There's a Known Space story like that by Larry Niven, "Madness Has Its Place."

Interesting! A giant Zardoz head. And the ribbing on the chamber walls are distinctly Alien, like the egg chamber beneath the derelict. Are the "ampules" somewhat reminiscent of Alien eggs?

If they were ever to use the character, I think Cumberbatch would make a fantastic Master to Matt Smith's Doctor.

Yeah, the use of the present tense can be confusing. Often in astronomy people talk about events they're observing as happening "now" regardless of how far away they are - and that's perfectly fine, really. What they're doing is talking in light cone coordinates.

I just love these tentacled guys.

Whoa!

I for one welcome our cephalopod overlords!

Anne, thank you for the worlds you let me visit. I've pulled Dragonflight and Restoree from my bookshelf, and I'll be traveling there again.

Uuuuuu-lllllaaaaaa!

Although GEO600 might not have really detected holographic noise, the graininess of the hologram could actually be testable.

"If they're travelling faster than light, doesn't that mean that they have to be travelling backward in time, as well?"

There are a few things on here that seem a tad unlikely.

I am a little confused about some of the figures in the original paper. For instance, RCP8.5 (albeit the most extreme track) appears to include 18.4x10^3 gigatons of fossil CO2, which to the best of my knowledge exceeds total forecast fossil carbon reserves by a factor of about 4. The estimate is something like 4000…

Of course the existence of tropical forests in the arctic by 2300 is suggested nowhere in the original publications. The image emerged somewhere in the reporting chain.

The model discussed above, RCP8.5, has a net excess forcing of 12W/m^2 from concentrations of CO2, CH4, NO2, and various.

I have a fragmentary memory of Charlie Stross saying Palimpsest could be the first part of a novel. Or possibly that his editor saw it like that? I'm not sure if that was merely idle observation, or wishful thinking on my part!

I watched that again recently. Great movie.

"Abe and Aaron have a working time machine, which goes back in time six hours."

"I've always wondered why more writers don't have stories where temporal warriors just build a very tough vehicle and go all the way back to a second or two after the Big Bang and just cause a few particles to zig instead of zag."

Interesting.
