“It is this, and the existence of limits.”
When Einstein radicalized science with his general theory of relativity, the fulcrum of which shifted our understanding of reality more profoundly than anything since the Copernican reordering of the universe, he had made several daring leaps of the informed imagination to demonstrate that space and time are interwoven into a single entity — the foundational fabric of the universe — and that both are not static absolutes, as it was believed for millennia, but dynamical quantities responsive to the energy and matter in the universe.
But Einstein’s boldest leap remains obscured by his theory’s name. At a time when other scientists believed that the speed of light was variable, Einstein took it as a fixed limit of nature and made it the absolute non-negotiable around which all other variables and parameters enfolded. Only in doing so — against every common-sense intuition — was he able to arrive at the relative nature of space and time, from which followed other previously unfathomed revelations: that gravity is a force caused by spacetime, that the universe is expanding, that black holes exist, that time ends in a singularity. Relativity was thus built upon this one absolute — a supreme testament to the generative power of limits, of deliberate constraints as a catalyst for creative breakthrough, consonant with Kierkegaard’s insistence that “the more a person limits himself, the more resourceful he becomes.”
That is what the Canadian astronomer, poet, and tragic genius Rebecca Elson (January 2, 1960–May 19, 1999) celebrates in a spare, stunning poem titled “Explaining Relativity,” found in her sole poetry collection, A Responsibility to Awe (public library). Elson — who made major contributions to the understanding of galaxy formation, dark matter, and how stars are born, live, and die — died at only thirty-nine, leaving behind fifty-six scientific papers and this one slender, splendid book of poetry.
At the third annual Universe in Verse, theoretical cosmologist and jazz saxophonist Stephon Alexander — who belongs to Elson’s rare species of genius with immense scientific talent paralleled by a commensurate talent in an art — brought the poem to life, with a lovely prefatory reflection on his own improbable path, from the black magic tradition of his Aruban high priestess grandmother to his dual calling as a scientist and an artist.
by Rebecca Elson
Forget the clatter of ballistics,
The monologue of falling stones,
The sharp vectors
And the stiff numbered grids.
It’s so much more a thing of pliancy, persuasion,
Where space might cup itself around a planet
Like your palm around a stone,
Where you, yourself the planet,
Caught up in some geodesic dream,
Might wake to feel it enfold your weight
And know there is, in fact, no falling.
It is this, and the existence of limits.
