The material world according to the Vedas

We are not seeing the full picture of the material universe with our biological eyes and its extended enhancements of telescopes and space probes that is also made of gross matter like our gross material bodies.

You cannot use gross matter to perceive the subtle or ethereal realms, that is why modern scientists cannot see the heavenly or even the hellish worlds that are also in subtle matter. Technically what we are trying to understand here is what happens after death of the biological material body and to where the subtle material vessel, that houses the soul or jiva while in the material creation, goes next.

This is all about the after life and ultimately re-establishing our eternal original relationship with Krishna beyond the gross and subtle bodies and worlds of this temporary material universe

There are 14 planetary systems in the material universe that are all different levels of conscious awareness or dimensions, some are subtle matter and there are also other dimensions of biological life.

We are limited to only one of those gross material realities that we perceive with our gross biological body in our dimension with its extensions of space probes, telescopes and the Large Hadron Collider, etc.

The 'subtle' material universe and parallel universes that are like ours as well as the ‘ethereal body’ that underlies all biological bodies, has not yet been discovered by modern science, neither has other dimensions of biological life in parallel realities yet been discovered although modern science of string theory is getting close. Although the ‘ethereal body’ can never be discovered by using ‘gross’ matter on our biological plane

In other words you cannot see the full picture of the material universe with biological matter or with Kali yuga limited science that is restricted to this present day lower conscious dimension, only by developing higher realms of consciousness and NOT through mundane telescopes can one perceive the material universe in its full potential, a devotee sees through the eyes of sastra and ones self awareness
