The Hymn That Ends With a Question

Blogger Journey · Week 1, Post 1 · from The Unmanifest
What the Nasadiya Sukta shares with Big Bang cosmology, and what it does not.

Picture a teacher, three thousand years ago, chanting a creation hymn to his students. They know how such hymns end: a god is named, the god is praised, a blessing follows. This one ends differently. The last line asks whether even the highest overseer of the world knows how it began, and then answers: perhaps he knows not.

That hymn is the Nasadiya Sukta, Rigveda 10.129. My first book begins with it, and so does this blog.

First, what I am not claiming

Many posts online say the Rigveda "described the Big Bang." I do not say that, and my book does not say that. The rishi took no measurements. The Planck satellite carried no metaphysics. What I do claim is narrower and, I think, more interesting: when two very different disciplines push the question of origins to its limit, they arrive at the same kind of wall. Let me show you both sides, and you can judge.

Shabda: what the hymn actually says

The Rigveda is generally dated by scholars to roughly 1500 to 1000 BCE, with the tenth book, where this hymn sits, usually counted among its later layers. Some Indian scholars argue for earlier dates. That question is open, and nothing here depends on it.

The hymn opens with a double refusal. Its first words, nasad asin no sad asit tadanim, give it its name. In Ralph Griffith's 1896 translation:

"Then was not non-existent nor existent: there was no realm of air, no sky beyond it."

Notice what the poet does. Almost every creation story begins from one of two doors: something was already there, or nothing was. The rishi closes both doors. Whatever preceded the world lies beyond the words "being" and "non-being" alike. The second verse adds that there was no death and no immortality, no sign of night or day, and yet tad ekam, "That One," breathed, windless, by its own nature.

Then come the final two verses:

"Who verily knows and who can here declare it, whence it was born and whence comes this creation? The Gods are later than this world's production. Who knows then whence it first came into being?"
"He, the first origin of this creation, whether he formed it all or did not form it, whose eye controls this world in highest heaven, he verily knows it, or perhaps he knows not."

The gods themselves, the hymn says, arrived after creation, so they cannot testify to it. And the overseer may know, or may not (yadi va na veda). The tradition has read this ending in more than one way. The fourteenth-century commentator Sayana, at the Vijayanagara court, read it as saying the origin is knowable only to the Supreme. Others hear in it the same teaching the Upanishads later made explicit as neti neti, "not this, not this": every description of the ultimate falls short. Either way, a scripture chose to preserve a question mark at its summit, and kept it intact through a hundred generations of oral recitation.

Pratyaksha: what cosmology actually says

In 1964 two radio astronomers at Bell Laboratories in New Jersey, Arno Penzias and Robert Wilson, could not get rid of a faint microwave hiss in their horn antenna. They even cleared out the pigeons nesting inside it. The hiss stayed, from every direction, day and night. It turned out to be the cosmic microwave background, the afterglow of the young universe, released about 380,000 years after the Big Bang. It earned them the 1978 Nobel Prize in Physics.

Satellites since then (COBE, WMAP and Planck) have mapped that glow across the whole sky. From it, the Planck team's 2018 results give the age of the universe as about 13.8 billion years. That the universe expanded from a hot, dense state is about as well established as anything in science.

Now follow the story backward and watch what happens. Well-tested physics reconstructs the universe back to a tiny fraction of its first second. But before about 10-43 seconds, the Planck time, general relativity and quantum mechanics cannot both be applied, and no tested theory takes over. In classical general relativity the Big Bang is not an explosion in space and time; it marks the boundary of space and time themselves. Stephen Hawking compared asking what came before it to asking what lies north of the North Pole.

Beyond that boundary there are proposals, and serious physicists stand behind each one: the Hartle-Hawking "no-boundary" universe, eternal inflation with many universes, and "bounce" models in which a previous universe collapsed into ours. None has been confirmed by observation. Even inflation, the leading account of the first instant, has a strong critic in Paul Steinhardt, one of its own founders. On the question "did the universe have a beginning, and why is there anything at all?", honest physics today says: we do not yet know.

Samanvaya: where they meet, and where they do not

Hold the two together and three resemblances appear:

  1. No "then" before the beginning. The hymn opens by denying there was a tadanim, a "then." Classical cosmology describes time itself as beginning with the expansion.
  2. Neither something nor nothing. The hymn sets aside being and non-being. Physics finds that its idea of the vacuum is not "nothing" either, and that its categories stop working at the origin.
  3. An ending in humility. The hymn says even the overseer may not know. Cosmology at its frontier says the same of itself.

And three differences matter just as much:

  1. The hymn offers no measurement, and none of its verses can be tested. Cosmology lives by testing.
  2. Tad ekam is a metaphysical absolute. The singularity is not a "thing" at all; it is the point where our equations stop working.
  3. The rishi reached the wall by contemplation; the physicists reached it by instruments. To merge the two would cheapen both.

So the convergence is a convergence of questions, not of data. And that, to me, is the remarkable part. Three thousand years apart, two disciplined ways of knowing pushed the same question to its limit and gave the same honest reply. The oldest continuous inheritance of Indian thought may not be a doctrine. It may be this temperament: ask the ultimate question, and have the courage to say "we do not fully know."
