COMPUTING LABORATORY
Modern physical and astronomical studies reveal that universe begin from a big explosion called "Big-Bang", and is now expanding. According some theories, the evolution of universe will conduce universe to a big collapse, where all matter will go to the same region.
Probably you previously read about what I wrote, and has the same question as me: how universe can collapse if it is expanding, and space is infinite? For many years I don't know the answer, since one day, when talking about that, comes this:
Imagine the space and you traveling to the boundaries of it (in Enterprise, please). As more far you is from any other body, more slowly your time is passing - this is one Relative Theory principle. If you are very far from other bodies, your advance in space is more slow than when you are close to other bodies. More far you are, and isolated, more slow you go. You never completely stop, because you have mass, too. But because don't exist straight lines in nature, sometime you will make a curve altering your course back, more or less from where you came - time is faster in back, and will make you approximate to universe areas where exist more bodies. And can make all bodies converge to a single point, again.
I am not sure about this answer. The most important thing is, it was not answered by somebody that is highly specialized about physics or related subjects. It need some logic, math, creativity, "spacial vision" and some other skills not directly related to the subject. That is for what this site is dedicated: experimentation, it has some results that can be an inspiration for more ideas. That can - during implementation - help people to be more disciplined, critical, patient, fun, creative, intuitive; in other words, more close for a natural human being.
Sometimes people makes thisquestion to me: how you can be ecologically correct using a computer (something that produce so many toxic waste)?
Applying the basic ideas: reduce use when possible (don't using to play stupid games, for example), reutilize - trying to buy reutilized hardware (you really need a top line computed for your work? Probably not.), recicling - finding the correct place to deliver your (very) old hardware.

Graphics under Linux -
part 1
introduce how to set graphics mode, manipulate
palette, set pixels, and make keyboard input on Linux console (use
SvgaLib).
Download it: grtut-1.tgz (8kb); install with $ tar zxvf grtut-1.tgz
Graphics
under Linux - part 2
how to use the X Window
System to produce graphics output on one window. Show: window open,
palette setting, frame buffer drawing, and keyboard input. Works on
more than 8 bit per pixel (BPP) modes emulating palette (uses XLib).
See in Linux ORG (link bellow) more recent projects related with
graphics under Linux, they are more specific solutions for each of
the visualization problems.
