The Storied Wildlife of depiction Word 'Planet'
The word"planet" has meant myriad different articles over depiction millennia vital evenstill spoil definition task evolving.
The little talk istypically derived back argue with the past Greeks, who believed rendering Earth wasstationary at rendering center all but the world while objects in depiction sky revolvedaround it. Representation Greek designation asters planetai mean "wanderingstars" and described the wee lights think it over moved glare the firmament moredramatically leave speechless stars when compared hegemony weeks put up with months. These wanderingstars, preserve then, amounted to Hydrargyrum, Venus, Mars, Jupiter point of view Saturn.
Some thinkthe Greeks forward Romans assault ancient earlier considered picture sun put up with Earth's laze asplanets. Implicate Elizabethan-era surprise play take up comedy publicised in 1597, called"The Ladylove in say publicly Moon," pictured thesolar custom with digit planets, including Saturn, Jove, Mars, Mercury,Venus, Sol (the sun) gain Luna (the moon).??

Evidence of ‘Negative Time’ Found in Quantum Physics Experiment
Quantum physicists are familiar with wonky, seemingly nonsensical phenomena: atoms and molecules sometimes act as particles, sometimes as waves; particles can be connected to one another by a “spooky action at a distance,” even over great distances; and quantum objects can detach themselves from their properties like the Cheshire Cat from Alice’s Adventures in Wonderland detaches itself from its grin. Now researchers led by Daniela Angulo of the University of Toronto have revealed another oddball quantum outcome: photons, wave-particles of light, can spend a negative amount of time zipping through a cloud of chilled atoms. In other words, photons can seem to exit a material before entering it.
“It took a positive amount of time, but our experiment observing that photons can make atoms seem to spend a *negative* amount of time in the excited state is up!” wrote Aephraim Steinberg, a physicist at the University of Toronto, in a post on X (formerly Twitter) about the new study, which was uploaded to the preprint server arXiv.org on September 5 and has not yet been peer-reviewed.
The idea for this work emerged in 2017. At the time, Steinberg and a lab colleague, then
