Lasers could 'cloak Earth from aliens'
BBC News ^ | 3/31/3016

We should shine lasers into space if we want to hide our presence from aliens, two US-based astronomers suggest.

The beams could compensate for the dip in light the Earth creates when it passes in front of the Sun, as viewed from far-off worlds, they contend.

But an alternative might be to use a laser simply to disguise the interesting aspects about Earth - features in its atmosphere that betray the fact that life exists here. These are a suite of gases that include oxygen, ozone and methane.

I can FINALLY sleep at night knowing the impending space invasion will be stymied with our cloaking device!

When the global warming scam collapses, this could be the next Democrat cause. It would fit right in with the Hollywood elite and Scientology.

I think we should advertise. Maybe somebody out there would be interested in buying the extra forty nine feet of water we'll be wading in when the Antarctic ice sheet melts. We could use the proceeds for reparations!

When they come just shoot it up toward their eyes. FAA says it is bad.

I’m a laser guy for over 30 years. This fantasy. We’ll have warp drive before that happens.

We’ve already broadcast Obama’s speeches to the entire universe. That should keep all ET’s far, far away.

Giorgio is fun to watch but he’s a bit of a nut. Love that artwork.

I’m not saying it was painted by aliens, but it was aliens!

Humans are the only threat to earth and it has nothing to do with population control or global warming.

“There’s no point in acting surprised about it. All the planning charts and demolition orders have been on display at your local planning department in Alpha Centauri for 50 of your Earth years, so you’ve had plenty of time to lodge any formal complaint and it’s far too late to start making a fuss about it now. … What do you mean you’ve never been to Alpha Centauri? Oh, for heaven’s sake, mankind, it’s only four light years away, you know. I’m sorry, but if you can’t be bothered to take an interest in local affairs, that’s your own lookout.”

“Energize the demolition beams.”

The assumption of this article is that alien technology has to be as sucky as ours. 50 years ago we could not find extraterrestrial planets and even today we have planets in her own solar system we can’t find. Who knows what sensor technology we will have to view planets in the future, let alone the aliens might have.

If aliens were smart enough to get here, they probably have technology that would make this concept a joke to them.

I can imagine all the collisions form space alien freighters that did not see the earth and crash.

It works on the same principle as using neon lights to cloak cities from detection. /sarc
