Odds of other life in the Universe (Page 4)
kittybobo34: Although its possible there is something we haven't seen yet. Life is so complicated, not sure how it could duplicate without starting at the same place. The beginnings of life at the deep ocean vents show that the simplest life is RNA based and uses sulfur as fuel.
lgs1013: My earlier point was that intelligent life could exist on infinite plains of existence not limited to our perception.
lisa99hunter: Yeah I saw a program “the origins of time. Intresting topics around quantum physics with 3b dimensions of time and experiments done in CERN where curtain particles appear two different places at the same time and it appear as they exceed the speed of light but they don’t simply inn an other dimension of time simultaneously
lisa99hunter: Very much three demotions of time that you can co existing in have a dialogue with someone in the future relative to you and that person conversation with you will happen in the past relative to her. Simultaneously. Such predictions says we don’t have to be on a linear time line. We know well that both your speed relative to a more stationary person your time will significantly slow down. Same with gravity. Less gravity relative to someone with more gravitational force your time slows down. Classic time dilation. There is something called the “twinn paradox “ intresting stuff. Einstein says the faster you go the slower your prescription of time will be relative to a more stationary person and time will stop at speed of light for that person who experienced this again relative to a more stationary person. Now with experiments done with a particle called fermions there are three different ones. We don’t know really of they have mass or not they seems to change and at one experiment at CERN the speed of light was exeded. Which we know is wrong specifically a particle with mass. A fermon arrived not long after its departure and you had two of the same particle one in the past one in the future at the same moment. Which indicates that time in fact have more dimensions that can co exist
lgs1013: Time appears linear from our dimensional perspective. Think of it like standing stationary by a railroad track as a train passes. We see the train appear, pass us, then fade away. Now imagine seeing that same train, but from the perspective of observing it high in a hot air balloon.
kittybobo34: But, back to the subject, I think the odds are high for life in the universe besides ourselves.
kittybobo34: We are finding lots of planets in the sweet zone for water, most of them a little bigger than ours, but intelligent life requires a long stable period for evolution to progress to complex life forms.
kittybobo34: If we can ever get out of this solar system, there is a bonanza of earth like worlds out there.
kittybobo34: Thinking about that, it would mean that ice worlds with vulcanism would be the most likely to harbor primitive life.
kittybobo34: Not many people know that this planet was ice from pole to pole for a while in the first billion years.
LiptonCambell: I think my previous comments still stands. The 'odds' are not good, because we know too little to form the odds.
The conclusion that the odds are good arent based on any observation, but crass assumptions that actually contradict our observations.
kittybobo34: If you have been keeping up with the news, you would know that an early version of life was found in the deep sea vents. Uses RNA instead of DNA to propagate., and what's coming out of those vents is a soup of organic molecules, and nutrients.
Also we are up to a 1000 planets discovered as well as ones in the Goldilocks zone for water. Since the only planet we know of in that zone has life, there is a 100% proboblity the others will too.
Blackshoes: The research doesn't state RNA does anything of the sort '. It 's just another unproven assumption .
"The scientists found that not only was the chemical composition of the chimneys important when it came to forming RNA, but the physical structure of the chimneys was key too. When the researchers mixed iron, sulfur and silicon solutions into their simulated oceans, instead of slowly injecting them into the seawater to form chimneys, the resulting blend could not trigger RNA formation."
kittybobo34: Never the less they found that type of life there. Another step toward figuring it all out. Single cell RNA based bacteria life, combined in a symbiosis with another, would give us that first Cell with a nucleus and mitochondria. After eons of that, the step toward sex made it possible for life to evolve rapidly, giving us the Cambrian explosion where life started evolving in all directions.
kittybobo34: An error in your thinking Mr. Black. Horseshoe crabs have evolved many branches, the one we are all familiar with is so well adapted to its environnment that it has remained static. Same with sharks, the basic line is still there but there are tons of other branches like the whale shark or the hammerhead.
