A group for those interested in science from the vast expanse of the universe or technology.
I've been mystified recently about the nature of "significance". Is something significant because it's big, so the galactic scale is the most significant? Or because there's lots of them, so the subatomic level is the most significant? Or maybe it's complexity, so the workings of the brain are especially significant?
I love this quote, it puts things in scale- however, why precisely is something important? What is significance?
It depends on scale. At our scale, an Ant is insignificant. This is no so at an Ant's scale or point of view. Then again, we are insignificant compared to the planet we live on. Well, used to be, not anymore because we are having a global impact. So I think "significance" really has to do with the impact we make.
But the impact of a galaxy and the impact of an ant are ultimately more or less the same once we reach the end of the current universe, so over a scale of time (which opens another possibility: is the time something lasts what makes it significant?) they both cease to have any significance impact-wise.
Still think that the Universe was built for you xP ?
Something I'm really curious about is life in other planets, do the same laws of variation and natural selection apply to them? Do they look like humans or any other animal here on Earth? Do they breathe oxygen as we do? Are they anatomicly similar or the same as us?
I'm fairly certain that water creates all advanced life forms in the universe, it's a flexible substance, synthesis.
Water has a memory, it's been scientifically proven, perhaps that's why life is intelligent, there's also evolution aspect, our species has evolved greatly.
I suppose that life might exists on a planet that is in a habitable zone, our planet is lucky enough to be in that zone; perfect conditions for life to evolve. I think Mars was able to sustain life once, it may have been a lush, aquatic world, it still has polar ice caps. If our sun was smaller, it would emit less heat and it could allow Mercury to thrive, that planet has an iron core and ice Media.moddb.com it would have a magnetic field.
there is no such thing as a habitable zone in my OP (that is if you are referring to any sort of life that is not based on ours). If life wanted to propagate somewhere, it should have. BEcause we are carbon based life forms, water has significance to us. If the life forms were bAsed on other elements, water would not do anything or it would even kill them.
I am tired of hearing this idea that life needs carbon etc because it doesn't. OUR carbon-based backbone does but what if there were metaloxide based life or silicon based life? Our way life to another species or type could look like a death trap to them
In reality and theoretically, any planet in the entire solar system could have their own forms of life. E.g. life on jupiter could adapt as very low dense beings resistant to the vast gravity and radiation fluctuations etc.
We humans only understand life as we know it.We cannot assume that all life will rely on water and pretty little green grass because it won't. Maybe for carbon-based life forms but I am pretty damn certain that other beings exist in other forms not known to humans and undetectable as a result.
Scientists certainly want to find an advanced life form in other solar systems and galaxies, if it's a carbon-water structure or not, it still needs certain conditions in order to flourish, that's where the habitable zone comes into play. If you look for primitive life, you may find it on Jupiter's moons, Saturn's moons also harbor life. Yes, I'm pretty sure that some bewildering life forms exist, it's a vast universe after all.
yes. our habitable zone is not the same as organisms that need 1000 degrees C to survive or smth. And yes I am sure we can find intelligent life, but not in the way we expect it.
No, water doesn't have a memory. What you are talking about is Homeopathy, and that has been debunked long ago.
Of course. :)
