This is not a contradiction, it is an explainable phenomenon. The reason why the radius of the universe exceeds the age is because the universe has been expanding, and this expansion is only the expansion in space. This is why the radius of the universe is larger than the age of the universe, but this phenomenon does not violate Einstein's theory of relativity.

1. The calculation of the age of the universe is 65.438+038 billion years, which is an internationally recognized result at present.

The age of the universe is 65.438+038 billion years old, which is the result of verification and research by scientists 100 years. The method of measuring the age of the universe is inseparable from an ancient star in the universe, which is called a white dwarf. White dwarfs are the products of burnt-out stars in the universe. Why can white dwarfs be used to infer the age of the universe?

It is because the older the white dwarf, the lower its brightness, which is the product of the early universe. Now, scientists infer the age of the universe from the brightness of white dwarfs. This speculation method must first grasp the brightness of the oldest white dwarf in the universe. In order to get the most accurate results, Hubble telescope and super camera have been exposed for more than two months before shooting the oldest white dwarf star observed so far.

Second, there is a reasonable explanation that the radius of the universe exceeds the age of the universe.

The universe age calculated by white dwarfs is about 65.438+038 billion years old, which is consistent with the universe age and universe expansion rate calculated by various measurement data.

The radius of the universe has reached 46.5 billion light-years by calculation, which is obviously beyond the age of the universe. Did the radius of the universe run out before the birth of the universe? However, this is not the case. The reason why the radius of the universe is larger than the age of the universe is because the universe is expanding.

The expansion of the universe has no center, and the expansion of the universe is just an expansion of space. The stars in this expanding space will not expand, but the distance between stars will change because of the expansion of the universe.

This is also in line with Einstein's theory of relativity. As long as the distance between objects is far enough, the faster the expansion, the larger the radius. In this way, the radius of the universe will definitely be larger than the age of the universe, because the universe has obviously accelerated its expansion speed because of the existence of dark energy.
