If it were possible, wouldn't 15 billion years be enough time to get us there? I mean after all, look at what we have accomplished in 100 years, or is there a pink technology elephant in the room?

It's still all very speculative, but if they are there, then the reasonable assumption is the we are a farm, not a colony. If they were here to take over, then they would have already... or perhaps they already have?

How would we know? How can the ant know who holds the magnifying glass?

We're stupid and arrogant to think otherwise.


Oh the aliens have crash landed over and over again allowing our governments to glean their technology while holding their corpses in cold storage in some secret facility? really? Are they that inept? If they are then we have more problems, not less.

Just to continue with pure speculation......

SUPPOSE there was alien life visiting Earth

How would you break it to the population?

Just dump it on them in a news conference.
“My fellow Americans we are being visited by aliens from who knows where for unknown reasons in space ships that make us look dumb.”

OR would you kinda let little bits leak out, warm up the audience with the POSSIBILITY for a few years, make it a little more real over a generation, so that it becomes a PROBABILITY, and is accepted by the public before the BIG ANNOUNCEMENT.

But, as MD said, how would you know?

MAYBE “THEY” are really in control and don’t want to be known so they don’t get baked for the inevitable herd culling. Why rush in when we will do it for them?

There is a SciFi story there somewhere.

I personally liked the recent version of "The Day the Earth stood Still"
In particular these exchanges :
Regina Jackson: What is your purpose in coming here?
Klaatu: There is a gathering of world leaders not far from here. I will explain my purpose to them.
Regina Jackson: I am afraid that is not possible. Perhaps you should explain yourself to me instead.
Klaatu: Do you speak for the entire human race?
Regina Jackson: I speak for the President of the United States. Now please, tell me why have you come to our planet.
Klaatu: Your planet?
Regina Jackson: Yes. This is our planet.
Klaatu: No, it is NOT.
---------------------------------------------
Helen Benson: I need to know what is happening.
Klaatu: This planet is dying. The human race is killing it.
Helen Benson: So you have come here to help us.
Klaatu: No, I didn't.
Helen Benson: You said you came to save us.
Klaatu: I said I came to save the Earth.
Helen Benson: You came to save the Earth from us.
Klaatu: We can't risk the survival of this planet for the sake of one species.
Helen Benson: What are you saying?
Klaatu: If the Earth dies, you die. If you die, the Earth survives. There are only a handful of planets in the cosmos that are capable of supporting complex life.
Helen Benson: You can't do this.
Klaatu: This one can't be allowed to perish.
Helen Benson: We can change. We can still turn things around.
Klaatu:: We have watched. We have waited and hoped that you would change.
Helen Benson: Please.
Klaatu: It has reached the tipping point. We have to act.
Helen Benson: Please.
Klaatu: We will undo the damage you have done and give the Earth a chance to begin again.
Helen Benson: Don't do this. Please, we can change. We can change.
Klaatu: The decision is made. The process has begun.
------------------------------------------
Regina Jackson: History has lessons to teach us about first encounters between civilizations. As a rule the less advanced civilization is either exterminated or enslaved. I'm thinking of Pizarro and the Incans, Columbus and the Native Americans, and the list goes on. Unfortunately in this case, the less advanced civilization is us.
Michael Granier: This is the representative of an extra-terrestrial civilization. This is the most important discovery in the history of Mankind!
Regina Jackson: It may well be the last discovery in the history of Mankind.
Professor Barnhardt: There must be alternatives. You must have some technology that could solve our problem.
Klaatu: Your problem is not technology. The problem is you. You lack the will to change.
Professor Barnhardt: Then help us change.
Klaatu: I can not change your nature. You treat the world as you treat each other.
Professor Barnhardt: But every civilization reaches a crisis point eventually.
Klaatu: Most of them don't make it.
Professor Barnhardt: Yours did. How?
Klaatu: Our Sun was dying. We had to evolve in order to survive.
Professor Barnhardt: So it was only when your world was threatened with destruction that you became what you are now.
Klaatu: Yes.
Professor Barnhardt: Well that is where we are. You say we are on the brink of destruction and you are right. But it is only on the brink that people find the will to change. Only at the precipice do we evolve. This is our moment. Don't take it from us, we are close to an answer.

