How To Navigate Using the Stars

Without clouds, about 6,000 stars are visible in the night sky, from anywhere on Earth. This number is lower in areas of heavy light pollution, but for the most of human history, this is what we had to look up to. In earlier times, there were many ideas as to what the stars were. The Greeks saw constellations, who were sentient, divine beings, awarded with the place among the stars, for some great deed done long ago. To the Paiute tribe, who lived in the Great Basin of North America,…

What If You’re Underwater During a Tsunami? | Unveiled

What Happens Underwater During a Tidal Wave? Earth’s oceans stretch out as far as the eye can see, blue and endless in every direction. But, as mysterious as those infinite horizons are, at 0.3 billion cubic miles in volume, there’s far more going on beneath the water’s surface.

Better act quickly; in a matter of minutes, you may be underwater. Here’s how to survive a tsunami, Tsunamis are triggered by intense underwater activity, usually an earthquake, or an underwater volcanic eruption. These events displace huge volumes of water, pushing it up from the ocean’s floor to its surface. But when gravity pulls it back down, all this built up energy is released…

So, for many species, we’re just terrible news, but there are exceptions. Some species even seem to thrive in the biggest most densely populated…

How Long Can Humans Outrun Extinction?

Modern humans evolved a couple hundred thousandyears ago. And between ice ages, volcanoes, climate change,earthquakes, droughts, floods,and Reddit being down sometimes, we’ve seen some stuff. But on cosmic timescales, two or three hundredthousand years is just a drop in the bucket. The longer we’re around, the more likelywe are to witness something truly Earth-shattering,whether metaphorically or literally. And someday, if we’re still here,we’ll have to face things like Earth melting as it’s engulfed by the Sun. Or the Sun going out. Or galaxies colliding. One way or the other, we’re…
