A multiverse is a hypothetical set of all universes that may exist. It includes our universe and any other possible universes with different physical laws, dimensions, histories, or structures. The concept of a multiverse has been discussed in various fields, such as cosmology, physics, philosophy, and fiction. Some scientists and philosophers argue that the multiverse is a logical consequence of some theories of nature, such as quantum mechanics, inflation, string theory, and the anthropic principle. Others argue that the multiverse is a speculative idea that cannot be tested or verified by observation or experiment.
Multiverse in Hindu Mythology
Hindu mythology contains many references to the idea of multiple worlds or universes. For example, the Rigveda, one of the oldest Hindu scriptures, mentions seven higher worlds (bhuvanas) and seven lower worlds (patalas) inhabited by different beings and gods. The Puranas, a collection of ancient stories and legends, describes 14 worlds that are divided into three regions:
- The upper region (urdhva loka)
- The middle region (bhu loka)
- The lower region (adho loka)
The upper region comprises six heavenly worlds: Bhuh, Bhuvah, Svah, Mahah, Janah, and Tapah. The middle region consists of one earthly world: Bhuvar. The lower region comprises seven nether worlds: Atala, Vitala, Sutala, Talatala, Mahatala, Rasatala, and Patala.
The Hindu Cosmology.
The Hindu cosmology also describes the concept of kalpas, or cycles of creation and destruction. According to this concept, each universe has a lifespan of one day of Brahma, the creator god. A day of Brahma lasts for 4.32 billion human years, followed by a night of Brahma of equal duration. During the night of Brahma, the universe dissolves into a state of chaos and darkness. At the end of the night of Brahma, a new universe is created by Brahma’s will. This cycle repeats endlessly for 100 years of Brahma, equivalent to 311 trillion human years. After 100 years of Brahma, he dissolves into the supreme reality of Brahma, which is beyond time and space. After a period of rest, a new Brahma emerges from Brahman and creates a new set of universes.
The Hindu cosmology also suggests that there are multiple Brahmas and multiple universes that coexist simultaneously. Each Brahma has his universe that he creates and destroys according to his cycle. These universes are separated by layers of water that surround them like shells. The water is a barrier that prevents communication or interaction between different universes. However, some Hindu texts also mention the possibility of traveling between other universes through mystical means or divine intervention.
Interdimensional travel is the hypothetical ability to move between different dimensions or universes. It is often depicted in science fiction and fantasy stories as a way of exploring alternative realities or timelines. Some possible methods of interdimensional travel include wormholes, portals, parallel mirrors, quantum tunnels, dimensional gates, or psychic powers.
Interdimensional travel is not proven possible by any scientific evidence or theory. However, some physicists have speculated that interdimensional travel may be possible under certain conditions or assumptions. For example,
- Some versions of string theory suggest that there are extra dimensions beyond the four dimensions of space and time we perceive. These dimensions may be curled up at microscopic scales or extend infinitely in parallel with our dimensions. If these extra dimensions exist, accessing them through high-energy experiments or advanced technology may be possible.
- Some versions of inflation theory suggest that multiple regions or bubbles of space-time have different physical properties and histories. These regions or bubbles may be separated by vast distances or thin membranes that prevent them from interacting with each other. If these regions or bubbles exist, it may be possible to travel between them through wormholes or quantum fluctuations.
- Some versions of quantum mechanics suggest that multiple branches or histories of reality result from every quantum event or measurement. These branches or narratives may coexist in a superposition state until an external agent observes them. If these branches or histories exist, it may be possible to travel between them through quantum decoherence or entanglement.
However, these speculations are based on theoretical models not confirmed by observation or experiment. They also face many challenges and paradoxes, such as the conservation of energy, the causality principle, the grandfather paradox, and the information paradox. Therefore, interdimensional travel remains a controversial theoretical concept that science has yet to prove possible or impossible.
