Colliding Binary Neutron Stars

[D4NI3LGONZALEZZ]

im learning about stars haha and i have a question? cant the two stars also combine into 1 huge star?

[GatorFreak100]

I don't know that Neutron Stars would create a Black Hole if they collided. Sure, Gamma Rays usually do signal when a Black Hole has been or is being formed but from what I know, Black Holes are formed from hypernovas.

[futiniano]

Ok. The universe scares me more than the exorcist, the ring, the grudge and the zombies at the same time.

[sadathusain]

chuck norris packs more power in one finger.

[canikostar99]

is this an animation cause it almost looks like one even so it still looks cool

[MrsTwilightAddict10]

i was searching. you were on a mission. then our hearts COMBINED like a NEUTRON STAR COLLISION. :)

[selraith123]

guys correct me if im wrong but there's actually energy being created by fusion in a neutron star right? when the protons and electrons merge together and become neutrons

[DieFatorLiveThin]

@selraith123 the energy is not due to conventional fusion. Neutron stars are fueled by the fluctuation between high then low energy quantum states due to neutron degeneracy pressure.

[wexoni]

And this if GRB... hopefully not aimed to Earth

[Paterson212]

Ooooh, purty *dazed smile*

[thecheaterdude]

I've read this would more likely create a carbon star and not a black hole if two neutrons collide..............

Random fact: in 100trillion years there will be no hydrogen stars and the universe will be at absolute zero in teperature.....except where carbon stars are

[Forrester]

@thecheaterdude

Carbon star? A neutron star has so much gravity that the weak nuclear force gives way and only the strong nuclear force keeps to star up. Weird thing is, the more mass the smaller the star at this point. So either the two stars would collapse into a black hole if the strong nuclear force gave way, or would become a single, smaller star.

[lapfuwong]

@Forrester true, if black holes merge together the strong GWs will rip things into pieces and turn them ''upside down''

[tyebillion]

OK, it might be unlikely to happen, but what would it look like if 100, or even 1000 of these things collided at once?

[legitimateJunkiee]

well you have just created the fantasy of my suicide.

[cladiax1]

wont the gravity and density from a neutron star just rip bothe of them apart befor they colide?

[poseidonrox95]

neutron stars colliding are like people. if one adult an a child grab arms and spin each other, the child would spin and the adult would be stationary. this is what the sun does to earth. but, if there were two people of equal strength doing this, there would be a point when they would both be spinning, thus simulating the neutron star.

[VafleTheMan]

Say that a gamma-ray-burst from a hypernova 100 lightyears away from us, is heading towards the earth. The results would be dramatic. The entire planet would be sterile so to speak.

However, if gamma-rays travel at the speed of light, there would be no way for us to predict it before it hits us, right?

So thats every reason to start living right now! :)

[knowledgeis4me]

the chances of it being pointed directly at us are slim though. and if a hypernova occurs within 100 light years of us, a grb would be the least of our worries ;D

[HotRockx]

the gamma rays can also modify our DNA this could upgrade our consciousness!!!

[Penguinz13989]

or kill us all :D!

[NoSz4]

@vafle - Just like light though, it only travels at its constant when in a vacuum.

[mRRRc]

hm... so light travels more slowly in i.e. air? Material should slow down the light? That cannot be true....

[NoSz4]

Yes it is true, to find out how much you look at the 'refractive index' of a material.

[blazednlovinit]

@mRRRc

thats how lenses work. uses Bose-Einstein Condensate they have slowed photons of light down to something like 30 MPH. i've heard they can even stop them but would have to read up

[Penguinz13989]

do black holes ever dissapear?

if they do, does that mean quasars can dissapear too?

[Smurfkiller921]

Quasars are super massive black holes feeding. And yes, black holes eventually evaporate.

[C4nn0nF0dd3r]

through hawking radiation? that qould take longer than we could calculate

[HotRockx]

haha good question

[BajanCreation]

well truly u are a person who loves this science. I can see that as u exude a special passion for it. thats great "love what you do." I guess i should expect great things from you. take care dude.....

[killdozer777]

real sucky explosion...

[Gatenaut]

what energy! kaboom new stuff is born

[BajanCreation]

hey im no science guru but someone respond to this if it makes sense: the sun is a giant neclear reactor, in such a place fission takes place. protons and neutrons collide resulting in neutrons being formed (assuming). Now, if the sun were to run out of fuel would it not turn into a neutron star, and because of its size and the fact that neutron stars have a great gravitational pull, could it pull all of the planets into its mass resulting in the collapse of our solar system.

