«Yes. Human feet are still adapting to their task of keeping you erect. You propose, then, that our intelligence has grown sufficiently to ensure our survival without depending on your hit-or-miss method of learning everything you can for the sheer pleasure of learning.»

«Not quite. Our method is better. If you hadn't sent me to the Core for publicity, you'd never have known about this.»

«You say the galaxy is exploding?»

«Rather, it finished exploding some nine thousand years ago. I'm wearing grade twenty sunglasses, and it's still too bright. A third of the Core is gone already. The patch is spreading at nearly the speed of light. I don't see that anything can stop it until it hits the gas clouds beyond the Core.»

There was no comment. I went on. «A lot of the inside of the patch has gone out, but all of the surface is new novas. And remember, the light I'm seeing is nine thousand years old. Now, I'm going to read you a few instruments. Radiation, two hundred and ten. Cabin temperature normal, but you can hear the whine of the temperature control. The mass indicator shows nothing but a blur ahead. I'm turning back.»

«Radiation two hundred and ten? How far are you from the edge of the Core?»

«About four thousand light-years, I think. I can see plumes of incandescent gas starting to form in the near side of the patch, moving toward galactic north and south. It reminds me of something. Aren't there pictures of exploding galaxies in the Institute?»

«Many. Yes, it has happened before. Beowulf Shaeffer, this is bad news. When the radiation from the Core reaches our worlds, it will sterilize them. We puppeteers will soon need considerable amounts of money. Shall I release you from your contract, paying you nothing?»
