NASA Uncovers Millions of New Black Holes

Soulskill posted more than 2 years ago | from the enough-for-everybody-so-please-share dept.

NASA 77

coondoggie writes "NASA today said its Wide-field Infrared Survey Explorer satellite has unearthed a 'bonanza of new-found supermassive black holes and extreme galaxies called hot DOGs, or dust-obscured galaxies.' NASA said the latest discoveries help astronomers better understand how galaxies and the behemoth black holes at their centers grow and evolve together." The news was released in a press conference, and io9 has a comprehensive write-up about everything that was covered, including the Q&A session. Pretty pictures here.

Google voice search is racist. If you ask "show me pictures of white people" a bunch of thumbnails of white people show up. If you ask "show me pictures of asian people" a bunch of thumbnails of asian people show up. If you ask "show me pictures of green people" a bunch of thumbnails of green (coloured) people show up. If you ask "show me pictures of black people" all you get is a text only Google search result.

Hi different anon here - while my fellow anon poster may be crass in making his point - it still stands. It doesn't seem overly PC to you? To me it seems like the kind of overly PC move that actually legitimizes and maintains the racism it's attempting to overcome. After all, if "black people" are just like all other "people" why can I search for pictures of other groups, but "black people" are a special case? If no one cared, it wouldn't be an issue. Eventually someone has to be the bigger (wo)man, or the problem never goes away.

Re:Stellar+ black holes coldest thing in universe (1)

msauve (701917) | more than 2 years ago | (#41178381)

You're referring to Hawking radiation, and of course that only applies to the temperature as measured externally. What's the temperature of your refrigerator? Mine's a bit above 0C, but I can't measure that externally. Similarly, the event horizon can be viewed as an insulator, so what is the internal [technologyreview.com] temperature of a black hole [worldofweirdthings.com] ?

With a covering (accretion disk), the externally seen temperature is much higher, in the millions of degrees, hence my comment.

hansraj (458504) | more than 2 years ago | (#41172323)

A black hole would dissipate via Hawking radiation only if it doesn't absorb more energy than it emits. Large blackholes absorb more energy (cosmic background radiation) than they would emit and hence will not necessarily dissipate. From wikipedia [wikipedia.org] :

"A black hole of one solar mass has a temperature of only 60 nanokelvins; in fact, such a black hole would absorb far more cosmic microwave background radiation than it emits. A black hole of 4.5 × 1022 kg (about the mass of the Moon) would be in equilibrium at 2.7 kelvin, absorbing as much radiation as it emits. Yet smaller primordial black holes would emit more than they absorb, and thereby lose mass."

Missing mass of the universe? (2)

It sounds like they just found a lot of 'missing mass' here? How does it jibe for balancing things without using 'dark matter/energy'?

Re:Missing mass of the universe? (5, Informative)

Chris Burke (6130) | more than 2 years ago | (#41172965)

How does it jibe for balancing things without using 'dark matter/energy'?

Not well.

These SMBHs are in the centers of galaxies, and piling up more mass at the center of a galaxy doesn't explain the problem of flat galactic rotation curves. The mass needs to be in and surrounding the galaxy, which is why the non-exotic DM theory is called "MACHOs" as in MAssive Compact Halo Objects -- because it'd have to be in the halo.

It's even worse for Dark Energy, since extra mass would actually have the opposite effect that DE has, pushing the universe closer to the Big Crunch scenario. It certainly would not explain accelerating expansion.

Re:Missing mass of the universe? (1)

AwesomeMcgee (2437070) | more than 2 years ago | (#41173039)

Depends on what a "lot" of missing mass is, that's relative to the amount of mass there is. We can't know how much mass there is, that might be a missing spec in the grand scheme of things.

Re:Missing mass of the universe? (4, Interesting)

Smauler (915644) | more than 2 years ago | (#41173827)

It doesn't. Basically the reasoning for dark matter is this :

Under Newtonian or Einsteinian physics, galaxies should rotate a lot slower on the outside, and quicker in the middle than than they actually do (a little like our solar system behaves). No one can explain why they do not, satisfactorily yet.

Dark matter is an explanation which proposes that there is undetectable matter causing the gravity interference which does explain the mechanics of galactic movements. Trouble is, we haven't got a hold of dark matter yet, so although it's an explanation, it's not concrete by any means. If you want a definite explanation, you're probably going to have to go to your priest.

Black holes don't fit. There aren't that many black holes, and despite the name, they are observable. If there were enough black holes to cause galaxies to rotate like they do, we'd have seen them already.

Taibhsear (1286214) | more than 2 years ago | (#41178597)

Perhaps someone knows... The more massive the gravitational field, the more time dilation, yes? The farther out you go the less drastic the effect is. Could the rotation just appear (to our frame of reference) to be moving not as fast in the middle (where the gravity is strongest) even though it is moving as it should according to our theories?

IINAP (and I'm guessing you're not, either). I used to think of things like this and say, "gosh, couldn't this be the explanation?" Then I remember that there are thousands of experts in the field, and it is extremely improbable that me, a layperson in the field, has thought of something -- especially something relatively (pun intended) simple -- that an expert hasn't thought of and obviously debunked (because we would have read about it were it plausible).

That said, I don't understand the physics behind gravity wells and their relation to time dilation very well, so I would be interested to hear from one of the aforementioned experts why it's not as simple as Taibhsear has made it sound!

Well, if this was the case, then we would see the same effect in our solar system -- both in the orbits of other planets, and in the orbits of moons around planets -- and they too would show flat rotation curves. However we do not, and both show decreasing orbital velocity with increasing distance from the sun in very close accordance with Kepler's Laws.

The upshot is that the time dilation effect is extremely small compared to the amount that velocity will drop off with distance from the primary concentration of mass.

drkim (1559875) | more than 2 years ago | (#41174727)

They can be found in a number of ways...

They give off something called Bekenstein-Hawking radiation because they are sucking up half of spontaneously generated particle pairs - leaving the other half (that would normally disappear back into the sucked up particle) to spray out into space.

They can be 'seen' by the gravitational lensing they produce when you try to look at the background behind them. (And most of space isn't black, it's full of bright objects and lots of microwave radiation.)

...and, of course, their presence can be measured by looking for their strong gravitational pull on instruments and objects around them.
