Ignorance is the downfall of humanity, Expanding your mind with Knowledge and Education is important.
But in the colossal dimensions of the cosmos our stellar system is only a tiny part of an incomparably larger stellar system-of a cluster of Milky Ways, one might say,
containing some twenty galaxies within a radius of 1 1/2 million light years (1 light year = the distance travelled by light in a year, i.e. 186,000 x 60 x 24 x 365 miles).
The astronomer Harlow Shapley estimates that there are some 10 <20> stars within
the range of our telescopes.
If we continue to speculate on the basis of this estimate and suspect the
necessary conditions for life on only one star in a thousand, this calculation still gives a figure of 10 <14>.Shapley asks: how many stars in this truly 'astronomical' figure have an atmosphere suitable for life? One in a thousand?
That would still leave the incredible figure of 10 <11> stars with the
prerequisites for life.. Even if we assume that only eve
