The Most Horrifying Ways The Earth Could Die According The Most Popular Theories

Earth sustains life only because our planet teeters on a delicate and truly improbable balance.

Our atmosphere, proximity to the sun, and countless other beautiful coincidences not only permit life to evolve but also thrive.

And yet, here we are, sitting at desks and in coffee shops and walking down the street like our very existence isn’t some kind of extraordinary miracle. space science and universe of science of planet science space

But all good things must come to an end. space science and universe of science of planet science space

One day Earth will be inhospitable to anything resembling life as we know it. space science and universe of science of planet science space

The life on this planet likely won’t until billions of years from now. But, depending on the vicissitudes of astrophysics, it could also happen tomorrow or anytime in between. space science and universe of science of planet science space

Here are the many ways scientists believe the Earth could die. space science and universe of science of planet science space

1) The Earth’s molten core might cool.

The field is generated by Earth’s rotation, which swirls a thick shell of liquid iron and nickel (the outer core) around a solid ball of metal (the inner core), creating a giant electric dynamo. space science and universe of science of planet science space

If the core cools, though, we’d lose our magnetosphere — and also our protection from solar winds, which would slowly blast our atmosphere into space. space science and universe of science of planet science space

Mars — once rich with water and a thick atmosphere — suffered this same fate billions of years ago, leading to the seemingly lifeless world we know today. space science and universe of science of planet science space
