WARP DRIVE-- REALITY????

Image
What is the Alcubierre "warp" drive? By Balbeer Singh Danu Visualization of a warp field, according to the Alcubierre Drive.  It's always a welcome thing to learn that ideas that are commonplace in science fiction have a basis in scientific fact. Cryogenic freezers, laser guns, robots, silicate implants… and let's not forget the warp drive! Believe it or not, this concept – alternately known as FTL (Faster-Than-Light) travel, Hyperspace, Lightspeed, etc. – actually has one foot in the world of real science. In physics, it is what is known as the Alcubierre Warp Drive. On paper, it is a highly speculative, but possibly valid, solution of the Einstein field equations, specifically how space, time and energy interact. In this particular mathematical model of spacetime, there are features that are apparently reminiscent of the fictional " warp drive " or "hyperspace" from notable  science fiction  franchises, hence the association. Backgr...

DO TECHYONS REALLY EXIST ???

Image
Tachyons, hypothetical sub-atomic particles which travel faster than light, once attracted a lot of publicity yet we do not hear much discussion of them today. Whatever happened to tachyons? An artist’s impression of the planet Dagon in the Fomalhaut system, some 25 light years from the Sun. Could tachyons take us there in less than 25 years? (Image credit: NASA) Over a century ago, Albert Einstein anticipated odd things happening on a spaceship travelling at speeds close to that of light (roughly 300 000 km/s) and impossible things happening when travelling at more than the speed of light. It is not necessary here and now to go into why this should be, but these predictions are enough to convince much smarter people than me that the speed of light is a fixed, fundamental speed limit in the Universe and that no material objects can ever attain or exceed this crucial speed. However, some theoretical physicists have gone for a walk on the wild side by speculating on the poss...

ISS Daily Summary Report – 12/21/2017

Marrow :  U pon wakeup a 53S crewmember collected breath and ambient air samples. With operator assistance , the subject collected blood samples to support the Marrow investigation. The blood samples were processed in the centrifuge and placed in the Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI).  The Marrow investigation looks at the effect of microgravity on bone marrow. It is believed that microgravity, like long-duration bed rest on Earth, has a negative effect on the bone marrow and the blood cells that are produced in the bone marrow.   Synthetic Bone BioCell Operations:  During yesterday’s scheduled microscope operations for BioCell Habitats A and B, microscope issues inside the Microgravity Science Glovebox (MSG) prevented ground teams from viewing video footage of the growing bone cells from the BioCells. With the deferment of the fixation of BioCell Habitat A, the crew was able to complete one of today’s media exchanges during yesterda...

barycenter

What is a barycenter? Tweet We say that planets orbit stars, but that’s not the whole truth. Planets and stars actually orbit around their common center of mass. This common center of mass is called the   barycenter . Barycenters also help astronomers search for planets beyond our solar system! What is a center of mass? Every object has a  center of mass . It is the exact center of all the material an object is made of. An object's center of mass is the point at which it can be balanced. Sometimes the center of mass is directly in the center of an object. For example, you can easily find the center of mass of a ruler. Try holding your finger under the middle of a ruler in a few different spots. You'll find a spot where you can balance the whole ruler on just one fingertip. That's the ruler's center of mass. The center of mass is also called the center of gravity. But sometimes the center of mass is  not  in the center of t...
