First time poster, though I've watched the community for a good year or more now.

I am a hobby author/artist and am working on a fantasy genre world project that takes place on a different planet. One thing that I've always supported is the proper representation of (real) science in fiction. I understand the basics of how star type, planetary distance, rotation, and tectonics affect the environmental evolution of a planet. So far, I've been using this to design a world from the bottom up for this project. It has been fun, but also a little frustrating as so many years have passed since I last studied anything like this in detail.

What I would like to know is if there is any software out there that does a decent job at simulating this process? I'm not looking for something astronomically high end, though I don't mind paying for it if it does what I want it to do. (Read: I'm no longer a broke college student who is interested only in free web-based services, though they're always welcome!)

Specifically, I'm looking for something that can help me determine what an Earth-comparable planet would be like under slightly different circumstances, like slower rotation, or a different axial tilt. I'm also looking for something that can help me plot out how major land masses might develop through tectonic plate shifting - where mountains or seabeds will develop, where the trade winds will establish deserts or forests, how major wind or ocean currents will flow, where the greatest tectonic activity will be, and (maybe) how I can expect the land masses to look after significant amounts of time has passed, etc etc. (Star Wars single-climate planets need not apply!)

So far, I've found a couple helpful websites that address one aspect of this or another, but nothing that is very cohesive. If anyone can let me know about a service or a software that I'm not aware of, I'd really appreciate it. Thank you in advance!

Cosmos Stuff [13 Jan 2009|10:23pm]

The Science Channel has a Cosmos page with lots of info on Sagan's series, quizzes on how much you remember, an interview with Ann Druyan, a forum, etc... some cool stuff.

There's a slick flash applet but it didn't load in my Firefox for some reason. It did load in IE though. Could just be my install. *shrug*

"Why, in my world...
Cats and rabbits, would reside in fancy little houses,
and be dressed in shoes and hats and trousers.
In a world of my own.
All the flowers would have very extra special powers,
they would sit and talk to me for hours,
when I'm lonely in a world of my own.
There'd be new birds, lots of nice and friendly how-de-do birds,
everyone would have a dozen bluebirds,
within that world of my own.
I could listen to a babbling brook and hear a song,
that I could understand.
I keep wishing it could be that way,
because my world would be a wonderland.

Dinah: Meow! Meow! Meow!

Alice: Oh Dinah! Its just a rabbit with a waistcoat... and a watch!

White Rabbit: Oh my fur and whiskers! I'm late, I'm late I'm late!

Alice: Now this is curious! What could a rabbit possibly be late for? Please, sir!

White Rabbit: I'm late, I'm late, for a very important date! No time to say hello, goodbye! I'm late, I'm late, I'm late!

Alice: It must be awfully important, like a party or something! Mister Rabbit! Wait!

White Rabbit: No, no, no, no, no, no, no, I'm overdue. I'm really in a stew. No time to say goodbye, hello! I'm late, I'm late, I'm late! "

Surfer dude stuns physicists with theory of everything [15 Nov 2007|12:35pm]

calysto
A 39 year-old surfer from Hawaii says he has discovered the elusive "theory of everything" - a theory which weaves together the electromagnetic force, the strong force, the weak force, and even gravity... without string theory... and does so by using only four dimensions.

Further, the theory might make predictions which can be tested, something string theory does not currently do.

What makes this surfer's unlikely theory interesting is that some theoretical physicists are beginning to take note of it. [article]

homework help!! [09 Sep 2007|08:54pm]

snowflaksuicide
If the distance between the Earth and the Moon suddenly was multiplied by 1.6, by what multiplicative factor would the acceleration of the Moon due to the Earth's gravitational pull be changed? Use Newton's 2nd law and his law of gravity. Round your answer to one decimal place.

Space Science is in Trouble! [06 Jan 2007|05:49pm]

godtrip
Click here to sign a petition to George Bush to stop cutting space science programs!
Some of the program cuts and delays include:

Europa mission development is cancelled.

The Terrestrial Planet Finder (TPF) development is cancelled.

The Stratospheric Observatory for Infrared Astronomy (SOFIA) is
cancelled.

The Space Interferometry Mission (SIM) is delayed.

The Juno mission is stretched out and delayed.

