Meant to share this last week, since it tied into my post about the state of our civilization, and the difficulty of keeping the broad sweeps of history in sight, but it fell between the cracks until now.

Lava, not water, formed canyons on Mars
Every so often we get a reminder that all scientific conclusions are provisional. The canyon-like scars which line Mars' crust are seen by many as evidence for liquid water.

The Big Bang’s Identity Crisis – The Nature of Reality
Think of the Big Bang, and you probably imagine a moment in time when matter, energy and space itself all burst into existence at once. Yet many astrophysicists now believe that the “Big Bang” was actually two distinct events: first the inaugural instant of space and time, and second the generation of most of the … Continue reading The Big Bang’s Identity Crisis – The Nature of Reality
