Relativistic math is even more baffling than the vastness of space.

 

Due to time dilation, if my calculations are correct the 9 year there and back journey to Alpha Centauri at 99% the speed of light would mean that to an observer on Earth 63 years would have passed here. However, the effects of relativistic speed to the traveller, the slow down of time, and the contraction of space all change the equation. The rate of acceleration on the journey also changes things because you can not simply hit the gas and and be at 99% the speed of light without the G forces ripping the human body to shreds. Long space travel would require some sort of constant acceleration and deceleration in the 1 to 3G range. All of this further complicates the equations. I need more coffee before attempting this math...

 

 

Gunner11 is an alien:lol:

I didn't believe in Aliens until I got done reading some posts on here. Not so sure now!!!! I think some posters have been drinking some Alien punch with a hint of Grey Goose!!!:lol:

In my free time...

The odds are favorable there is advanced life forms in the universe simply due to the sheer size and numbers out there just makes sense there are more like earth out there.

 

Not necessarily.

 

Certainly the universe is enormous beyond our comprehension. But, that in itself proves nothing. You say the odds are too great that there are other life forms just because of the size of the universe, but nobody considers the odds of the actual formation of life of the formation of a planet capable of sustaining life.

 

Take earth, for example. Our planet is so finely tuned that slight variations of any number of variables makes life unsustainable. The tilt on its axis, distance from the sun, ratio of gases in the atmosphere, even the positions of the other planets in our solar system play a role in keeping earth where it has to be. So, to start with, there would have to be a planet to meet the criteria to support life.

 

Then you have to deal with the odds of life originating from random chance even when the planet can support it.

 

The odds are fairly low for both occurrences, a planet capable of supporting life, and life itself emerging by chance.

 

The fact that the earth and the universe are finite, the earth estimated at 4.5 billion years old and the universe around 15 billion years old, doesn't help.

 

You have every right to believe life exists elsewhere based on whatever is convincing to you. But, for me, the sheer size of the universe doesn't outweigh the sheer uniqueness of life itself. I do not believe life exists outside of earth...unless, of course, we send someone to space.

 

Of course, in a world of infinite possibilities, there's the possibility that a hypothetical life form elsewhere could require different criteria to exist than we do. I don't believe that, but it's a possibility.

You ask for evidence? Behold.......

 

Is that Mitch Albom?

 

His ears certainly make a strong case...

Not necessarily.

I always think that it's crazy to assume that life on other planets would need the necessary ingredients we need on earth. Isn't it possible that creatures from other planets could thrive in warmer or especially colder climates? I think that if life exist elsewhere there is a good chance that they do not need the perfect conditions that allow for life on earth. Perhaps they don't need water or maybe use a substitute for oxygen? I just don't see why we take an only humanistic approach to worlds and possible life that would most likely not resemble life as we know it now.

Certainly it's possible...and I'd assume they'd be like us, unable to survive in a different environment, so we wouldn't have to worry about them coming to earth for a hostile takeover.

Stephen Hawking seems to be a believer.

Just one more observation on the possibility of alien life, related to the Hawking's article.

 

If, as he says, earth is not unique and life has indeed evolved on other planets, it seems logical to me to conclude that they would be like us in one important sense. They would have evolved for their specific habitat. That would make it very difficult for them to move around and colonize space because a new home means an entirely new environment that would not support their life.

 

As I said, I'm not a believer, but if it is true, I have no fear of aliens devouring our resources and leaving earth a wasteland like Galactus from the Fantastic 4. This particular Hawking's work should be classified as fantasy, sci-fi, or comic book stuff, not science. It's all imaginative speculation, and not even original at that. How many movies, novels and comic books have delivered the same story that he proposes?

A movie i once saw summed it all up for me..., "If we are it, its an aweful waste of space up there"

The United States is about the only country who hasn't de classified their UFO files to the public yet. They have been hiding and covering up sighting for as long as they have been able to, but things are finally leaking out. England and Mexico (among other countries) have de classified their UFO files and a lot of that stuff is hard to just dismiss.

Having gotten to know Jim Schue and Adopted Admiral over the past several years, I am certain aliens do in fact exist, and do in fact live amongst us.
