Is there life on other planets?

[HotelUser]

If there's a small possibility for something in space it's like 99.99% to be true somewhere.

There's hundreds of planets in our Galaxy alone, and then there's 125 billion Galaxies.

It's not crazy to believe in extra terrestrial life, it's crazy not to.

Yup, it is crazy not to believe in ET life.

We are not alone in my opinion.

As I said in a previous post, I am a scientist and that is the research I follow. So with that in mind, I use the Big Bang Theory to suggest just how possible it is for other life forms to exist.

Before the Big Bang, everything that exists, matter and energy consisted as a singularity. Basically that is a point of infinite density and an extremely high temperature. The singularity lived in the vacuum of space until one day it exploded. The explosion caused all the matter to move in different directions at very high speeds. At this point they were still extremely hot. However once the particles cooled they began to stick together. Cooling even more and becoming a controlled environment.

Now there is a lot more that I could explain, but I wont... but basically gas and matter formed to create the many suns, including ours. A cloud of particles spun around collecting other matter into its disc, and this is now called the solar nebula.

So, the particles stick together creating massive balls of mass, that we now call planets. Over the years they continually grew and fused together.

So the reason I mentioned that was to share with you how random the creation of the universe was. We are not here because we were always supposed to be... we are here because we grew, and our DNA make up came to survive with what the atmosphere provided. This process of evolution could have happened anywhere in the entire universe, they could have learnt to survive in their own particular way... perhaps they are sitting at home on their computers pondering the same questions...

This is actually quite a good topic!

I personally think their is something else out their. Why would we be the only ones ? It would seem a bit stupid. I have often thought about it. I think their may have been something out there thousands and thousands of years ago. However it still gets to me how their is no evidence.

[Conservative,]

Hmm, only problem with this debate is i don't think anybodies going to say that there's no other life out there.

Many scientists believe that life on earth actualy came from a different planet originaly, and apparently theres some evidense for this.

May I ask if you know why planet and what evidence?

[SirTezza]

Everything that we see is created from matter.

That matter was created via a the big bang which caused them to blast apart from singularity and inevitably join up and fuse together, creating the planets.

From there life began, and it started adapting to the atmosphere it was given. The same would have happened on other planets as well.

We are not here because we are unique, and earth is not special. The reason we have no strong evidence of other planets with life is simply that we don't have the technology to explore each galaxy.

We have only searched locally for life. With the vast vacuum of space, we don't have to be close to other life for it to be there.

I don't even think we should keep searching for alien life out there , there are like billions of galaxies , stars and satellites.
Plus scientists are finding those planets actually having oxygen or water in them! That's like senseless.
It is called "Alien Life" for a reason...

There has to be life on other planets. Think of the hundreds of millions of galaxies nearly identical to ours, there must also be planets similar to ours that have the ability to host life. I would say it's almost a certainty that there is life on other planets.

[SirTezza]

Yeh I agree that there is probably life identical to ours on some of the planets, judging by how many there are. But people often forget that even if they don't find planets with the same atmospheric conditions as Earth, it doesn't mean there isn't life there... it is just simply life that is supported by different components.

Scientists are beginning to open their research onto looking at other means of supporting a different kind of life system. This is the time when they start to get somewhere!

Imagine the Earth as a grain of sand - now *attempt* to imagine how many grains of sand are knocking about.

That is the Earth compared to the size of the Universe in the best terms we humans can put it, however I would certainly not go looking for alien life.

[SirTezza]

I have always said that alien races will be similar in the way they act. For example, there will be good and bad aliens. People on Earth assume they will be the latter without a thought. That is unfortunate, because in my opinion aliens have been saving us from self destruction for many years.

Different doesn't mean bad.

I for one hope for contact.
