Fact or Fiction?: Dark Matter Killed the Dinosaurs

We are currently being killed by Half Dark Matter. It resides in the White House.

And bares (bears) an uncanny resemblitude of chaos theory.

[Rightwing Conspiratr1]

They’ve also theorized that the universe is infinite, finite, static, shrinking, and expanding. So when they readily admit that their theories are all based on speculation, I remain skeptical.

The universe IS infinite, finite, static, shrinking, and expanding. The cause of these seemingly wild perturbations in the universe is anthropomorphic global warming. The science is settled. Stop denying it. /sarc

Black Matter Lives!

Black matter isn’t black, but that doesn’t matter.

I have a problem with this theory.

“
In 2014, the Harvard University physicists Lisa Randall and Matthew Reece published a study showing how the gravitational pull from a thin disk of dark matter in the galactic plane could perturb the orbits of comets as our solar system passed through, periodically peppering Earth with giant impacts.

If dark matter forms dense clumps rather than being uniformly spread throughout the disk, Rampino says, then Earth could sweep up and capture large numbers of dark-matter particles in its gravitational field as it passes through the disk. The particles would fall to Earth’s core, where they could reach sufficient densities to annihilate each other, heating the core by hundreds of degrees during the solar system’s crossing of the galactic plane”

However

“Unlike the gas clouds, which grind to a turbulent halt, and the stars, which mostly glide past each other, the ubiquitous dark matter passes through everything and emerges unscathed, like a ghost.”

The concept that Earth wandering through dark matter clumps which can affect Oort cloud objects, fine. The idea that the Earth can capture dark matter? Science says no. It exerts gravitation, but appears immune to gravitation.

[P.O.E.]

Very good!

[Chainmail]

So, this article says that our passing through/near a disc of dark matter every 26 million years or so kills everything off, more or less.

The last mass extinction was 66 million years ago - how'd we miss the last two that should have occurred?

I'm a little concerned with our scientists' math skills...

Well that sure is bizarre and convoluted theory.

[I want the USA back]

The idea of dark matter was invented because their theories didn’t work right. Now dark matter had become an article of faith and it can’t be questioned.

[Boojum]

a density of at least one solar mass per square light-year

Huh???

This was posted earlier but I will repost...... it is a great lecture that is about the synergy of biological and geological change.

Evolution is defined as change over time

[Paradox]

In before the anti-science luddites..

Oh, too late.

[SolidRedState]

I’m going to go release some dark matter right now.

This is about the Oort Cloud, right? So, why aren’t they calling it “the Oort Cloud” instead of just “dark matter”? We’ve known about the theoretical Oort Cloud for years. Not news.

I had just settled in with a big honkin’ mug of chocolate milk to do me some freepin’ ...

ROTB(ed)LMF(reepin)BO.

Chocolate milk all over my phone. I needed a good laugh. You made my day. Thank you, darlin’.

[Pikachu_Dad]

You do not need ‘dark matter’ for such a theory. Ordinary matter would do just fine.

[Pikachu_Dad]

Now, the oort cloud is made up of ordinary matter.

Dark matter has not yet been observed. at least directly.

Yep.... its just garbage theory.

That's racist!

Dark Lives Matter!
