Theory of Relativity and Spacewarps

Since its discovery, Einstein’s theory of Relativity has fascinated both scientists and common man alike. It is due to this fascination that the ideas like curved space, singularities are popular among the general public.

The concepts of Relativity are not of everyday experience and thus, somewhat hard to visualize. Same applies to the concept of spacewarps. By the theory, the presence of masses in space curves its geometry. Gravity, which Newton suggested as a force, is the curvature of space as per the relativistic perspective. When it comes to spacewarps, Euclidean Geometry, which is based on flat space-time does not hold good. Bodies following straight paths (as appears to them) in this curved world actually move in circular or elliptical paths. Even light, when moves through this space of high curvature (like the vicinity of a massive star), appears to be deflected by the star. But though spacewarps are discovered through relativity theory, it is these spacewarps that possibly are the limitations to this theory.

Relativity, in one of its postulates, suggests that laws of nature are same everywhere. But this theory is based on nearly flat and not extremely curved space-time. The theory predicts the breakdown of itself when subjected to very intensely curved space, as in singularity, or space-time boundary. The problem of singularities can be solved with the help of the Quantum Theory.

Some facts based on Science

Mercury is a metal in liquid at room temperature. But now we can convert it to solid state even when there is no reaction in the chemistry to do so. A Shivling is made by solidifying mercury. Even the famous Paras stone is made of mercury. It is an ayurvedic element. There is one more property of mercury, i.e. it absorbs poison. This is the reason why Rajas used to drink in mercury glasses, so that any poison in their drinks is completely absorbed by the mercury. The glass used to turn blue on absorbing poison. Mercury absorbs Gold also; it literally eats it because there is no increase in the weight of mercury after absorbing gold.

When a metallic rod is hit by lightening, it glows in the dark. If we cover it with rubber and stand holding it in front of any running engine, the engine will cease immediately. This is used in missiles and rockets these days. It was also used in Mahabharata and Ramayana to destroy the powerful weapons of their enemies. If this rod is kept in front of a bag full of rice, it will convert the rice into powder within seconds.

Lord Krishna always used to wear a peacock’s feather on his head which had eyes on both its sides. This kind of feather has very powerful magnetism. If this feather is kept between two incense sticks (agarbatti), it attracts the smoke in its direction and as a result all the smoke rises up from the feather only. This characteristic is said to be used by lord Krishna in the great battle of Mahabharata.

Why do people worship the Peepal tree? It gives out Oxygen day and night while always consuming Carbon Dioxide from the atmosphere.
