Above us only sky...

The glory of the 'heavens' above us are real, their starry splendour is visible to those who look up; but the glory of 'Heaven' is a sad delusion of human minds.
This is the personal blog site of an atheist astronomer.

Wise words

"If religion wants to understand the truth, it must do so by embracing science, not by dismissing it. It must accept those who do not share their unverifiable beliefs, not vilify them. It must debate the findings of science, not dismiss them out of prejudice."
Roger Powell
