One of the central predictions of general relativity is that a massive object such as a star, galaxy, or black hole can deflect light passing nearby. This means that light from distant objects can be ...

The solar gravitation lens (SGL) has much potential as a telescope. This point in space, located about 650 AU away from the sun, uses fundamental properties of physics to amplify the light from ...

Solar cells are an increasingly important source of renewable energy, but there’s still room for improvement. Stanford engineers have now developed a pyramid-shaped lens that can focus sunlight from ...

Over the years I've seen concepts of solar-powered sunglasses come and go, but the dream of for some reason wearing solar panels on my face has remained elusive — until today. Genius engineers at ...
