But these particles would interact only weakly with ordinary matter, and only via the force of gravity. This description is eerily similar to what we know about dark matter, which does not interact with light yet has a gravitational influence felt everywhere in the universe. This gravitational influence, for instance, is what prevents galaxies from flying apart.

“The main advantage of massive gravitons as dark matter particles is that they only interact gravitationally, hence they can escape attempts to detect their presence,” Cacciapaglia said.

In contrast, other proposed dark matter candidates — such as weakly interacting massive particles, axions and neutrinos — might also be felt by their very subtle interactions with other forces and fields.

In 2006, when TomĂĄs Palacios completed his PhD in electrical and computer engineering at the University of California at Santa Barbara, he was torn between taking a job in academia or industry.

“I wanted to make sure that the new ideas that we were generating could find a path toward society,” says Palacios, the newly tenured Emmanuel E. Landsman Associate Professor of Electrical Engineering and Computer Science at MIT. “In industry, I was sure that would happen; I was not sure how it would work in academia.”

“Conscious processing is overestimated,” lead author Michael Herzog said in a press release. “You should give more weight to the dark, unconscious processing period. You just believe that you are conscious at each moment of time.”

When we ride a bike, Herzog mused, our bodies automatically make minute adjustments to keep from falling over without consciously thinking about it. But even with his team’s two-step model, some of the secondary questions surrounding the ancient debate remain. Questions about how long these discrete moments of consciousness last, or how they differ among people, don’t have answers.

“The question for what consciousness is needed and what can be done without conscious? We have no idea,” Herzog said.