NASA Has Begun Plans for a 2069 Interstellar Mission

$this->bbcode_second_pass_quote('', '[')img]https://i.imgur.com/0GJZ3P8.gif[/img]

In 2069, if all goes according to plan, NASA could launch a spacecraft bound to escape our solar system and visit our next-door neighbors in space, the triple-star Alpha Centauri system, according to a mission concept presented last week at the annual conference of the American Geophysical Union and reported by New Scientist. The mission, which is pegged to the 100th anniversary of the moon landing, would also involve traveling at one-tenth the speed of light.

This isn't the first time the idea of visiting Alpha Centauri at that speed and on that timeline has been suggested. Last year, House of Representatives subcommittees considered a bill suggesting a mission to Alpha Centauri, although that text never made it into an approved law. But NASA is still hopping on board with the idea, with a probe that might be able to spot alien life.

We already know there's at least one planet in the neighborhood, Proxima b. And scientists suspect there may still be more planets about the size of Earth in the neighborhood left to find.

U.S. Lawmaker Orders NASA to Plan for Trip to Alpha Centauri by 100th Anniversary of Moon Landing

$this->bbcode_second_pass_quote('', '[')b]Science: Today a senior U.S. lawmaker who helps write NASA’s budget called on the agency to begin developing its own interstellar probes, with the aim of launching a mission to Alpha Centauri, our nearest star system, in 2069—the centenary of the Apollo 11 moon landing.

Representative John Culberson (R–TX), a self-professed space fan who chairs the House of Representatives appropriations subpanel that oversees NASA, included the call for the ambitious voyage in a committee report released today. The report accompanies a bill setting NASA’s budget for the 2017 fiscal year, which begins 1 October; the full House appropriations panel is set to consider the bill on Tuesday.

In the report, Culberson’s panel:
$this->bbcode_second_pass_quote('', '[')b]“... encourages NASA to study and develop propulsion concepts that could enable an interstellar scientific probe with the capability of achieving a cruise velocity of 0.1c [10% of the speed of light].”

The report language doesn’t mandate any additional funding, but calls on NASA to draw up a technology assessment report and conceptual road map within 1 year.


After the Moon and Mars, NASA Wants to Head to Alpha Centauri in 2069

NASA: Mach Effects for In Space Propulsion: Interstellar Mission

$this->bbcode_second_pass_quote('', 'I')nitial Phase I effort will have three tasks, two experimental and one analytical:

- Improvement of the current laboratory-scale devices, in order to provide long duration thrust at levels required for practical propulsion applications.
- Design and development of a power supply and electrical systems to provide feedback and control of the input AC voltage, and resonant frequency, that determine the efficiency of the MET.
- Improve theoretical thrust predictions and build a reliable model of the device to assist in perfecting the design. Predict maximum thrust achievable by one device and how large an array of thrusters would be required to send a probe, of size 1.5m diameter by 3m, of total mass 1245 Kg including a modest 400 Kg of payload, a distance of 8 light years (ly) away.

... A mission to Planet 9 (or Planet X as it has been called) is possible in the near future using RTG power and thruster arrays. A future goal would be interstellar travel to the nearest exoplanet, within 5-9 ly distance. A mission of this type might take 20 or more years using the MET thruster. Although the nearest exoplanet is 14 or so ly distance, more Earth-like planets are being discovered daily.

What is the Alcubierre "Warp" Drive?

$this->bbcode_second_pass_quote('', 'S')ince Einstein first proposed the Special Theory of Relativity in 1905, scientists have been operating under the restrictions imposed by a relativistic universe. One of these restrictions is the belief that the speed of light is unbreakable and hence, that there will never be such a thing as FTL space travel or exploration.

