Imagine how things might be a trillion years from now. That’s about seventy times the current age of the universe (about 13.75 billion years), so I'd guess there will have been a few changes. No EU, no politics, no celebrities, no climate science, no Christmas shopping and no dog shit on the pavements. But I digress.
Of course our sun will be long gone and so will the Solar System. The sun may become a red giant and engulf the Earth with some genuine global warming - or it may not, we don’t know.
Our entire galaxy may collide with the Andromeda galaxy in three to five billion years time, so there is more than one possible fate lying in wait for our little Solar System.
What about us? Will we be remembered in a trillion years time? Well I don’t know about your ego, but mine says we won’t. So what will be left of us?
The obvious answer is nothing – but do we mean nothing at all? I’d say yes to that question. In a trillion years time there will not be the slightest trace of our existence. Not a single proton, neutron or electron, not a single quantum of radiation will tell the smallest hint of our story. Every last quantum of it will be gone.
The universe will change to such an extent that our onetime existence here on dear old Earth is no longer even a fragment of data. Data and laws - we are the data, not the laws. In the end, all data is deleted, so the time will come when we never existed.
