younger users take the time to follow the mission. You'll likely not see anything like it again in the near future, if ever really. A new world. So much to learn. And they say that it's really just the inner boundary of a whole slew of undiscovered objects in the outer solar system so who knows? Maybe planet ten is still out there somewhere...well, planet nine now.

I'm hot. Let's talk about sweat. Did you know that hippos sweat red? Apparently it helps screen out harmful solar rays and also contains a natural antibiotic. All humans have their own unique sweat just like a fingerprint. AND last but not least... in experiments women have judged the sweat of non-meat eating men to smell better that their meat loving counterparts. Go figure.
