Keep calm and carry on

Some astronomically catastrophic events are predicted by astrophysicists, but they do serve to highlight how lucky we are to be alive.

In one billion years from today,
With a 10% brighter Sun shining,
All our vaporous water will have gone;
So for life1, there’ll be no silver lining.

Don’t worry, don’t fret, don’t panic!
Keep calm and just carry on.
The present is yours to experience –
Enjoy it before it is gone.

A runaway greenhouse effect
Will inevitably come into play
As the Sun fattens up and gets brighter
And boils all Earth’s water away2.

Don’t worry, don’t fret, don’t panic!
Keep calm and just carry on.
The present is yours to experience –
Enjoy it before it is gone.

Andromeda (M31),
Which is now just a faint, fuzzy blur,
Is due for a Milky Way crash3,
And that’ll create quite a stir.

Don’t worry, don’t fret, don’t panic!
Keep calm and just carry on.
The present is yours to experience –
Enjoy it before it is gone.

The time will arrive, one fine day4,
When the Sun will swallow the Earth
As it swells to become a red giant
And shine out for all it’s worth.

Don’t worry, don’t fret, don’t panic!
Keep calm and just carry on.
The present is yours to experience –
Enjoy it before it is gone.
