If space travel was instantaneous and you would visit each star of the Andromeda Galaxy for only 1 second it would still take you ~31,000 years to do so.
The 2020 Beirut explosion is estimated to have been equivalent to a few hundred tons of TNT. Hundreds of people died and at least 300,000 were displaced. In comparison, the Tsar Bomba, a Soviet hydrogen bomb, had a blast yield of 50 million tons of TNT. When the Tsar Bomba was tested, the shockwave from its blast circled the globe three times and shattered glass in windows as far as 780 km from the explosion.
The asteroid that killed all dinosaurs — other than the ancestors of birds (yes, birds are dinosaurs) — was traveling 20 to 40 kilometers per second and was at least 10 kilometers wide; a rock larger than Mount Everest traveling faster than a bullet. In its nearly instantaneous descent, it compressed the air below it so violently that it briefly became several times hotter than the surface of the sun. It unleashed the energy of a billion Hiroshimas. Photosynthesis came to a halt, killing most of the plant life, and extinguishing the phytoplankton in the oceans. More than 99.9999 percent of all living organisms on Earth died.
At its most sensitive state, LIGO [The Laser Interferometer Gravitational-Wave Observatory] will be able to detect a change in distance between its mirrors 1/10,000th the width of a proton! This is equivalent to measuring the distance to the nearest star (some 4.2 light-years away) to an accuracy smaller than the width of a human hair.
The loudest sound in the world was so loud that it ruptured eardrums of people 40 miles away, traveled around the world four times, and was clearly heard 3,000 miles away.

More time elapsed BETWEEN the paintings of ice age horses in the Chauvet cave (>33,000 years ago) and the Niaux cave (~15,000 years ago) than has passed since the Niaux cave art and now!
TSMC plans to put a 3 nm semiconductor node into commercial production for 2022. 3 nanometer is as thick as the length your fingernail grows in three seconds.
In 1800, it took over five hour's work to generate one hour of light. Today, an hour of light costs 0.00027 hours or about one second's work.
