Rig Veda has verses speaking of manojava > speed of light and MunDak Updanishad mentions 7 tongues of Agni (Fire) - 1st is black in colour and the 7th called Vishwa-ruchi which supposedly devours everything. However, there is knowledge embedded in Vedas that modern humans cannot fully understand yet.
Etymology: Vishwa-Ruchi = [The fire that] likes the universe or finds it tasty, has 'ruchi' for the vishwa (world, universe) (as if it were their favorite food hence swallowing it)

The sacred spatial silence is a time-continuous Presence. The Presence, Being, Silence, Silent Existence. Infinite Being is Brahman’. It is said that only 1/4 part of Being is the material universe.
The following is not directly from scripture, but more like an opinion, although scriptures are secretly suggestive, and a Hindu may come to such conclusions:
What is the invisible “Divine Hand” behind the galactic center, the event horizon of the black hole, an exploding supernova, or an evolving society of a species? The answer is Brahman’
The Divine Hand that balances the pull and push at the event horizon of the black-hole at the centre of a galaxy, to keep both the black-hole and galaxy or galaxy-cluster alive – is Brahman' AS VishNu, the all-pervading infinite Silence (Brahman’) playing the role of maintenance and nurture, care.
The Divine Hand behind a healthy expanding galaxy is a sign of material creation, the creative role of Brahman' AS BrahmA (born from VishNu ).
The Divine Hand behind the act of black hole at galactic centers systematically eating up the surrounding galaxy (when the entropy-balance tips in favor of destruction), is Brahman' AS Rudra.
The material outcome of these Divine Intentions and roles, as well as the Divine Energy of Brahman' that makes this happen is Adi-Shakti. (Adi = first, original)
Could those rogue black holes be Goddess KAli (Shakti in a particular state) devouring everything in Her path?
Who are these VishNu, BrahmA, Rudra? The same One, Single space-less timeless formless Presence, Being, called Brahman’, the “Divine Hand” behind the phenomena (but not the phenomena themselves) , simply facilitating the various roles at appropriate times on the time-line. The energy of Brahman' that activates material phenomena is Shakti.
