Universe Sandbox 2 is Coming
Jan 10th
I’m pleased to announce that the next version of Universe Sandbox will be released in early 2010.
There’s so many new features and improvements to share; I’m so excited. My primary goal with the new version is to make it easier to use and learn while exposing many of the buried features (like chart mode) in the original version.
As we approach the launch date I’ll be posting here about the new features and improvements. Be sure to subscribe.
Here’s two work-in-progress screenshots from the new version. There’s still more to do and some of this will change before it’s released.
You can read more about the next version in the forums:

Newton’s Birthday
Jan 4th
Today’s Issac Newton’s birthday, the man who discovered the simple equations that predict the forces of gravity.
This simple equation is at the heart of Universe Sandbox. It’s what makes it all work.
And while his beautiful equation doesn’t work when you get really small or really big, it’s “adequate over an enormous range of masses of objects from about 10−23 to 1030 kg.” source
It’s amazing how something so simple can explain so much.
Happy Birthday Issac.
.
For comparison: Earth’s mass about 6 × 1024 and the Sun’s mass is about 2 ×1030 .
