How long before the Earth’s heart runs out of fuel? | Science | New

But while scientists can accurately calculate these decomposition rates, they don’t yet understand how essential heat is.

If the Earth’s heat is primarily paramount, this core should probably cool much faster.

However, if heat is created primarily in part due to radioactive decay, the Earth’s heat is likely to last much longer.

But either of these scenarios should not raise an alarm, as estimates of the accelerated cooling of the Earth’s core involve tens of billions of years.

It’s so long that our star will die long before the nucleus, in about five billion years.
