– Could black holes be the key to a quantum theory of gravity? A deeper theory of how reality, of how space and time works? Black holes are interesting because we have a place...
– On February 10th, 2009, somewhere in orbit above Siberia, a Russian military satellite collided with an American communication satellite. At the moment of collision, each satellite was traveling nearly 36,000 kilometers per hour....
(gentle music) (audience applauds) – Thanks Peter. I’m delighted to be here. I first lectured here I think six or seven years ago about the future of space and then did black holes during...
PROFESSOR: Welcome back to A20 special relativity. In this last section of this chapter, we talked about applications and implications of special relativity. We talked about the global positioning system. You all have used...
Over its 9-year mission, NASA’s Kepler Telescope turned its gaze to over half a million stars, revealing that 20-50% of all visible stars could harbor potentially habitable Earth-sized rocky planets. In our relentless search...
Black holes can destroy everything – but can they be destroyed? What happens if we push physics to the absolute limits, maybe even break it and the universe in the process? Let’s create a...
Imagine the vastness of the cosmos revealed in the 1970s, showing us that our galaxy is not just a stationary mass but is moving at an incredible speed of 390 miles per second. This...
– [Narrator] You’ve seen weird, wonderful worlds in science fiction. We don’t yet know what sorts of life might exist out there. But some of the planets not unlike the ones in your favorite...
Black holes are one of the strangest things in existence. They don’t seem to make any sense at all. Where do they come from… …and what happens if you fall into one? Stars are...
Let me take you on an epic journey to the heart of the galaxy. Oh, no wait, that’s uh, that’s just an ice cream sammich. A space ice cream sandwich. I mean, look at...
Let’s talk about space food. In the early days of space exploration, food was mostly squeezed out of tubes and brought up in dehydrated packets. But today we can have quite a variety of...
MARSHA is our proposal for a Martian surface habitat. It’s born of a careful response to the Martian environment and a synergy between structural, architectural and construction principles with human experience at the center....
Right now, you’re looking at renderings of human settlements on Mars. These designs were part of NASA’s 3D Printed Habitat Challenge, a 4-year long competition aimed at engineering homes for another planet. The brightest...
Let’s talk about space food. In the early days of space exploration, food was mostly squeezed out of tubes and brought up in dehydrated packets. But today we can have quite a variety of...
This spacesuit, built in 1974, was reported to cost between $15 million and $22 million. Today, that would be about $150 million. Having not delivered any new mission-ready extravehicular suits since then, NASA is...
This is no ordinary rocket engine. Limited by the technology of their times engineers and physicists have theorized this propulsion method for centuries, but the constraints of time may have just lifted with NASA’s...
