I heard that it would take, using present technology, about one and a half million years to travel 40 light years.
To reach the nearest star, a mere 4 light years away from the sun, would take about fifty to eighty thousand years...just one way.
I don't know about you, but it makes me feel so very small, an almost no-thing inhabiting a speck of dust
located within a galaxy containing about 100-200 billion stars which is scattered somewhere
among 200 billion or more other galaxies, each containing about one hundred billion stars. So, how many stars are there?
There are more stars in the universe than all the grains of sand on all the seashores and deserts of Earth.
A human being could not live long enough to count every star if that's what he was doing all the time.
