Hey /sci/,

I got this pic off of /adv/ and I wondered if any of you could explain to me why the galaxy in the last panel shouldn't exist, according to physics.

>> No.1055927

Too large (in terms of distance) for gravity to hold together?

>> No.1055938

Fukkin magnets.

>>1055927
But I always thought that a bigger mass would have more gravity, which would explain why it stays together (considering it has so much fucking mass), amirite?

Gravity's effects decrease with distance.

GRAVITY HAS UNLIMITED RANGE YA JACKASS

Then how the fuck is this possible?

I don't wanna talk to a scientist, them mother fuckers lyin and gettin meh pissed.

Earth isn't in that galaxy, silly goose

So does light, but light's effects decrease with distance, too.

In fact, it might be easier to understand when you compare it to light, considering that the closer something is to an object, the more light hits it. The quantum of gravity is a graviton. Maybe that's the explanation for it.

*shrug*

Regardless, it does decrease with distance.

Gravity does decrease with distance you illiterate cunt. OP, google the inverse square law of gravitation. It is probably correct that it shouldn't exist, but then again it May have an exeptionally large supermassive quasar, or an exceptionally large quantity of dark matter.

>> No.1056286

>>1056081
Or a large super-massive black hole.

>> No.1056325

>>1056286
That's what a QUASAR is. Quasi-stellar-radio radio sources. I.e. Feeding, active, Supermassive black holes

that picture nearly made me cry in awe of the universe.

It's probably just a misunderstanding by whoever made the chart.

Comparisons:
IC 1101 has ~100 trillion stars (400 times more than our galaxy) and has a diameter of approximately 5 million light years (50 times greater) - http://en.wikipedia.org/wiki/IC_1101
Messier 87 is the most massive galaxy overall, at up to 200 times that of ours - http://en.wikipedia.org/wiki/Messier_87
Finally, the largest-known spiral galaxy, ISOHDFS 27, about 4 times more massive than ours, and measured from the Hubble Deep Field your picture talks about (although not actually the particular galaxy pictured) - http://hera.ph1.uni-koeln.de/~heintzma/HDeepF/HD_S98.htm
