In cosmology, dark energy is a hypothetical form of energy which
permeates all of space and has strong negative pressure. According to
the theory of relativity, the effect of such a negative pressure is
qualitatively similar to a force acting in opposition to gravity at
large scales. Invoking such an effect is currently the most popular
method for explaining recent observations that the universe appears to
be expanding at an accelerating rate, as well as accounting for a
significant portion of the missing mass in the universe.

Two proposed forms for dark energy are the cosmological constant, a
constant energy density filling space homogeneously, and quintessence,
a dynamic field whose energy density can vary in time and space.
Distinguishing between the alternatives requires high-precision
measurements of the expansion of the universe to understand how the
speed of the expansion changes over time. The rate of expansion is
parameterized by the cosmological equation of state. Measuring the
equation of state of dark energy is one of the biggest efforts in
observational cosmology today.

Adding a cosmological constant to the standard theory of cosmology
(i.e. the FLRW metric) has led to a model for cosmology known as the
Lambda-CDM model. This model agrees closely with established
cosmological observations.

As NASA reports indicate, 70 percent or more of the universe consists
of dark energy, about which we know next to nothing.

At the beginning of March, 2006 the satellite of China National Space
Administration, DARKSTAR started operations, observing in neutrino the
solar corona.

It results a sensational information that our system also contains
dark energy. This substance is located within the solar surface.

We have placed above cosmological information into our screensaver and you
can view allocation of dark matter in our Solar system!

ZSync is a multifunctional folder synchronizer. Because of its universal approach, it's equally great for synchronizing with laptop, backing up data, publishing web site over the FTP, updating AV databases, synchronizing with remote computer, finding differences between two folders, and much more.

Unlike other synchronizers that merely compare which of two files is newer, ZSync is able to remember the synchronization state and track changes in each folder individually. Thus, the program appears to be more accurate; it detects suspicious changes and prevents conflicts (when the same file changes in two locations.)

The program is easy and convenient to operate. Just a glance at the screen is enough to instantly see the overall status, what has changed, how serious the problem is, and what action is suggested. Gravity levels (changed, suspicious, conflict, etc.) are marked with color. File and folder state is marked with easy-to-read labels, and where some actions are required - the program displays corresponding buttons. If certain files or folders should not be synchronized - just drag them to the "off" category.

ZSync's power is best demonstrated during synchronization with a remote computer (e.g., home and office computers.) Any data transmission channels are good for this: e-mail, flash memory, even the regular floppies. The unavoidable blunders (could not deliver the message, unable to read the disk, etc.) do not cause errors; they only have ZSync try a bit harder and take the necessary steps to ensure your work result's safety.

Arrange many-colored balls into combos in the shade of the lofty pagoda in this exciting puzzle game. Put every ball into a combo while they try to roll away and fall down in a realistic environment. Make use of stone walls and plates, bonus balls and nature forces such as wind and gravity. Nice graphics and effects, realistic physics, smooth oriental-style music, three game modes (Strategy, Arcade, Puzzle), Worldwide Hall of Fame and much more.

A set of modernized 3D pong style games combining the best features of squash and tennis. The game space is a cubic room. The back wall is defended by your opponent (the computer) and the front wall (behind you) is defended by you. The aim of the game is to make the ball hit the back wall of the game cube while preventing the ball from hitting the front wall of the game cube. There are three variants of the game: Arcade (continuously increasing skill of your opponent), Match (played according to the classic rules of tennis) and Discovery (a pleasant way of opening beautiful pictures on each wall by making the ball strike them). Each variant of the game has its own options and scoring rules. Both you and your opponent strike the ball with rackets that can move on the planes of the front and back walls respectively. The ball's trajectory depends on the position and velocity of either racket at the moment it strikes the ball, i.e. the racket lets you skew and curve the shots. The ball may touch the side walls of the cube, which can change its trajectory. A thin white frame moves along the side walls with the ball so you can feel its position easily. There is no gravity in the game; all four sides (left, right, up and down) are equivalent. When your opponent misses the ball so it hits the back side of the cube outside your opponent's racket you win. If you miss the ball and it hits the front side of the cube you lose. You always start each game, i.e. the service is always yours. You can change the style of the cube sides' decoration, the ball size and the skill of your opponent.
