This is more of an interesting observation that I have made about Hinduism and one of the theories of end of universe

Let’s start with defining the Big Crunch.

Before we can do that we must explain big bang theory

According to the Big Bang model, the Universe expanded from an extremely dense and hot state and continues to expand today. A common analogy explains that space itself is expanding, carrying galaxies with it, like raisins in a rising loaf of bread. The graphic scheme above is an artist’s concept illustrating the expansion of a portion of a flat Universe.

Now I think this was simple enough to explain . All the matter was in universe was concentrated in a very small shell. It got unstable and a big bang.

As of now the big bang theory is the most accepted to all theories. It is  reinforced by the doppler’s effect as observed by hubble telescope

Now the Big crunch

The big crunch is again a theory, which is still a not so widely accepted theory, now it says that if the universe is finite and the galaxy’s, which are moving away from each other after the Big Bang , do not reach an escape velocity then they will all start attracting each other at one point in time and start collapsing into each other.

This starts of a chain reaction and eventually every thing collapses into each other and everything comes down to one big shell.

If the universe is finite in extent and the cosmological principle (not to be confused with the cosmological constant) does not apply, and the expansion speed does not exceed the escape velocity, then the mutual gravitational attraction of all its matter will eventually cause it to contract. Because entropy continues to increase in the contracting phase, the contraction would appear very different from the time reversal of the expansion. While the early universe was highly uniform, a contracting universe would become increasingly clumped. Eventually all matter would collapse into black holes, which would then coalesce producing a unified black hole or Big Crunch singularity.

Now this theory at the moment is not very popular

Recent experimental evidence (namely the observation of distant supernova as standard candles, and the well-resolved mapping of the cosmic microwave background) have led to speculation that the expansion of the universe is not being slowed down by gravity but rather accelerating. However, since the nature of the dark energy that drives the acceleration is unknown, it is still possible that it might eventually reverse sign and cause a collapse.^[3]

Coming to Hinduism and its origin

The Nasadiya Sukta of the Rig Veda describes the origin of the universe. The Rig Veda’s view of the cosmos also sees one true divine principle self-projecting as the divine word, Vaak, ‘birthing’ the cosmos that we know, from the monistic Hiranyagarbha or Golden Egg ^[7].

Now the golden egg has a importance here.

In the above Gif picture you can see that the universe collides into one big shell like thing. Could this be possibly to what the Rig veda was referring to?

More from Rig veda.

Once the Universe has been destroyed by Shiva, Brahma starts the creation once again. This creation-destruction cycle repeats itself almost endlessly

Both the Rig Veda and Brahmanda Purana describe a universe that is cyclical or oscillating and infinite in time. The universe is described as a cosmic egg that cycles between expansion and total collapse. It expanded from a concentrated form — a point called a Bindu. The universe, as a living entity, is bound to the perpetual cycle of birth, death, and rebirth.

The later Puranic view asserts that the Universe is created, destroyed, and re-created in an eternally repetitive series of cycles. In Hindu cosmology, a universe endures for about 4,320,000 years—one day/Kalpa of Brahma, the creator) and is then destroyed by fire or water elements. At this point, Brahma rests for one night, just as long as the day. This process, named Pralaya (Cataclysm), repeats for 100 Brahma years (311 trillion, 40 billion human years) that represents Brahma’s lifespan.

Further more in the veda it is said that

Indra and the Ants

In this story from the Brahmavaivarta Purana,^[14][15] Indra defeats V?trá and releases the waters. Elevated to the rank of King of the gods, Indra orders the heavenly craftsman, Vishvakarma, to build him a grand palace. Full of pride, Indra continues to demand more and more improvements for the palace. At last, exhausted, Vishvakarma asks Brahma the Creator for help. Brahma in turn appeals to Vishnu, the Supreme Being.

Vishnu visits Indra’s palace in the form of a brahmin boy; Indra welcomes him in. Vishnu praises Indra’s palace, casually adding that no former Indra had succeeded in building such a palace. At first, Indra is amused by the brahmin boy’s claim to know of former Indras. But the amusement turns to horror as the boy tells about Indra’s ancestors, about the great cycles of creation and destruction, and even about the infinite number of worlds scattered through the void, each with its own Indra. The boy claims to have seen them all. During the boy’s speech, a procession of ants had entered the hall. The boy saw the ants and laughed. Finally humbled, Indra asks the boy why he laughed. The boy reveals that the ants are all former Indras.

Another visitor enters the hall. He is Shiva, in the form of a hermit. On his chest lies a circular cluster of hairs, intact at the circumference but with a gap in the middle. Shiva reveals that each of these chest hairs corresponds to the life of one Indra. Each time a hair falls, one Indra dies and another replaces him.

No longer interested in wealth and honor, Indra rewards Vishvakarma and releases him from any further work on the palace.

Well it all does make some sense, doesn’t it now.

Every time the universe is destroyed by the big crunch or the golden egg  what ever you might choose to call it, it is reborn again with the big bang and the circle of life continues, A new Indra is born and a new human life.

It all seems a bit far fetched and unrealistic, but hey it might just happen.

The universe might not be all that infinite. I mean we as humans have a no idea. It can be like a ripple in a tub of water. Once it reaches the end of the universe, it will come colliding and collapsing into a golden egg.

Well it is a bit hard to believe that the universe has a limit, but then. you never know that the Dark matter which is accelerating the universe right now, might get to the end of the universe .

Anyway I am no astro physicist , Please leave your comments and brick bats here.
