The theme of the website which you can enter below is actually the computer simulation of quantum mechanics, but you can also find a modest relativistic flight simulator. There are a couple of other programs on special relativity and also other programs on topics like the Van Allen belt. This relativistic flight simulator is available in two versions. There is a QBasic version to run in interpreted source code mode. The faster the computer, the smoother the action will be.
Compiled code runs faster than interpreted code.
This means that a QBasic program may be treated as if it were an applet, and JAVA programmers may be interested to see how this is done. If anyone wants to translate this relativistic flight simulator program into JAVA, perhaps with improvements, please let the author know and a hotlink will appear as appropriate. You won't be surprised to hear the opinion expressed that the worldwide distribution of a relativistic flight simulator ought to be a primary purpose of the Internet. The author has also produced a separate page of links to other people's relativistic flight simulators to underpin this opinion. Better relativistic flight simulators will be featured on the Gateway as they become available.
