On this logarithmic scale we can see our own lifespan and size in relation to the universe.
The universe has expanded to 10 to the power of 27 metres diameter in 14 bn years
You expanded from 0 to 2 metres in about 20 years.
Our sun began life as a cloud of gas 5 bn years ago and will end as a red giant in about 5 bn years’ time.
Your life will end in less than half a million hours.
