sim'd not shooped

Well, I don't find this particularly interesting, since it's just a black hole consuming it..
It becomes much more interesting when a pulsar or a neutron star is in a binary system with a lesser star.

Good ol' type 1a supernova.

>>4640837
Shut up, figment of the retarded part of my imagination.

>>4640893
Pff.
Type II supernova is best supernova.

It's beautiful. They should have sent a poet.

You can clearly see the black spot. Is this the first time a black hole has been photographed?

>>4640930
I think the picture is a simulated image.

>>4640930
I assume it is a simulation since the event they are talking about in the article is over two billion light years away.

>>4640893
I thought 1a was a neutron star blowing off it's accretion.

>>4640930

>>4640947
Yes, and that accretion happens in star systems containing at least one neutron star and at least one relatively run of the mill gaseous star.

mfw black holes haul ass through space. how would humanity react if we noticed jupiter being devoured by one of these monsters? and what would the gravitational effects be on earth? would it fuck with our orbit?

>>4640965

if it was as close as jupiter wouldn't we already be moving toward it?

>>4640974
i think you have to bump directly into a blackhole to fall in. but i am not really sure how the tidal forces work. wonder if one could pass through our solar system and us not even know it.

>>4640965
Black holes are more massive than the Sun thus the effect of one approaching us would be felt long before it began devouring anything. If it were moving very quickly relative to the solar system such that we wouldn't feel its effects until long before it reached the planets then it would rocket through our solar system and fling most planets every which way.

that would be fucking awesome. maybe being catapulted into the blackness of space and everything freezing? what a horrible fate.

>>4640948
So, how did they know it was a black hole if their data is much less clear to notice great detail as far as that?

>>4640963
Hahahahaaah hahaha, is that the original? How the fuck you determine there's a blackhole there from a small dot of light with enough precision, given that's so fucking far?

>>4640984

depending on the mass of the BH...remember, BHs have a mass of their own, and hell a BH with the mass of the earth would only be something like 3 or 4m in size...as long as the BH doesnt disrupt the gravitational dance our system is currently in we wouldnt notice unless something got too close and passed into the event horizon

>>4641004
Why is that funny?

>>4640947
>>4640964
Correction, type 1a supernova are the fusion of accreted gasses on the surface of white dwarfs, not neutron stars.

>>4641011
how awesome would it be to see jupiter just disappear? there goes our astroid shield. shoemaker levy 9 - 2.0 would get us. (fireballs bigger than the earth)

>>4641017
It's not funny actually. I don't get it how people can believe in the existence of blackholes from such vague data like dimmed light from some distant stars.

We are debating here on earth even on phenomena which are close at hand, like biological processes. But dimmed light in a distant star is considered solid proof of the existence of a black hole... And we call this science. Sorry, but this is a joke not science.

>>4641046
You sound like you know exactly the extent and nature of the evidence upon which we can say black holes exist, and not like a troll at all.

>>4641046
Because that's how the math works out. What's the wavenlength and intensity of the light? What is its duration? If the data matches a model and that model exclusively than its as correct as correct can be.

>>4641063
I don't claim that. But if you show me data which are conclusive enough to allow positing the existence of blackholes, I'll more than gladly consider it in good faith.

>>4641083
> faith
Oh I see now. Get out.

>>4641083
On the topic on the existence of black holes, we predict that there is a point at which matter can be forced together through stellar events where no force could hold its collapse back. We see stars orbiting seemingly empty space. What other evidence would one need?

What's the model that says there must be a black hole dimming the light from a distant star and not, say, a cloud of dust or some other body blocking the light? It could also simply be that the star is losing its fuel so it's getting dimmer by its own lifecycle, not because of a blackhole. There is no similar light distribution in the original data which shows a black dot sucking the fuel from the star.

Also, so many of the "models" about the universe have been proven wrong or inconsistent. Our "models" can't explain much closer phenomena, like why is the temperature in the sun's corona higher than its core.

And people are laughing at biology being a science, or psychology, but we are giving credit to this light-guessing "science", based on "mathematical models". I'm very skeptical about all this.

I guess a space probe sent to the closest blackhole to get more detailed data on its effects on surrounding stars wouldn't be bad.

Can't science.

Take an astrophysics class then come back.

I have met people like you on YouTube
are you one of those Plasma Cosmology people too?

>>4640984
>what is gravity?

>>4641117
Effects? What do you mean? We have no reason to expect anything special is happening in the surrounding space. Gravity is gravity. The gravitational force of our Sun and a black hole of the same mass is the same at a distance.

Don't be dicks. No one knows everything. How about you spend your time mocking people who actually resist learning instead of the people who simply don't know something.
