Scientists are trying to figure out if time travel is even theoretically possible. If it is, it looks like it would take a whole lot more knowledge and resources than humans have now to do it.
Three scientists won the 2023 Nobel Prize in physics for their work developing methods to shoot laser pulses that only last an attosecond, or a mind-bogglingly tiny fraction of a second.
Some parts of North America will witness a total solar eclipse in April 2024. This may seem far away, but you should think about preparing for this rare and fascinating phenomenon.
In an update of one of the most famous experiments in physics, scientists have used ‘slits in time’ to explore the properties of light and ultrafast optical materials.
Evidence suggests that neither books nor electronic devices are directly to blame for the increase in myopia worldwide. Rather, they enhance this phenomenon by keeping children out of the sunlight.
Life on Earth has dramatically changed the chemistry of the planet. Astronomers will measure light that bounces off distant planets to look for similar clues that they host life.
