Hey Bill Nye! What If the Earth Were a Cube Instead of a Ball?

Understanding the shape of the Earth is all about its mass, says Bill Nye the Science Guy. If it weren't for all the water, rocks, metals, and lava on our planet, it might have an irregular form.

Life on Earth Thrives Thanks to the Same System Driving Climate Change

Nature is a delicate balancing act, says Bill Nye the Science Guy. It's important we understand that the same system making Earth warm enough to live on is also driving climate change.

Bill Nye Explains How Evolution Gave Us the Golden Rule

Charlie comes to Bill with a question about the balance between the ethics of scientific concepts and those scientific concepts in and of themselves. In response, the Science Guy demonstrates how the two ideas — an idea and its ethical implications — are innately inseparable.

In today's #TuesdaysWithBill, Charlie comes to Bill with a question about the balance between the ethics of scientific concepts and those same scientific concepts in and of themselves. In response, the Science Guy demonstrates how the two ideas — an idea and its ethical implications — are innately inseparable. Bill also delves into a popular thought experiment involving a burning building: If you could only save one person, who would you save: your child or your grandchild? The correct answer makes ethical and biological sense for the same reason, and Bill explains why.

Hey Bill Nye! What's the Evolutionary Advantage of Grandparents?

Today's #TuesdaysWithBill answer serves as affirmation to grandparents everywhere.

There are many species on Earth whose lifespans extend only long enough for each individual to do their part in propagation. Why, then, have humans developed over the years to live well beyond our reproductive years? According to Bill Nye, our ever-expanding longevity can be attributed to the remarkable usefulness of tribal elders: patriarchs, matriarchs, grandparents, and mentors. We've evolved to live beyond our reproductive years because, as the saying goes, it takes a village.

Diamond Jackson from Corpus Christi, Texas, asks Bill all about the evolutionary backstory behind infatuation. Why do we fall in "love" at first sight? The Science Guy presents the idea that we're still physically conditioned to want to pass on our genetic material as quickly as possible. Thus, infatuation is a leftover facet of old caveman living when predators roamed everywhere, threatening your genetic line. So infatuation was (and continues to be) a tool for encouraging folks to get busy.
