Why is Jupiter so big?
Jupiter and Saturn are the first and second largest planets in the solar system respectively, with Jupiter's average diameter being about 139,822 km and Saturn's average diameter being about 116,464 km. In terms of volume, Jupiter is not much bigger than Saturn, but in terms of mass, Saturn is far less than Jupiter, as Saturn's mass is about 5.6834 x 10^26 kg, while Jupiter's mass is about 1.8982 x 10^27 kg.

Since the universe was born at a singularity
I believe we are all familiar with the "big bang theory of the universe", after all, this is the mainstream theory to explain the origin of the universe, we usually understand the theory that the universe was born in a very small, very dense, extremely high-temperature singularity, about 13.8 billion years ago, this singularity exploded, and then gradually evolved into what we now The universe as we see it now. But the question is, since the universe was born in a singularity, what is outside the singularity?
