Are we not far away from discovering alien life

While I kinda agree with you there have actually been 5 mass extinction events, and a sixth is currently underway.

snip.


I'll read the article later thanks for the info. Interested in the other extinction evens. I have a passing interest in Space the universe etc and how it all works. Never really read up and got to the finer details. Possible life and the work to find it in the universe and quantum physics really peak my intrest, black holes, dark energy and dark matter..

I mainly referred to humans as a species and yes how each species, and the diversity of life that could possibly be in the universe, would have advanced technology is dependent at the rate they find resources, understand and develop technology. Not just technology like computers but sharpening a stick to make a weapon to hunt is also very important.
Given that at some point whatever type of "Alien" we are to them as they are to us, we/them must reach a point of being able to transmit or detect or even "if they find us first" develop to the point of interstellar travel.

The current mass extinction is by far the most aggressive and destructive of all of them!


I wrote this some years ago for some reason! :/

I suspect that in 100 million years time (assuming there are palaeontologists around to examine it) the fossil record corresponding to the 20/21 century will show the sudden deforestation of the entire planet and, in the blink of a geological eye, the extinction of almost all animals with a body weight greater than 25Kg, (with the exception of around half a dozen species whose population exploded!)

This represents a breadth, depth and rate of mass extinction that dwarves even the Permian-Triassic extinction (AKA the "the Great Dying")

If all this seems a bit pessimistic, it is worth noting that this has pretty well already happened over much of the developed world.

Unless something pretty dramatic happens over the next couple of decades the process will be largely complete, globally, within the lifetime of people alive today!

"Climate Change" is an utterly insignificant issue by comparison!
 
I believe humans were brought to this planet by aliens they will cone back to visit us we don't need to look for them.
 
Our civilised history is but a blink in the eye of the universe. Unless intelligent beings exist in the same time frame as us and with the capability of travelling to our planet whilst we are still here, then we will simply miss them like passing ships in the ocean.
 
We are nowhere near finding other forms of life. The evidence we have suggests that life appeared on this planet only once in its 4.5 billion years of history. That suggests its an incredibly rare occurance.

But the fact that it appeared almost as soon as life could survive on the planet suggests that is not terribly unlikely where the conditions are right.
 
Quick google seems to cover th basics.

Chance of finding non carbon life is pretty much zero.

Although the most likely form of intelligent alien beings mankind will encounter, if ever it will, will be robotic in nature. Robots could survive for so much longer than biological forms. If we can ever make sophisticated enough machine intelligences then they could survive the length of journey to other star systems carried by craft that we already have the technology to make.

We are Borg, you will be assimilated!

:p

Actually, I agree, this is the most likely form of life that we are actually likely to physically encounter.
 
Aliens are among us but in the distant future they will make themselves known. They actually communicate through nervous system they orbit earth in a near orbit. They call themselves George.
 
I find the whole,Planets and outer space thing weird..i mean whats the point in it all if it doesn't serve a purpose,I do also believe there isn't only us out there.

But makes me also wonder,theres also been sightings of unexplained objects in the sky and around out planet before,Why have they never made any attempt to communicate with us..questions questions. :D
 
When I was young teenager, I used to be quite open to the possibility we already were being visited by aliens, mostly in regards to roswell, unexplained sightings, things that former presidents have said like jfk and Reagan, code speak concerning various phenomena over radio transmission during the apollo missions etc etc. However as I've gotten older, the whole concept of aliens being already amongst us and it being a big conspiracy seems absolutely ludicrous to me now.

Even some of the best evidence, which some conspiracists stand by, in my opinion is explainable if you look at it objectively. True, there are some things which are not explainable, but that does not automatically make it alien in the view of it being extraterrestrial either.

I'd certainly like to think somewhere out there, we are not alone, but locally in our solar system? It seems more and more unlikely, but perhaps more likely further out in nearby systems like Alpha Centauri, which is probably our best bet for now.
 
There is most likely life out there in some form. With a universe so vast its ridiculous to think otherwise. That life though doesn't need to look like us. Movies show most aliens to be humanoid in nature with 2 front facing eyes, nose under eyes the a mouth, 2 hands two feet etc. Its ridiculous to think other life on different planets would evolve in the same basic way.
We are only different to monkeys by 2 croamasones (sp) the smartest being on par with human infants. What's to say other life doesn't for example have 2 extra and we are on par with their infants? What about dna? Why do they need dna? Life could form in many different chemical ways that we don't know of and wouldn't be looking for because it doesn't register as life to us.
Who to say intelligent life isn't self destructive and goes extinct due to the nature? Anything could happen.

I dont believe we will discover life on other planets as i dont think we will survive that long. Rather grim way of looking at things but don't see how its going to be different.
 
Given the estimated number of stars to be 100,000,000,000,000,000,000,000 I think it is safe to say there is life on another planet.

No, it isn't.

We know almost nothing about almost all of the factors involved. It's not safe to say anything certain about the subject.

How many stars have potentially inhabitable planets? We have no idea.

What is the chance of life evolving on a potentially inhabitable planet? We have no idea.

How many of those planets (if any exist) have been stable enough for long enough for life to start? We have no idea.

And that's without considering evolution at all, just biogenesis. Nor does it take time into account - the existence of life elsewhere at some point in time isn't the same as the existence of life today. There has been plenty of time for life to exist, evolve and become extinct.

We know that it has happened here - that is plenty evidence enough, given how common Earth-like planets turned out to be, and that you have an entire universe out there.

Life definitely exists on other planets. 100%. However, us meeting any of them? Now that's slim to none.

You're assuming that there is a point. Why?

i) "unexplained" doesn't mean "made by intelligent aliens with advanced technology".

ii) If aliens could come here, then their technology is vastly more advanced than ours. That alone would probably ruin humanity in the event of contact. They might want to avoid taking that risk. Or they might not see as as being people they want to talk with, either because we're inferior to them (there's no reason to think that humans are the highest possible form of life) or because our societies are inferior to theirs and they are worried about cultural contamination. Or they might be worried about diseases. Or they might be worried that humans would rapidly acquire advanced technology and use it to invade them.
