.. . . . . . . . A chain of 'IF's can soon have limited validity. IF I won the lottery and IF a unicorn landed and IF I were awarded a Nobel prize is hardly a good start to a conversation unless we are discussing a fantasy fiction plot. PF has a forum dedicated to this stuff for good...

When you use 'numbers' you lose the pattern of what's going on (it was a blur to me and I eventually found that difference). @Orodruin 's post has a full description but I suspect you may also have find it a blur - but it is correct and sufficient. Here's a limited version which may be easier to...

'Outliving your home star' involves timescales of many hundreds of millions of years. What Earth organisms have had that sort of lifetime and also had high tech? Humans, after just a few hundred years of tech, have been on the brink of self destruction for some while. We'll be hell and gone long...

What exactly do you mean by this? What form do your experiments take? Is there any hardware or is it all on a simulator (which someone else wrote)? So that's all they've achieved? They must be glad that you are around to put them on the right lines.

I was beginning to wonder about Ephant. I was thinking tinfoil hats etc..

or even interplanetary, Thing is that Earth was absolutely bone dry to start with (as was Mars). We both accreted lots of water (comets) but Mars mostly lost it. We think of water as being 'special' to us (blue planet etc,) but it's all over the place. Often much easier to extract than to...

Lol. Two very common elements which react well together. tumteetum. There's a lot of it in the Oort cloud and the aliens would pass through it on their way to Earth. Oh, and yes - they would have their own Oort cloud around their own star.

Are you planning a DIY solution? Do you have skills and equipment. This is a non-trivial project. I remember organising a similar sort of device as a demo on a TV 'Science' programme. They used a rocking cradle ( borrowed for free because the broadcaster is a excellent scrounger) and an old...

So far, despite having posted a number of screen shots, you haven't yet said what you mean by noise floor. What does that mean in grown up language?

I'd have to disagree there. AM is such an inefficient mode that any species that had only got that far would be of no interest to us and wouldn't be capable of useful comms. We would need to be looking for a signal with very much noise-like characteristics which would carry (amongst other...

Consider the probability of peace on Earth And we're all pretty similar and with the same aims. Little green men are very unlikely and friendly ones even less so.

Before you make many gaffs, perhaps you could say how Noise Level is defined and measured. Merely looking at a fuzzy scope trace tells you nothing because it’s random!

How do you know? What is the internal reference voltage? If it's not exactly the same as your maximum input signal then there will be some amplification somewhere. You are clearly so far out of your depth that you don;t even know which of your ideas are righand which ones are wrong. There you...

Some things require a lot of repetition. water dripping on a stone.

I can't see any points A and B . . . . . yet. Voltage is Potential Difference; the difference on potential between two points. Any chosen point on a circuit has no 'Volts' until referred to another point.
