What Is Dark Matter?
Michio Kaku is a futurist, popularizer of science, and theoretical physicist, as well as a bestselling author and the host of two radio programs. He is the co-founder of string field theory (a branch of string theory), and continues Einstein’s search to unite the four fundamental forces of nature into one unified theory. He holds the Henry Semat Chair and Professorship in theoretical physics and a joint appointment at City College of New York and the Graduate Center of C.U.N.Y. He is also a visiting professor at the Institute for Advanced Study in Princeton and is a Fellow of the American Physical Society.
Kaku launched his Big Think blog, "Dr. Kaku's Universe," in March 2010.
Michio Kaku: Well there is a theory, David, about what dark matter is. You talk about different universes and let’s say that our universe is a sheet of paper. We live our entire life on this sheet of paper, but directly above us there could be a parallel universe, hovering right over us, perhaps inches, centimeters away and objects in this parallel universe would be invisible. Light travels beneath the universe, so we never see this other galaxy. But gravity, gravity goes between universes because gravity is nothing but the bending of space, so if the space between two sheets of paper is bent slightly gravity then moves across.
So think about it. This other galaxy in another universe would be invisible, yet it would have mass. That’s exactly what dark matter is. Dark matter is massive—it has gravity—but it’s invisible. It has no interactions with light or the electromagnetic force, so there is a theory that says that perhaps dark matter is nothing but matter, ordinary matter in another dimension hovering right above us. We should also point out, however, that there are other theories too. Dark matter is the cutting edge of science. Some people think that maybe it is a higher vibration of the string. All the atoms of our body represent the lowest octave of a tiny rubber band vibrating all over our body, and the rubber band could have a higher octave. That next octave could be dark matter. So that’s yet another explanation for what dark matter might be.
So the bottom line is this. There is a shelf full of Nobel Prizes waiting for you, waiting for anyone who can come up with a convincing and experimentally verified explanation of the origin of dark matter.
The answer to this question is at the cutting edge of science, but one theory states that dark matter is nothing but ordinary matter in another dimension hovering right above us.
Giving our solar system a "slap in the face"
- A stream of galactic debris is hurtling at us, pulling dark matter along with it
- It's traveling so quickly it's been described as a hurricane of dark matter
- Scientists are excited to set their particle detectors at the onslffaught
Bernardo Kastrup proposes a new ontology he calls “idealism” built on panpsychism, the idea that everything in the universe contains consciousness. He solves problems with this philosophy by adding a new suggestion: The universal mind has dissociative identity disorder.
There’s a reason they call it the “hard problem.” Consciousness: Where is it? What is it? No one single perspective seems to be able to answer all the questions we have about consciousness. Now Bernardo Kastrup thinks he’s found one. He calls his ontology idealism, and according to idealism, all of us and all we perceive are manifestations of something very much like a cosmic-scale dissociative identity disorder (DID). He suggests there’s an all-encompassing universe-wide consciousness, it has multiple personalities, and we’re them.
Once again, our circadian rhythm points the way.
- Seven individuals were locked inside a windowless, internetless room for 37 days.
- While at rest, they burned 130 more calories at 5 p.m. than at 5 a.m.
- Morning time again shown not to be the best time to eat.
