Big problem with directed panspermia is how to keep spores viable for millions of years traveling through deep space.

Digitized DNA and a 3D printer.

This guest is hard to interrupt. Hoagland gets frustrated and loses his momentum. If he says oooooo mmmmyyyyy ggggooooooddddd like that one more time, I will finish this bottle of scotch and start screaming.
If you're going to stick with Hoagie over the long haul, you've got to pace yourself; your outrage,  your drinking, your sanity, etc.  There's only so much to go around, and there's a lot of crazy Hoagland territory to cover. 

I enjoyed the guest stating up front that he's "not good with numbers", and reached his conclusions about Oumuamua by using "applied mythology".   That's always my go-to approach when analyzing astrophysical mysteries.

Hoagie's rolling tonight.  I'm enjoying it.  Braaps!

You could do it that way with a von neumann probe or the like. I wonder if there might be a time problem there, it would have had to seed like 3.9 billion years ago which would imply a very ancient and advanced civilization existing back then. Assuming it took billions of years for them to evolve and reach that level, they might not have had enough time to get to there due to a lack of heavy elements early in the universe's history.

That’s going to open the door to you know what...

Hoagie is literally orgasmic tonight. LOL

It's that sticky subject of Panspermia. Ewww

"Tonight my guest, Gordon White, and I are going to tackle the sticky subject ofâ€"

Panspermia."

The only probe Hoagie knows intimately is the Falkov Probe, more commonly known as a strap-on.


Such a shame mainstream science ignores these two geniuses, they've got it all figured out. We can move on to other things.

Wouldn't the freezing do that?

The guest said to Hoagland. "When they discovered Uranus, the solar system doubled in size instantaneously"  ;D That was nicely done.

I also liked White's throw-away line questioning the desirability of having people on the spectrum being the ones to finesse artificial intelligence.  That's not likely to lead to a happy "singularity".

He was a good guest.

Not over long periods in interstellar space. Too many cosmic rays and such to degrade the chemistry.

What if the organisms were buried deep in the ice?

Much better chances, but not likely to be enough. Oumuamua, wherever it's from, has been traveling through interstellar space for at least tens of millions of years. On those time scales, organics as complicated as DNA just fall apart. There was actually a discovery of what's probably dinosaur soft tissue mummified in long bone fossils, and while you can see what appear to be proteins and collagen, the DNA itself is just too far gone. Frozen in space deep inside an asteroid it would last longer, but not likely to remain viable on geologic time scales.

Then again, there are some seriously tough fucking microbes on this planet that can dry out and survive absolutely massive amounts of radiation, such as D. radiodurans or T. gammatolerans. You can dose the shit out of the latter with gamma rays and it shrugs it off. Think 30,000 Gy as a lethal dose for them, whereas it's around 5 Gy for a human. So I suppose it could be possible for some microbe to be the equivalent of "the alien" and be almost impossible to kill in the environment of space if part of its evolution included a lot of exposure to space or very long term periods of being dried out, which seems to give resistance to radiation as a side effect for some earth microbes. So who knows, I'd never want to be in the position of predicting what life can and cannot do, especially microbes. It's more about likelihoods.

So the "Deep State" allowed that show to go ahead... there's a surprise.

Hoagland is a liar.

What if they could be encased in some material like this? I also think they should call in the "Art's Stone," like "Art's Parts," not name it after a prominent Native American porn star.

The obvious concerns would be for the crystalline arcologies and glass domes; when you live in them you don't cast stones, even if they are made from minerals not available in our solar system or containing alien sperm.

You guys are such dorks.  I think this was the point Albrecht was really trying to make   ;)

So, is the 3 hrs just going to be Mr. Ego reading Adams' biography?
