Re: 1747: "Spider Paleontology"

I wonder which type of dinosaurs might plausibly have spun webs? I read a strand of spider web is stronger than the equivalent thickness of steel. So I wonder how thick dinosaur web strands would be. As for their need to--there were a lot of dinosaurs much smaller than the T-rex and other predators....

Re: Fission Stars

Thanks, everybody.

Yes, I meant a star made of several elements, not just uranium. I didn't know how doable it would be.

Pu-244 has a half-life of 80 million years. And a really massive fusion star could last that long. It would be interesting to try a plutonium star.
