Japan tops world broadband study – Only Japan has the broadband quality to cope with next-generation internet applications, a new study has revealed.
Only Japan has the broadband quality to cope with next-generation internet applications such as video on demand, as well as peer-to-peer file sharing. Most ISPs have used flat rate pricing model. Overselling bandwidth is regular practice. Some ISPs estimate that about 5% of users consume about 50% of the total bandwidth. Top quality broadband nations:
Japan
Sweden
Netherlands
Latvia
Korea
Switzerland
Lithuania
Denmark
Germany
Slovenia
According to study:
Japan’s early commitment to investing in broadband made it the only country prepared to deliver the necessary quality for next-generation web applications over the next three to five years.
Without high-quality broadband, we will not be able to take full advantage of the next wave of productivity, collaboration and entertainment that can be gained from the web.
The standard broadband technologies in most areas are DSL and cable modems. However, use of newer technologies such as VDSL, optical fiber connections may make transmission more cost effective in a long run than copper wire technology.
Black hole pictures – about a theoretical region of space in which the gravitational field is so powerful that nothing, not even electromagnetic radiation.
A black hole is created when a giant star is died and it creates a region in space with extremely high gravitational field. The gravitational field so strong that nothing can escape from it. There are many popular myths concerning black holes, many of them perpetuated by Television and Hollywood movies. I strongly suggest you read this Nasa page which explains “Black Holes.”

Many of my friends are not aware of the Big Bang and CERN experiment which may find answers to some of the biggest questions about our world and universe.

What is the big bang model?
According to the Big Bang model, the universe expanded from an extremely dense and hot state and continues to expand today. A common and useful analogy explains that space itself is expanding, carrying galaxies with it, like raisins in a rising loaf of bread. General relativistic cosmologies, however, do not actually ascribe any ‘physicality’ to space.
More about CERN and LHC
The European Organization for Nuclear Research (CERN) is the world’s largest particle physics laboratory, situated in the northwest suburbs of Geneva on the Franco-Swiss border.
The essential idea is that the universe has expanded from a primordial hot and dense initial condition at some finite time in the past and continues to expand to this day. The CERN is trying to create the big bang in a lab using LHC.
The Large Hadron Collider (LHC) is the world’s largest and highest-energy particle accelerator complex, intended to collide opposing beams of protons charged with approximately 7 TeV of energy. Its main purpose is to explore the validity and limitations of the Standard Model, the current theoretical picture for particle physics. It is theorized that the collider will produce the Higgs boson, the observation of which could confirm the predictions and missing links in the Standard Model, and could explain how other elementary particles acquire properties such as mass.
The LHC has been in construction for some 13 years. According to BBC:
Scientists have hailed a successful switch-on for an enormous experiment which will recreate the conditions a few moments after the Big Bang.
They have now fired two beams of particles called protons around the 27km-long tunnel which houses the Large Hadron Collider (LHC).
The first beams were circulated through the collider on 10 September 2008, and the first high-energy collisions are planned to take place after the LHC is officially unveiled on 21 October 2008.
