Solar System Similar to ours found

My As incorporate all the bull****, but I thought you didn't need the details, as it just makes it more wildly inaccurate. :snooty:

Skywalker, it is theoretically possible to communicate with superlumial tachyons, but thats way way off, iirc we dont know how to manipulate them yet.

Eh?

But , the guesses in my nonsense are split into smaller variables allowing fine tuning to produce slightly less random numbers than your method!

[reds4ever]

Any who

A2 does not equal fl x fi x fc x L


It is just a very crude approximation!

This is good news. At least we'll have something at which to point our new ground-based telescopes with adaptive optics.

The part that inspired hope of a terrestrial like planet was the configuration of the gas giant's orbit. It appears to be the first one found that has the circular orbit that would be needed for it to be possible that there would be interior planets. No guarantee's obviously, but it is the first hopeful opportunity. The Terrestrial planet finder mission is designed to detect these smaller, Earth ike, planets from Earth Orbit. They don't actually plan on sending a probe there. Also, with ion drive technology that has been proposed a generational colony ship could make the trip in about 300-400 years. If the international co-operation on space accelerates, we could probably build such a ship within the next hundred years IMHO.

The problem is it's twice Jupiter's mass. Mercury and Mars are in unstable orbits as a result of sun-Jupiter interactions, the asteroid belts aren't too happy looking places, and the earth's moon was created by a large body ejection which resulted in a glancing collision with earth.

A planet in a Jovian orbit around a star, but with twice the mass, would make it really hard for small planets to exist in stable orbits within the range of distances where life is most likely.

Twice as big AND nearer it's star, it's pretty much impossible that there is a habitable zone in that system.

On the plus side, at 90 LY away its only 'just down the road', covert it to parsecs and it sounds even closer! ;O) (Don't bother with Kilometers!)

Why don't we send our battleships there to break Jupiter II in half ?

A quick'n' dirty conversion tells it is a mere
851,472,000,000,000 km away. Down the road indeed

In astronomical terms I told you it looked better expressed in parsecs!

From what I've read from him, Elijah has an open mind about physics. Some probably would say too open.

How is that a problem if you have precalculated your travel, and if you use faster ways to get information than sight ?

N = R x fp x ne x fl x fi x fc x L

R is the rate at which stars have been born in the Milky Way per year, fp is the fraction of these stars that have solar systems of planets, ne is the average number of "Earthlike" planets (potentially suitable for life) in the typical solar system, fl is the fraction of those planets on which life actually forms, fi is the fraction of life-bearing planets where biological evolution produces an intelligent species, fc is the fraction of intelligent species that become capable of interstellar radio communication, and L is the average lifetime of a communicating civilization in years.

The problem with Drakes' equation is that we only have very vague values for most of the variables. As a result, N can be almost any number you want. Some estimate it at 1 or 2, others at thousands.

Personally, I think it is very likely that we are the only intelligent species in the universe.

[Whaleboy]

Skywalker, I used a more advanced version of Drakes equation to roughly calculate it, considering the distribution, and types of galaxies, size, longevity of each civilisation (had to make an educated guess), stars, orbits, as well as number of galaxies that are too close to produce stable stellar orbits ... etc etc.
