are we alone in the universe?

Answer 1

i dont think so.
im sure theres other solar systems asking the same exact question.

Answer 2

One of the most important scientific and philosophical questions for humanity is 'Is there life beyond Earth?' The recent realisation that life on Earth can survive under extreme conditions has rekindled thoughts that life might exist elsewhere in the solar system. It is only now, given advances in our theoretical, experimental and technological capabilities, we can begin to answer this question quantitatively, through the exploration of the Solar System and beyond.

Mars, although seemingly arid and lifeless now, shows evidence of having had surface water in the past and could still harbour moisture beneath its surface. ESA's Aurora programme will explore Mars the most accessible planet and the one most likely to have supported life at sometime in its history.

Slightly further afield, Saturn's largest moon, Titan, seems to have an atmosphere similar to that of the young Earth and so could replicate the conditions under which life originated here. The NASA/ESA Cassini-Huygens mission is studying the atmospheric chemistry of Titan.

Moving out from our own Solar System we need to discover how often do other planetary systems evolve with conditions that could sustain life. Beyond the solar system, over 100 planets around other stars have now been detected. ESA's GAIA space mission has the potential to detect and characterise thousands of new planetary systems.

Further into the future, facilities such as the proposed Infrared Space Interferometer 'Darwin' will be able to carry out spectroscopy of Earth-sized planets to look for indicators of life.

Answer 3

Probably not but! the many different things which came together to ensure life on Earth exists would seem to suggest it is not as common as we used to think.
Our distance from the Sun is just right for the temperature to sustain life and prevent our water from evaporating into space. the angle the Earth tilts at also helps here ensuring we don't get too hot or cold. The atmosphere is a perfect mix for organic life to breath. The moon not only controls the tides but ensures the Earth stays at the right angle as it orbits the Sun.
We have other life forms to keep our oxygen levels right.
Also we have the outer planets in just the right places to distract large comets, asteroids and meteorites from hitting us (although a few have got through) to name a few.
So maybe life or at least advanced life may not be so common.

Answer 4

The answer to your question is NO.
Think about the 100 million stars in our galaxy and the estimated 100 million visible galaxies and you mind starts to realize that we cannot be alone just on probability alone!

Its just we are not yet advanced enough to travel to other worlds beyond our solar system and explore them for life.

When we do...the question may become ..

"How many different forms of life are there?"

There is a mission planned by NASA to Europa (a moon) to explore below its frozen ocean...we may yet find life under that frozen ice on Europa !

Answer 5

No, just look at me, I'm a Martian (just kidding).

There are billions and billions of other stars out there. That would make it almost impossible for no other life to be out there. If we were alone in the Universe, that would be a lot of space wasted.

Answer 6

Just by the mere miracle of this world and all within it, it would be supremely unintelligent of us to think we are the only life in all the millions of universes there are. We are surrounded here by the unseen...such as guardian angels as well as fallen angels and other spirits...I'm quite convinced using logic that there are many diverse life producing planets with their own intriguing and I pray to God more peaceable and enlightened than we are! I also hope they stay away from the evil virus of a violent humanity...

Have a happy day!

Answer 7

No im convinced we are not alone.

The size of the Universe is so massive that there has got to be other life out there. We might not have found it yet (or so the government tells us) but its there....somewhere...

Bear in mind life has already been found on other planets, even though it was bacteria, its still life so that really answers the question. Yes there is.

Answer 8

We do not know and there appears to be every possibility that we will destroy ourselelves before we have advanced scientifically far enough, to find the answer.
You might be interested to read a book called "Chariots of the Gods" which suggests the "Gods" were visitors from space. Sorry can't give you the ISBN number (but Google may be able to) since my copy of the book appears to have "walked" - probably emigrated with family!

Answer 9

Somewhere there must be life, even if they aren't humans. Someone or something created the universe, i wouldn't of thought that it just...happened. Its like saying if a tree fell down in the middle of a forest and no-one was around to hear it, would it still of made a sound?!?

Keep thinking!

Answer 10

I very much doubt it. There's plenty of solar systems out there, and the odds of us being alone are phenomenenly low. (did I spell that right?)
I believe microbes were found on debris from Mars several years ago, so we may be disappointed to find the only other life is rather primitive, but then again who knows?

Answer 11

There is plenty of evidence to suggest the we are not alone in the universe.There are a huge number of solar systems in the whole spectrum of which we are a microscopic segment.There has to be some planets in many solar systems where intelligent living beings are there .....some may be like us some may be way ahead of us and there may be some who may not be two footed animals like us.
