Interesting science opinions?

Question

Well science says that there are many galaxies, dimensions even? well now why some eliminate the theory of extraterestrial? as there are many galaxies and even on Mars (or on another planet don`t know wich exactly) they found frozen water, so water means life sure it will take thousands of years maybe more but even so... in another solar-sistem maybe there is life, more advanced or inferior? who knows as we canot travel faster and takes so much that even in a life we can`t reach other solar-sistems... so how can we do that?

I do not think aliens do exist, but who knows?!

People are narrow, sure I do not believe in Aliens, Time Travel. But I am interested in them if I want to write good stories.. but I guess people like you... (not all here) are so narrow they hate culture, oh well not all people are smart.

Answer 1

When did the theory of extraterrestrial get eliminated?
I never got the memo.

A theory is only a tool. By definition, a theory is not "true" nor "false".

A theory is useful or it is not useful.

For example, Isaac Newton came up with a theory to predict the attractive force due to gravity, between any two objects with mass. In cases involving very high energy levels (including very high speeds), Einstein's gravitational theory is more useful -- it makes more accurate prediction.

Does that mean we toss Newton's? Of course not. In our everyday life, it is very rare that conditions will make Newton's theory give wrong answers. For example, I know the mass of my car. I know the torque delivered by the engine to the rear tires, therefore I know the force with which the tires will push on the road.

F = ma

I already know F (force of the push by the tires) and m (mass of car), I can easily find a (acceleration: 0-60 mph in 8.5 seconds).

I could have used Einstein's theory, with a much more complicated calculation. I probably would have found that it actually takes one billionth of a second more than what I found with Newton's. Do I care? So Newton's theory is still useful.

You say some have eliminated the theory of extraterrestrials. You must tell us "with respect to what". For example, it was used to try and explain crop circles in the United Kingdom. Then, one day, the guy who made the crop circles admitted they were fake (he and a buddy would go out at night to make crop circles). In that case, the theory of extraterrestrials was no longer useful.

At the other end of possibilities: if the universe is infinite, then anything that is not explicitly forbidden by nature must happen somewhere. Since life is (obviously) possible in this universe, then in an infinite universe, there must be life somewhere else. The problem is trying to determine if there is life close enough to us so that we will find it (or them), one day.

Careful about counter-implications:

Life (as we know it) needs water. However, water does not automatically mean life is present. It is very easy to think of conditions under which you could have lots of water, and no life.

Answer 2

Well good scientists would not eliminate the possibility of extraterestrials unless they had proof. Some people might rule them out if it conflicts with their religion but then that is separate from science.

I'm not convinced that the presence of water prooves the existance of life but it certainly is compelling evidence. Maybe others know better than me.

As for inter-solar travel I have heard of two possibilities: either a very small craft which moves incredibly fast or a very large craft which moves slowly and carries a (self sustained?) colony. I think both options would require lots of time and effort and more than a few scientific breakthroughs. Still its nice to dream.

Answer 3

I think its a little self-centered and naive to think that we are the only ones in the entire universe. There are thousands of other solar systems with their own suns and planets and there must be life on some of them. I know that we think we know that there is no life on any of the planets on our solar system but that is based on what we know about the conditions that we can live in. How do we know that there aren't organisms that can exist under conditions that are detrimental to us? There could be underground societies on Mars that we have not been able to get close enough to the planet to get to. Is that probable? Maybe not, but to completely discount any idea without difinitive proof is not scientific. Besides, imagine the possibilities. When I was younger (I'm not too much into that now) I watched Star Trek with my dad and always hoped I could one day be a Star Fleet officer, now I hope that maybe my kids could, with the humongous strides that technology makes everyday, you never know, it could be possible.

Answer 4

From a purely statistical stand point there are billions of stars, and if only a few on those have solar systems and only a small portion of those have planets that could support life that still leaves millions of possibilities of life on other planets, that life could be an advanced race or maybe a couple of single cell organisms.

So I tend to believe it is highly probably that life exists somewhere else in the universe, but I'm not waiting for a space ship to land and someone human looking to jump out and say "howdy".

Answer 5

All things are possible under the sun - any sun, any galaxy, any universe or dimension. Believe what you want - no one can prove it one way or the other unless the Vulcans really do show up and help us with a warp engine... just kidding. I really do believe its possible, even likely that there is life out there somewhere. Maybe someday we'll get to find out for sure. I kind of hope so.

Answer 6

Of course life exists elsewhere in the universe, but there is no way to verify it for certain. Even if we had a tecnology to take us to distant solar systems we would most likely crash into dark matter along the way. Contact would be lost with the spaceship with no way for us to know why it happened. It's really pointless to consider travelling to other solar systems, anyway. Life support for that amount of time would be impossible, even sending humans to Mars is an ill-conceived notion. A manned mission to Mars would be a one-way trip. There is no way to send enough fuel to power a spaceship enough to escape Martian gravity. Even putting a permanent base on the Moon would be so expensive it would bankrupt our economy, and enslave our entire population to support a few Military operatives in an uninhabitable environment. What those programs really do for us is to employ thousands of engineers and scientists on impossible projects, to the benefit of aerospace corporations that work with the military, instead of using the same resources to solve the problem of finding new energy sources for the people who are paying the bills.

Answer 7

There is not much we can do, SETI is going all out trying to make contact but the chances are remote that anyone will be found. I agree that here must be plenty of life elsewhere, it would be fantastic to meet someone from another system.

Answer 8

I'll have a word with my mate General Jack O'Neill - see if I can arrange a get together for a trip thru the Stargate.

Seriously though, we haven't a hope of getting there in your, mine or our great great great great great grandkids lifetimes. They need to find a way to travel at many times faster than LIGHT SPEED - hyper space if it exists.

Answer 9

they have already found evidence of life on mars. such as fossilised bacteria the pyramids and the face. see this web sites;
http://en.wikipedia.org/wiki/Face_on_Mars#The_Face_on_Mars
http://www.thehiddenrecords.com/mars.htm

also if you look at the stats there are billions of stars in our gallaxie and billions of gallaxies, so trillons of places for life to start hence life must exist

Carl Sagan on Universe at Youtube.
(He's not an alien, but he can explain about extra terrestial life on other planets.)
