While I am hugely doubtful that aliens have visited Earth, we cannot discount it.
The chances of there "not" being other intelligent life in the universe is slim to none. The chances are there are many.
If there are many then some of them will be far more advanced than we are.
In which case they may be able to get around Einsteinian theory...worm-holes etc?
So, while I think that between 99.9999% and 100% of reported UFOs claiming to be aliens are false, usually from crackpots, the idea that some of them are real, is possible...
Unlike ghosts of course...which in 100% of cases is certainly not dead people in slightly visible energy form...that, is total BS.
2 objectiins to this - we've been here such a short time life elsewhere should it exist would be so far advanced it would have made contact by now. It hasn't so it's unlikely it exists. Secondly, an infinite universe will contain infinite possibilities so the likelihood of replication is remote. We only thnk 'life' is important because we think the universe revolves around us. It doesn't.
1st prize for the most misdirected post of the week.
1. The Universe is BIG.
2. So there are other races, far in advance of ours. Maybe they have been here. If they are "so far in advance" then maybe they simply left us alone
3. Maybe they haven't been here. The Universe is BIG remember.
4. Maybe there really isn't a way round Einsteins laws.
5. The Universe is not "infinite", at least according to current thought.
6. Where on earth (npi) did I say life was important? No. It isn't. Nothing is (in the scheme of things). Humans are a blip. Nothing more. The Universe has been around for 14 Billion years and will be around for quite a bit after we are gone.
1. You don't say
2. Without evidence this is speculative
3. 'They' don't have to have been here - NASA has been sending a stream of signal into outer space for some time now - zilch response
4. The Universe doesn't operate according to any laws devised by Einstein which in any case aren't laws but simply working hypotheses until a better explanation comes along
5. Your references to 'life' elsewhere and Einstein's laws imply a human-centred view of the universe i.e. one in which human conceptualising holds sway. I was trying to point out that the universe is indifferent to humans such as Einstein and their concepts such as 'life'
The first high powered radio waves sent out into to space was a broadcast of Hitler which happened less than a century ago. Radio waves travel at the speed of light which means they are still less than 100 light years away which is a short distance in astronomical terms. So if there are aliens out there the chances are that none of our signals would have reached them yet.
Also, if radio waves (or any other form of electromagnetic energy) are focused into a beam like a laser which doesn't spread out it will keep its strength over long distances. But almost all of the radio wave transmitions that come from earth are not focused on a target and spread out becoming weaker the further they go (due to the inverse square law). This means that most of the signals sent from Earth will be very weak by the time they reach anywhere of interest and they will be lost against the noise of all the other background radiation.
The only likely way that aliens would be able to see us is if we beamed a high powered and focused beam of radio waves (or any other form of electromagnetic energy) at a precise target in the hope that there is something there to notice it when it reaches them. This has controversially been done already but it will still take many years for the radio waves to reach their target.

It is not known if Einstein's theory's of relativity are correct or not. All that we really know is that either Einstein's theory's of relativity or the laws of quantum physics must be wrong. We don't know which is is wrong as they both stand up to all ot the tests that we have put them through so far. But we do know that at least one of them (or both of them) has to be wrong.
Why do they have to be wrong? Einstein's laws work for big objects, Quantum for small.
And "wrong" is such a strong word here. "adjusted" would be more close to the truth surely?
“Out beyond ideas of wrong and right, there is a field.
I'll meet you there."
Thanks. There's a whole chapter dedicated to the subject in one of my books.
I do think that it's kind of ironic though. If by chance there just happens to be aliens in our local group of stars which are close enough to have received radio wave transmissions from Earth then the first thing that they'll see will be Hitler closely followed by World War 2. It's hardly what you'd call a good advert for the human race. No wonder they haven't come to visit us if that's what they think we're like.
Until we work out a unified 'Theory Of Everything' it's impossible to know if "adjusted" or just plain "wrong" is the right choice of words. It's far too complicated to explain in a forum post but here's a very brief summary on the 'howstuffworks' website: Clicky
If you want to really understand why either Einstein's relativity theories and/or quantum mechanics has to be wrong then here's a book by Brian Cox called "Why does E=mc2?" which explains it all in detail together with the necessary mathematics. Clicky
I could do Alec but maths is kinda alien to me

Of course, that's assuming that aliens can indeed interpret radio waves.

This is true.
First they would need to have a radio telescope pointing in the right drection (although it's possible to make radio telescopes which can see a large area of the sky).
Secondly, they would need to be able to decode the modulated radio waves to get the message.
Thirdly, once they had removed the message from the modulated radio wave they would need to be able to understand and interpret the message.
You presume of course that aliens are at the same technological level as we are, and therefore need to wait for us to send signals to them, as opposed to them monitoring us with technology far in advance of ours, with "intellects vast and cool and unsympathetic"...

They may, of course, be very primitive.
Yes they may. Or they may not. I would say the odds are about 50-50 either way...
Once the aliens start getting broadcasts of the Jeremy Kyle Show they will feel compelled to destroy us.

Forgive me I may be wrong but I was under the impression that Laser beams eventually dispersed.
