The new Singapore Street Circuit which will host the Singapore Grand Prix at night.
It has been confirmed that Singapore will host a Grand Prix from 2008 for the next five years. It will be a street circuit, with the route designed by Hermann Tilke. It has been confirmed that the Grand Prix will be a night race, with a start time of 20:00 local time and run in an anti-clockwise direction to enhance safety. It has also been revealed that practice sessions and qualifying will take place at night.

The European Grand Prix will take place at the Valencia Street Circuit in 2008, changing from the Nürburgring which hosted the event up until 2007. Because both German circuits share the right to host an F1 race, the German Grand Prix will take place at Hockenheim in 2008. It will continue to alternate between these two circuits yearly.

It has been confirmed that the Indianapolis Motor Speedway will not hold a Grand Prix in 2008; however, a possible return to Indianapolis in the future has not been completely ruled out.
The 2007 French GP was said to be the last to be held at Magny-Cours. Alternatives for the French Grand Prix included Paul Ricard or a new circuit near Disneyland Paris or Charles de Gaulle airport likely to host the event from 2009. However on 24 July 2007 it was reported that Bernie Ecclestone had "agreed in principle to maintain the race at Magny-Cours in 2008, and even 2009, if there were no other alternative."

The 2008 season also sees changes to the race start times for China, moved to 15:00 and Australia, moved from its traditional 14:00 slot to 15:30.

A black hole is a region in space where gravitational force is so strong that nothing could ever escape from it. As black holes traps light they are invisible. It is called a hole because nothing can ever come out of it. Light or other electromagnetic radiation can never escape out it. Therefore it is called a black hole. The term ‘black hole’ was given by John Archibald Wheeler. Before that these objects were referred to as ‘frozen stars’.
The fundamental explanations of these black holes are based on the equations in the theory of general relativity developed by the German physicist Albert Einstein, which was published in 1916. These black holes are so dense that not even light can escape its gravitational effect. Nothing could travel faster than light. Therefore nothing can escape from inside a black hole.
Even before Isaac Newton’s time, scientists speculated that such things could exist. But now they are accurately described using General Theory of Relativity proposed by Einstein. This brings us to the conclusion that block holes are nothing but fascinating objects in space where space and time, both become so warped that even time practically stops in the vicinity of a black hole
