My gut reaction when I first heard this story break was simply 'Giuliani'.

You are saying something I've been saying for years. In fact, it was my parent's generation who I saw anticipating armaggeddon, and they expected it in the year 2000. It's what the lyrics of 'Party Like It's 1999' are all about.

I get the idea that when it didn't happen that way, it surprised a lot of them, and eventually pissed off a bunch of them. They felt like they'd been cheated out of the second coming, or something.

While my parents are passed now, and didn't really share the perspective anyway, I think there are still a bunch of these grizzled old assholes around, ready to see it all burn before they croak, just so they can be around when it happened.

Also Idk what you are talking about nobody believing there's an actual singularity; I don't know what else you think is happening, or of what use the mathematics might be if it doesn't approach some degree of accuracy as concerns the physical character of the phenomena

Thank you for linking that! I knew I had read that they could be, but I couldn't recall where. It might not have been Scientific American, but that'll do XD

While clearly they can be, infinity == infinity is still true, If I recall.

Also, I've got some simple problems with that crate analogy, Scientific American or not; any crate with an infinite number of anything inside it cannot be emptied, it's in the very definition of infinite. Consequently, neither crate will ever empty and the pairing will be an infinite pairing of apples and oranges.

A couple examples of manifolds:

• exhaust manifold on combustion engine takes raw cylinder exhaust gases in pipes that all come down and combine into a single larger pipe that connects to the input of a catalytic converter.
• the plenum in your attic is a manifold. One big duct runs from your air handler into a box with several ducts coming from it, delivering air to each of the vents. the ducts and the plenum form a manifold.

In literature, it means 'many and various'.

In mathematics, "a collection of points forming a certain kind of set, such as those of a topologically closed surface or an analog of this in three or more dimensions"

In Kantian philosophy, "the sum of the particulars furnished by sense before they have been unified by the synthesis of the understanding"

Origins: Old English manigfeald ; current noun senses date from the mid 19th century.

All from the wikipedia

They all have some descriptive relevance, but the one that really counts for us is the math one, suggesting the closed surface.

It wouldn't surprise me though if it still worked; there are many examples of topologically closed surfaces that can still be traversed, if in unexpected ways. I'm thinking of another manifold, the klein bottle, and of course the mobieus strip.

Not even going there right now. It is an adjacent issue.

@FaceDeer

My dude, your logic. Yet somehow, you arrive in the right place.

@kjr

Not helping much here in Texas, though.

It's added by the software, its how everyone gets the replies

By definition, a manifold has a place where things go in, and other things come out. So yes, it does in fact logically follow. If its a manifold, then it logically follows that what goes in comes out.

You're saying we know a bunch of stuff I'm not certain we know.

My understanding is that by definition, the singularity has infinite mass and infinite gravity, so there is no way it can gain mass; because infinity + 1 = infinity. It's the very nature of infinities. You can have a number of infinities, but manipulating them arithmetically always yields infinity. 2 x infinity = infinity. 3 / infinity = infinity.

Like zero, it is more identity than number. 0 = nothing, infinity = everything.

So if you hope to have me follow your narrative, you're going to address this assertion concerning increasing the mass of black holes first.

@anon6789

Me neither guy, and I find it tragic that somehow these fucks that cultivate these attitudes are even allowed in government when really they should be in the jail.

@gk99

@nuke

"They always do" - I'm not talking skirmishes here.

I also do not disagree about the mindset. But that mindset has been well and contuously fed and watered; cultivated

@kjr

can't happen fast enough or cheap enough.

@kelvin0mql

It's possible to draw parallels like that everywhere all over the bible; and it's not because of 'omg prophesy'

@readbeanicecream

I'm no authority, but I love this stuff. I read Dr. Hawking's book "A Brief History of Time", and it was not problematic for me.

My takeaway is that a black hole is a sort of manifold. It would follow that if there is a way into it, and stuff going into it, the stuff must be coming out somewhere.

The question is where that stuff comes out, and in what form, and when, in it's local time frame.

I had always envisioned this hypothetical 'other side' as a white hole. It seems like, since we haven't observed any white holes, that the exits must be elsewhere.

@kelvin0mql

As my dad used to say, "You can't live with a grizzly bear. One of you will have to go."

@nuke

This is exactly how they want you to feel, because it will sensitize you to the violence, you eventually move beyond the mere vocal, and they'll have the war the want, because you and everyone like you will do the same thing. You're far from alone in this thinking, so they are winning on fronts that we dont acknowledge, at least not 'in the clear'.

@kelvin0mql

Lets be clear - I am not making any kind of defense of this guy; I am eviscerating the GOP for creating and sustaining an environment that keeps that guy squarely where they want him, and operate that firehose of falsehood that suck new people into the rotten fold on an ongoing basis.

@kelvin0mql

I do not question any of that. My point is, the republican party has been stirring this pot a long time, and as long as the money keeps pouring, they cant be arsed, as the brits say.

It's got to be stopped at the source. We're already at the point that guys are like this everywhere. One stands in the foyer of the Kroger just about every afternoon 3 blocks from my house.

Wearing a ball cap with a thin blue line flag, armed to the teeth, in a flag-wrapped t-shirt, glaring at anyone who walks by with a smile their face.

His body language, the sidearm he's wearing, his clothes - it all screams that if you're aren't mad as hell and not going to take it anymore, you must be a fuckin' democrat.

That is a feature of the republican party. If it isn't addressed soon, some sort of war will be the only way it gets addressed.

There are a lot of people who would like you to think that disinformation is harmless; that if you buy into bullshit that it's your own fault; and that the 'people that matter' know the truth.

This man bought into the fire hose of shit that is continuously, endlessly spewing a mixture of exaggerations, half truths and outright lies. He took it all very seriously, and he paid with his life.

Ask yourself, do you think this man was one of the 'people who matter' to his family? It sounds like some of them agree with, and listened to him and the fire hose.

This is a fucking tragedy. This man is a casualty of the fight for democracy, and it is a damn fight when people are getting shot for it. Not because he bought into some bullshit; but because he was fed a line of shit by people he trusted. His political party.

This has got to stop, and I think that it surely will.

Let's hope it doesn't have to be at the expense of another man's life.

Another husband, father, grandfather, uncle or brother. Or worse, whole families.
