is there life elswhere in the universe?

Answer 1

Most likely. The universe is so large, that chances are fairly good, that some form of life exists.

Answer 2

The universe is so vast that there are a huge number of options available for life to develop.

We used to think that life was somehow special, a unique process, but the more we learn about it the more we recognize that life is just one more natural process, as natural as fire or nuclear reactions. Get appropriate chemicals together under the right conditions and life is likely to be a result.

Therefore, with an enormously large number of opportunities for life to develop, it is likely that there is lots of it out there.

That's the good news. Now the bad news.

The distances to other places in the universe where life may exist are overwhelmingly large. The human species is unlikely to last long enough for humans to travel far from our own corner of the Milky Way Galaxy.

So while we can keep trying to communicate with possible intelligent life out there, it's likely that we will never make contact with any of them. Give up any thought of visiting them; the most we can do is listen for signals and send out our own signals which is like putting a message in a bottle and throwing it into the ocean.

Answer 3

According to the Drake equation that is used to determine a probability of life existing elsewhere:

The Drake equation states that:


where:

N is the number of civilizations in our galaxy with which we might expect to be able to communicate at any given time
and

R* is the rate of star formation in our galaxy
fp is the fraction of those stars that have planets
ne is average number of planets that can potentially support life per star that has planets
fl is the fraction of the above that actually go on to develop life
fi is the fraction of the above that actually go on to develop intelligent life
fc is the fraction of the above that are willing and able to communicate
L is the expected lifetime of such a civilization for the period that it can communicate across interstellar space.

[edit] Historical estimates of the parameters
Considerable disagreement on the values of most of these parameters exists, but the values used by Drake and his colleagues in 1961 were:

R* = 10/year (10 star formed per year)
fp = 0.5 (half of all stars formed will have planets)
ne = 2 (2 planets per star will be able to develop life)
fl = 1 (100% of the planets will develop life)
fi = 0.01 (1% of which will be intelligent life)
fc = 0.01 (1% of which will be able to communicate)
L = 10,000 years (which will last 10,000 years)
Drake's values give N = 10 × 0.5 × 2 × 1 × 0.01 × 0.01 × 10,000 = 10.


Therefore, it is probable that life has, does, and will exist elsewhere in the universe. It is just not probable that it is sentient or intelligent life as defined by human standards. I for one believe bactieria is probably prevalent throughout the universe in many places.

Answer 4

I believe there is. However, unless there is a way to get around Einsteinian physics, there can be no way for us to interact with that life--not in any meaningful way.

I know there are projects like SETI, but you have to assume that life evolved, not just life and that other intelligent life has evolved a psychology that will allow us to recognize their attempts to communicate as communications, let alone understand what they say.

Answer 5

With all of the planets and different large objects in the many, many galaxies it is very likely that other life has evolved. It may not look anything like us but it is possible that it could be intelligent, as well.

Answer 6

most likely. the universe is both a grand illusion and a great, endless stage.

the ultimate test of faith is belief in overcoming natural laws in order to tap the universe's vast resources and uncharted vistas.

pretty cool to think about when you're tired or high.

Answer 7

YES therse is life, earth is only one spcae where we are living. There is thousands of glaxies and worlds in this universe, but human knowledge is limited , so we still do not accept that truth.

Answer 8

Considering the odds and the vastness of the universe, it would be fairly egocentric to believe we alone possess it.

Answer 9

The rules of science make it seem likely, and I do not see any reason for Humanity to be God's only creation in such a huge and magnificent creation.

Answer 10

Of course there is life out there .To think different would be very small of us.Some day I hope that we will find out.I hope that i'm still around to see it.
