Nemesis Theory For Mass Extinctions
#1
Here is my favorite pet theory.  It just won't go away.  If you have missed it, its time to check it out.

Complete nonsense. There isn't a 26 million-year pattern of mass extinctions. Extinctions were caused by all sorts of reasons, supervolcanoes, comets, climate change, etc, sometimes in combination. Much more likely than an invisible star cruising out there is a black hole. Everything with an atomic mass larger than iron is produced in supernovas, and they make a black hole in the end. And one of them must still be out there in the neighbourhood, otherwise we wouldn't exist.
We are in the middle of the mother of all mass extinctions. Nothing what nature can throw at the life on our planet, no comet, no supervulcanoe, compares to the unstoppable onslaught of technology.

S13 I'm sure you are correct "Q". S13

Why do you think we are destined to go extinct?

The actual Nemesis theory makes a great deal of sense, regardless what ever "Q", or Ron may say about it. Something of mass is causing a shakeup of the Oort Cloud in certain points around ever twenty-six to thirty million years. The more I think of the "Galactic Plain" theory, the less it makes sense. If it were causing a shakeup every time the solar system moved up and then down across the gravitational plain, the shakeup would be general to the Oort Cloud itself, and cause a significant percentage of comets to lose orbital stability. Too many comets would wind up inside the sun's gravity well at once.

But a stray planet, captured by our sun, could possibly be the main ingredient. But that is more unlikely than a brown dwarf out there, causing all this trouble at steady intervals. Richard Muller is convinced it is a red dwarf, but it seems more likely to be a brown dwarf, which is harder to locate, or tell its movement.

But clearly something is causing all these comets to be shaken loose. And as much as "Q" thinks the number of comets, causing the same number of hits, and killing off the same number of species, is less than improbable. Each cycle would, statistically speaking, be different from the last one, or next one, because while the events may be predictable, the movements and collisions of the comets would be random. In other words, sometimes, the planet may only be hit by one comet, sometimes none, and sometimes several. That is all in the math.

All those volcanic super eruptions are the result of something. And most likely the result is that of comets striking the planet, causing a rippling shock wave around the planet, disrupting fault lines. Anything else just doesn't make logical sense.

Richard Muller is right about human beings having enough time to get their technological selves together to prevent the next occurrence.

Thanks for sharing this show. I love watching this kind of stuff.

I would like to share an added theory. Take the way drgonzaga writes, I believe it adds even more of a gravitational pull to the Oort cloud, and what disturbs me is what happens when drgonzaga and ustrader makes a post at the same time?

I shudder at the consequences. S26HineyS13

I wonder if we can get 'ustrader' over here? That would be a real coup, since the Pit is anything but completely dead. I wonder when whatshisname finally decides to pull the plug? Georgie-Porgie has been here lately, but left in a huff when all the Ron Paul fans(myself included) weren't willing to follow the official GOP line.

Can't you just picture dragonzaga, ustrader, and 'Q', all= residing in one place? Talk about exciting. S5

As for the show, I'm really Into those sort of things. Now, if the folks over at the History Channel, or The Science Channel, would put out a show about the Space Elevator, I would be in heaven.

You have no idea the number of hours I have spent in bed, contemplating how to get one made, and its effect on getting into space. I've figured out where space industries will eventually be placed(Trojan Points) and how the space elevator will be able to slingshot trips to anywhere in the solar system. If I happened to be a novelist, I would have the perfect story line for a nice SiFi series.

The Space Elevator? Right on!

May I suggest a novel written by Joe Haldeman called Marsbound? It has that concept at the beginning of the story.

As a matter of fact he has several cool sci-fi books. S5

Why don't you try to entice ustrader over here?

I doubt you are on his "S" List. S1

I help you because I suspect that won't happen because intelligent content draws too few viewers to American channels, and they can't sell time for commercial adds expensive enough to turn a profit. The socialist BBC doesn't have this problem, they are taxpayer-financed, and can afford quality over quantity.

You might want to look for the other "visions of the future" episodes.

Well, the market forces in play have directed the History Channel to play nothing but Nostradamus, Aliens, Ghosts and Bigfoot as well as pawn shop shows.

How far has it fallen, but eh, got to keep up the ratings I guess. The BBC has some great stuff, and I see that History International has kept up quality because it isn't centered around American audiences so much.
