NASA | GLASTcast | Episode 2: What are Gamma Rays?

[RobinahJ]

Man, this is amazing. Beyond all the wars, and hunger and cries of the innocent, the world is beautiful and amazing beyond all measure :D

[tahnounbintaj]

thnxx the Subtitles really helpd alOOt :P.. hoping for more :D

[AhmadMaazAli]

i need the uses of gamma rays,can any one help

[TENspeaks]

@ vlatin1 - gamma ray bursts don't originate from within the black hole; They form after the collapsed star exhausts its energy/matter. After the star has exhausts it's energy; a black hole forms.

My questions: Are the streams of light from the collapsed star quasars? Are quasars gamma rays? I didn't think gamma rays were part of the visible light spectrum.

[vlatin1]

So apparently, astronomers will use GLAST to study how black holes accelerate jets of gas outward at high speeds. Wait a minute, when mathematicians invented these infinitely dense point-masses, we were told that nothing could escape a black hole once it has crossed the event horizon. So how are these magical jets accelerating out of a black hole? I thought gravity was an attractive force. Hey NASA, you know what, we live in an Electric Universe, not a gravitational universe.

[GateMessenger]

I'm guessing, maybe the GRB is an illusion which forms when we are disconnected from the distant galaxy's EM field? For instance, if light cannot travel faster than c yet the inflation between 2 galaxies grows to just above c the flux each galaxy emitted would abruptly separate, loosing their connection, causing a gamma ray burst containing a representation of the trailing energy & is witnessed in both galaxies. The galaxies disappears from sight but neither explode or loose their mass energy.

Until I looked at the comments for this video, I was incredulous to the success of Nigerian Internet scams. I can claim no such thing, at this point. Thank you.

[chunkmanshaun]

TESTICALS!

[avinablast]

@kirox77 No! Nothing is gunna happen in 2012.

[avinablast]

[pillowbugg]

Could there still be other unknown frequencies outside of the current electromagnetic spectrum that we know of? lower then radiowaves or higher then gamma rays?

[Onscherpschutter]

is it true that you can hear radio waves send in the 2nd WW, with a radio?

[quangluu96]

can human make gama rays? like gama ray generator?

[Buddyb309]

can we make a Gama ray on earth? other than with a nuclear bomb?

[GateMessenger]

@Buddyb309 Gamma rays can be produced by machines similar to an x-ray machine, see radiotherapy. A gamma ray wave is produced naturally by the decay of a stars electromagnetic field & is the complementary force to gravity, see how the Sun's energy output is balanced by gravity. The EM field flows from a core outward going through all matter, see high energy quantum tunneling. Simply put, for every action there is a reaction, & the reaction to this action is gravity. See my gravity video. peace.

[GateMessenger]

Those who wish to argue this simple concept need to research the black hole in the center of our Milky Way galaxy, Sgr A, & note that several stars orbit it at less than a light year showing a concentrated point of gravity. Then see the gamma ray spectrum images of the Milky Way by Fermi Telescope to see mysterious gamma rays which emanate from towards galactic core & put them together. EM radiation needs to be rethought, see Cosmic Hot Spots article. Even inactive black holes emit EM fields.

[Godsblack]

Nasa should thank Ava kludze for helping them make GLASTcast

[Iambecome]

Mmmmm, that woman at 1.13 is gorgeous. Anyone know who she is?

(And the video is good too)

[NASAexplorer]

She's the Principal Investigator of the GLAST French contribution and works and is a physicist at the French Atomic Energy Commission. :)

[kirox777]

why dont you make a video about 2012?

[matthewgroen]

@kirox777 cuz thats fake

[kirox777]

@matthewgroen well we are about to have a burn a fuckin koran day... i dont think we will live that long. if they attack us we attack back and WWIII starts and there u go...

if 2012 is REAL. nasa is too busy building a rocket with all thier supplies to live on the moon. you think i dont know? they even made a video to say "HA u all will die on earth, and we will like on the moon like this:"

[avinablast]

@kirox777 What? What vid you talking about?

