Warp Drive Engine Could Suck Earth Into Black Hole

Posted on June 12, 2009 by Rashid Faridi

According to new calculations by Italian physicists, a warp drive could easily create a black hole that would incinerate any passengers on a space craft and then suck Earth into a black hole.

In normal physics, nothing can move faster than the speed of light. Einstein’s theory of relativity forbids it. In normal space any object approaching the speed of light will increase in mass exponentially, and require an exponential increase in the amount of power needed to propel it forward.

There are two exceptions to this rule however- Worm Hole and Warp Drive…

Warp drives are the second and more appealing option. A ship can’t move through space faster than the speed of light. But with enough energy, space itself can move faster than the speed of light. Known for the Mexican physicist Michael Alcubierre who originally developed the idea in the 1990’s, an Alcubierre warp drive would create a bubble of energy behind the ship and a lack of energy in front of the ship, like a giant cosmic wave a space ship could surf. That particular section of space can travel faster than the speed of light in the surrounding space, and anything on or in that bubble will accelerate with it.

El Niño is coming back

Posted on June 11, 2009 by Rashid Faridi

Ocean temperatures in the equatorial Pacific are showing signs that an old acquaintance is about  to return.Sea surface temperatures have warmed across the Pacific’s midsection during the Spring, and more importantly, a large pulse of subsurface warmth has propagated from west to east.

El Niño conditions have a variety of impacts around the globe, although every event is different. Typically, upper-level westerly winds intensify, a circumstance that could suppress the development of some Atlantic hurricanes this summer. During winter, the North Pacific jetstream flattens its trajectory and moves farther south, which usually brings more warm winter storms across Southern California and Southeastern US. The Pacific Northwest often experiences warmer and drier winters.

New Doubts About Dinosaur-bird Links

Posted on June 10, 2009 by Rashid Faridi

During walking and running in birds, hindlimb movement is generated primarily at the knee and ankle joints; in humans, movement occurs at the knee, ankle and hip joints. The bird's thigh does not move substantially from its nearly horizontal position where it provides rigid lateral support to the thin walled air-sacs of the respiratory system.

Researchers at Oregon State University have made a fundamental new discovery about how birds breathe and have a lung capacity that allows for flight – and the finding means it’s unlikely that birds descended from any known theropod dinosaurs.The conclusions add to other evolving evidence that may finally force many paleontologists to reconsider their long-held belief that modern birds are the direct descendants of ancient, meat-eating dinosaurs, OSU researchers say. …

Overfishing cause Proliferation of Giant Jellyfish

Posted on June 9, 2009 by Rashid Faridi

Giant jellyfish are taking over parts of the world’s oceans as overfishing and other human activities open windows of opportunity for them to prosper, say researchers. Jellyfish are normally kept in check by fish, which eat small jellyfish and compete for jellyfish food such as zooplankton, researchers said. But, with overfishing, jellyfish numbers are increasing….
