oh i think that's a load of rubbish tbh

I agree with this. I have no doubt that the is other life out there somewhere, but I've seen nothing to indicate they have any better chance of getting to us than we do of getting to them.

even if just 1 of those 500,000,000 earth like planets in our solar system harbours intelligent life

There are not 500,000,000 earth like planets in our solar system. There is one, it's called Earth.

Whos to say an advanced species havent done just that with us/earth?

Let's assume you meant our Galaxy. That would mean there were 2 planets with intelligent life if you count Earth. That would mean the odds of hitting the right planet with a probe would be 1 in 250,000,000. If you don't count Earth it's 1 in 500,000,000. Not too good.

Debunkers like me are usually people that once believed that UFO's were piloted by aliens from outer space.
We done the research and slowly came to know that Earthly UFO's are just that . Unidentified craft of Earthly
origin.

It has suited our goverments to pay into the Alien UFO phenonama to hide their secret black op experimental
craft.Disonfo if you like.

Aliens are plentiful...out there, but they are out there and not here.

Why can't you possibly accept two dichotomies happening at once? That's like saying, you once believed all fish were harmless until you saw a shark. Now you know all fish have teeth.

There are absolutely man-made UFOs (aren't you glad your government has 'transparency' now? ). However...it's not all or nothing. They got that technology from somewhere.

The technology we have is all Man Made. And still primitive. Our space craft at this time would take ten's of years just to get beyond our own solar system.

As for wether aliens have visited us or not, even if just 1 of those 500,000,000 earth like planets in our solar system harbours intelligent life is it that unlikely that they could have (in exatly the same way we have) explored the universe with probes and scopes etc.

Imagine if we sent a probe close enough to get shots of that planet we have recently discovered and found that it had oceans, clouds and an atmosphere etc. The 1st thing we wouuld do would be to get a closer look when technology permitted it. Whos to say an advanced species havent done just that with us/earth?

You don't even know the contents of our own Solar System, but you think your self qualified
to comment on the likely hood of aliens visiting Earth or otherwise existing elsewhere.....lol

Just saying there's lots of planets in the habital zones in the universe is no guarantee of life.

Life may seem very diverse on our planet but everything with DNA is related. Its all been developed for the same one ancestor or organism. If is common on our planet but independent development of life is not. This is true on a planet that has what we consider to be the perfect conditions for the development for life.

It may be that life only developed on earth over millions of years of very specific processes that happened in a very specific order. If that's the case then the chances of there being life on other planets would be very , very, very remote.

What do you think of this report Phage?

Until recently, astronomers could only guess at the number of stars with planets around them. Now, with the more than 700 confirmed exoplanets, researchers finally have enough data to begin homing in on the true number

10 Billion Earth-Like Planets May Exist In Our Galaxy
I recognoze the word may, but within this enormous estimation, surely there are more than just 2 in our entire galaxy. I do realize only 2 have been confirmed in the 'inhabitable zone," but I speculate there is more amongst the 700. I know, speculation is just that, but is still fun to imagine...

theyre talking about red dwarf stars though. Problematic for earth-like planets.

Problematic for earth-like planets.

But those may still support earth like planets, even though their habitable range is closer because a red dwarf is not as hot as a sun.

The search found nine planets with between one and 10 Earth masses, including two in the habitable zone, possibly giving them the right temperature to have liquid water. Because red dwarfs don’t produce as much heat as our sun, their habitable zones occur much closer to the star.

A previous team suggested that one quarter of sun-like stars have an Earth-sized planet around them, while another group estimated that one planet exists for each of the hundred billion stars in our galaxy.

Either estimate leads me to believe there will be more earth-like planets discovered in our galaxy.

current kepler data puts the number of earth size planets in the hz of sun-like stars at 3% its still a bit of a guess but we will have the real number soon. Be shocked if its higher than 10%

reply to post by speculativeoptimist

I was just using his figures.