[kirox777]

@avinablast lol im talkin about how they could live on the moon. and if its possible

[avinablast]

@kirox777 Its already 20 years beyond possible, we have the means for most of the tecnoligy that me, you, and the other 15 000 average people that view these channels, but cannot secure the funding, but thats not overall suprising when this gets as i said around 15 thousand hits where as dog runs in circles gets over a million. If i was nasa, i wouldnt save us either. But i still wanna know what video your implying towards. lol. I love the potential of a conspiricy theory. :)

[kirox777]

@avinablast i just want any type of video confirming or denying 2012 or something

[Extermanat0r88]

@Iambecome eeeeeewwwwwwwwwwwwwwwwwwwwww

[LuxuryBarrage]

@Iambecome I was expecting some hot chick.

[monkeyman5lol]

@Iambecome or not...

[Iambecome]

@monkeyman5lol you don't know a good milf when you see one, sir.

[monkeyman5lol]

@Iambecome SHE IS DENG lol

[GeminiAzules]

An alien armada is moving from solar system to solar system destroying life supporting stars to prevent competition.

Everytime you see a gamma ray burst, its another civiliation being wiped out by its destroyed Star.

[QIQrrr]

Yes indeed.

[RarewareLover]

...its like a christmas tree...

O thanks lady, thanks a lot

[elseve1]

so.... what ARE gamma rays? can you do another video? only this time blow something up. maybe a cat?

[sublime1010101]

do stars rotate around other stars

[mario8eren]

yes

[inthefade]

I good way to think about it is that that two objects always orbit each-other.

For example, Earth and the sun Share a Common orbital point.

The sun is so massive that the point we share is much much closer to the center of mass of the sun than earth's center of mass.

There are binary star systems, where two stars are spinning around each-other, something like two kids holding arms and spinning around each-other. They usually have a very high orbital velocity and are very small stars.

[sublime1010101]

could there be a planets so huge that the animals on the planet are larger than our own sun?

[inthefade]

well it would probably work in reverse. A large planet would require that the animals stay closer to the ground because the gravity would make being tall very dangerous. A smaller planet would have lower gravity, and therefor allow for bigger animals.

[sublime1010101]

but wouldn't they be natural stronger from the environment. isn't that how natural selection works. isn't the size based on how much food is available in the environment? couldn't trillions upon trillions of cells pile on top of each other to make a monster pile of bacteria. i don't think it matters how high of the ground a cell is in an organism. gravity is the same on the ground on the floor as it is on the roof. how would gravity stop the growth of anything....

[sublime1010101]

could there be flouting plants in a smaller gravity environment that live in clouds. that would be something i want to see. could there be a planet that's a ball of water surrounded by oxygen and carbon dioxide that has life in it?

[inthefade]

Elephants are so large that if they trip or stumble they can very easily break their own bones or damage internal organs.

Structures like bones and muscles in our biology have physical limits.

However you're right that a monster pile of bacteria could probably exist in high gravity. They easily live in high-pressure, high temperature volcanic vents on the ocean floor. But complex multicellular life with skeletons or exoskeletons probably wouldn't grow very big in higher gravity. Who knows.

[sublime1010101]

cool

[sublime1010101]

you are so wrong its not funny

well actual it is

dinosaurs were fecken huge.

take a loot at your self, you are a scientist and you relate the largest possibility in animals to a mere elephant. take a look at the movie Jurassic park. take a look a these great sloths. they are like the size of a large tree. larger than most. what if you created the perfect ecosystem and the animals would be smart enough to eat and they would be awesome.

[ojtheomega]

ur an idiot our sun is to massive to comprehend. there cant be living things bigger than earth it's just impossible, since like he said they need to adapt.

[luchoar81]

SUBTITLES PLEASE!

[winterstellar]

They're dangerous. If a gamma-blast ever hits us, we're fried/evaporated/gone!

[mario8eren]

unless we live deep under water ^^,
