Is Extraterrestrial disclosure taking place?

Then you’d be wrong and I’d suggest watching.

OK, against my better judgement, I will watch it and give you my considered view - FWIW - later.

I find not dismissing things which are nonsense, to be quite stupid.

Extraordinary claims require extraordinary evidence, and there is none.

Small-minded. Think outside the box. We are extremely primitive in the scheme of things.

We are extremely primitive in the scheme of things.

Are we ? we might be, but there is also no evidence we aren't the most advanced race there is or has ever been in the known universe. Not a scrap of evidence.

Small-minded. Think outside the box.

Have you?

Have you considered the (IMO cast iron certainty) that all these stories are in fact made up, hoax's or just one or two genuinely puzzling sightings, but which do actually have a pretty mundane explanation behind them?

Suggest you open your mind to that possibility!

And BTW @HelloCity: Sorry i got 10 minutes in and turned it off. It was utter tripe. I've seen more convincing episodes of Dark Skies and that was a fictional drama series.

There are probably something like 2,000,000,000,000,000,000,000 planets out there in our observable universe. 99.999999999995% of which are not even in our own galaxy, and therefore are more than 25,000 light years away. (Actual best current estimate figures, not made up nonsense.)

And we are to believe that some beings, who when setting out, had no clue that our planet had any life on it at all, have nevertheless decided to venture out to visit Earth?

It's just bullshit, pure and simple.

It’s wrong to entirely rule it out. Survival is a great motivator.

When our own star begins to die I would imagine our technology would have advanced exponentially, the new IPhone 2bn will be available in pink for the first time, and we will be contemplating our own survival - one of the most basic instincts there is. The concept of launching probes to seek habitual planets followed by a limited “manned” mission to confirm suitability of identified candidate planets would seem a rather sensible way of doing things prior to a mass evacuation to said new planet.

You have to remember that even with life evolving at the same rate as it did on earth there is the potential for civilisations 1bn years older/more advanced than us.

Not speaking for them but I think Primitive wasn't the right term. Young is. in the galactic time scales we have gone from Neanderthal to space flight in the snap of a finger.

But as you say, zero evidence any other race has done the same.

And why would such a civilization choose our planet when there's another 2,000,000,000,000,000,000,000 (at least) potential candidates out there, the the vast majority of which - statistically - will be much closer to them than we are. Even if only 1 in a million planets is habitable - or even potentially habitable (and that would seem like a very, very small proportion for a race so incredibly advanced that you'd think spot of terra-forming would be like a walk in the park) - then that's two thousand trillion habitable planets to choose from. Why choose ours?

And even more importantly, where are these aliens? Where's the evidence - actual hard evidence - that they have been here? Cave paintings? Do me a favour. "Sightings?" Ditto. There is no evidence. Just hearsay from frankly a bunch of deluded types or liars.

I think technically, commercial jets fly supersonic every day without creating a sonic-boom, because they fly faster than the speed of sound in relation to the ground, but not in relation to the air, which is what causes the sonic boom sound.

When you go supersonic, the speed you are going at is only part of the equation. The International Space Station is flying at 17,500mph but it isn't flying around at supersonic speed because there is no air and so there is no shockwave.

Supersonic has always been defined as anything above Mach 1 but the Mach number depends on the local properties of the speed of sound in the air (and again in space there is no air). That's why you can't hear anything in space, because there is no medium for sound waves to travel through and so there are no shockwaves in that sense. The space station really is therefore flying at Mach 0 and so not supersonic.

Imagine it like this, if you stick your hand outside a moving car you'll feel resistance. If you go very fast (500mph+!) then shockwaves will develop from your hand in the airflow as you go supersonic. Take away the air though and you'll feel nothing but the car will still be moving.

Commercial planes are indeed flying a lot faster up at cruising altitude than on the ground but they aren't necessarily breaking the sound barrier because the air is much thinner. Planes typically cruise at a bit more than 3/4 the speed of sound but if they went anywhere beyond that then bad things would start to happen.

In aviation we call that coffin corner, it's where the plane is basically going too fast and cannot generate lift from it's wings because of the interactions from shockwaves.

I think humans will be long dead by then, there's virtually no chance that we won't see several extinction events over the next few billion years. At the moment we are slowly walking into one of our own making with climate change, overpopulation etc and that's after just 200 years or so of advancing industrialisation.

Basically we are far too stupid and sh*t of a species to work out how to survive beyond our own lifetimes let alone preserve the planet so that others can do the same.

speed of sound is all to do with air density etc etc so depends on air speed and height. higher up the higher the sound barrier as the air density is lower.

For example. Felix Baumgartner, the guy who sky dived from the edge of space managed to hit 843.6mph which is technically faster than the sound barrier... but it wasn't fo him. he didn't break the sound barrier as the increasing density of the atmosphere slowed him down.
