any more Earth's?
like earth, will the other planets makes organic evolution in the near future?

Evolution of living organisms is a process that occurs at a snail's pace in human terms. We would not see much in the way of results in the lifetimes of the people involved.johncena said:can we create artificial organic evolution in other planets?
Nukes wouldn't be the answer, you'd use a method that slow and gradual.Chaos' lil bro Order said:Just to pose an idea, would it ever be possible in theory to detonate several nukes on Mars to blow it into the goldilocks zone?

But the problem is that, Mars at that distance would perturb the Earth's orbit and the two orbit might not be stable.
We're fantasizing here, right? I mean, we're talking about moving worlds.Chaos' lil bro Order said:What kind of gradual force would you suggest?

This needs to be stated because PF has an "overly-speculative posts" policy.
Anyway, you'd do something like this:
Put a low impulse, long-running engine like an ion engine or VASIMR engine on an asteroid.
Use the engine to move the asteroid into Mars orbit.
Move the asteroid using the engine, Mars will follow.
Read up on "Gravity Tug".

There was a SciAm article on this a few years back. If we posit an unending universe, then it is easily calculable how far we'd have to go to find an identical Earth. It was a surprisingly short distance, something like 10^150 metres.Chaos' lil bro Order said:Secondly, by creating an Earth do you mean a particle for particle verbatim copy of the Earth? Then I would agree, even though I've not done the math, so its merely a gut instinct.

OK, that's a little bit farther...:tongue:qraal said:You missed an exponent. That was Max Tegmark's paper for SciAm and the minimum he quoted was 10^10^26 metres i.e. a double exponential.

Chaos' lil bro Order said:Well it sounds like a nice and fuzzy idea but I cringe when people do probabilistic calculations with data sets that are incomplete and admittedly inaccurate. Don't they have better things to do? :)
DaveC426913 said:It's not probabilistic. It's permutative. And it does set down some preconditions.
I think the only precondition is that the universe is homogenous and infinite in extent.
That being the case, there are only a finite number of ways that a volume of space can arrange itself.
If you have four types of egg (white, brown, double-yolk and speckled) and an infinite plane of eggcups, how many permutatons of the four eggs can you lay down before you run out of unique patterns and must start repeating?
Now, what if you have 10^60 eggs?
The answer is a pure mathematical derivation.
Of course. : clap clap clap : You should be very pleased with yourself.Chaos' lil bro Order said:The calculation is worthless imho, aside from making magazine covers.
I'm not sure why this is confusing you. Homogenous is pretty straightforward.Chaos' lil bro Order said:What do you mean by homogenous? As far as I know the Universe does not have a density that can be smoothed over to create an average density that would closely plot the actual density for all the regions of space. Not on a small scale (galaxy size) nor on the grandest scale (entire universe).
These "fringial regions", do you mean "at the edge of our observable universe"? Are you suggesting that, if we look at the same distance in every direction we will see a different makeup of he universe? Because if you do, the implication of that is that we are at the "centre" of something.Chaos' lil bro Order said:The fringial regions are dominated by massive quasars, whilst the inter-stellar regions are barren undense regions. You would never expect to find a planet in either of these regions, let alone an Earth like planet.
Obviousman strikes again. But you're making it sound like you're seeing with a clarity that no one else is.Chaos' lil bro Order said:I would pull any grant money researching such absurdities. This is not good physics or cosmology imho. Its an armchair calculation done to enshrine oneself into the legacy of being the man who told the world how long it would take before they saw themselves again.
Yes. With the postulate that the universe is infinite and homogenous, the conclusion is that there is an exact duplicate of you, and me, sitting in our very houses.Chaos' lil bro Order said:Also, did he consider the living beings on Earth? How long before I bump into an Earth where you and I are sitting where we are at this moment, etc.?
DaveC426913 said:Of course. : clap clap clap : You should be very pleased with yourself.
I'm not sure why this is confusing you. Homogenous is pretty straightforward.
In general, if we were able to examine a region of the universe an arbitrary distance from ourselves, it would on a large scale, be similar. Which means:

As for finding a planet in these regions, you are thinkng too small. Massive quasars and undense regions are small-scale deviations - blips - on the scale we're talking about.

It is no more a ridiculous conclusion as, for example, the MWI is as a valid interpretation of quantum mechanics.
Organic evolution is the process by which living organisms change and adapt to their environment over time. It involves genetic variation, natural selection, and genetic drift.
It is currently unknown if other planets are capable of organic evolution. So far, Earth is the only planet where we have evidence of life and organic evolution.
Organic evolution requires a few key conditions, including a source of energy, genetic material, and a stable environment. Water also appears to be a crucial component for the development and sustenance of life.
Based on our current understanding, it is unlikely that organic evolution can occur without the presence of water. Water is essential for biochemical reactions and serves as a solvent for many important molecules in living organisms.
Currently, there is no conclusive evidence of organic evolution on other planets. However, there have been some promising discoveries, such as the presence of organic molecules on Mars, that suggest the possibility of past or present life on other planets.
