Today we will begin our look at the spaceships we might use for colonizing interstellar space in the future. In order to cover the vast distances between even the nearest stars in our galaxy within the boundaries of known physics, we need vessels able to voyage at high speeds for very long periods of time while carrying everything they need to colonize another solar system, a concept typically known as a space ark or generation ship. We will explore the challenges and options for such a vessel, as well as some alternative approaches to the problem.

This episode is the second of a three-part series focusing more on the specifics of colonization including the human aspect of it. Having laid the groundwork last time, we now ask ourselves what the ships carrying people to new worlds would be like, and what life aboard them would be like.

Space is pretty deadly. But is it so deadly that we’re effectively imprisoned in our solar system forever? Many have said so, but a few have actually figured it out.

The prospect of interstellar travel is no longer sci-fi. It COULD be achievable within our lifetime! But, how would an interstellar rocket-ship work? On this week’s episode of Space Time, Matt talks options for interstellar travel — from traditional rocket fuel to antimatter drives, could we travel to other star systems? Watch this episode of Space Time to find out!
“Quantum Entanglement & Spooky Action at a Distance”:
Traveling far distances in space is difficult, but advances in jet propulsion and genetics are making it possible. Trace is joined by Dr. Kiki Sanford to discuss how by altering the genes in our own bodies, we can make ourselves more fit to survive on other planets!

Your Brain In 2050
Posted in computing, neuroscience
At present, our brains are mostly dependent on all the stuff below the neck to turn thought into action. But advances in neuroscience are making it easier than ever to hook machines up to minds. See neuroscientists John Donoghue and Sheila Nirenberg, computer scientist Michel Maharbiz, and psychologist Gary Marcus discuss the cutting edge of brain-machine interactions in “Cells to Silicon: Your Brain in 2050,” part of the Big Ideas series at the 2014 World Science Festival.
This program is part of the Big Ideas Series, made possible with support from the John Templeton Foundation.

Life as a Digital Being

In the future we might see the rise of minds entirely on computers, be it uploaded humans, transhumans, or artificial intelligence. But what would such an existence be like? Would they interact with our world or live in entirely virtual realities or simulated universes?
