Tiny discs can levitate in the upper atmosphere using sunlight alone

A physics phenomenon discovered 150 years ago allows tiny objects to levitate using just sunlight – and now it could enable swarms of sensors to explore part of Earth’s long-neglected upper atmosphere

2H2KWEA Big Bang to Present. Stages in the history of the Universe after the Big Bang. At 300, 000 years, matter and radiation decouple, and the Universe becomes transparent for the first time. The first galaxies form at around 300 million years after the Big Bang, but the exact time period is uncertain. At an age of 9 billion years the Solar System formed. Finally, 13.7 billion years after the Big Bang we arrive at the present day. The Universe is still expanding and evolving.

Quantum computers are surprisingly random – but that's a good thing

While randomising a deck of cards gets more difficult as you add more cards, it turns out that the same isn't true for the qubits of quantum computers, which may prove surprisingly useful
