The Global Genetic Coronal Phosphorescent Thermohaline Economic Asteroid-Earthquake Singularity War That Will Doom Us All

“The Last Day of Pompeii” by Karl Briullov.

In the real world, disasters aren’t just a matter of scale – they’re a question of preparedness and of a society’s capacity to handle the fallout. Vaccines, rapid-response teams and early-warning systems can move the needle from calamity toward recovery, while poverty, corruption and ignorance slide it toward catastrophe. So, cue announcer: “In a world … where real disasters aren’t single events that arise from simple problems that are solvable in 93 minutes  …”

10 Possible Future Disasters

Yellowstone and the Terrible, Horrible, No Good, Very Bad Day

The eruption of Krakatau in 1883 is synonymous with cataclysm, and with good reason. Its eruptive power equated to several thousand atom bombs, and it killed around 36,000 people. But compared to the supervolcanoes that nearly wiped out humanity, or that may yet spell global catastrophe, it was a wet squib.

Of Mammoths Wild and Woolly

We love dinosaurs, but we never shared the planet with them. Such was not the case with woolly mammoths, which we once hunted, chowed down on, and used for tools and building materials. You don’t see T-Rexes on cave walls, but some of the earliest sculpture and art by human hands depicts these elephantine throw rugs.

Today, their well-preserved remains contain muscle, blood, teeth, bone, tusk and even brain. We’ve recovered and sequenced mammoth DNA, something we’ll never be able to do with dinosaurs. But if all you know about these majestic creatures comes from old Flintstones episodes, then join me as I explore …

Cosmos is back, and Neil deGrasse Tyson is tooling around the universe in Carl Sagan’s Ship of the Imagination. But suppose someone handed you the proverbial keys? Where in space and/or time would you go?

If you don’t have a ready answer, never fear. I’ve put together an itinerary that can’t fail, whether your tastes run to science or sightseeing. Sure, we might have to break a few physical laws and grow a few extra senses along the way but, hey, it’s not called the Ship of Literal Reality, is it? So hang your fuzzy planets from the rearview and strap in for a star-spanning tour, a jaunt from the local neighborhood to the unreachably distant (and disproportionately dangerous) corners of the universe, en route to…

Like a Bridge Under Troubled Waters

Between the years of 1825 and 1843 , through floods and financial failures, Marc Isambard Brunel and his son dug a tunnel under London’s Thames River. Our ambitions have grown since then, but the technology we use still bears a striking resemblance to Brunel’s shipworm-inspired device.

In this article, I look at some of the worlds most breathtaking underwater tunnels and delve into how they were constructed.

How do you build an underwater tunnel?
