Either Harrison Ford is in on the trick or David Blaine is God. Ninety seconds. You do not want to miss this.

Thanks to Tom Stolze for the link to this brief look into the outer reaches of space. It is one of those things I can’t begin to comprehend. To say that Earth is a speck of dust in the greater scheme of things is all but infinitely to overstate our physical presence — and makes our tiny space ship, and the nanosecond of geological time it has hosted us, all the more miraculous. What a responsibility to our forebears and offspring not to muck it up. Please vote!
And have a great weekend.
