Aliens probably long dead, say scientists

[littlebabyjesus]

I think the point is that the metre and/or the second (can't remember which) is defined so that light speed is precisely that number.

Ah I see.

 

[DotCommunist]

now we've got a way of long distance signalling using gravity waves it can surely be aliengeddon within, say, 3.34 years

I could imagine aliens looking at earth from afar and thinking "can't be any life there, it's wracked by massive tidal forces from its weird moon creating unusually unstable conditions - life needs conditions like those found on our planet, with its eccentric orbit allowing long periods of stable conditions with the occasional heat of perihelion to facilitate the necessary chemical reactions"

Life on that small blue dot? Nah, way too much deadly oxygen, and all that dihydrogen monoxide. Temps regularly soaring well above 300 degrees kelvin... if theres life there, its extremophile life, that's for sure.

It even has a magnetic field which must filter out so much radiation from its star that the rate of change and adaption must be glacial. Probably won't get past single-celled plankton.

A flashlight works over the same distance, and is a lot cheaper.

Yes, the second is defined as 9192631770 cycles of the radiation from a particular state transition of a caesium 133 atom, and the metre is defined as the distance travelled by light in vacuum in 1/299792458 seconds.

Rather pleasingly, the speed of light in a vacuum is very nearly 1 foot per nanosecond.

Mixing imperial and SI? How very gauche! I prefer to measure c in furlongs per millifortnight myself (~1802617758 in case anyone couldn't remember off-hand).

Talk like this isn't helpful when I'm trying to get funding for my orbiting-black-hole-machine-gun

all that dihydrogen monoxide

You joke about these things... but DHMO is lethal stuff. I got some on my hand once but thankfully I was able to wash it off before it did too much damage.

Here's your answer to how 'aliens' might be able to make interstellar trips:

Elon Musk’s Billion-Dollar Crusade to Stop the A.I. Apocalypse

It might also explain why there's been no attempt at contact: the living beings that created their AI are now dead, and the AI which inhabits the space ships coming to earth, has no interest in contacting the meatspace lifeforms here. They're here for some other reason.

The UFO disclosure myth

 

[EastEnder]

The most truth you'll ever hear about the ET / UFO situation since the end of WW2 -
Disclosure is unlikely to happen in our lifetime.

Unacknowledged (2017) - IMDb

"Unacknowledged" focuses on the historic files of the Disclosure Project and how UFO secrecy has been ruthlessly enforced-and why. The best evidence for extraterrestrial contact, dating back decades, is presented with direct top-secret witness testimony, documents and UFO footage, 80% of which has never been revealed anywhere else. The behind-the-scenes research and high-level meetings convened by Dr. Steven Greer will expose the degree of illegal, covert operations at the core of UFO secrecy. From briefings with the CIA Director, top Pentagon Generals and Admirals, to the briefing of President Obama via senior advisor John Podesta, chairman of the Hillary Clinton Campaign, we take the viewer behind the veil of secrecy and into the corridors of real power where the UFO secrets reside. The viewer will learn that a silent coup d'état has occurred dating back to the 1950s and that the Congress, the President and other world leaders have been sidelined by criminal elements within the military-industrial-financial complex.

Sounds very measured, balanced & objective.

Well it's first hand testimony by people with various security clearances, air traffic operators, military and civilian, and numerous government officials who are happily testifying to documents and evidence as witnessed by themselves. These individuals are all verifiable if you really wanted to dig. It's not as if any of these folk are getting a huge paycheck to spout bollox.

The quoted description does not give me much confidence that the film will present balanced arguments, rational counterpoints and objective analysis. TBH, it sounds a bit conspiraloony.

There are various trailers of it on YouTube to check out if you wish. Personally I'm more interested in the possibility of a cover-up of alternative propulsion technology behind radar verifiable incidents mentioned in films like this. The ET solution is always a good cloak for top secret craft the military have. But in this case it would mean withholding technology that would sort climate change overnight. Of course if the ET cause were to be true then that's an even more humongous cover-up.

Did ET suddenly become interested in Earth only when the Cold War started?

Wouldn't know - there's many that reckon they've been around for 1000s of years. But we've only had radar and the ability to track and record more than we can see since WW2.

Ah, I see. These are radio signals then or somesuchlike. And all those folk at SETI and other institutions have been hoodwinked.

I tend to find that most people don't need any level of remuneration to spout bollox.

No need for the internal combustion engine. Planes, ships, cars, lorries - redundant overnight, (of course it would take time to replace those - but you get the meaning).

Like I said ET could be the cover for top secret aircraft. No doubt a lot of sightings of early stealth fighters were happily brushed off with ET nuttjob explanations. Therefore there are no ET signals to hear.

I'm confused now. Your original quoted text boasts of 'The best evidence for extraterrestrial contact'.

Well the thread is about Aliens, and so the film I linked to is relevant to the thread title, but that doesn't mean it's my main interest. If folk on here are more interested in ET then watch the film at face value.

I fear it may be better to watch that particular film at arse value.

I saw a documentary once where they terraformed mars in a matter of minutes. I can't totally recall what its name was though

Yes, I think I saw that. It really concentrated on the plight of the immigrant population, as I recall. Especially the ones with three tits.

Certifiable more like.

In 1998, Greer described how the government was having special forces attack and kill aliens in Colorado using Sarin gas. Apparently, Greer was telepathically contacted by the aliens as they were attacked and Greer felt a need to alert the world of this debacle.

I know, but he's not the one giving the testimonies.....it's not his evidence.

It's his organisation.
