1. The edge of the observable universe (relative to Earth) is 46.5 billion light-years away [1], not 5 million light years.

2. Humans have only observed a sliver of a fraction of that area.

3. Even if we can visually observe a planet it is almost impossible for us to determine what is on it.

I'm talking about the distance that we can determine the physical properties of planets. Given that we humans are not even close to being able to travel one light year, my point stands.

The fact that we humans cannot travel any significant distance in space means that for all practicle purposes, we are alone in the universe.
 
Ummmm....no. The universe is only 15 billion years old or so, and since we can't see further than the light carrying the picture, our radius of view is 15 billion light years.

Current interpretations of astronomical observations indicate that the age of the Universe is 13.73 ( ± 0.12) billion years,[1] and that the diameter of the observable Universe is at least 93 billion light years, or 8.80 × 1026 metres. (It may seem paradoxical that two galaxies can be separated by 93 billion light years in only 13 billion years, since special relativity states that matter cannot be accelerated to exceed the speed of light in a localized region of space-time. However, according to general relativity, space can expand with no intrinsic limit on its rate; thus, two galaxies can separate more quickly than the speed of light if the space between them grows.)

The word observable used in this sense does not depend on whether modern technology actually permits detection of radiation from an object in this region (or indeed on whether there is any radiation to detect). It simply indicates that it is possible in principle for light or other signals from the object to reach an observer on Earth. In practice, we can only see objects as far as the surface of last scattering, before which the universe was opaque to photons. However, it may be possible in the future to observe the still older neutrino background, or even more distant events via gravitational waves (which also move at the speed of light). Sometimes a distinction is made between the visible universe, which includes only signals emitted since the last scattering time, and the observable universe, which includes signals since the beginning of the cosmological expansion (the Big Bang in traditional cosmology, the end of the inflationary epoch in modern cosmology). The radius of the observable universe is about 2% larger than the radius of the visible universe by this definition.

...

The age of the universe is about 13.7 billion years, but due to the expansion of space we are now observing objects that are now considerably farther away than a static 13.7 billion light-years distance. The edge of the observable universe is now located about 46.5 billion light-years away.

Not really, our limitations only apply to us, not them..
I see no reason why we should be the only ones...But this we may never know...and I do believe in the power of man's imagination, but not true aliens....I reject all of the "ETs visiting us", and aliens in our midst.....conspiracy theories..
 
This depend if they are more intelligent then us. They will be our enemy.


Dirtpoorchris- Do you go around being hostile to every bird, dog, cat, and ant? Let me know when you are waging a war on pandas because they are dumber than us. I wish to join. And when we have conquered the species... I shall rule the pandas with an iron fist!


I think you are gone so let me argue for you.

Dirtpoorchris2- We may not conquer them in a war sense but we certainly pillage their resources for our own gain and affect them in the way they live.

Dirtpoorchris1- But for some reason I think aliens would have developed a deep sense of cultivation and have an evolved understanding of destruction and subjugation.
 
You found the product tag on the universe? I would think the universe would be infinite years old.
This I agree with; the universe has no size limit, no age limit...I do not think that time even applies, this is for our convenience here in our little corner..
There is more to this, which is far beyond our limited intelligence.

What does traveling have to do with anything? I'm talking about observing the universe.

I never stated otherwise. This whole conversation concerns the possibility of intelligent life elsewhere in the universe.

I see your point but not sede it.

The hurdles another oxygen breating intelligent being would have to get here from where ever there is - are the same. Virtually insurmountable. And we're not even getting into the time it would take.

Even if we could see a livible planet only one light year away, that's almost six trillion miles away. We haven't even sent a manned mission to mars which is only 35 million miles away.

I'm afraid too many people here have been watching way too much science fiction.

...and if you had read my posts, you would have seen that I said there could be other life, but in the distances that we can observe there is none, and that for all practical purposes we are alone.

The emboldened portion of your post is an assumption sans evidence.

Really?
Can you point to the scientific article that states we have observed life elsewhere or even an inhabitable planet? :shock:

No, can you point me towards the scientific article which states definitively there is no intelligent forms of life within our observable sphere of the universe?

Yes.

Every scientific observation so far.
 
Yes.

Have you seen a 4 leaf clover with your own eyes? Many have not if you have. I would think that if there was aliens they would be able to be almost as good as invisible to us. And if they could get to us chances are there technology would be good enough to stealthily asses us and never greet us even.

Well, that's fine if you want to go off into fantasy and wild speculation, I try to stick with science and logic.

You have absolutely no idea what you're talking about. There is no such article because no one is dumb enough to claim definitively that intelligent is nonexistent within our sphere of the observable universe. The correct answer is that we do not know.

If I showed you a large box would you be able to claim definitively that there wasn't a baseball inside it? No, you couldn't, because you do not know what's in the box, much the same as we do not know what resides within the vast, vast majority of the observable sphere of the universe.

Radiation didn't exist until 1865.

I apologize if reading comprehension is not your forte.
Again, I said "Every scientific observation so far."

I'll be as clear as I can:

As far as our telescopes can see, and as far as we can measure the levels of hydrogen, carbon, and oxygen on other planets and their distance from stars, there has not yet been an inhabitable planet as far as we can observe.

My original point to the OP stands, that is doesn't really matter if there are "aliens" out there somewhere in the universe. The distance for travel to or from is virtually insurmountable... for all purposes related to us in the next several hundred years, as a species it's best to assume we're alone on this tiny blue speck.

but for the 5 million or so light years that we can see in every direction, there are none.

It is wrong to make an assumption that this is fact...

We are going to send a probe on a nearby moon with ice covered water to see if there is life....WE DON'T KNOW YET and this is a VERY close neighbor.

Sorry, but we can measure hydrogen, carbon, and oxygen at very great distances.

Yes, we are sending a probe to earths moon to look for possible ice, but not to look for life.

Saturn? A planet like that could never sustain intelligent life forms, hopefully however, even some bacteria will be an absolute scientific breakthrough.

One of its MOONS....:confused:
