In 1797, English scientist Henry Cavendish measured the strength of gravity with a contraption made of lead spheres, wooden rods and wire. In the 21st century, scientists are doing something very ...
Tracking time is one of those things that seems easy, until you really start to get into the details of what time actually is. We define a second as 9,192,631,770 oscillations of a cesium atom.
A common theme in science-fiction media, time travel is captivating. It’s defined by the late philosopher David Lewis in his essay “The Paradoxes of Time Travel” as “[involving] a discrepancy between ...
The flow of time isn’t as consistent as we might think – gravity slows it down, so clocks on the surface of Earth tick slower than those in space. Now researchers have measured time passing at ...
There are a million theories about the human species and how we interact with the earth. Quantum physics is the study of matter and energy. It discovers what the building blocks of nature are. Many ...
Philosophical Transactions: Mathematical, Physical and Engineering Sciences, Vol. 373, No. 2049, Theo Murphy meeting issue: Spatial transformations: from fundamentals to applications (28 August 2015), ...
Your location in this Universe isn't just described by spatial coordinates (where), but also by a time coordinate (when). It is impossible to move from one spatial location to another without also ...
A time warp can be thought of as anything that disrupts the flow of time by making it go faster or slower. While the idea may seem fantastical, time warps were predicted by Albert Einstein's ...
Time seems to have ticked more slowly when the universe was young, according to observations of ancient astronomical objects that appear to evolve at a fifth of the rate we see today. The idea that ...
