A poem I wrote from someone else’s words
Black Holes Don’t Make a Big Splash
Throughout our universe, tucked inside galaxies far, far away, giant black holes are pairing up and merging. As the massive bodies dance around each other in close embraces, they send out gravitational waves that ripple space and time themselves, even as they pass right through our planet Earth.
Scientists know these waves, predicted by Albert Einstein’s theory of relativity, exist but have yet to directly detect one. In the race to catch the waves, one strategy — called pulsar-timing arrays — has reached a milestone not through detecting any gravitational waves, but in revealing new information about the frequency and strength of black hole mergers.
My research project cum curated installation, Touching Space-Time, exhibited at the University of Glasgow, took the form of what Hawkins calls “art as a ‘lab’ for sensory exploration”(2012:60). That is, in this project I was interested in exploring the notion of art as a laboratory, such that particular sites can become a focus for creative as well as scientific experimentation. Specifically, I wanted to explore the manner in which theoretical and experimental physicists investigate cosmic events that are ‘intangible,’ but that can be translated into sensible forms via various technologies and, moreover, how this investigatory process can itself be translated into creative forms associated with the arts such that diverse, often unpredictable, affects can be generated.
GRAVITATIONAL WAVES — PATTERNS IN SPACE-TIME
A popular (and creative) form of scientific illustration
[Creative, because gravity waves may not actually exist — although the smart money (NSF) is betting that they do.]
Telescopes have been observing waves for a long time. The ones used by past astronomers were designed to make visible light waves more visible. Over time, people came to understand that there was more to the universe than what humans can register with their eyes, and started measuring radio, ultraviolet, and x-ray waves.
Most recently, scientists have turned their attention to measuring gravitational waves."Gravitational telescopes" let scientists observe fluctuations in spacetime itself.
One way of picturing gravitational waves is to imagine the universe as a stretched-out piece of fabric. Planets and stars sitting on the fabric pull it out of shape, and anything placed close to them will fall towards them.
If heavier objects, like stars and black holes, remain still, then the fabric is still as well. On the other hand, if things like neutron stars or black holes are romping around like happy, infinitely-massive puppies, the fabric will dip and ripple around them.
Those ripples in the universe are what scientists call gravitational waves.
