Problem is looking at it 2d in photo, is it a sphere of nothingness that sucks everything into or a disc or is it a 4 dimensional object ?

It depends what you mean by "black hole" and 4 dimensions. If it's the volume of space contained within the event horizon, it's a sphere in 3D and in 4D if you're counting time as the 4th dimension. If it's the actual thing itself, nobody knows what it is let alone what shape it is or if it has a shape. "singularity" may as well be short for "haven't got a single idea"

Er, its a sphere of darkness that warps light around it so you'd see a distorted effect as light bends around it. There is usually a disc surrounding it consisting of matter spiralling into it which is ironically often very bright as its emits intense radiation. The rotation of the disc prevents matter from disappearing straight into it as would be the case if it were above or below. The same reason the planets circle the sun in flat plain known as the ecliptic as they're derived from a disc of material as well. It warps the 4th dimension of time the closer you get to it. All objects with gravity warp time but because the gravity is so pronounced in such a small area its particularly extreme near a black hole.

A little more perspective on this historic moment:

5 petabytes of data.

:eek:

Not black enough. It should go live in the 'hood for a while.

I really don't get how a post about one of the greatest scientific discoveries ever has led to so much political correctness bashing, race related nonsense in this thread. :rolleyes:

People think they're being satirical and clever. Unfortunately their black holes are letting no humour escape.

Well, I'm "part black" and my post had nothing to do with political correctness, so it isn't in the same vein as others'. As for humour: guilty as charged.

so what is it?

Has Trump called it 'FAKE' yet?

That's no moon.

I've never seen one before - no one has - but I'm guessing it's a white hole.

Holes of Colour, you filthy racists!

Absolutely stunning, that.

Reading about space always helps ground me, in a weird way. Like, there's so much stuff out there, making us all almost insignificant. When you try and process the numbers in your mind and then think about the small issues that you're dealing with on a daily basis, it makes you wonder why you bothered worrying at all.

A *white* hole?

Don’t know why they went all the way to space for this photo. There’s one in Kolkata.

Or look on here. Plenty of *** holes

todays moon landing will also be impressive

if you heard their guy on R4 today, he was self-deprecatory that it will arrive one way way or another (in pieces)

Just to think it will take 10^67 years for a black hole with a similar mass to our sun to evaporate, this black hole is over 6 billion times the mass of the sun :eek:

It's a big black holey thing in space.

Just standard GD edge lord behaviour, pretending everyone else is always offended by shoehorning political references in to every thread they come across just to get offended themselves.

Is that referring to the amount of data received by the telescopes involved in the project?
