Einstein was born in 1879, an ordinary Jewish family in Germany. Since childhood, you have shown your talents with your peers, and you are full of enthusiasm and interest in things in the fields of physics and science. He made great achievements in his life, and was even named a great man of the century by Time magazine. Both of them have made great achievements in science.
These two people were born in different times and grew up in different families. It can be said that their life trajectories do not intersect, but they can have many common topics when they meet, because they all have great achievements and attainments in physics. So if these two people meet, they may spark a lot of sparks about scientific theory.
Because of the different birth age, it will also lead to different ideas. Newton was born with Einstein at the earliest, so some of Newton's theories are well known to Einstein. He also worships Newton very much and speaks highly of him. They may talk about many topics, including mechanics, general relativity, physics, mathematics and so on.
When geniuses meet in these two centuries, they will have many common topics. If they do research together, they will certainly bring more power. The powerful collision between two super brains will surely make many amazing discoveries.
