WASHINGTON (AP) — Electrifying the world of physics, scientists said Thursday that they have finally detected gravitational waves, the ripples in the fabric of space-time that Einstein predicted a century ago.
Astronomers hailed the finding as an achievement of historic proportions, one that opens the door to a new way of observing the universe and the violent collisions that are constantly shaping it. For them, it's like adding sound to a silent movie because these waves are the soundtrack of the cosmos in action.
Republican governors who are running for president have made much of the fact that they have had executive experience as governors. They claim such experience prepares them to be president and those candidates without it, like Marco Rubio, thereby are not as qualified. The argument goes only so far, and that's not very far at all.
The principal responsibility of the President of the United States is to be our Commander-in-Chief, to keep us safe. None of the presidential candidates has that experience; not Trump, not Cruz, not Bush, not Kasich, not Christie and not Rubio.
