About this episode
Energy powers our entire universe, whether it’s light from a star or energy stored in the food we eat. But could we ever run out? Will there be a time, far in the future, when the last drop of energy is used up? We asked physicist Dr. Kiley Kennedy to help us find the answer. Got a question that’s draining your mental battery ? Send it to us at BrainsOn.org/contact and we’ll find the answer for you, because knowledge is power ! See omnystudio.com/listener for privacy information.
