Thank you, ER. I do get what you write, but alien just don’t quite cut it for me. At all, and for a different reason.

There is absolutely NO concrete evidence of extraterrestrial visitations to terra at all, ever since time began. None. As well, absolutely no evidence for other life existing, advanced or otherwise, anywhere in the entire Universe. These being facts, that would have to leave terrestrial, be it a human-engineered product or some as yet to be exposed natural phenomenon (spooky action close-up) to be the only plausible answers. Alien sightings have been reported ever since Aurora, Colorado (c. 1897), with no solid evidence left behind, ever (very clean alien invaders — Vulcans?).

Reactions of sighted craft are abrupt, very polaristic (often mirroring maneuvers of an observer’s craft), and include the phenomenon of vanishing from physical sight. It all looks very spooky, very quantum.

There is always the possibility of an alien theme for these visitations, but not very likely. The polarity of these objects seems to create a distance barrier. We get too close, and then it either takes off at incredible velocity or vanishes from sight. Does that mean our approach forces the closing of some interstellar/trans-temporal doorway? We don’t know. If this is an incredibly advanced technology, how are we able to sneak up on them so often with big, noisy jets?

Quantum entanglements with the properties of dark energy and dark matter?

Nature does strange things, often more bizarre than anything of which humanity is capable. We have no idea what any of this is, but I find it all self-demanding for research.

We will be able to do spectroscopy on the atmospheres of Earth-like planets around Sun-like stars- allowing us to look for the atmospheric markers of life – and perhaps even technologically advanced life…

These tools will lead to a revolution in astronomy, and looking at extra-solar planets will only be a small part of what will be made possible.

The universe- as we know it- will change dramatically in the coming decade.

Imagine what we will see with a 10 or 30 or even 100meter telescope that can operate ON THE GROUND at its diffraction limit (EVEN AT VISIBLE WAVELENGTHS!) for a TINY fraction of the cost of the JWST…

THAT is where we are heading, perhaps in this decade.

What’s most frustrating about the U.F.O.s story is that it obscures the fact that scientists like me and my colleagues are on the threshold of gathering data that may be relevant to the existence of intelligent extraterrestrial life. But this evidence involves subtle findings about phenomena far away in the galaxy — not sensational findings just a few miles away in our own atmosphere.

Powerful telescopes that will soon be operational may be capable of detecting city lights on the night side of planets that orbit distant stars or the telltale mark of reflected light from planet-wide solar-collecting arrays or the distinctive sign of industrial chemicals in a planet’s atmosphere. All of these “technosignatures,” should we find evidence of them, will be small effects. If we do detect such things, you better believe that my colleagues and I will go to extraordinary lengths to eliminate every possible source of error and every possible alternative explanation. This will take time and careful effort.

Being on a smaller scale (ie created by an aircraft nearby) I don’t see how the aircraft doing it would go un-noticed…

The U.S. Navy has patented technology to create mid-air images to fool infrared and other sensors. This builds on many years of laser-plasma research and offers a game-changing method of protecting aircraft from heat-seeking missiles. It may also provide a clue about the source of some recent UFO sightings by military aircraft.

But the real story isn’t disclosure, and it’s stranger than any UFO sighting. Behind the creamy pages of high-end magazines and the marble columns of the Capitol, the media elite and Congress are being played by a small, loosely connected group of people with bizarre ideas about science. It’s easy to dismiss UFOs as a fantasy or a fad, but the money, the connections, and the power wielded by a group of UFO believers—embedded in the defense industry and bent on supplanting material science with a pseudoscientific mysticism straight from the History Channel’s Ancient Aliens—poses a danger to America more real than a flying saucer.
