UFOs' in mexico

[Razore]

No. We arent alone in our galaxy. How the hell do you know there isnt another galaxy out there with a planet like Earth called WOOT?

[UnderGod]

Untill we build starships with a transwarp drive and create an empire in space and fight the borg and.. and... and..

There still is a possibility..

Did you even read my post or just the last sentence?

[Razore]

Sorry. I meant "Arent"

[Silvanoshei]

I know what you meant.

I love you, man.
Just because it's impossible to find ET NOW doesnt mean that it wont be possible LATER. As you know, computer processing power doubles every 18 months, making it possible to search more at one time. Just because Alpha Cent. is 4.5 lightyears away doesnt mean that ET doesnt exist. In our galaxy alone, there is a cluster of multi-billions of stars. Our galaxy is part of a small globular cluster filled with hundreds of other galaxies, and our cluster is part of a bigger cluster of clusters, and then the ever-expanding universe. Thats more stars that you could ever hope to count. In all of those stars, how can you say that only one was suitable to host a planet containing the ONLY sentient life-forms?

Dont forget, we did have 900 years of scientific regressing during the Midieval Period......

Considering that the second closest star to us is Alpha Centauri, which is four and a half light years away, there is no way that we could ever reach "aliens", and the chances of them ever reaching us are infintesimal.

A working knowledge of biology and geographys tells me that the chances of sentient extra-terrestrials even existing are extremely small. A working knowledge of astronomy tells me that the chances of finding such life-forms are even less. A working knowledge of physics tells me that the chances of any sort of communication or meeting would be impossible.

We are alone in the universe.

This relies completely on the assumption that we are the most technologically and mentally advanced species in the universe.  Because that light is so damn far away, there may be some other system farther than Alpha C. that may have what we have all ready.  There is no way to proove or disproove it.

Of course you pointed out it was your belief in the beginning, so your case rests with you.

I would still say that because there are systems in our universe that are older than our own that it is only logical to theorise that there is a greater chance for a civilization such as our to allready be in existance at a place farther from the center of the universe (or galaxy) than we are, and thus has had more time to develope than us.  The speed at which light moves prevents us from seeing such things for a very long time, so unless the other theoretical civ's make a faster-than-light speed mode of transportation it would be very very difficult for us to be seeing them at this point in our history, considering the rate of the galaxy/univers expansion and the speed of light.



On a side note I have looked up in the sky and seen silver spheres on more than a few occasions.  Both in formations and not, in the same place for hours of time.  It has been years since that has happened.  It has also been years since my eyes could focus as well as they could then as well.  The computer screenhas taken its toll, and the lack of sleep probably messed them up as well.  The existance of silver spheres does not lend itself to "exra terrestrial life" or to "military experiment" but I cannot think of an explaination myself.  All I know is what I saw, how it behaved, and how many there were each time (3 each time.)

Peace.

Just because Alpha Cent. is 4.5 lightyears away

4.35 light years away, i'm not picking, but the speed of light is 186,000 miles per second you were 0.15 years wrong. That is a LOT of distance considering 1 lightyear is 5,900,000,000,000 miles.  I have heard talk of people trying to go the speed of light, using a HUGE "parashoot", it would me made of an ultra light fabric and would deploy in space.  It would take a year to speed up, what makes it fast is the LIGHT bouncing off it, actually pushing this ship though space gaining speed all the time, thats just one idea, humans have not made anything space dinamic enought to travel that speed in a straight line.

[Newbie]

Maybe that's why the UFOs are light and silvery in appearance, maybe they use that technique of travel, light bouncing off and speeding them up.

[WolfTones]

I believe that there is life out there, But i also believe that they are millions more years advanced than us,  They are looking BEYOND light years but thats just too slow, considering that the end of the space is estimated to be about 85 BILLION light years away and expanding.

Oops, I must have stumbled onto the wrong message board. Where I'm from, PCRPG, intelligent conversations don't exist.  

Just because it's impossible to find ET NOW doesnt mean that it wont be possible LATER. As you know, computer processing power doubles every 18 months, making it possible to search more at one time.

Microprocessor speed increases as a result of an increase in microtechnology ventures by large corporations. So unless you're referring to SETI, this point is kind of moot, since the bottleneck lies in collecting data, not processing it.

Just because Alpha Cent. is 4.5 lightyears away doesnt mean that ET doesnt exist.

I wasn't using distance as a argument against the existence. I was using distance as a argument against possible location and communication.

