Breaking Temporal Continuity

It seems like a lot of the stories that I've read or seen that involve time travel (setting aside, just for the moment of this discussion, that it seems to be extremely unlikely that time travel is possible at all) involve attempting to restore or regenerate a timeline that has otherwise been lost. I have seen/read exceptions; The End of Eternity by Asimov (and I really need to refind this book) has as a central point of its plot that >!developing time travel as a technology enabled humanity to stabilize its timeline to such an extent that it deterred interstellar travel and eventually led to human extinction in the far future.!<Is there much science fiction that's about fracturing the timeline instead, of even treating that as a positive as compared to a continuity that is so terrible that even disrupting it is an improvement? And if not, why not? Does it have a lot to do with the complexity of writing something like that?

Brugmansia Flower Up Close

My Brugmansia plant flowers in the back yard. It had some trouble earlier this year but I'm glad it recovered and I got it to flower again this year because I wasn't sure if it was going to. I've never seen it fruit (unlike the Daturas) and I'm curious if anyone's gotten it to do so? Perhaps its temperature dependent and needs a warmer climate?

[Request] Boiling an egg in a Death Valley car

Looking at the NWS website at the weather forecast for Death Valley [offsite] Friday's low temperature is scheduled to be 86 degrees and the high temperature is 114 degrees Fahrenheit.

https://forecast.weather.gov/MapClick.php?lon=-117.306&lat=36.937

If you put an egg into tap water into a stainless steel hemicylindrical cooking pot 6" in diameter and 3.5" deep, placed this pot on the dashboard of a standard sized SUV painted black, and left the windows rolled up for the entire day assuming also [offsite] that sunrise is 5:58 AM and 7:47 PM at nearby Furnace Creek, would the water temperature ever get hot enough that you could boil the egg?

I hope I asked this the right way.

Euphorbia resinifera

Name: Resin spurge

Scientific Name: Euphorbia resinifera

Why is it poisonous: Euphorbia resinifera contains, among other compounds, resiniferatoxin. While it is chemically classified in the same group (daphnane diterpenes) as other toxins frequently found in the Euphorbiaceae such as phorbol (from Croton) or the toxins from manchineel, resiniferatoxin has a very different mechanism of action. It binds to the same ion channel as capsaicin except that it does so to a much stronger degree, inducing extreme pain initially and then eliminating pain as the nerve cells that it binds to die afterwards.

From wikipedia: https://en.wikipedia.org/wiki/Resiniferatoxin

Do hybrids count?

Do hybrids count as poisonous if you can't find specific articles documenting chemical composition/journals/case studies of poisonings but they come from genera that can reasonably assumed to be poisonous and don't seem to have edible species/varieties in them? I'm thinking of Pieris, Cephalotaxus, so on?

What are you buying or getting this month for your collection if you've planned it out? I got Noir Magnetique by Die Form (unfortunately digital only) and Nocturnal Birding by Author and Punisher but the CD hasn't arrived yet.
