Communion Of Dreams


“Should we be worried?” “Yes.”

That’s an exchange in today’s Sixty Symbols video, on the subject of asteroids:  Asteroids

But the point is made clearer as the scientist explains that the threat is unlikely – yet, if we had a major impact, the results would be catastrophic.

However, the bulk of the relatively short (6:36) vid is just talking about the asteroid belt, and how it is now thought to be a planetary body which failed to form, due to the gravitational effects of the other planets. One good item was discussion of how even though this is the case, the vastness of space is such that the chances of encountering an asteroid while traversing the belt is very remote.

It would have been nice if they talked about project WISE, which was used to detect some 25,000 new asteroids recently. But I suppose it was important that they talked about the 1970s video game “Asteroids”, instead.
