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.

Why, of course! Except for the other seven or eight planets transiting the sun that would excite interest.

And if you want to disguise the fact that earth has oxygen ... "Looks like you're going to need a bigger laser."

I suspect that we’re a day late and a dollar short on this.

Thanks GOD we finally have a solution for this pressing issue!

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

It works, if the aliens happen to be looking at Earth from directly in front of the laser. A fraction of a degree off dead center and it doesn't work.

So all you need is an infinite number of lasers along the entire surface of the earth pointing in every possible direction.

MSM: “Mr. Trump - if aliens were secretly impregnating American women to raise a super-race of alien-hybrid humans to conquer the world - would you then accept abortion as an option?”

HEADLINE: “TRUMP CONSIDERS ABORTION OPTIONS FOR WOMEN!”

Too bad the aliens figured that out eons ago. I believe the Romulans were the first. They are out there right now watching the primaries for amusement. Ron Paul said so.

>>theyre undocumented humans...<<

I think the term is “undocumented beings” but I wil check my PC dictionary (which is titled “Good Talk Dictionary”).

I’ll bet something or someone else already knows we are here...

at this point it is far too late to do anything about it.

The way I figure it, the closest aliens should be in the neighborhood of Alpha Proxima. Since that’s about five light years away, they’ve been getting our TV signals for over sixty years, and “wouldn’t go there on a bet.”

Another way to view them using Obama logic would be to call them New Earthlings as they replace our culture.
