are we alone in this universe?

Answer 1

Well, lets look at it this way.

Light travels at a speed of 180 thousand miles per second... It takes 26 light years to get from 1 side of the galaxy to the other. That means, that our galaxy is approximately 147,588,480,000,000 miles wide.

There are BILLIONS of stars just like our own in this galaxy alone, plus, the millions of billions of other galaxy's that exist beyond our's.

The closest star, Vega is considered to be around 26 light years away, that travels along the outer core of another galaxy 2 light years away from our own.

Fortunately they think the universe is expanding, because if it were shrinking, our galaxies would collide.

In, mid Feb. 2004, an international team of astronomers may have set a new record in discovering what is the most distant known galaxy in the universe....It's located an estimated 13 billion light-years away, the object is being viewed at a time only 750 million years after what they say is the big bang, when the Universe was barely 5 percent of its current age.

If you can imagine... 13 billion light years away is approximately, 73,794,240,000,000,000,000,000 miles away...

I dunno even know what that number is... I suppose nearly 73,794 billion billion miles away...

Take note: The moon, Titan-- One of Saturns moons, is located 900,000,000 miles from the Sun. We are approximately 100 million miles from the sun.

Mars, is around there too, at 98 million miles from us.

All that space-- all those galaxies, all those stars, planets...what's the chance's that we're the only ones?

No, I don't think we're the only ones. It's certainly not impossible-- simply improbible.

Answer 2

You are not alone, b'cos i am from mars :)

Just kidding, i think the "universe" is too huge compared to earth

and the "universe" as we know is 15 billion years old and the "life on earth" is just a few million years old, so to speak we are just a speck w.r.t time as well as space.

If at all we are alone, that would be the "mother of all coincidences" thing ever in the universe.

Answer 3

Most probably, almost certainly, there are life forms, may or may not be similar to ours, elsewhere in the universe.
Our sun is one among many billions of similar stars, and planets circling some of these stars have already been found. Formation and evolution of life forms in such planets is a distinct possibility and there is no known reason to think otherwise.
We in my opinion are not alone in the universe.

Answer 4

No. There are many earth-like planets out there (30 billion).

"There are about 300 billion stars in our galaxy. About 10 percent (or 30 billion) are roughly Sun-like," he explained. "At least 5 percent (1.5 billion) but possibly as many as 90 percent or 100 percent (about 30 billion) of these have Jupiter-like planets."

Much of the evolution of our own solar system, including the formation of Earth, was orchestrated or affected by Jupiter, the largest planet which is by far the bulk of the solar system's mass, excepting the Sun, of course.

What about Earths?

The calculations, which are part of a paper that has been submitted to the journal Astrobiology, don't bear directly on worlds like our own. But with what's known of planet formation, some speculation is possible.

"A reasonable guess is the same number of Earths as Jupiters."

Answer 5

Yes we (human) are the only one here on this planet. Only on planet earth live lives. There are no more living things in the universe. The bible tells us that. We are made to live forever we have the personality of Jehovah God. Like Love, Wisdom, Justice and Power.

There is no UFO or other things. UFO is made by man to make people scared and to hold us down.

Answer 6

on the 2nd we've unquestionably 0 information different than for one place that life can exist. That one place is here in the international. so as that supplies us desire that it may take place else the place, we basically could discover it or greater importantly discover information. i like to think of we are no longer on my own however the way life started in the international i'm susceptible to think of life is uncommon, a minimum of as far as we've stepped forward. The universe is a foul place and we've had various mass extinction's that brought about us evolving, that throws some uncertainties into the equation. speaking of equations, the Drake equation that could get a point out is a tad ambiguous and that i think of unsuitable.

Answer 7

According to the super string theory, the probability of finding an extra terrestrial life in this universe is high.

Answer 8

No.
I dont believe so.
I'm not saying the "little grey men" are on the way,I just try to keep an open mind about what I cant disprove.
Besides, everyone knows the "greys"got sidetracked at the Hooters on Metabelis 3.

Answer 9

I don't think so. Its a waste to create such a huge universe just for those on earth.

Answer 10

No, how arrogant to even think we are the Universes only creation.