[1czelaya]

First of all, fusion is occuring in the sun not fission. Secondly, the sun does not have enough gravity for degenerate nuetron pressure to even occur-the sun will not become a nuetron star. The sun only has enough mass to become a white dwarf. Even with all the mass the sun has-just bc it evolves into a more dense object deosn't mean its gravitional pull on satellite objects becomes greater-no mass is created. Any basic atronomy book which involves basic algebra can explain this in great detail

[1czelaya]

Hope that helps.

[BajanCreation]

thanks for the information, lol......u must think im a total science noob......and yes i am...but this caught mu interest. Are you one of those involved in the science of the stars and if so do u enjoy it?

[1czelaya]

I'm a chemical physicist(Ph.D graduate student). I've taken General Relativity, Quantum Mechanics, Classical Mechanics, Astrophysics, ect.... . Yes I find theoretical physics highly enjoyable once you understand the abstract math. However, you dont have to be educated in advanced mathematics or physics to enjoy extreme astronomy in general. There exist a plethora of books for the average audience(non science) to enjoy the basic conclusions and theories in physics. It's a facinating field.

[BajanCreation]

chemical physicist...what exactly do you do. Sounds really advance and Ph.D as well, u seem to be a scholarly person. Do you post your articles/findings on the web that i can read some of your content?

[1czelaya]

Scholarly.... well not really. I'm about as average as they come. Chemical physics/physical chemistry is the application of Quantum Mechanics(relavistic & non-relavistic), Thermodynamics, Statistical Mechanics, Kinetics, Electrodynamics, Molecular Dynamics(Classical Mechanics) and Mathematics(group theory, operators,... ) to understand and predict chemical dynamics. The majority of is mathematical and encompasses advanced physics. Just to clarify I'm a graduate student working on my Ph.D.

[HotRockx]

WTH did you just say? :s

[cek100]

does black hole form from this??

[JABUUTY671]

This is cool.

imma use a clip of it and edit it for my new intro's

[maureenOWW]

Does anyone have any idea of the orbital velocity (around the common centre of gravity) of an average-sized neutron binary just before they coalesce? It would save me trying to work it out...

[muledeer1976]

42.....

[maureenOWW]

42 what?

[Jarls]

Sigh.

[maureenOWW]

42 sigh? Eh? I was wanting a figure in KPH, not annoying ejections of air.

[Jarls]

I was sighing at your apparent naivete regarding the number 42.

Might I suggest a few google searches.

[maureenOWW]

LOL hmm, perhaps, being a human being over the age of 5 (and british) I am more than well aware of the cultural significance, and my apparent ignorance was (perhaps) an attempt to ridicule sure a piss-poor attempt at humour.

It might have been funny if there was a mention in the book of colliding neutron stars, but there isn't, so it wasn't.

Now, can you answer my legitimate question please you obtuse cuntflap?

[Jarls]

Attempting piss poor humour through the medium of written text is never wise, as you have so deftly demonstrated.

And you further demonstrate childish behaviour by reverting to body-part insults. As such, you are not worth my time. Perhaps when you mature a little you will understand.

Good day to you.

[Penguinz13989]

Really, because I found it was quite funny.

[LemmingsMaster]

Hey BarleyPrincess, have you seen a video clip of the collision of a star like the Sun and a blue star, both still burning hydrogen? The sound and everything is cool. Although the blue star is smaller, and stars don't come to an end when they collide if both are still burning hydrogen. The real results are less interesting. Although not coming to an end gives stars 100+ times the mass of the Sun a chance to form. Anyways, have you seen that clip of 2 colliding young stars?

[lymph12]

this animation neglects the fact that Neutron Stars spin pretty rapidly

[brandeezy108]

@lymph12 i thought magnetars don't spin that much? i thought it was only pulsars.

[pektotyou]

they dont look like nuclear bombs

dork

[markjscottfilms]

The gamma radiation that the Americans thought came from Russians testing bombs on the dark side of the moon, was eventually discovered to be radiation eminating from supernovas on the edge of our universe. We can detect these explosions when the gamma radiation eminating from either the top or bottom of the star cosses paths with the earth. Neutron stars were the initial thoery but were disproved.

[FatalFist]

They haven't been "disproved" that's when they were confirmed. A star that's magnetic poles spin so rapidly due to high levels of density.

[markjscottfilms]

Pardon me, it's very complex this subject. :)

[madeworld]

That is wrong, it is because of it's gravity it weights so much. 1mg does not weigh as much as you're reffering to. Get your facts right, and yes, it does weight quite a lot actually.

[thebigguns51807]

NO RESON TO BE A SMART @#$%&*! this is youtube not a scientific buliten!

[DivBMesa]

1 mg of the neutron star weights several billion tons

[flip9388]

both mg and a ton are units used to measure mass....CONSTANTS....the X amount of mg always equals Y amount tons

idiot

[DivBMesa]

haha, sorry I chose wrong words. I meant that even a pin-sized part of the neutron star weights several billion tons, excuse me

[thebigguns51807]

GBR radiation is the same type of radiation from a nuke.

[FatalFist]

Correct. Which the discovery of these pulsars, America nearly went to stage one red alert because they thought Russians were testing nuclear bombs in space.

[ANACONDA360]

which is one of the reasons why Nuclear-powered Rockets wern't to be used...event though they were theorised to significantly faster.

[mepea09]

A gamma ray burst is the brightest, most luminous even in the universe since the big bang. They are created when matter is warped into energy from the spin and gravitational pull of black holes. If one of these ever hit earth, it would end all life as we know it.

[vinnypappy]

that was kind of funny to watch. lol i wanna see it again.

[majorvoltage]

Wow, these must emit gravity waves like a sombitch, assuming gravity waves exist.

[tiredoftypical]

there would be no sound in space though. ;)

any idea as to how long such an event like this takes place?

[swordfighter3]

there are about 400 gamma ray bursts a year, but they happen in a millisecond or several minutes, only you can see the afterglow or its light from earth by telescope(must have a very strong telescope), you need hubble to really see it, maybe one day hubble will get a lucky hit at an gamma ray "line"

[AnduinX]

Fuck yeah, awesome birth of a black hole right there

[swordfighter3]

or a quark star

[aztrance123]

FUCK YA! that was so sic, there should have been sound effects to go with vid

[swordfighter3]

theres no sound in space btw

[aztrance123]

I mean for the vid just to make it more interesting. Realy theres no sound in space hmmmm did not know that

[swordfighter3]

theres no sound in space because sound needs air to travel, and theres no air in space

[aztrance123]

thats cool

[Lastesina]

There is sound, just that you need special instruments to hear it....

[korteksi]

Swordfighter3: Sound doesn't need air - any matter will do as long as it's dense enough for the wave to move.

[FatalFist]

AKA, a medium... but no there is no sound in space. It's energy in the form of Xrays, which is a form of light that is then compressed or transformed into sound... not during. It's a quite complicated process if you want to get technical but rest assured, in space no-one can hear you scream... even if you're dying right next to your partner :P

[Iztaru]

Such an event will release matter as shock waves that affects other matter in their road and our ears happen to be made of matter :-)

But...the impact will not only make your eardrum to move but will also vaporize you!

[peteq1972]

so the two neutron stars collide but the mass combined is too big for a neutron star to be stable. its mass is too great and gravity takes over and it collapses inward indefinately untill it disappears altogether leaving nothing but a scource of gravity so strong not even light can escape. space is wierd :\

[AnduinX]

That's an unproven theory actually. If black holes exist there is no way we can know if they have 'infinite' density or not. Just because they can compact the neutrons does not mean they can compact them to an infinite density. We know extremely little about black holes.

[Evilshonen]

Colliding neutron stars reach the speed of light and faster.

[gordongate]

3 times a second (3 Hz) for a rotational period is pretty slow. Some neutron stars have a rotational period of kilohertz (1000+ rotations per second) there are some sites on the net that have taken the frequency emmissions and converted them into an audio signal, go listen,

[saveyoshot99]

is there anything bigger (explosivly) than a gama ray burst in our universe?

[peteq1972]

no. weve seen then in other galaxies, but its bad news if one goes off in our own galaxy.

[swordfighter3]

400 go off in our galaxy every year(but incredibly rare to hit the earth), watch national geographic to know more abnout this stuff

[swordfighter3]

a supernova is the biggest known explosions in our galaxy, only the big bang would be the grandaddy of them all...

[AnduinX]

I thought a hyper-nova was the biggest.

[goddamitgivemeaname]

take a prtion from the size of a pinhead it would weight over 1.000.000 Tonns(the density is about 1012 kg/cm3 an more!!) imagine landing on that thing ^^ u would be crushed in a second^^

[Jaredster]

Wow, imagine the force of something like that. The pressure at the core of the resulting neutron star. Something that size spinning around 3 times every second.

Amazing

[goddamitgivemeaname]

well its not that "bigsize" only a diameter of 20km

[sh3l1]

it's not about size. it's about mass and these things weigh a lot. force = mass * velocity

[rogan]

Black holes to a supernova? God, really a big msytery to know the universe.
