This blog explains the concept and working of Wormholes.

A wormhole is a solution of the Einstein field equations having a non-trivial structure linking separate points in spacetime, much like a tunnel with two ends, each at separate points in spacetime. Such connections are consistent with the general theory of relativity, yet their existence remains hypothetical.

A wormhole may connect extremely long distances such as a billion light years or more; short distances such as a few meters; different universes; and/or different points in time. This is proposed in Albert Einstein's special theory of relativity, where the combination of space and time into a single spacetime continuum could theoretically allow one to traverse both space and time using a wormhole with the correct conditions.

Schwarzschild wormholes

Schwarzschild wormholes, also known as Einstein–Rosen bridges (named after Albert Einstein and Nathan Rosen),are connections between areas of space that can be modeled as vacuum solutions to the Einstein field equations, and that are now understood to be intrinsic parts of the maximally extended version of the Schwarzschild metric describing an eternal black hole with no charge and no rotation. Here, "maximally extended" refers to the idea that the spacetime should not have any "edges": it should be possible to continue this path arbitrarily far into the particle's future or past for any possible trajectory of a free-falling particle (following a geodesic in the spacetime).

Traversable wormholes


Traversable wormholes would allow travel in both directions from one part of the universe to another part of that same universe very quickly or would allow travel from one universe to another. The possibility of traversable wormholes in general relativity was first demonstrated in a 1973 paper by Homer Ellis and independently in a 1973 paper by K. A. Bronnikov.

Where is the Centre of Universe

Where is the Centre of Universe Where is the Centre of Universe? What Lies in the centre of the Universe? Case 1: The Observable Universe We are, by definition, at the very center of our observable universe. However, an alien species on a planet one billion light years away from us is at the center of their observable universe, which is very different from ours. Wherever you go, you will be at the center of your observable universe, because the observable universe is the part of the universe that you can see, and the light from all the stars and galaxies on the edge of the observable universe takes the same time to get to you, no matter which direction it came from. So you can imagine the observable universe as a sphere (or ball) that is centered on you and follows you wherever you go. However, there is nothing special about you specifically; anyone else in the universe experiences the same thing. Case 2: The Entire Universe It should be stressed that in contrast to the obs

Oumuamua - Solar System's First Interstellar Visitor

 Oumuamua  - Solar System's First Interstellar Visitor ʻOumuamua is the first known interstellar object to pass through the Solar System. Formally designated 1I/2017 U1, it was discovered by Robert Weryk using the Pan-STARRS telescope at Haleakala Observatory, Hawaii, on 19 October 2017, 40 days after it passed its closest point to the Sun. When first seen, it was about 33,000,000 km (21,000,000 mi; 0.22 AU) from Earth (about 85 times as far away as the Moon), and already heading away from the Sun. Initially assumed to be a comet, it was reclassified as an asteroid a week later, and finally (6 November 2017) as the first of the new class of interstellar object. ʻOumuamua is a small object, estimated to be about 230 by 35 meters (800 ft × 100 ft) in size. It has a dark red color, similar to objects in the outer Solar System. ʻOumuamua showed no signs of a comet tail despite its close approach to the Sun, and has significant elongation and rotation rate, so it is though

Gravitational Waves & LIGO

Gravitational Waves & LIGO This blog explains Gravitational Waves in Hindi language. It also explains LIGO in Hindi as well as How LIGO observatory Works. What are gravitational waves? Put simply, gravitational waves are ripples in the otherwise tough, stiff fabric of spacetime produced by the most violent phenomena the cosmos can offer—things like exploding stars and collisions between ultradense neutron stars or merging black holes. Gravitational waves are washing over Earth all the time, but our instruments have not been sensitive enough to detect them until very recently. Who first came up with the idea of gravitational waves? In 1916, Albert Einstein suggested that gravitational waves could be a natural outcome of his general theory of relativity, which says that very massive objects distort the fabric of time and space—an effect we perceive as gravity. Accordingly, very massive objects spiraling toward each other should wrinkle space-time and send those distorti