Yup. A lot of planets out there. But the definition used for Earth-like is a rocky planet close in mass to Earth at friendly distance from its star. It doesn't mean it has water or even an atmosphere. Those are two somewhat important factors but I'm sure there are plenty of planets that have them.

I'm pretty sure there is life elsewhere, and a very good chance there is intelligent life too. Not sure how much life or how much intelligent life though. That's a hard call to make.

Why? Just cooler than our Sun which means the habitable zone is a bit smaller and closer in.

reply to post by Phage


being closer in brings some of its own problems. In the HZ of a red dwarf the planet will become tidally locked meaning 1 side will face the parent star all the time and the other half will be permanent dark (cold). One side fries while the other freezes

If your really close to smaller m stars in their HZ the gravitational forces exerted by the parent star could cause internal & surface disruption to the planet. (quakes) not a good place to build a house. They might well have oceans of magma rather than water like here on earth.

M stars are much more active than g type stars like sol. Variability in the output could cause havoc for complex life.

but it makes me wonder what these places are really like

Got any links or sources for that show buddy.. Thanks.

Course there is life out there, it goes without sayin... I agree with the poster who thinks the Ufo's etc are probes or some kind of servailence system, just like Curiosity landing on Mars today..

Great topic and subject matter! S&F!

It's to wrap my brain around these numbers. Once I breach a million I'm lost. Lol. It's hard to believe that, with the numbers being in the millions and billions, the UNIVERSE does not contain other forms of life; both sentient and non-sentient. I look at it like this, If God created us, and the bible is the story of our origins, why is there no stories about the stars or other planets, or outer-terrestrial bodies, like comets, stars, planets, etc, etc. Perhaps the bible does discuss this; I don't know. However, if there is no god, then there really is nothing special about us; nothing that could not be replicated in similar or different conditions elsewhere in the universe. What makes us think we are the pinnacle of sentient life anyways? Because I can wipe my own rear end?

1% of 5,000,000,000 is 50,000,000.

Just saying. Good thread though.

The problem with this line of reasoning is sheer ego. Just because WE can't do it does not mean a intelligent Alien race with say, a hundred thousand year head start, cannot. Their technology would seem like magic to us at first glance. There are far too many possibilities and variables to outright conclude that because WE can't do it nothing can.

Not to mention if we discovered a habitable planet in another system we would probably send probes or other unmanned craft to investigate eventually. We have/ will have the technology to do so. However our understanding of space and time is in its infancy. A race older and more advanced would definitely have answered questions that perplex us. And solved other questions we haven't even asked yet due to our limited understanding.

So your flawed line of thinking is rather close minded.

Impossibility is a human invention. And human inventions often fail.

The average person cannot get past the differences in another human.

People rarely think beyond their city, state, region, coast, country, etc;

Why would anyone that calls another human, a separate race, stop to think that there may actually be other sentient beings in the universe?

Another problem I have is the argument that conditions must be perfect. Much like our own. And truth be told that is nothing more than a guess. Just because a planet is tidally locked to its star, or a little closer and hotter, or its atmosphere mainly being methane instead of carbon dioxide does not mean life of SOME form could not evolve and flourish there. Once again that is another problem that stems from our limited knowledge of the Universe and Astrobiology. We cling too tightly to our preconceived notion of life and how it can form. Instead of thinking outside the box and asking questions that are deemed Impossibility or just plain craziness we prefer to stagnate until some discovery smacks science in the face and forces their hand.

I love science and all the knowledge it brings. I hate how it is empirically controlled and anyone who proposes theories that don't jive with the mainstream are labeled quacks or kooks and shunned from the tightknit circles that make up the majority of mainstream scientists. People with supposedly outlandish theories are labeled New Age charlatans etc. It really hinders advancement of our species when new ideas are simply discarded because science refuses to possibly have to change their deep seeded "Truths".

In these times....

On this planet alone a mere dust ball compared to size of the universe, with all the millions of different life forms on it and people can't grasp that thier is life our there.

Just plain ignorant.
