WORM HOLE  Introduction Wormhole is a highly speculative idea of modern physics, wormholes are theoretical possibilities allowed in the mathematical framework of Einstein's general theory of relativity. From Einstein theory of relativity any matter has mass cannot attain the speed of light. For this  a matter that posses mass needs infinite energy to achieve the speed of light.  A doubts in mind arises, if scientist cannot designed a spacecraft that can travel at a speed of light. So why scientists are trying to figure out the life sustaining planet that are millions of light years far way from us ?  The reason is hidden in the mathematical equation which gives us idea that we can travel from one point to another point in the universe without breaking the laws of Theory of Relativity . According Einstein and Nath Rosen, some time due to curvature in the spacetime  , a shortcut path is created between the two distinct points in the ...

Brane (physics) Brane - Many mathematicians and astrophysicist considering the existence of other universes must entertain the possibility of more than one realms that the four we know as spacetime , the three dimensional and the fourth time proposed by Einstein.       More than four dimensional In one version of string theory, physicists allow for eleven dimensions, including seven remain imperceptibly "curled up". The visible universe could be a four dimensional membrane or Brane for short, moving through unseen dimensions. Other Branes or parallel universe may also exist in fifth dimension that we cannot perceive. A cross section of a  Calabi–Yau manifold Some scientists propose that our would be universe existed as a Brane into which another Brane collided in a uniform fashion, generating the heat energy and expansion accounted for in the big bang . But these theories are now exist in the mathematical modals, which requires a add...

DARK ENERGY Credits: NASA.gov Scientists have given the name dark energy because of the property of expansion generating unknown force or substance of the universe. Dark energy is just reverse of gravity. It pushes matter away rather than attracting them together. It is unknown whether the laws of physics or the general theory of relativity accounts for dark energy.   In 1998 astronomers studying supernovae found them dimmer than anticipated. This meant both they were farther away as the universe is expanding faster than expectations . In theoretical it is almost impossible for travelling one galaxy to other. The nature of dark energy about scientists know is very little.  If it is stable , it could continue to expand and accelerate forever. If it is unstable  the universe could ultimately will pulled apart like "Big rip". If it has the capacity to change , it could gradually de -accelerate and become an attractive force that contracts the un...

What is the definition of a Galaxy?                                                  Majestic spiral Galaxy NGC 4414 A galaxy is a huge mass of stars, nebulae, and interstellar material. The smallest galaxies contain about 100,000 stars, while the largest contain up to 3000 billion stars. There are three main types of galaxies classified according to their shape; elliptical, which are oval-shaped, spiral, which have arms spiraling outwards from a central bulge (those whose  arms spiral from a bar-shaped bulge are called spirals) and irregular, which has no obvious shape? Sometimes, the shape of a galaxy is distorted by a collision with another galaxy. Quasars are thought to be galactic nuclei but are so far away that their exact nature is still uncertain. They are compact, highly luminous objects in the outer reaches of the known uni...
