This episode of Space Time is actually about Spacetime, so pull up a chair, grab your favorite snack, and buckle up, because this episode is going to be a TRIP. Gabe explores what reality is, what "time" is, and why what you think those...

Artist Sarah Sze takes us on a kaleidoscopic journey through her work: immersive installations as tall as buildings, splashed across walls, orbiting through galleries -- blurring the lines between time, memory and space. Explore how we...

We've broken down our preconceived notions about mass and time, now let's redefine what they really are. Since we know that time is not a universal constant, what is? Matt defines causal order and explains how even though time may look...

In the first two lessons of this series on space-time, we've dealt with objects moving at constant speeds, with straight world lines, in space-time. But what happens when you throw gravity into the mix? In this third and final lesson,...

In tough economic times, our exploratory science programs -- from space probes to the LHC -- are first to suffer budget cuts. Brian Cox explains how curiosity-driven science pays for itself, powering innovation and a profound...

There’s a deep connection between gravity and time - gravitational fields seem to slow the pace of time in what we call gravitational time dilation. And today we’ll explore the origin of this effect. And ultimately, we’ll use what we...

In this program, learn all about the space race between the United States and the Soviet Union dating back to the late 1950s and early 60s. Understand the historical context of the time. Contrast that to the current privatization of...

Though close to home, the space immediately around Earth is full of hidden secrets and invisible processes. In a new discovery reported in the journal Nature, scientists working with NASA’s Magnetospheric...

In this video we return to the bass clef and discover a new note, G. There is a new piece to learn and having explored the pitch, the rhythm and the fingering there is another duet to play together. This lesson explores more work in...

NASA is sending the Juno spacecraft to Jupiter, to peer beneath its cloudy surface and explore the giant planet's structure and magnetic field. Juno's twin magnetometers, built at Goddard Space Flight Center, will give...

This video discusses the upcoming mission of the European Space Agency's lunar probe, Smart One, which aims to reexamine the moon using advanced technology and propulsion systems. It highlights the importance of this mission in...

Episode 2: An Unexpected Journey – With five servicing missions, upgraded instruments, and new ways of operating, Hubble is not the same telescope it was when it launched....

In this video, students learn about the importance of measuring objects accurately using rulers. They explore how starting measurements from different points on the ruler can lead to different results. Through examples and comparisons,...

What if the universe is self-aware? Is there a cosmic superconsciousness? Could it be a giant brain? Is the universe a conscious mind? There is a short but lazy answer, and there is longer but more...

One of the most fundamental physics facts is that the speed of light in a vacuum is constant for all observers. But can we really be sure that the speed of light wasn’t different in the past, or perhaps in other parts of the universe? In...

The holographic principle emerged from many subtle clues – clues discovered over decades of theoretical exploration of the universe. Over the past several months on Space Time, we’ve seen those close clues, and we’ve built a the...

Bill Stone, a maverick cave explorer who has plumbed Earth's deepest abysses, discusses his efforts to mine lunar ice for space fuel and to build an autonomous robot for studying Jupiter's moon Europa.

Like sending sensors up into a hurricane, NASA has flown four spacecraft through an invisible maelstrom in space, called magnetic reconnection. Magnetic reconnection is one of the prime drivers of space radiation and so it is a key...

In this lesson, we explored the mathematical relationships between coordinate pairs on a grid system. We learned how to describe the connection between points on a coordinate plane, including the shape of the path that connects them. By...

From the invading, high-tech aliens of ‘War of the Worlds’ to post-world war escapism literature and even real-life scientific exploration today, the stories of Martians have changed throughout time. Find out how we’ve gone from viewing...

Carl Pennypacker at UC Berkeley runs Universe Quest, a summer program supported by the National Science Foundation to engage girls in science exploration. We follow along with a group of Girl Scouts who get to look through a world-class...

Would you take a trip to Mars knowing the risks? What if it were a one way trip? Should we colonize Mars? I took a trip over to the Planetary Society to meet with CEO and Science Guy, Bill Nye to discuss the potential for future human...

Multiple If statements can quickly clutter up a procedure. The Select Case construct offers a convenient alternative. In this lesson, we'll explore the syntax for Select across a variety of examples.
