Loading ...The Hubble Deep Field
It’s been called the most important image ever taken…
In 2003, the Hubble Space Telescope stared, for a little over 11 days at a rather unremarkable section of sky. The results were humbling on a universal scale.
The Deep Field/Ultra Deep field images taken by the Hubble Space Telescope represent the farthest we’ve ever seen into the universe. Looking at these images, one cannot help but be humbled by what they mean. At a glance, they show us how tiny humanity is in comparison to the size of the universe.

The Fermi Paradox
Given the immense size of the known universe, we should expect to not be alone as far as life is concerned. In fact, probability says that we should be only one of a great many advanced civilizations. Concerning this, the Fermi Paradox says the following:
The size and age of the universe suggest that many technologically advanced extraterrestrial civilizations ought to exist. However, this hypothesis seems inconsistent with the lack of observational evidence to support it.
This either means that advanced civilizations are common and there is a reasonable explanation as to why we have not been in contact with them, or that the conditions necessary to support life as we understand it are so absolutely unique that they happened only once; that idea is fleshed out more completely in the Rare Earth Hypotheses.
