  • Earth zooms around the sun at 110,000 kph,

  • but what if it just...stopped?

  • Well, for one thing, you'd have only a month to live.

  • First off, if Earth stopped short,

  • you'd actually die immediately

  • because you'd fly off the planet

  • and hurtle into space,

  • just like you lurch forward in a car

  • when a driver slams on the brakes.

  • But if Earth slows down more gradually,

  • you'd instead suffer a slower (but still horrific) death.

  • That's because the planet is about to get

  • very, very hot.

  • You see, the sun's tremendous gravity

  • pulls the Earth right toward it.

  • Meanwhile, the planet is trying to whiz away

  • in this direction.

  • This tug of war keeps us in orbit.

  • But if the Earth slows down and stops,

  • the sun wins and yanks us toward our doom.

  • In fact, a model from the University of Colorado

  • shows us how long that terrible trip would take.

  • Just two months.

  • In the first week, you wouldn't notice

  • much of a change.

  • The average global temperature would climb

  • less than 1 degree Celsius

  • and hover around 16 degrees for another week.

  • But the closer we get, the stronger the sun's pull

  • and the faster we go.

  • This causes the temperature to rise exponentially.

  • By day 21, global temperatures will have jumped

  • to 35 degrees.

  • That's hotter than an average day in the Sahara.

  • And with desert heat comes desert droughts,

  • sparking wildfires and killing crops.

  • UV radiation from the sun is so strong,

  • we'd get severe sunburn after just 15 minutes outdoors.

  • At this point, our bodies also will have hit

  • the upper limit of their heat tolerance.

  • Any hotter, and heat stroke can set in,

  • leading to exhaustion, delirium, or even a coma.

  • And guess what? It gets hotter.

  • By day 35, world temperatures will reach 48 degrees.

  • That's as hot as an average summer day in Death Valley,

  • one of the hottest places on Earth.

  • Most mammals, birds, and insects die

  • as the proteins that make up their cells

  • start to cook.

  • Yes, even roaches can't withstand this apocalypse.

  • If we want to live,

  • we need some indoor air-conditioning, stat.

  • Except, the amount of energy you need

  • to run millions of AC units at once

  • would wipe out power grids around the world.

  • So, with no way to keep cool, humanity dies.

  • By day 41, the Earth has passed by Venus.

  • We're now the second planet from the sun,

  • and temperatures have climbed to 66 degrees.

  • But believe it or not,

  • some creatures still cling to life.

  • Like Thermus aquaticus, a bacteria that lives

  • in Yellowstone's hot geysers.

  • But less than a week later,

  • temperatures are hot enough to boil water

  • and kill even that bacteria.

  • By day 54, temperatures surpass 160 degrees,

  • and the last remnant of life on Earth flickers out.

  • Soon after, the barren planet crosses Mercury's orbit.

  • For its last week of existence,

  • Earth is the first planet from the sun.

  • Until day 65. The final day.

  • By now, the sun's extreme gravity

  • stretches the planet into an oval shape,

  • and magma begins to leak through the crust.

  • At about noon, Earth tears apart,

  • bleeding liquid rock as temperatures hit

  • 3,800 degrees.

  • Our planet is no more.
