Asteroids represent a serious hazard to Earth, past, present, and future, but will be even more of a concern to humanity as we venture out to space beyond beyond our atmosphere's protection. We will explore what technologies and methods may be available to help protect us from asteroids.

Asteroid Defense (Narration Only)

Nuclear Fission was once hailed as the solution to our power & energy needs, but has grown unpopular of fears of radiation, meltdowns, and radioactive waste. However, advances in science and reactor design may make atomic energy safer and more attractive in the future.

The Future Of Fission (Narration Only)

The genesis and origin of life may require a very rare and delicate mixture of certain chemicals. One of those is phosphorus, and trying to figure out how we ever got enough of it in Earth's primordial soup for life to form in the first place has long puzzled scientists. We will also discuss the recent discovery of Phosphine Gas in Venus's Atmosphere

It's been over half a century since we first went to the Moon, and nearly as long since we last went. To Return to the Moon we need a base with a purpose, and we'll look at what purposes we have in mind and what the bases might be like as we head back to establish a Lunar Colony.

Return To The Moon

Return To The Moon (Narration Only)

Science Fiction delights in showing us grim, dark, giant, and dystopian future cities of covered in garbage and where life is cheap, but how realistic are such metropolises and how can we avoid living in them?

Mega-Cities (Narration Only)

Recently the Military released Navy footage of 3 separate UFO or UAP - unidentified aerial phenomena - we will review that footage and consider both mundane explanations and the not-so-mundane, like secret projects, extraterrestrial origins, and what it might indicate about the technology and motivations of such alien civilizations if they are visitors from out in the galaxy.

Response And Analysis Of Recent UFO Disclosures From The US Military (Narration Only)

We typically imagine interstellar civilizations as vastly superior in technology to modern times, but could the future see planets colonized by spaceships little better than our modern ones? Could some alien worlds allow space travel to develop far sooner and easier than it did on Earth? Or could civilizations abandon more advanced technology?
