Normal maps are useless inside black holes. At the event horizon — the ultimate point of no return as you approach a black hole — time and space themselves change their character. We need new coordinate systems to trace paths into the black hole interior. But the maps we draw using those coordinates reveal something unexpected — they don’t simply end inside the black hole, but continue beyond. In these maps, black holes become wormholes, and new universes lie on the other side.

What if there was a museum that contained every type of life form in the universe? This experience takes you on a tour through the possible forms alien life might take, from the eerily familiar to the utterly exotic, ranging from the inside of the Earth to the most hostile corners of the universe.
New research is upending our idea of life and where it could be hiding: not just on Earth-like planets, where beings could mimic what our planet has produced, but in far flung places like the hearts of dead stars and the rings of gas giant planets. Nowhere in the universe is off limits.
Only when we know what else is out there will we truly know ourselves. This thought experiment will give us a glimpse into what could be out there, how we might find it, and just how far nature’s imagination might stretch.

OVERVIEW:
In a profoundly informative and deeply optimistic discussion, Professor Michio Kaku delivers a glimpse of where science will take us in the next hundred years, as warp drives, teleportation, inter-dimensional wormholes, and even time travel converge with our scientific understanding of physical reality. While firing up our imaginations about the future, he also presents a succinct history of physics to the present.

MICHIO KAKU:
Dr. Michio Kaku is the co-founder of string field theory, and is one of the most widely recognized scientists in the world today. He has written 4 New York Times Best Sellers, is the science correspondent for CBS This Morning and has hosted numerous science specials for BBC-TV, the Discovery/Science Channel. His radio show broadcasts to 100 radio stations every week. Dr. Kaku holds the Henry Semat Chair and Professorship in theoretical physics at the City College of New York (CUNY), where he has taught for over 25 years. He has also been a visiting professor at the Institute for Advanced Study as well as New York University (NYU).
— TRANSCRIPT:
My name is Professor Michio Kaku. I’m a professor of theoretical physics at the City University of New York and I specialize in something called string theory. I’m a physicist.
Some people ask me the question, “What has physics done for me lately? I mean, do I get better color television, do I get better internet reception with physics?” And the answer is yes. You see, physics is at the very foundation of matter and energy. We physicists invented the laser beam, we invented the transistor. We helped to create the first computer. We helped to construct the internet. We wrote the World Wide Web. In addition, we also helped to invent television, radio, radar, microwaves, not to mention MRI scans, PET scans, x-rays. In other words, almost everything you see in your living room, almost everything you see in a modern hospital, at some point or other, can be traced to a physicist.
Now, I got interested in physics when I was a child. When I was a child of eight, something happened to me that changed my life and I wanted to be part of this grand search for a theory of everything. When I was eight, a great scientist had just died. I still remember my elementary school teacher coming into the…

Supernovas are the dramatic death of giant stars. Their explosions outshine all the stars in a galaxy, and the last minutes of their life are the most energetic and the most cataclysmic events that we see in the universe.
