Well, you'd think that it would be pretty darned difficult to cover up a giant spaceball crashing into the earth and wiping out a city somewhere, causing a tidal wave, or tossing up a sun blotting dust cloud even if it hits an unpopulated area.

I doubt that anything that I can see burning up in the atmosphere by my own observation of the night sky is much of a 'secret' anyways.

And when that giant global killer does come, will it really matter if we know it's on it's way? What can we do about it? buld our own spacecraft in our back yards in a hurry so we can escape to- where?

The mass panic, people running around on killing sprees or what ever they want to do on their last day would ruin any chance of being able to throw a good "last day" party, so it would be best we didn't know we are all going to die in 24 hrs.

Ya, but imagine spending you last day at work, what a bummer ... I’d rather know and go fishing with the kids ...
