Yes, you have. However, the reason you don't remember anything is because I wiped your mind.
Trust no one...
PS - And don't concern yourself with that anal-probing incident. We do that to everyone.
Yes, that was truly horrifying, deeply unpleasant and I never want to be subjected to anything like that ever again!
P.S.: Sorry about my Tennant quote when I was unceremoniously dumped back on Earth....
"I don't want to go!"
There is absolutely no excuse for inflicting any aspect of New Who on an alien culture.
Yes, it's even more objectionable than the poetry of Paula Nancy Millstone.
Have never heard of her, but I just know I am going to look up her poetry now....
SETI scientists spot 72 signals 'from alien galaxy' 3bn light years away
Scientists do not yet know what causes the mysterious fast radio bursts, but a form of alien transportation has been suggested.
Scientists searching for extraterrestrial life say they have spotted 72 mysterious signals from an alien galaxy using artificial intelligence (AI).
The researchers at the SETI (Search for Extraterrestrial Intelligence) Institute discovered the unusual signals when examining 400 terabytes of radio data from a dwarf galaxy three billion light years away from Earth.
Almost all artificial intelligence technology involves automating data analysis, combing through huge data sets to identify patterns or unusual occurrences.
The signals they spotted - fast radio bursts (FRBs) - are bright and quick pulses which were first discovered in 2007 and are believed to come from distant galaxies, although it is not yet know what causes them.
"The nature of the object emitting them is unknown," SETI said, adding: "There are many theories, including that they could be the signatures of technology developed by extraterrestrial intelligent life."

Not sure about the wisdom of this.
Why not just slap a sign on our planet.....
Signals from space: Five theories on what they are
Mysterious signals have been picked up from distant galaxies.
When fast radio bursts or FRBs, as they are called, reach Earth's telescopes they shine brightly for a few milliseconds, then disappear.
Astronomers have detected dozens over the past decade - and have just announced they've found more of them, including a rare repeating signal.
We don't know exactly what they are or where they're from, but here are five suspects:
A rapidly spinning neutron star
When stars explode and die they can end up as rapidly spinning neutron stars. Astronomers think those found in a region with a high magnetic field might produce the strange signals.
"Something like a neutron star fits the bill reasonably well actually," says Dr Ingrid Stairs, an astrophysicist from the University of British Columbia in Vancouver, Canada.
"But exactly what physics is going into producing this very energetic burst of radio waves we don't really know yet."
Two stars merging
Two neutron stars colliding with each other is another possibility.
According to Shriharsh Tendulkar, an astronomer at McGill University in Montreal, Canada, this is one of the main theories, but the scenario only works for cosmic signals that are only seen once, as the stars are destroyed in the process.
"It's a cataclysmic event - it doesn't work for fast radio burst repeaters," he says.
Most of the fast radio bursts picked up by telescopes in the last decade or so are seen once then disappear.
Yet, two elusive signals have been found that burst into life again and again - and for these, there must be a different explanation.
A blitzar is a rapidly spinning neutron star which collapses under its own weight and forms a black hole.
Again, this ends in the destruction of the star, so could not produce a repeating signal.
Black holes are implicated in many theories - from a neutron star falling into a black hole to a collapsing black hole or dark matter hitting one.
Alien life form
While some believe the signals are entirely natural in origin, others have speculated that they could be evidence of extra-terrestrial activity.
Dr Stairs sees this as highly unlikely.
"They come from all over the sky pretty much and many different distances - they must be associated with many different galaxies," she told Newsday on BBC World Service.
"It just seems completely inconceivable that there could be that many different alien civilisations all deciding to produce the same kind of signal in the same way - that just seems highly improbable."
