Turns out the key to making things lighter than air is…light! California scientists think they’ve found a way to make objects levitate using concentrated light — a theory that could even propel ...

Introduction Have you ever wondered how fast a heavy object falls compared with a lighter one? Imagine if you dropped both of them at the same time. Which would hit the ground first? Would it be the ...

If you drop a light object and a heavy object from a tower, which one reaches the ground first? As you may recall from high school physics, this is a trick question. Neglecting air resistance, they ...

Specially designed materials enable objects of different sizes to be levitated and manipulated with light, thanks to new research. Researchers at Caltech have designed a way to levitate and propel ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. If researchers get to know just one thing about a black hole, most ...

Princeton researchers have uncovered new rules governing how objects absorb and emit light, fine-tuning scientists' control over light and boosting research into next-generation solar and optical ...

For several centuries now, scientists have known that light behaves like a wave, expanding out from its source until absorbed or reflected by objects, which are in turn illuminated. In recent years, ...