In 1994, a Mexican physicist by the name of Miguel Alcubierre came along with proposed method for stretching the fabric of space-time in way which would, in theory, allow FTL travel to take pace.

To put it simply, this method of space travel involves stretching the fabric of space-time in a wave which would (in theory) cause the space ahead of an object to contract while the space behind it would expand. An object inside this wave (i.e. a spaceship) would then be able to ride this region, known as a "warp bubble" of flat space.

This is what is known as the "Alcubierre Metric". Interpreted in the context of General Relativity, the metric allows a warp bubble to appear in a previously flat region of spacetime and move away, effectively at speeds that exceed the speed of light. The interior of the bubble is the inertial reference frame for any object inhabiting it.

Since the ship is not moving within this bubble, but is being carried along as the region itself moves, conventional relativistic effects such as time dilation would not apply. Hence, the rules of space-time and the laws of relativity would not be violated in the conventional sense.

One of the reasons for this is because this method would not rely on moving faster than light in the local sense, since a light beam within this bubble would still always move faster than the ship. It is only "faster than light" in the sense that the ship could reach its destination faster than a beam of light that was traveling outside the warp bubble.

Image

Mathematically, it can be represented by the following equation: ds2= – (a2 – BiBi) dt2 + 2Bi dxi dt + gijdxi dxj, where a is the lapse function that gives the interval of proper time between nearby hypersurfaces, Bi is the shift vector that relates the spatial coordinate systems on different hypersurfaces and gij is a positive definite metric on each of the hypersurfaces.

In 2012, NASA's Advanced Propulsion Physics Laboratory (aka. Eagleworks) announced that they had began conducting experiments to see if a "warp drive" was in fact possible. This included developing an interferometer to detect the spatial distortions produced by the expanding and contracting space-time of the Alcubierre metric.

The team lead – Dr. Harold Sonny White – described their work in a NASA paper titled Warp Field Mechanics 101.

2016 BREAKTHROUGH PROPULSION WORKSHOP PROCEEDINGS

Chinese Physicists Measure Speed of Einstein’s ‘Spooky Action at a Distance’: At Least 10,000 Times Faster than Light

$this->bbcode_second_pass_quote('', '[')b]A team of Chinese physicists have clocked the speed of spooky action at a distance — the seemingly instantaneous interaction between entangled quantum particles — at more than four orders of magnitude faster than light. Their equipment and methodology doesn’t allow for an exact speed, but four orders of magnitude puts the figure at around 3 trillion meters per second.

Spooky action at a distance was a term coined by Einstein to describe how entangled quantum particles seem to interact with each other instantaneously, over any distance, breaking the speed of light and thus relativity. As of our current understanding of quantum mechanics, though, it is impossible to send data using quantum entanglement, preserving the theory of relativity. A lot of work is being done in this area, though, and some physicists believe that faster-than-light communication might be possible with some clever manipulation of entangled particles.

Now, thanks to these Chinese physicists — the same ones who broke the quantum teleportation distance record last year — we know that spooky action at a distance has a lower bound of four orders of magnitude faster than light, or around 3 trillion meters per second. We say “at least,” because the physicists do not rule out that spooky action is actually instantaneous — but their testing equipment and methodology simply doesn’t allow them to get any more accurate.

To get this figure, the physicists entangled pairs of photons at a base station, and then transmitted half of each pair to two receiving sites. The receiving sites were 15.3 kilometers (9.5mi) apart, and aligned east-west so as to minimize the interference from the Earth’s rotation (which is significant, when measuring speed on this scale). One half of the pair was then observed, and the time for the other half to assume the same state is measured. This process was repeated continuously for 12 hours to generate enough data to accurately divine the speed of spooky action.

According to the physicists, other research groups have tried to measure the speed of spooky action before, but they’ve all had locality loopholes — flaws in the methodology that undermine the quantum nonlocality that the experiment requires. This time, the physicists claim, all the loopholes have been closed, and that their measurement of at least 3 trillion meters per second is accurate.

