WATCH: A Universe in a Nutshell — The Physics of Everything, with Michio Kaku

Professor Michio Kaku delivers a glimpse of where science will take us in the next hundred years, as warp drives, teleportation, and time travel converge with our scientific understanding.

WATCH: A Universe in a Nutshell — The Physics of Everything, with Michio Kaku

The Floating University has docked permanently at Big Think. This is the fourth video in our amazing 12-part series that offers the foundations of a college education in subjects ranging from art history, to finance, to physics, to psychology — all delivered by America's leading thinkers and all for free.


In this 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.

A brief history of human dignity

What is human dignity? Here's a primer, told through 200 years of great essays, lectures, and novels.

  • Human dignity means that each of our lives have an unimpeachable value simply because we are human, and therefore we are deserving of a baseline level of respect.
  • That baseline requires more than the absence of violence, discrimination, and authoritarianism. It means giving individuals the freedom to pursue their own happiness and purpose.
  • We look at incredible writings from the last 200 years that illustrate the push for human dignity in regards to slavery, equality, communism, free speech and education.

Astrophysicists: Gamma-ray jets exceed the speed of light

Scientists find that bursts of gamma rays may exceed the speed of light and cause time-reversibility.

Surprising Science
  • Astrophysicists propose that gamma-ray bursts may exceed the speed of light.
  • The superluminal jets may also be responsible for time-reversibility.
  • The finding doesn't go against Einstein's theory because this effect happens in the jet medium not a vacuum.

Surprising Science
  • A team of physicists carried out experiments to determine the precise value of the fine-structure constant.
  • This pure number describes the strength of the electromagnetic forces between elementary particles.
  • The scientists improved the accuracy of this measurement by 2.5 times.

A new system separates oxygen and hydrogen from Mars’ water

Scientists at Washington University are patenting a new electrolyzer designed for frigid Martian water.

Technology & Innovation
  • Mars explorers will need more oxygen and hydrogen than they can carry to the Red Planet.
  • Martian water may be able to provide these elements, but it is extremely salty water.
  • The new method can pull oxygen and hydrogen for breathing and fuel from Martian brine.
