How does the earth keep turning,twisting & revolving around the sun without slowing down & making days longer?
I work for a large company that sells & troubleshoot very advanced electronic equipment that is timed from what we call is an earth clock because its my precise that a manmade one & this just blows my mind how its so accurate all these centeries the time has not changed.What do you think?
The earths rotation is slowing and it will eventually stop and become tidally locked to the sun – it’s just that the forces that do this are so small that it takes a very, very long time for this to happen. Thats how we get synchronous binary asteroids not to mention our own moon.
well i think it’s one of the law of physics. anything in motion, stays in motion, unless there’s a force acting on it. and it shouldn’t accelerate unless acted upon. so it doesn’t slow down or pace up, it moves in a constant motion. the only way day or night seems longer, is due to seasons changing, because the earth is tilted on its axis..so some parts will be further or closer to the sun.
The Earth is slowing down. Each day is a few nanoseconds longer than the one before. The tides act as a brake on Earth’s rotation.
Time is measured with atomic clocks nowadays. The standards organizations routinely calibrate Earth’s rotation (there are easily detectable seasonal variations, for example), and occasionally adjust time scales (leap seconds) if they get too far out of sync.
Actually, our rotation does change a little due to tidal drag caused by the moon. They have to insert a “leap second” every couple of years in order to keep precise time.
But things will rotate for inconceivable periods of time because there is nothing to slow them down. Orbits are a little different because there is always a little matter in space which would tend to slow you down, but only after long periods of time, or if you’re in low orbit, not far above the atmosphere.
Earth’s rotation *is* slowing. That’s why leap seconds are periodically added to the length of a day. Earth slows at a rate of 2.2 seconds per 10,000 years, but it’s not due to any “tidal drag” from the moon. It’s due strictly to friction caused by our ocean tides literally sloshing back and forth every day. Long before Earth’s rotation stops our sun will swell into its red giant phase and end all life here.
With the moon slowly pulling away from the Earth, about 1 inch a year, the Earth’s rotation will continue to slow and eventually lead to the planet being locked facing the sun (much like the moon to the Earth). It will take a very long time (most likely billions of years) before the moon breaks away from the Earth’s gravitational pull. Scientists say this is when the Earth will lock with one side constantly facing the sun (if the sun doesn’t go supernova before that point). Maybe if the moon moves too far away from the planet, the scientists of the future will know of a way to pull it back.
Remember 9-1-1, the reason the oceans “slosh” is because of the moon. Tidal drag.
because it never stops it just never ever never stops
Back in 1991-92 at the end of a programme called ‘Tomorrows World’ there was usually a small snippet of information at the bottom of the screen, just under the credits.
One day it read that the Earth was slowing down at the rate of 0.876 of a second per year.
This in itself was of little consequence but I noted it down anyway. The Atomic clock is only accurate to within one second of a year, so this started to make me think about the slowing down of the Earth.
As an ex-army ballistic engineer, I knew that every explosion starts with an implosion, until the force within the implosion is great enough to force the material outwards along a less restrictive flaw, i.e. an open barrel. Once the projectile has left the barrel then gravity starts to take effect and draws the projectile back to earth and it stops. Within a vacuum such as space any great bang theory should carry on for an infinite period of time. However, the gravitational pulls of other bodies will have a marked effect on any projectile, even the Earth and it movement around the sun.
If you are any good at maths, then the rest is quite simple. Multiply the rate of slow down until you have reached the exact amount of time within a single day of 24 hours. By taking this figure even higher, one will quickly realise that the total amount of years from the big bang is 36.5 million years ago. I cannot answer why this is so but it is. This does not say that this is the actual length of time from the big bang but rather the time that it has taken from one simple period of time taken backwards as a progression.
However, this does raise another question, in that if this slowing down is correct and we only take it back even only half the period of 18 million years, then this earth was rotating twice the speed it is today around on its axis and around the sun? If the atomic clock is right today, would it still be right 18 million years ago, or would it have been 4,380 hours fast? 18 million x 0.876 seconds, divided by 60 to make minutes, divided by 60 minutes to make hours = 4,380 hours.
This simple time difference causes another question in that if the decaying rate of atomic material is constant then it cannot be used to date other material, being as the statement of the decaying rate being constant is wrong?
I am baffled by it all but what the heck we live for today and not yesterday and the future?
Best regards.
It is slowing. Clocks like your company’s measure that slowing.
