Ah - you're right, TJ. Gord has closed himself off into an impenetrable cage of bananas.

He'll never again know what the hell we're talking about and we'll never again know what the hell he's talking about.

I don't believe it. All you have to do to test it is use 'lay' incorrectly, and Gord will paint it red and type 'lie'.

I bet he can do it in his sleep, even when dreaming of donuts and sammiches.

Two thoughts remind me of other videos.

First, Professor Ed Copeland talks about primordial black holes:

https://www.youtube.com/watch?v=gs3mtZPySeM

Second, this new SciShow video about dark matter:

https://www.youtube.com/watch?v=1pq9hovXI44

...I guess I'll include this one, although I thought I'd posted it somewhere on the forums before (but can't find it now):

Two black holes, some 3 billion lightyears ago…


BH1: Do you believe that there will ever be time travel?

BH2: Well you can never tell for sure, but maybe a few billion lightyears into the future away, some entity, somewhere, may be able to see us.

BH1: I like your way of thinking, and I was meaning to suggest… I mean, if I`m not being too fast at this… Do you think we could merge, and experience that fleeting but deep gravity-wave inducing orgasm?

edit... fixed for old wiseman Gord.... :oldman:

Phew!....OK. So there are (or maybe) primordial black holes, from the time of the big bang. Black holes evaporate at different rates depending on their size. Therefore after 13.7 billion years, there should be a particular remaining ratio of different size primordial black holes in the universe and these may contribute to what we call dark matter.

That makes me wonder.....if primordial black holes are evaporating ......and these same black holes contribute to dark matter, doesn't that mean the amount of dark matter in the universe is reducing?

Light-years are units of distance, not time. :beee: It's like saying you made the Kessel Run in less than twelve parsecs. (A parsec is about 3.26 light-years [ or 31 trillion km / 19 trillion miles ] in length.)

Matthew Ellard wrote:That makes me wonder.....if primordial black holes are evaporating ......and these same black holes contribute to dark matter, doesn't that mean the amount of dark matter in the universe is reducing? [/color]

I don't know, so I'll refer you to this: https://www.quora.com/Is-the-amount-of- ... decreasing

Frank Heile, Physicist, SW Eng, Consciousness & Spirituality Author
Answered 17 Nov 2014

The density (grams per cubic meter) of both ordinary matter and dark matter are decreasing as space expands. The ratio should be approximately constant and the amount of dark matter (or ordinary matter) in a comoving volume should also be approximately constant (see Observable universe ). However, it is possible that dark matter could decay with some very long half-life and it is also possible that dark matter could self annihilate when two dark matter particles collide. Some of the searches for dark matter are looking for dark matter using these effects. Finally, it is possible, but unlikely that additional dark matter could be created by the high energy collisions of ordinary matter. For example, one of the searches for dark matter was to see if the LHC could create dark matter particles when high energy ordinary matter particles collide. So far, all these dark matter particle searches have not observed any dark matter particle yet, so it is likely that the overall amount of dark matter is approximately constant.

The overall best guess is that the total amount of dark matter in a comoving volume will be approximately constant except. On very very long time frames it might slowly decrease as it annihilates or decays.

...even though he is a "Consciousness & Spirituality Author". :shudder:

If dark matter is composed (at least partly) of black holes, and if black holes are able to completely evaporate (and don't stop evaporating when they reach the planck length), and if a significant amount of those black holes were of a size that would evaporate faster than they would accumulate new mass, then it is possible that the amount of dark matter in the universe is decreasing over time.

However, if dark matter were decreasing, it would be turning into something non-dark that we could detect. And in the video, Professor said it's the black holes with "a mass bigger than 1015 grams" (about the mass of Mt. Everest), which will not yet have evaporated, that in principle could act as dark matter candidates. He speaks of black holes with masses of 1020 to 1026 grams as those candidates.

Rewatch the first video from around the 8:23 - 9:00 to see what I mean.

I am struggling a bit here. If I say something stupid, just say so.

A black hole evaporates due to quantum mechanics, in that near the Schwarzschild radius, something (photons? electrons?) will tunnel outside the Schwarzschild radius and escape, thus the black hole reduces in mass.

Doe anyone sort of know what the nature is of the things that escape? Is it a variety of things? Am I correct in assuming it's only photons and that's why we see the huge electromagnetic pulses when blackholes collide?

A black hole evaporates through Hawking radiation. Quantum particles pop into and out of existence, one particle and one anti-particle which then annihilate one another resulting in a net balance of nothing ultimately having been created or destroyed. They aren't real particles, they're virtual particles, which exist only for short periods of time and with the final end state consistent with all the known laws of conservation of energy.

At the event horizon of a black hole, one of the pairs can fall into the black hole while the other remains outside. When you get two pair so particle/antiparticles popping into existence, the particle from one pair and the antiparticle from the other pair can fall into the black hole while the antiparticle from pair #1 and the particle from pair #2 remain outside of it. It's when those latter two come into contact and annihilate each other that you get the creation of two real photons, which appear to be radiating away from the black hole.

But that creation isn't free, and the energy for those two photons must come from somewhere. The energy comes from the black hole, thanks to the particle and antiparticle that fell into the black hole.

This is only possible in severely curved space. The size of the black hole is the factor that creates the severity of that curve -- smaller black holes are more severely curved than larger ones.

And furthermore, quantum mechanics! (In other words, I don't understand it either. If I thought I understood it fully, I know I would be wrong.)

Thank you Gord. I think I now "get it" and see my original mistake. I was thinking of normal atoms or photons escaping which was just wrong. The loss of energy from the black hole means there must be a loss of mass.

On slingshot.

Bobbo is correct that the object moving out again slows down. Yes. But is slows down less than the extra speed it gained.

The extra speed comes from gravitational drag. If a planet rotates in 8 hours, for example, and a space vehicle shoots down to loop around it, in the same direction as the rotation (which is important!), and in an orbit slower than the 8 hours (easy to do. Just shoot around it at a suitable distance, so it takes longer than 8 hours), then the drag of the planet's rotation will accelerate the space vehicle.

This happens with Earth's moon. The Earth rotates in 24 hours. The moon orbits in 28 days, in the same direction as the rotation of the Earth. The gravitational drag of the Earth pulls at the moon, and accelerates it. That makes the moon move faster, moving it a little further out each year, making its orbit longer. That longer orbit means it takes longer to go round the Earth. This is why the moon moves further out and has a longer orbital time every year. Over millions of years, that has become very significant. The energy to accelerate the moon comes from the rotational energy of the Earth, which means the Earth is slowing down in its rotation. Our day gets gradually longer as a result of speeding up the moon.

If you fly close to a planet against the spin, you will slow down: that is what the solar probes did to get into a close orbit.
