VIRGO:
Planetary (Transit) Cloaking is a bad idea. – Concept Parade

Recently several astronomers, professor David Kipping and graduate student Alex Teachey at Columbia University submitted a paper to the Royal Society of Astronomy detailing
how we could camouflage the earths presence via use of a laser array. The goal would be hiding the earth’s transit in front of the sun by making up the light that the earth
blocks from the perspective of another galaxy. More advance use of this method could hide more data such as the elements in our atmosphere. The rational behind hiding is
that if there were intelligent civilizations other than our own, they may be searching for planets and new civilizations in the same way that we do. It is possible that some
of these proposed alien civilizations are malevolent. If these civilizations have accomplished interstellar or perhaps even intergalactic travel capabilities they could travel
here and act out their malevolent intent.
It only takes a moment to realize what an exceptionally bad idea this actually is. Consider the goal here. The goal is to NOT attract the attention of an advanced malevolent
alien civilization. The method proposed to do this is to abruptly disrupt a natural “signal” that has been broadcasting for billions of years. In this case the signal is
the dip in light due to the earth’s transit between the alien civilization and our sun. Frankly, I can think of few things that an advanced alien civilization would find more
interesting that the abrupt disappearance of a previously stable planet that may have been noticed, categorized and mapped by said civilization thousands or even millions
of years ago.
The only good way to implement this camouflage would be to simulate a natural disruption to the earths transit system such as a slow orbital shift. In nature such a shift
would take (insert astronomical amount of time here). Our simulation would need to replicate the process over a very long time. It seems unlikely that such a timeline would
be achievable by humanity as we currently are. Any attempt to mask the atmosphere of Earth or the elements within would need to also mimic a natural process.
