What will happen in 100 trillion years?

The galaxy will erode, with all the stars escaping into intergalactic space. We can look out into the Milky Way and see stars forming all around us. And so, in about 100 trillion years from now, every star in the Universe, large and small, will be a black dwarf.

In theory the Earth could do that to the Moon. If the Moon, for some reason, were to get much, much closer to the Earth — to within ten thousand miles — the Earth would start tearing chunks off its satellite. Fortunately the Moon is over two hundred thousand miles away, so such an event is pretty unlikely for now.

How long will humans last?

Humanity has a 95% probability of being extinct in 7,800,000 years, according to J. Richard Gott’s formulation of the controversial Doomsday argument, which argues that we have probably already lived through half the duration of human history.

What happens after humans go extinct?

Lacking human oversight, glitches in oil refineries and nuclear plants would go unchecked, likely resulting in massive fires, nuclear explosions and devastating nuclear fallout. “There’s going to be a gush of radiation if suddenly we disappear.

How long would buildings last without humans?

Which country went to Mars first?

1, 1962: Mars 1 (USSR) launched for an intended Mars flyby. The spacecraft made it to Earth orbit and beyond.
