Absence of Moon

Without the moon, a day on earth would only last six to twelve hours.

The moon can appear full, shining like a beacon in the night or just a sliver of a nightlight. Still, it's always there. But what if we didn't have a moon?

Nights would be much, much darker. The next brightest object in the night sky is Venus. But it still wouldn't be enough to light up the sky. A full moon is nearly two thousand times brighter than Venus is at its brightest.

Without the moon, a day on earth would only last six to twelve hours. There could be more than a thousand days in one year! That's because the Earth's rotation slows down over time thanks to the gravitational force or pull of the moon and without it, days would go by in a blink.

Moonless earth would also change the size of ocean tides making them about one-third as high as they are now. Forget about seeing any lunar eclipses or any solar eclipses without the moon, there would be nothing to block the sun.

Without a moon, the tilt of our earth's axis would vary over time. This could create some very wild weather. Right now, thanks to our moon, our axis stays tilted at twenty-three point five degrees. But without the moon, the earth might tilt too far over or hardly tilt at all leading to no seasons or even extreme seasons.

Known as the solar wind, this incessant stream of plasma, or electrified gas, has pelted Earth for more than 4 billion years. Thanks to our planet’s magnetic field, it’s mostly deflected away. Most of Earth is shielded from the solar wind, but right near the poles, in the midday sector, our magnetic field becomes a funnel where the solar wind can get all the way down to the atmosphere. These funnels, known as the polar cusps, can cause some trouble. The influx of solar wind disturbs the atmosphere, disrupting satellites and radio and GPS signals.

The physics of a pendulum wave
⠀
The dance comprises a 60-second cycle, with the longest pendulum completing 51 oscillations and each shorter pendulum having one additional oscillation than the previous.
Consequently, the 15th pendulum, the shortest, completes 65 oscillations. Although the pendulums initially fall out of sync due to their varied oscillation periods, after 60 seconds, they harmoniously return to their starting positions, prepared to repeat the synchronized dance.

Did you know that the moon is slowly moving away from Earth?

It’s true! The moon is drifting about 1.5 inches (3.8 centimeters) farther from Earth every year. So, in the future, it will appear slightly smaller in our sky.
