Danish scientists have come to the conclusion that the Earth’s core is 2.5 years younger than the crust.
Researchers at Aarhus and Copenhagen universities have determined the difference in age between the center of the Earth and its mantle, which arose under the influence of gravity.
According to the Daily Mail, according to Einstein’s theory of relativity, the gravitational potential affects time: near a massive object, time will go slower.
For example, GPS and GLONASS satellites exist in different time frames. For them, time flows in different ways, but in this case we are talking about fractions of a second.
For the first time this theory of Einstein when calculating the age of the core of our planet in 1960 was used by physicist Richard Feynma. He calculated that the difference in age between the center of our planet and its mantle is from one to two days, but Danish experts checked his calculations and found an error.
Ulrik Uggerhei and his colleagues found that with the existing density of the Earth’s core, the difference in the time of its formation differs from the time on the crust, taking into account the distance from the center to the surface, by several years.
According to the calculations of specialists, the stretch in time is 3 × 10-10, and each second in the center of the Earth is counted slower than on the surface. Our planet has been around for about 4 billion years, so the cumulative stretching effect added a difference of 1 to 2.5 years.
Using the same principle, a team of Danish scientists calculated that the center of the Sun is about 40 thousand years younger than its surface.
Like a comment. That is, the core of the Earth lagged behind its surface in its movement in time, and, of course, on the way for 1-2.5 years. And the Sun’s core remains in the past, in what was 40 thousand years ago, but in space it remained somewhere on the edge of the Galaxy! It is catching up with us being .12 million kilometers behind us.
