The incredable shrinking planet?

In 400 BC the philosopher Plato estimated the circumference of the Earth to be 40,000 miles. In 250 BC Archimedes estimated it to be 30,000 miles. Today it is said to be 24,901 miles around. Has the Earth been getting smaller? If the mass has stayed about the same, but shrinking size has brought us closer to the center of mass, that would explain an increase in the pull of gravity over the eons. That is how dinosaurs 70 million years ago could have grown so large! The cooling of the Earth might have made it inclined to shrink. It makes a lot of sense.

THE MASS INCREASES, THE SIZE HASN'T CHANGED!

How do you know the size hasn't changed?

Gravity pressure at the core can create less volume and more mass. $0% of Sun's mass is at its core. I wonder how that fits in with cores of black holes?? core?? Cores of neutron strars must be very interesting. I have thoughts on just how interesting. TreBert

yeah, dynos ate a lot of it --mostly shrubbish. It was also the relative mean heat of the Dyno period that produces vegan large vegisourus, like Trannysourus Lux or MassaDon.

also precession ( astronomy for slow shifting of back ground stars to our relative fixed vernal point over long periods of time) has been speeding up and so a smaller Earth, as you describe could be the size=rotation=length of sidereal year which would be a new theory.

It is interesting to speculate that if a black hole exists at the center of the Earth, very slowly pulling the Earth into it, you would have exactly the kind of shrinking of the Earth I described!

Such claim is continuously refuted by nature in collisons

E=MC^2 Matter cannot be created nor destroyed.



It can, as not all energy is bound to invariant mass.





Wow. You just overthrew the laws of thermodynamics!

You're like another Bert.



I smell a Nobel!



It is nothing new, it is very old knowledge.

You make perfect sense to me, Poutnik.

Shrinking would tend to speed up the Earth's rotation. But the drag of the Moon tends to slow it down.
