The Rig Veda describes the primordial state of the universe as a single, unified entity known as 'Hiranyagarbha', which means 'golden womb'.

The Rig Veda contains the earliest reference to the idea of a cosmic explosion in the hymn known as the 'Nasadiya Sukta'.

The Nasadiya Sukta describes a cosmic explosion that is similar to the Big Bang theory in modern cosmology.

The Nasadiya Sukta states that before the Big Bang, there was 'neither existence nor non-existence'.

The Nasadiya Sukta does not specify the source of the energy that caused the Big Bang, leaving it open to interpretation.

The Nasadiya Sukta describes the universe immediately after the Big Bang as a 'hot, dense soup of particles'.

The Nasadiya Sukta describes the universe as cooling and expanding after the Big Bang.

The Vedic texts suggest that the universe undergoes a series of cycles of expansion and contraction, known as 'kalpas'.

The concept of the Big Bang Theory in Vedic texts is similar to modern scientific theories in that it describes a cosmic explosion that gave rise to the universe. However, there are some differences between the two, such as the role of divine beings in the Vedic account.

The concept of the Big Bang Theory in Vedic texts demonstrates the harmony between science and religion by showing that ancient spiritual texts can contain insights that are consistent with modern scientific theories.
