Do Aliens Exist?

[gspieler]

Lol at "definitive proof", for something we don't even have the ability to study directly. Anyone who's passed an introductory Biology, and Statistics courses(who isn't inherently biased), would acknowledge the likelihood of other life existing in the universe, outside of Earth.

 

[BearGrounds]

I don't think so but Big Foots do exist.

When I was about 6, my father took us camping in the Sierra Nevada. We saw a Big Foot tossing around a boulder the size of a tire like it was nothing. It turned its head towards us and we ran off. It was very scary. Since then, I never had another encounter with Big Foot again.

If you're being serious (which I suspect you are), I'd like to hear any more details to that story you might have to share. Bigfoot/Sasquatch stuff interests me.

Yeah, I think there almost absolutely has to be life out there somewhere, or maybe it's just some shit that we couldn't comprehend even if it was explained to us.

 

[Brodels]

And zero proof after all this study.



This hat that you are pulling numbers out of, did it come with a bowl of soup?

Sure let me send you countless youtube links and articles you can google yourself. You don't want to believe or accept it so why would I waste my time doing that? I don't argue with or try to convince hard headed closed minded people about anything.

Watch this and tell me how it isn't possible for multiple forms of intelligent life to exist somewhere out there. This shit is mind blowing. Humans really can't comprehend how big the universe really is. I can barely handle what this video is telling me after it leaves our solar system.

Compared to that Pistol Star in the thumbnail you see there, our sun is about the size a flea's brain compared to a basketball. And they get way way bigger.

We have figured it out, in theory.
We need to bend the space/time fabric, by generating (or accessing and amplifying) an intense gravitational field. The more intense the gravitational field is, the greater the distortion of space/time, and the shorter the distance between 2 points.
But we are yet to be able to access gravity A wave (works at an atomic scale) using any matter found or synthesized here on Earth, but it doesnt mean that that necessary matter doesnt exist elsewhere in the Universe.

I'm totally on board with this and feel like long distance travel has to be related to this theory. I felt it to be a little much for some of the people in here with the opposite opinion of me on alien life. That shit is mind boggling even for us believers.

Humans are going to develop quite a few methods of high speed and long distance travel over the next few hundred/thousands of years (if we survive that long). But the ultimate high speed travel to other systems, galaxies, etc. will have to do with bending space time in my opinion. It will be cool as fuck to hop in our magnet thrusted anti-gravity whatever ships and pop on over to Mars in an hour though. Whenever the hell that happens.

is that a joke? we run shit in space

I'd be thrilled to live on a planet where cats are everywhere. And they're able to communicate with me.

But, our knowledge of habitable planets is next to nothing. It's like living at your house, or wherever you live, for your entire life and claiming because all you see is a cat, dog, and squirrels, no other animals can exist because you've never seen them.

Our knowledge of what is a habitable planet is limited to the planet we live on. As far as we know, a planet would have to be an exact copy of Earth with it's exact history. I'm not a religious person and I don't believe any God put us here.

People do tend to allow their bias to interfere with reality. People believe what they want to believe. Astronomers class planets as earth like but they have a pretty wide range of mass and size. I've seen planets from 1/2 to 2 times the mass or diameter referred to as Earth-size. This one is supposed to be very close diameter wise but they didn't know the mass yet. It is also in what they have determined to be the habitable zone of it's star but at the extreme outer portion of that zone. The star is about 1/2 the size and mass of the sun. We don't really know much about other stars because we aren't close enough to study them at the distance that planet orbits. The article says;

Kepler-186f orbits its star once every 130-days and receives one-third the energy from its star that Earth gets from the sun, placing it nearer the outer edge of the habitable zone. On the surface of Kepler-186f, the brightness of its star at high noon is only as bright as our sun appears to us about an hour before sunset.

Neil Degrasse Tyson was on Colbert last night and mentioned that Earth is an anomaly among the planets discovered so far.

I'd like to subscribe to the theory that, due to the sheer numbers, it's inevitable that there is life somewhere else but I can't convince myself yet.

I also don't buy into the infinite number of monkeys typing on an infinite number of typewriters being able to reproduce literary works. Mainly I doubt that monkeys would keep typing for very long.

Seems the modern version would be an infinite number of computers typing random letters.

You don't need to know if an event happen twice to ascertain odds. Where did you get that tidbit from?

Let's say you have a bag with 100 balls in it. You pull one out and it's red. What are the odds of the next one being red? You have no idea. Could be anything from 0% to 100% because you don't know how many red balls there are. You could have hit lucky and pulled out the only red ball, or they might all be red. But if you pull out 10 balls and 2 of them are red, you can start on estimating the probability for subsequent balls based on your sample of 10. One ball is not enough information to do that.

I think that's what he's getting at.

Maybe someone with better stats knowledge can poke some holes in this?

I think of a quote by drag racer Don Garlits after he broke a record for elapsed time in a 1/4 mile. He was asked what the ultimate record would be. His answer; "We can't get there before we leave".

As someone involved in racing, it has been difficult to accept an ultimate speed limit but I also know that speed requires power. Einstein expressed this as converting matter to energy. Finding a source of power to go that fast seems to be unlikely.

That's an excellent example. Even statistics don't always work out. I had a college statistics class with 77 other students. The instructor was giving us the example of birthdays. With 366 possible birthdays, in a group of 23 people there are 50/50 odds that two people will have the same birthday. With 78 people it's supposed to be 99.97% He wrote numbers 1 through 12 on the board and had each person write their birthday on a paper and pass it forward. He started writing them on the board under the month numbers.

In the first 23, he not only had 23 different birthdays but 23 different numbers. He kept going with no matches through all 78 birthdays. He said he would add his own and wasn't on the board either so no matches in 79 people. In 21 years of teaching statistics it was the first time nobody matched in the first 23 birthdays.

When you look at life developing, certain things have to happen and that's more like flipping a coin or throwing a dice and getting the same result every time.

You and anyone else hung up on the issue of distance and time should check out this video I linked earlier ITT. It discusses some theoretical alternatives to the standard propulsion systems of today, which makes the issue of distance and time seem a bit less daunting an obstacle for us to overcome.

But the fact it's happened once shows it's not 0% and you don't any more stats than that.

Not quite sure what you're saying. What's not 0%? The next ball, life or something else?

The chances of life occurring anywhere in the universe is not 0%.

I agree.

There has to be something out there we ain't the only ones

In my life time we won't find out

I believe what he's saying, is that in your analogy you know that red is possible by virtue of pulling a red ball. So you know that the next ball in that bag you pull from has the possibility to be red, but that's it. You have to pull more in order to see what other colors are possible.

So wherever a similar bag (planet) exists within the vastness of space, you could reasonably assume that it's possible for a similar ball to be pulled from it (or as it pertains to the thread topic, that life might be there).
