Beyond our solar system

What is beyond space  that we can't see does anyone have any therios is love to hear them thanks hugs

How can the universe be 93 billion light-years across if it is only 13.8 billion years old?

According to the theory of cosmic inflation, the entire universe’s size is at least 10^23 times larger than the size of the observable universe.

Cosmic rays with energies greater than 1 billion electron volts (eV) come to us from beyond our solar system. But because these particles -- electrons, protons and atomic nuclei -- all carry an electrical charge, they veer off course whenever they encounter magnetic fields.

This scrambles their paths and masks their origins. Eta Carinae, located about 7,500 light-years away in the southern constellation of Carina, contains a pair of massive stars whose eccentric orbits bring them unusually close every 5.5 years. The stars contain 90 and 30 times the mass of our Sun.

Thank you for posting this is very interesting hugs
