Do Aliens actually exist ?

Great series on late at night at the moment 'Nasa Unexplained' features real, official people and declassified cia doc's.

i'd like to know what a interesting and non boring planet is like if we're not,

and as for the debate infinite/finite, does it matter at this point which it is as we are still at observable universe, too dam big anyway

The point is, until we started emitting radio waves, our planet is no more significant than any other 3rd rock from a sun, and given there's 100 billion or so suns just in our own galaxy, let alone the hundreds of billions of galaxies, no alien would find anything to cause them to be interested in looking our rather insignificant planet.

On closer inspection, of course it's very interesting and probably quite significant. But there would never be a first inspection, so they'd never know.

Kurzesegat is one of the best content creators on the internet (much less YouTube) in my mind. They have primers on all sorts of subjects and they spend exceptional amounts of time on research for even the shortest segments of the videos.

Their content is meant to be stepping stones to more in-depth learning (and I think they do that job very well, as they’ve certainly sent me down the rabbit hole on many occasions) but, even if you only watch the videos and go no further, you are still more well-informed/educated then a great many on that particular subject (even if you may not agree with everything they assert, as they do political and economic content, as well).

Suffice it to say, I financially support their work.

Really good teaching tool to inspire thought and discussion in a classroom (obvs could be abused propaganda-wise). No teacher has the time to prepare something like that. Possibly why we had that weird sex video when we were 16.

Must add for everyone - Bluemoon podcast benefits from Patreon too. Give them your £1 Ederson to score first.

Hear, hear.

@twosips could use the financial support, as well, especially as he is still working to pay off the debt incurred from the experimental alien probing surgery.

It's a possibility vs probability thing.

It's tempting to think that because of the huge and almost unimaginable scale of the universe that alien life is very likely or highly probable. It seems a very reasonable assumption.

However, that probability only comes into play when we know that life outside of this Earth is possible. For all we know, life might be something unique to Earth. If we discover signs of life on somewhere like Mars or Titan, then we would only know that it is possible within our solar system.

In other words, until we find a sign of life beyond this Earth or preferably beyond this solar system, the size of the universe doesn't really give us any probability.

And yet...I can't help but feel that there are aliens out there, even though I know that we aren't certain that it's possible, because the universe is so big! It's a real mind-shag.

When I read some other threads in Off Topic I think it's definite that there are aliens amongst us.

i get all that, so in essence we are a interesting little rock but the chances of us being found let alone being investigated is a remote one and vice versa hence my previous comment of everyone missing each other because of the vastness of the universe

these numbers are mind blowing on there own and this is just our galaxy

In November 2013, astronomers reported, based on Kepler space mission data, that there could be as many as 40 billion Earth-sized planets orbiting in the habitable zones of Sun-like stars and red dwarfs in the Milky Way,[5][6] 11 billion of which may be orbiting Sun-like stars

Yes the universe is ridiculously big, but some events are also ridiculously unlikely.

For example, take a shuffled deck of 52 cards, and suppose we try to randomly guess the sequence. For each guess, we'll take one atom and throw it away. Then take the next guess and use another atom.

How many atoms do we use up, before we guess the right sequence? The answer is, give or take, all the atoms in the entire galaxy. The numbers of possible combinations of the deck of cards is circa 10^^68 And the numbers of atoms in the galaxy is "only" 10^^67.

Another way of looking at this is that randomly trying 1 million sequences per second, it would take you 231,000,000,000,000,000,000,000,000,000,000,000,000,000 times the age of the universe to guess the sequence.

If getting a random combination of atoms which can actually replicate and evolve is anything like this unlikely, we're in trouble! I've no idea whether this is the case or not, btw.

Just for fun - blurb for 'Zero : The Biography of a Dangerous Idea' by Charles Seife. Might suggest that, that which is seen as 'alien' can be a threat to the status quo (thus feared and labeled and dangerous/mad etc) yet can come to be seen as a catalyst for expansion/'rebirth' into new paradigms.


"Within the concept of zero lies a philosophical and scientific history of Mankind. The Babylonians invented zero, it was banned by the Greeks while on the eve of the Millennium zero was feared to be a timebomb within the world s computer systems. There was a time when zero did not exist, the concept of zero is a relatively recent Eastern concept and for centuries there was a struggle over its very existence. For many cultures zero represented the void and it could prove to undo the framework of logic. It was seen as an alien concept that could shatter the framework of Christianity and science yet European acceptance of zero as a philosophical concept was at the centre of the Renaissance.Over three thousand years the concept of zero has been at the heart of the intellectual debates that have created our culture. In the first millennium zero lay at the heart of the debate between Eastern and Western religion, while after the Renaissance zero was at the centre of the struggle between religion and science. Zero s power comes from its ability to disrupt the laws of physics and it may hold the secret of the cosmos. From the nothingness of a vacuum came our universe, if our universe was born in zero so zero could hold the existence of an infinite number of other universes. .
