Are humans destined to never travel between galaxy clusters?
The current aircraft will fly out of the solar system for 1 light-year radius of more than 17,000 years, while the Milky Way has 200,000 light-years, the local galaxy group has 10 million light-years, and the ultra-local galaxy cluster has 100-200 million light-years.Is it too early?
Everything in the universe is different, what is the most basic substance?

When the sun is going to decline, can humans have the ability to save fuel by adding fuel?
