Comments on: Black holes growing faster than expected

Maybe, we can expect that black holes and supermassive black holes grow by all of these: endless supplied gas cloud (either poor or rich supply), colliding with other black holes and whatever matters or debris nearing them.

If the sun turned into a black hole Earth’s orbit wouldn’t change at all.

I guess it’s another of those unfounded fears. If we bubbled off the brane in must be much larger than our universe. They gotta have some super massive space heaters over there. I’m particularly fond of the parabolic type that’s glows red. Maybe they’ve got one a few lightyears across!

White dwarfs.. for the most part (main sequence)… to join the small fraction of baryonic dark matter aka MACHO’s as compared to WIMP’s (I’m NOT making this up, lol)

One way to survive into the era of the cooled down universe is to become a Dyson’s Eternal Intelligence.
But this one is not really *eternal*, as its mental function eventually become so slow, and the hibernation periods become so long, that it can be considered no longer living.

Doesn’t M-theory mean heat death of the universe is not a concerns?

Since we time travel, since our universe bubbled off membranes we should be able to get back there?

I’m not sure a large space heater wouldn’t work.

@Eldras: Nahhhh! The only thing to worry about is the ultimate heat death of the universe. My suggestion, a very large space heater!!

Get back to us in a few years and let us know how it’s going.

If you want to worry about “black holes”, you can worry about the undetectable (until too late), tiny (maybe even smaller than the sun), erratic ones, floating around.

Call them the boogeymen, for completeness.

Well I believe our thoughts generate the reality,so if you think hard enough you will succeed in having a BIG BAD BLACK HOLE eating us all ALIVE!!!

In my curiosity, I googled that black hole, and wikipedia revealed the following:

“later observations showed it to be at least 15 times farther away.”

So that makes it even less of a thing to worry about ;)

Could this new discovery shed light on how we can build a *Blackhole Brain*?

I used to worry about a lot of things when I was younger.

Rarely do I find myself worrying nowadays, though. And that’s just as well, since it’s not good for anything. What measures will you take personally to secure yourself against growing black holes? Remember that space is very vast, and we’re 1600 light years away from the nearest one (that we know of). We’ll be post-singularity before we need to deal with it.

All you should do is have your heart-healthy glass of wine, and definitely not worry.

This article says nothing of magnetism but if you really wanna know, magnetism being an electromagnetic wave will gradually lose intensity close to such a gravitational well, just as it is “black” because no light is escaping. (Thus the article couldnt talk about it even if it wanted to)

However, due to time dilation this would take an infinitely long time from our perspective even as all the matter has already been ripped apart past the horizon. Thus you can never see any “packing” even though it’s worse than packed, it is “degenerate”.

Magnetism, say from a hydrogen cloud if it was packed enough to become metallic hydrogen, would “dim” (technically “red shifted”) forever as it falls into the well.

But dont worry, this is all fiction because human models break down quickly after, they simply do not have a clue what this is.

ARGGGG! I built an Andersen shelter for the coming Russian invasions and bombs,
Stocked up with food in the 60′s because the ice age was coming,
Got ready for apocalypse because of the prpphesies of Nostradmaus in the 90′s.
Turned my systems of to prevent the millennium bug in 2000.
Didn’t have children because the earth couldn’t feed 5 billion people.
Worried about the ozone layer.
Shivered nervously about global warming until the southern ice caps started growing.
Gathered with my food supplies on the mountain last december for the Mayan prophesy was due, clutching “The Singularity Is Near” and a crucifix.

-Do I have to worry about black holes eating everything ?

Tell me??

ok As far as I understood earth and other planets produce a magnetic field by having a big iron melted ball in the core that rotates or anyhow there are layers of melted matter that rotates.
I have no problems with that but my question is what creates a magnetic field in a black hole? I mean this thing should be so densely pack that one can’t have moving things inside? the only thing that it should produce should be the gravitational pull but the why not all galaxies are spherical?
thanks for any clarification.