Comment:
$this->bbcode_second_pass_quote('', '[')i]... I was on board the USS Princeton (2001-2005) when this all went down. We actually went to GQ (General Quarters) for about 4 hours as all if this was going down. I’ve been telling everyone about this even, but have gotten the usual “yeah right” look when I tell them about it. I saw the video after it happened, but didn’t think that it would somehow make it’s way to the public, considering all of the “security” that surrounded the issue.

Crazy how the world turns, isn’t it?!

Thank you for giving this event life! I no longer look like a tin foil hat wearing idiot!

1952 Washington, D.C. UFO incident

Image

$this->bbcode_second_pass_quote('', '.').. The report is called "A Preliminary Study of Unidentified Targets Observed on Air Traffic Control Radars." The report was issued by the Civil Aeronautics Administration in 1953.
$this->bbcode_second_pass_quote('', '[')b]... "If there are UFOs and they want to make themselves known, land! And if they don't want to make their visits known, turn off the lights!" ... "If UFOs are abducting people, why do they choose only ugly people? If they abducted Olympic athletes, I could understand."

Bruce Maccabee, 60, is a civilian physicist for the Navy and believes there were "solid objects" in the air over Washington 50 years ago. "And I think those solid objects were not made by us," he says. "And by us, I mean human beings."

Like Klass, Maccabee buttresses his argument with an official government report. It's called "Quantitative Aspects of Mirages" and it was issued by the Air Force in 1969.

"They proved in their own study that there wasn't enough temperature inversion to cause this effect," he says. "The Washington sightings cannot be explained as a radar mirage."

Former controller Howard Cocklin is still convinced that he saw an object over National that night. "I saw it on the screen and out the window," he says. "It was a whitish-blue object. Not a light -- a solid form. An object. A saucer-shaped object."

Now 83 and retired, Cocklin says he never saw anything like that saucer -- not before, not since.

The light from this star flickers, like a giant neon sign drifting through the constellation Cygnus. After the star's dim intervals, which last for days or weeks, it brightens again.

No other star acted this way. No observation could explain its behavior.

That is, until now. A 200-strong team of scientists says it has arrived at an answer, thanks to an astronomy project crowdfunded on Kickstarter. The culprits are not aliens, as some people have speculated, but probably a cloud of dust, each particle less than a micrometer across. Combined, these dust particles coalesced into one of the biggest question marks in recent astronomical memory.

$this->bbcode_second_pass_quote('', '[')i]"Dust is most likely the reason why the star's light appears to dim and brighten," study leader Tabetha Boyajian, an astronomer at Louisiana State University, said in a statement. "The new data shows that different colors of light are being blocked at different intensities. Therefore, whatever is passing between us and the star is not opaque, as would be expected from a planet or alien megastructure."

Whatever substance exists between us and Tabby's Star blocks more blue light than red light, as Boyajian, Ellis, Wright and other researchers reported in a study published in the Astrophysical Journal Letters on Wednesday. Planets cannot explain the dips. “If you have something that is completely opaque like a planet, you would expect all the colors of the light to be blocked out at the same levels,” Boyajian said. Likewise, the discovery also rules out alien industry.

“It has the typical signature of dust,” Boyajian said.

Yet even in space dust, there is mystery. If it is dust, the dust cloud has not spread far beyond its point of origin, the authors noted in the paper. A ring of dust around the star would constantly block starlight rather than dim light in bouts.

Insensible before the wave so soon released by callous fate. Affected most, they understand the least, and understanding, when it comes, invariably arrives too late.

(The original book in the series 'Gateway' is a masterpiece of science fiction)

Or as Q said in the STNG episode he became human, re the problem of needing to change the path of a moon threatening a populated planet:

This kind of discussion reminds me that to me, the main regret I have about dying in a couple-few decades or so is not getting to see all the cool stuff that happens due to technology. (As a fan of astronomy as a child I NEVER would have imagined a booming field in studying exoplanets, or even identifying one with certainty.)
Given the track record of the perma-doomer blogs, I wouldn't bet a fast crash doomer's money on their predictions.
