Proust and the paradox?

Stumbled on this NPR article—Where is Now? The Paradox of the Present, by Adam Frank —thanks to facebook today and thought it was particularly worth sharing. Harks back to these pages/this post from a few days ago.

An excerpt:

"Signal travel time constitutes a delay and all those overlapping delays constitute an essential separation. The inner world of your experience is, in a temporal sense, cut off from the outer world you inhabit.

Let's take a few examples. Light travels faster than any other entity in the physical universe, propagating with the tremendous velocity of c = 300,000,000 m/s. From high school physics you know that the time it takes a light signal moving at c to cross some distance D is simply t = D/c.

When you look at the mountain peak 30 kilometers away you see it not as it exists now but as it existed a 1/10,000 of a second ago. The light fixture three meters above your head is seen not as it exists now but as it was a hundred millionth of a second ago. Gazing into your partner's eyes, you see her (or him) not for who they are but for who they were 10^-10 of a second in the past. Yes, these numbers are small. Their implication, however, is vast.

We live trapped in our own now."
