are we alone in this universe? if not why we havent found any living thing outside our planet?

Answer 1

No! The universe is endless.....there is defenently life out there somewhere.....maybe even another earth.....ya never know!

Answer 2

It could be because that we haven't really explored anything, except the moon, outside our planet. Human space travel is still only in it's infancy.. There are plans in the next 10 - 20 years to build a huge space telescope composed of seperate mirrors which will basically be the same as having a footbal field sized telescope that can detect other planets around other stars and tell what the atmosphere is composed of. researchers should be able to tell if there is life there by the composition of the gases in the planets atmosphere, and whether the planet is earth-like.
Also we haven't even begun to thoroughly explore Mars, Europa, and Titan, which are probably the best chances for life in our solar system.

Answer 3

I personally don't think we are alone. The universe is just too big to only have one planet that can support life. The reason that we have not found other life forms yet is that we don't have the technology to explore further than Mars. Their probably isn't life in our solar system but their has to be life in others. Theirs no reason to believe that other life has any better technology than we have so they have not been able to contact us either. I don't have any proof of this but it's just that the odds are against us being the only planted with life on it with an unlimited amount of space out their with an unlimited amount of other planets.

Answer 4

We are not alone in the universe. We have not found any living beings outside Earth because we have only explored this solar system with sattelites and humans have not even gone on another planet.

Answer 5

Throughout recorded history, science and religion has revealed an ultimate reality made up of 10 separate components. Quantum physicists, using Super-String Theory, believe the universe is made up of 10 or 11 dimensions. Their goal is to find the holy grail of physics - the so-called "Theory of Everything" - a theory that explains all phenomena of reality. Our solar system's 10 major spheres are physical representations of the 10 realms in the afterlife hierarchy of which the human body is a microcosm.

Answer 6

My theory is that there is another planet, in a different galaxy, that has an earth and a sun, and more planets just like our planets. For all we know, people (or aliens) could be living there wondering the same thing.

Answer 7

maybe bacause we have not explored very much outside of our planet. we have not had any manned missions to any planets (the moon is not a planet). it is a big would out there and for someone to think that we are the only "living thing" is very small minded.

Answer 8

Hi,

If they have found than they would say we are not...

They found some sort of tiny life on Mars I think. If they did found on some planet; there might be on others. I think 99% there are other life which does not mean always humans.

Answer 9

Our scientists are very good but they have not come to a stage where they are able to see further than what they are able to explore at this moment. As you may know some discoveries are many thousand light years away - so even if they had discovered some possibilities, it would be quite difficult for them to proof its authenticity.

Answer 10

Probably because either (1) Theyre too smart to have anything to do with us untill we get our collective heads out of our asses OR (2) We have had limited contact through the sighting of their craft and/or abductions OR both. Personaly, I dont believe were alone.

Answer 11

There are two reasons:

1. Either our technology is not advanced enough to receive the signals from other cultures in cosmos, or

2. Other cultures in Cosmos haven't reached the technology level high enough to create space travelling signal to let us know that they really are out there.
