I don't understand the clock one.

The shark fact is impressive though. I like to tell folks that the galaxy is so big that the solar system hasn't even made 1/4 of an orbit since the non-avian dinosaurs went extinct. Might add some perspective.

Nitpick: there are many species of shark so maybe you meant taxonomic genus or family.

I don't understand the clock one.

Part of the western Florida panhandle (WFP) is on Central time. Part of southeastern Oregon (SEO) is on Mountain time. That puts them one hour apart.

In the fall, when we go back into Standard Time, when the clock hits 2am, you flip the clock back to 1am.

So, during a normal night, WFP would be at 2am and SEO would be 1am. But on the night the time changes, WFP hits 2am and immediately flips their clocks back to 1am - which means that, for one hour a year (until SEO hits 2am and flips their clocks back), part of Florida and part of Oregon's clocks are showing the exact same time.

I kinda struggled over how to word this - they're not in the same time zone, but for this one hour they might as well be.

Ah okay, I get it now. You explained that perfectly, thanks!

Wouldn’t they be aligned twice per year?

[–] brygphilomena@lemmy.dbzer0.com 13 points 4 weeks ago

I think when it flips the other way they get an extra hour further apart.

It's not as impressive because Florida is further east, but the four Michigan counties that border Wisconsin experience the same thing.

Well the specifics are the lineage which includes sharks, we found stuff that might be sharks but hard to prove are definitely sharks that's 450 million years old (fossil sharklike scales)

And, this is copypaste from Snopes:

The earliest known fossil evidence of sharks (or their ancestors) are "shark-like scales" that date back to 450 million years ago, according to the National History Museum in London. However, whether these scales adorned "true sharks" or "shark-like animals" is an issue debated by the scientific community.

Nonetheless, scientists largely agree that, according to DNA evidence, living sharks, rays, and deep-sea fish called chimeras likely began evolving around 420 million years ago.
