Here are the results of perhaps the first major study in this area:
Starting the school day 50 minutes later has a significant positive effect on student achievement, which is roughly equivalent to raising teacher quality by one standard deviation. [Source]
Basically the finding is this:
Our results show that starting the school day later in the morning has a significant positive effect on student academic achievement. We find that when a student is randomly assigned to a first period course starting prior to 8 am, they perform significantly worse in all their courses taken on that day compared to students who are not assigned to a first period course. Importantly, we find that this negative effect diminishes the later the school day begins.
We verify that the negative start time effect is not solely driven by worse performance in the first period class. Hence, our results show that student achievement suffers from earlier start times in not only courses taken during the early morning hours, but also throughout the entire day.

On 3 June 2010 I asked: Why does energy “travel” in “circles” inside an atom? And later elaborated that matter is an energy trap.
Basically I've suggested that there is a form of super-high frequency energy that that travels at speeds far greater than the speed of light, and this super-energy BENDS space so extensively (makes it "circular", so to speak) that it gains the properties of matter.
There is NO MATTER in this universe. Only energy. That is my basic point.
Today, it has been confirmed that
An international team of scientists says it has recorded sub-atomic particles travelling faster than light – a finding that could overturn one of Albert Einstein's long-accepted fundamental laws of the universe. [Source]
This is the first serious evidence I've seen that my hypothesis is likely to be correct.
In my view these "sub-atomic particles" will be found, upon further analysis, to be composed of HIGH FREQUENCY AND HIGH SPEED ENERGY. It might be impossible to "break" into the final sub-atomic particle, though, for the energy required to break that particle will exceed anything that can be created by man.
Anyone has any thoughts on this?
Think of this as breaking the light speed barrier, a phase change. At the initiation of the Big Bang the energy was so intense that its "force" must have radiated out at a range of speeds, including those greater than the speed of light. All energy – not necessarily a single photon; could be a small bundle of energy – that was so thrust at speeds greater than light "converted" into matter (sub-atomic). The stuff that remained at speeds equal to that of light became heat and light.
