It all started with Newton’s apple. Or did it? Gravity controls everything from the falling of an apple to the rising of ocean’s tides to the motions of the heavens above. If you’ve ever wondered how this most puzzling force works across our entire universe, you will be delighted by this 24-part course that is accessible to any curious person, regardless of your science education. No other product on the market presents the subject of gravity in as much detail as this course, which will follow the past 400 years of research and experimentation in the field.

Your guide is Professor Schumacher, an award-winning educator, prominent theoretical physicist, and protégé of John Archibald Wheeler, the distinguished gravity theorist who first coined the term “black hole”.

• Explore the intriguing features of gravity, including: why a hammer does not fall faster than a feather (neglecting air resistance, of course!); how astronauts float in space when they are still within reach of Earth’s gravitational pull; and how gravity shapes the four-dimensional fabric of the universe.

• Become immersed in the fascinating study of gravity, experiencing the scientific breakthroughs alongside the great minds of physics: Galileo, Newton, Cavendish, Einstein, Hubble, Hawking, and more.

• Examine a recent discovery: that the expansion of our universe is accelerating due to an as-yet-unexplained cosmic antigravity known as dark energy.

• Delve into the Holy Grail of contemporary physics: the search for a theory that encompasses both gravity, which extends its reach across the cosmos, and quantum mechanics, which governs events at the smallest possible scale.

In Black Holes, Tides, and Curved Spacetime, you will travel to the very edges of modern physics to explore several revolutionary theories and discover that physics is just as exciting today as it was when Newton sat by that fateful apple tree.
