The Keck telescope, which is the largest in the world, had opened just before I began my faculty position at UCLA.

Fortunately, most things around the supermassive black hole are just going to go around it. They're going to orbit it. They don't actually get sucked in.

Ground-based telescopes are much larger than Hubble. Keck is four times larger than Hubble in diameter, which means that you can see four times the detail than you can see with Hubble, if you can figure out how to use these techniques.

The key to proving that there's a black hole is showing that there's a tremendous amount of mass in a very small volume. And you can do that with the motions of stars.

Even before I joined journalism, I knew that this is what I wanted to do. Tintin was an early inspiration.

'Time' is an internationalist publication catering to internationalist readers who are not only interested in their own backyard.

On the 11th anniversary of 9/11, it is some consolation that the man most responsible for that terrible morning will not be smiling smugly to himself as satellite TV brings to the leafy boulevards of Abbottabad the somber images of New Yorkers commemorating those who perished in the Twin Towers.

There's much talk about how there can't be democracy in a region that has problems of illiteracy and poverty. But I bring a different idea to the table when I say, 'Guys, I come from India. I'm more optimistic coming from where I'm coming.'

To conflict journalists, a tiny, tight-knit tribe, tragedy is practically an occupational requirement: our work requires us to seek it out, measure it, contextualize it, and chronicle it.
