Sorry I just had to do this.

We don't have to worry, I just found this on Foxnews.com and I guess what it is basically saying is that if the light at the end of the tunnel is ever turned off, it will be a very long time before it really goes away.

The particles that make up light, photons, may live for at least 1 quintillion (1 billion multiplied by 1 billion) years, new research suggests.

This should put an end to all speculation on this subject.
