How the PYRAMIDS were built???


Well.........it has always been a mystery.......dat how the pyramids were built???.......without the use of cranes and other important equipments.......

How the workers were able to move the 2000kg block up the pyramid?????........

So.if u have been thinking abt these questions for long...........then here's the answer.......


There are many theories about how the pyramids were built. Some are very unbelievable and others are very possible. One of the most odd and outrageous theories it that aliens built the pyramids. This is a completely dumb idea, since we have proof that the Ancient Egyptians built the pyramids. So, therefore, credit should be given were it is deserved.


Then, there are many theories about how the Egyptians built the pyramids.
One theory is that the egyptians built one large ramp. This was quickly ruled out because the ramp would have to be a mile long in order for the slant of it to be feasable. The ramp would have used more material than the pyramid itself..........he he...
A second theory claims that there was a singular ramp spiraling around the pyramid. This will clearly not work because in order for the ramp to extend from the bottom to the top, the way the ramp would be, you wouldn't be able to cover all of the area and you would have a rather lacy pyramid. The angles would we so sharp that you wouldn't have been able to move two ton blocks around corners.
One well known theory as to how the pyramids were built is that of Mark Lehner's. Lehner works at the University of Chicago's Oriental Institute. Lehner has spent much of the last 13 years excavating at the site of the Great Pyramid and let loose a team of diggers on a field covered with garbage.
Lehner's theory, liked by many people, is the theory of Tafla. Tafla is a clay that is very strong when it is dried but is easily destroyed by a pick ax. When Tafla is wet it is very slippery and could have been used to move the 2 ton blocks. With a ramp of Tafla, a big crew could move the 2 ton blocks up the side of a pyramid. A pole was in a corner of the pyramid could swing the blocks around. This was proven by a NOVA experiment on a smaller scale.
Well I think this is the most logical theory with one exception: it still doesn't cover enough of the pyramid's area. It is believed that there were four ramps spiralling upward, each starting from one of the four corners. All other theories we've seen have been disproven in some way. No one really knows for a fact how the pyramids were built — they can only make practical assumptions. Lehner's theory has an explanation for everything and has been proven by NOVAk. There is no way to determine that it is true, but of the theories we've seen, it is by far the best.
You can make your own decisions as to who you think built the pyramids or how you think they did it. Just try to think things through completely and look for any possible setbacks........

SPEED OF LIGHT-No more the limit......



Scientists claim to break the speed of light-barrier


If zooming beyond the local speed limit is punishable by law, then some scientists may have a gargantuan speeding ticket to pay.
In a controversial experiment reported in this weeks journal Nature, scientists at the NEC Research Institute in Princeton, New Jersey claim to have broken the ultimate speed limit -- the speed of light. Though hotly contested, some say this achievement could dramatically increase the speeds at which we can send and receive information.
Taught in physics classes the world over, Albert Einsteins theory of special relativity holds that no object or information can move faster than the speed of light in a vacuum, or 186,000 miles (300,000 kilometers) per second. But NECs Lijun Wang says he created an experiment in which a light beam raced through a gas-filled chamber so quickly, it exceeded the speed of light by a factor of 300. Whats more, the light pulse appears to have left the confines of the chamber before it even entered a seemingly impossible occurrence according to theories of causality, which predict that causes must always precede their effects.
"It sounds crazy, but this can actually occur," said Raymond Chiao, a physicist at the University of California at Berkeley. Chiao, one of a group of researchers who have been working to break the speed-of-light limit, explained that although a common object such as a baseball could never be flung faster than the speed of light, pulses of energy with certain complex properties have been known to bend the rules.

"It sounds crazy, but it actually can occur."

In fact, several recent experiments, including one done by Chiao earlier this year, have pointed to energy pulses zooming faster than light speed. Yet each of these experiments has been encumbered by severe limitations on measurement or observation of the energy pulses. In contrast, this latest experiment is being touted by some as the most dramatic example yet of light breaking its own speed barrier.

"The effects are much larger and more spectacular" than previous observations, said Chiao.
In Wangs experiment, a pulse of light passed through a small chamber filled with atoms of elemental cesium. A light beam traveling through such a medium has two different velocities a velocity for the individual light waves in the beam and a group velocity for the entire beam. Oddly, some light waves in the beam can actually travel backward for miniscule amounts of time, creating a sort of "tail" behind forward-moving waves. As such, a light wave and its tail can leave the gas cavity at different times, creating the effect that the light beam has left the cavity before its even entered.
Confused? Youre not alone. In fact, even scientists who are familiar with this area of study are unsure about the details of Wangs experiment. And many scientists said the experiments results are still open to interpretation.

William Happer, a physicist at Princeton University argued that several specific problems exist with the experiment, including the fact that pulses get distorted when passed through any media other than a vacuum, or empty space. In addition, he said Wang and his colleagues performed the experiment in a way that doesnt tell the whole story, and that it can be interpreted incorrectly. "This is anything but dramatic," said Happer. "If you look at the data, theres essentially no evidence that [the beam] is going faster than the speed of light."

Whats more, most scientists agree that even if such a beam can be proved speedier than light, it would probably not be able to carry any information. Such a feat could conceivably allow data to be sent back in time, thus violating laws of causality and sending quantum physics into disrepair.
Others are more optimistic as to the possible benefits of Wangs experiment. "For some applications, for example, to computer circuits, this might be very important and useful," said Chiao.

Are we heading towards our end?????

Hi!!!.....i m
Nitesh....
I m a Mechanical Engineering student of H.B.T.I.....

I had been surfing the news channels for few days..........which showed the news of our end.............i.e our world's going to end in 2012........i know it sounds horrifying........but this inevitable fact(JUDGEMENT DAY).........has started to show its sign.........

Besides dat,i also read about the prediction made by NOSTRADAMUS......abt our world's end.....in 2012......
I know.....it sounds a bit crazy dat....... how could a man of 16th century make predictions abt 21st century......???then lemme tell u abt some of his predictions which turned out to be true in PAST.........

  1. NOSTRADAMUS was able to predict about 9/11......
  2. NOSTRADAMUS was able to predict about ADOLF HITLER and his dictatorship....
  3. NOSTRADAMUS was able to predict about OSAMA BIN LADEN and his terror.....

U can chk out the details about these predictions at......http://www.armageddononline.org/nostradamus2.php

so to ignore his prediction about our end in 2012..............is nt ezyyyy........

SO guys,....WAT DO U ALL THINK???
ARE WE HEADING TOWARDS OUR END?????
