The good news - The universe is finite. Infinite is hard to wrap your mind around.
The bad news - The numbers are huge
The universe has 1022 to 1024 stars 1011 to 1012 galaxies
Our star has 8 planets, one of which is inhabited with an abundance of life including 7 billion people, large mammals. The number of planets and people are the most accurate of these numbers.
A person has about 7 x 1019 cells or 7 x 1027 atoms
And we have the wonders of Quantum Physics. This will keep our curiosity going for a long time.
