As ripples of energy radiated from the collision of two black holes, a new one — 62 times the mass of our sun — was created. The collision and its waves stunned astrophysicists across the nation and sparked questions across the globe.

The Mary Porter Sesnon Art Gallery held the opening reception for “Black (W)hole” on Oct. 5, an installation designed by the Einstein Collective. The collective is a team of artists, physicists and engineers from Montana State University who collaborated to create an “artscience” piece that allows viewers to interact with and gain a new perspective on the universe.

Black curtains covered a separate room within the gallery next to a sign, requesting people remove their shoes before coming into contact with the piece. Upon entering the darkness through the curtains, a projection of a starfield overlaid with Einstein’s theory of general relativity — which forever changed the field of physics by defining gravity as a property of space and time — appears to be scrawled in chalk throughout the room and onto the viewers.

Students, faculty and the provost of Porter College mingled around the edges of the room, taking in its beauty, while toddlers crawled across the animation’s glowing orb, hypnotized by the swirling colors.

“I know it’s an image on a gallery floor but you approach that blackness, that void […] you actually feel like you might go in it,” said UC Santa Cruz Dean of Arts Division Susan Solt.

The projected design was created by a member of the Einstein Collective and Black (W)hole artist, Sara Mast who was inspired by the equations on Einstein’s blackboard at Princeton. Mast etched these equations using a medium called encaustic paint, where pigments are added to hot wax — in this case oil crayon and panpastel — and then layered onto a surface like wood and molded into a desired shape.

“I’m interested in reaching back to the origins of my self, of humanity […] and the origins of our bodies in the cosmos,” Mast said. “The wax is a bit of a stand in for the body, an idea of the flesh.”

Filmmaker Cynthia Stillwell took stills of the paintings of Einstein’s equations and layered them together, transforming the painting into a digital experience. The equations morphed into a star field and continued this cycle.

“Science solves an equation and then it gets swallowed up by another discovery. It’s a constantly morphing thing,” Mast said. “Thus the morphing shore that moves the viewer in and out of an equation to star field — back to mystery.”

In the center of the room, the galaxy, a 3-D animation on the floor simulated the orbits and collision of two black holes. The smaller “stellar black hole,” still one to 10 times the mass of the sun, disappeared into the larger “supermassive black hole.”

The pink and orange sphere turned into a dizzying neon vortex, exuding bright color as people imagined themselves at the center of the universe. The installation urges people to lose their sense of scale in the dark and “gives a hint of the vastness,” Mast said.

“Being a hyperobject [an object that can be experienced but not touched], we can’t really grasp [black holes] just like climate change,” Mast said. “I’m interested in that idea of making the intangible tangible.”

Rather than feeling diminished by the vastness of the cosmos, Mast feels larger and “enlivened” by her connection to the universe. The installation was designed to let the imagination of the viewer run wild, creating a foothold for people to better comprehend the happenings within it.

“My experience of myself does not have to stop at my skin,” Mast said. “It’s part of my body to go out beyond my skin and out to the stars.”

Although the black hole wasn’t visible in the animation, a white glow that lined the supermassive black hole was present, representing the trace of the orbit around it. This orbiting process is often referred to as extreme mass ratio inspiral (EMRI), and the end result is the stellar black hole merging into and becoming a part of the larger one.

As this process unfolded, a deep hum, like the revving of a motorcycle engine, was broadcast through speakers, an audio representation of the observed gravitational waves. Gravitational waves were radiated at the contact of the collision, ultimately disrupting time and space. Building up to the collision, the orbit of each got smaller and tighter, the speed and volume increasing with it.

In September 2015, gravitational waves were detected for the first time, something scientists have worked toward for decades. Laser Interferometer Gravitational-Wave Observatory (LIGO), the biggest national science foundation project in the U.S. dedicated to detecting cosmic gravitational waves, was caught off guard when their detectors got a loud signal called a chirp — the result of two black holes each roughly 30 times the mass of the sun colliding 1.3 billion light years away.

“Einstein predicted gravitational waves 100 years ago, but he never thought they could be detected,” said astrophysicist Joey Shapiro Key. “We started working on this long before the first detection of gravitational waves, but we did know they were coming up.”

As a member of LIGO, Key explained the broader significance of the discovery and why scientists are so excited about it. The waves can help piece together the history of our galaxy and open up the door to future discoveries. Black holes have existed just as long as our universe and gravitational waves serve as evidence.

“It’s hard to study black holes because they don’t emit light — stuff around them does but not the objects themselves,” Key said. “Gravitational wave astronomy is really our way to discover a bunch of new black holes — how many [black holes] are out there […] what did their lifetimes look like […] this is really just the beginning.”

Key acknowledged the value in understanding the mechanics of the installation but expressed the ability to appreciate it no matter the level of knowledge.

“It really is an art piece though, so you don’t have to know all that background to come enjoy it,” Key said. “You can dig into what’s going on.”