In our galaxy alone, there is a cluster of multi-billions of stars. Our galaxy is part of a small globular cluster filled with hundreds of other galaxies, and our cluster is part of a bigger cluster of clusters, and then the ever-expanding universe. Thats more stars that you could ever hope to count. In all of those stars, how can you say that only one was suitable to host a planet containing the ONLY sentient life-forms?

Here we go. Earth is an unbelievably rare combination of unbelievably rare things. Allow me to introduce you to the four conditions a planet must have for sustaining any kind of life at all.

- a constant and relatively mild temperature
- an abundance of water
- a sufficient quantity of the gases, such as oxygen, nitrogen, and carbon dioxide, necessary to sustain life
- an atmosphere of sufficient thickness to protect living things from a star's ultraviolet radiation

There four conditions exist in such a perfectly balanced and intricate combination that it's basically impossible to be duplicated an any planet either here or in a billion light-year radius of us. Earth hangs the perfect distance away from a small star, with a perfect axis and period of rotation with the perfect amount of necessary gases in the perfect atmosphere. Earth has the perfect mass for the gravitational field to hold gases in the aforementioned perfect atmosphere. Earth's perfect magnetic field protects us from cosmic radiation and foreign particles. You may think I'm overstressing the fragility and perfection of our planet, but I haven't even scratched the surface. If you had any idea how tentative and ridiculous even our own existence is, you'd know that any chance of duplication, even with billions of planets, is next to nothing.

Keep in mind: that whole spiel was about life in general. Those are the odds of even the most basic prokaryotic organism existing elsewhere. The idea of evolved, sentient creatures like ourselves is basically laughable and ludicrous.

Dont forget, we did have 900 years of scientific regressing during the Midieval Period......

Nine hundred years is the downstroke of a blink of an eye. Nine hundred years is a nanosecond.

The speed at which light moves prevents us from seeing such things for a very long time, so unless the other theoretical civ's make a faster-than-light speed mode of transportation it would be very very difficult for us to be seeing them at this point in our history, considering the rate of the galaxy/univers expansion and the speed of light.

It is absolutely impossible for anything to travel faster than the speed of light. Period. Not unlikely; totally against and contradictory to the laws of physics.

I have heard talk of people trying to go the speed of light, using a HUGE "parashoot", it would me made of an ultra light fabric and would deploy in space. It would take a year to speed up, what makes it fast is the LIGHT bouncing off it, actually pushing this ship though space gaining speed all the time, thats just one idea, humans have not made anything space dinamic enought to travel that speed in a straight line.

Photons do not have mass, so they can't push anything; be it an atom or a starship.

considering that the end of the space is estimated to be about 85 BILLION light years away and expanding.

I hope that by "estimate" you mean a wild guess, since there's no way anyone could have any possible idea as to the size of our universe.

A Photon does have a mass because Mass = Energy and therefore Energy = Mass.  The exact value has never been found, but many people have tried to find it's value and came out around 7 x 10-17 eV.

A Russian scientist solved an equation which gives you the exact size of the universe.

You mean life as we know it here on Earth, right?

It is absolutely impossible for anything to travel faster than the speed of light. Period. Not unlikely; totally against and contradictory to the laws of physics.

The laws of physics were created here on this planet and in this solar system. There is no way of knowing what is and isn't possible outside here yet.

If light can be pulled by gravity, it has mass. Look at black holes for example.. The gravity is so powerful that it can pull light into it. If you want to go back to physics.. If something can be pulled, it can also push.

This arguement really is pointless though, because what the human mind can't comprehend it doesn't want to believe.

An effectively inert photon has mass, yes. (Actually, it really doesn't. It would be more accurate to say that a repeatedly bouncing photon would add to the mass of the container it is in, which is not the same. This subject is tricky, however, and totally irrelevant anyway.) But when the photon is moving in a beam of light, per se, as in hitting a starship, it has zero mass.

A Russian scientist solved an equation which gives you the exact size of the universe.

I think you may have confused this with the size of our observable universe, which is about 13+ billion light-years. This is simply found by multiplying the speed of light by the time since the "big bang". We have no way of knowing, however, what exists beyond that or how big it is, since the light emitting from that territory is still travelling.

A Photon at rest has energy, and therefore has mass.  A moving Photon has energy as well... and therefore also has a mass of it's own.

[edit]
The mass may be so small that it is regarded as insignificant.... but it still has mass.
