Fourteen Lokas or the Planes of Existence are described in Hinduim.
There are two interpretations of the Lokas.
One is that these are The Stages of mental development in a Spiritual Journey.
Another is that these are Planes of Existence at other levels, complying with Laws that are unique to them, Including the Laws of Physics.
They exist as our earth exists in Time and Space, where the Space Time concepts are different from ours.
It may be noted that the day of the Devas is equivalent to 100 Earth Years.
There is a Mention of Mandhaata visiting Brahma loka for a day and on returning to Earth he finds that 100 Years have lapsed.
I feel that there are two different sets of Lokas that are being spoken in Hinduism.
There are references to Chandra and Surya Lokas, which are not listed in the 14 Lokas List.
These are called Chandra Mandala and Surya Mandala as well.
Mandala may probably mean the sub planetary systems around the Moon and Sun respectively
At the same time the Yoga Schools call various stages of mental development as the level of Chandra, which indicates Mind while Surya indicates
Taking these to mean and comparing them with the Quantum Theory which states that there are other planes where things exist and they do not obey
the Laws of our Earth’s Physical laws.
Latest findings indicate that the Multi verses are Infinite and they depend on the Perceiver and his ability to perceive them.
Hinduism says exactly the same with Time being Cyclic.

““So, the total number of possibilities accessible to any given observer is limited not only by the entropy of perturbations of metric produced by inflation and by the size of the cosmological horizon, but also by the number of degrees of freedom of an observer,” the physicists write.
Professor Arthur Holmes (1895-1965) geologist, professor at the University of Durham. He writes regarding the age of the earth in his great book, The Age of Earth (1913) as follows:
“Long before it became a scientific aspiration to estimate the age of the earth, many elaborate systems of the world chronology had been devised by the sages of antiquity. The most remarkable of these occult time-scales is that of the ancient Hindus, whose astonishing concept of the Earth’s duration has been traced back to Manusmriti, a sacred book.”
Alan Watts, a professor, graduate school dean and research fellow of Harvard University, drew heavily on the insights of Vedanta. Watts became well known in the 1960s as a pioneer in bringing Eastern philosophy to the West. He wrote:
“To the philosophers of India, however, Relativity is no new discovery, just as the concept of light years is no matter for astonishment to people used to thinking of time in millions of kalpas, ( A kalpa is about 4,320,000 years). The fact that the wise men of India have not been concerned with technological applications of this knowledge arises from the circumstance that technology is but one of innumerable ways of applying it.”
When the Hindu calculation of the present age of the earth and the expanding universe could make Professor Holmes so astonished, the precision with which the Hindu calculation regarding the age of the entire Universe was made would make any man spellbound.
The multiverse (or meta-universe) is the hypothetical set of infinite or finite possible universes (including the historical universe we consistently experience) that together comprise everything that exists and can exist: the entirety of space, time, matter, and energy as well as the physical laws and constants that describe them. The various universes within the multiverse are sometimes called parallel universes.
The structure of the multiverse, the nature of each universe within it and the relationships among the various constituent universes, depend on the specific multiverse hypothesis considered. Multiple universes have been hypothesized in cosmology, physics,astronomy, religion, philosophy, transpersonal psychology and fiction, particularly in science fiction and fantasy. In these contexts, parallel universes are also called “alternative universes”, “quantum universes”, “interpenetrating dimensions”, “parallel dimensions”, “parallel worlds”, “alternative realities”, “alternative timelines”, and “dimensional planes,” among others. The term ‘multiverse’ was coined in 1895 by the American philosopher and psychologist William James in a different context.
The multiverse hypothesis is a source of disagreement within the physics community. Physicists disagree about whether the multiverse exists, and whether the multiverse is a proper subject of scientific inquiry. Supporters of one of the multiverse hypotheses include Stephen Hawking, Steven Weinberg, Brian Greene, Max Tegmark, and Alex Vilenkin. In contrast, critics such as David Gross, Paul Steinhardt, and Paul Davies have argued that the multiverse question is philosophical rather than scientific, or even that the multiverse hypothesis is harmful or pseudoscientific.”