NASA’s Mars program was cut 40% in the past year, despite the enormous
success of the Mars Exploration Rovers

The Age: Solar system just got bigger [17 Aug 2006|11:23am]

ilyat
Sorry, kids. You'll no longer have to memorise the names of just nine planets. Apparently, there will soon be 12.

A committee of the International Astronomical Union, which decides such matters, voted unanimously today to add three worlds to our solar system's planetary population. More planets will be added later, astronomers said.

Little Pluto, which had been in peril of losing its place among the planets, keeps its status, but only in a new category of "plutons," distant oddballs wandering outside Neptune in weirdly shaped orbits.

A Question [16 Jul 2006|06:55pm]

calysto
So, the theory is, that all elements other than Hydrogen and some Helium are created in stars. When a star is young it fuses Hydrogen, creating Helium... then as the star's death nears it begins fusing helium.... creating lithium, beryllium, etc... Then, when the star goes supernova, it scatters the elements it created into enormous clouds which form new solar systems from the atoms it created.

My question is this:

How can that theory explain oxygen? Wouldn't oxygen combust and burn the moment it's created inside of a star? How do oxygen atoms survive the inferno and subsequent explosion?

raise your hand if you love science!! WOOHOO!!

okay, so I am just in a good mood because the weather is fine today, and who says every post needs to be a squirming scientist asking a question?
This post is to celebrate the beautiful sun and our love for science!! wooooo!

Black holes are actually 'green' [25 Apr 2006|01:42pm]

ilyat
A new study finds that supermassive black holes, located at the heart of some galaxies, are the most fuel efficient engines in the universe.

"If you could make a car engine that was as efficient as one of these black holes, you could get about a billion miles out of a gallon of gas," said study team leader Steve Allen of the Kavli Institute for Particle Astrophysics and Cosmology at Stanford University.

"In anyone's book, that would be pretty green."

My website thisQuantumWorld.com has undergone a major overhaul.

Go to THE RULES and proceed to a discussion of two key experiments and their ontological implications (SCATTERING,TWO SLITS).

Or click on STABILITY and learn why the mathematical formalism of the fundamental theoretical framework of physics is a tool for assigning probabilities to measurement outcomes.

Find a SPACE for the quantum world.

Click on FORM to learn about the shapes of things.

Discover the TOP-DOWN structure of the quantum world.

Inform yourself about the measurement CONTROVERSY.

Know the meaning of objective PROBABILITY.

Recognize the PSEUDOPROBLEMS that make it so hard to beat sense into quantum mechanics.

Or be perplexed by BELL's theorem.

And come back soon for more...

Spinning Black Hole Leaves Dent in Space-Time [19 Mar 2006|12:33am]

webdiva
Using NASA's Rossi X-Ray Timing Explorer (XRTE), MIT astrophysicists have found a black hole that has chiseled a remarkably stable indentation in the fabric of space and time. The finding may help scientists measure a black hole's mass and how it spins, two long-sought measurements, by virtue of the extent of this indentation. (more)

The Cosmic Dance Of Distant Galaxies [18 Mar 2006|10:01pm]

webdiva
Studying several tens of distant galaxies, an international team of astronomers found that galaxies had the same amount of dark matter relative to stars 6 billion years ago as they have now. If confirmed, this suggests a much closer interplay between dark and normal matter than previously believed. (more)

A voice of reason [16 Mar 2006|05:24pm]

savyasachi
Misleading title, that. More like wisdom, I'd say.

No matter how many taunts were hurled on the WMAP team, I am glad that they kept at their job silently, and the result is that the three-year data, that was released at noon EST today, looks even more reasonable than their first-year data, at least at first sight. They successfully avoided astro-ph from being flooded by speculative string theorists by succumbing to demands of timely data release.

I like their diligence, and their imperviousness to taunts. I will allow the real experts to make further comments.

Has anyone of you ever heard something about Budda Machine and the way it relax you? What would happen if we combined Budda Machine`s sounds with 3D sacred symbols: flower of life, pyramid, metatron’s cube and etc.? You would get utility for meditation and relaxation - http://68.178.221.107/budda/budda.rsp. This is a simple utility for deep relaxation at home...and maybe for direct connection for cosmo?

My RSS Reader picked up this, which is a well-written and very readable review of the Big Bang, the evidence for it, and alternative models.

Well worth bookmarking I think.
