The light we see from distant galaxies was emitted millions of years ago, and as far as the farthest object we see is concerned, it was emitted 8 billion years ago. So when we observe the universe, we are observing its past.
I have noticed that even those who claim that everything is predestined and we can't change it will look around before crossing the street.
Eternity is a long time, especially for the end.
The fingers can still move and the brain can still think; I have the ideal that I pursue all my life, and I have relatives and friends who love me and love me. By the way, I still have a grateful heart.
Why have we never seen broken cups gather, leave the ground and jump back on the table? The usual explanation is that this violates the second law of thermodynamics, which states that in any closed system, the degree of disorder or entropy always increases with time. In other words, it is a form of Murphy's law: things tend to get worse: a complete cup on the desktop is in a highly orderly state, while a broken cup on the floor is in a disorderly state. It is easy for people to change from a cup on the table to a broken cup on the ground later, not the other way around.

We can go back to the past, but we can't change history after all.
13 Einstein was wrong when he said "God doesn't roll dice". In response to the hints given by black holes, God not only throws a sieve, but also often throws dice out of our sight to confuse us.
14 We created history through observation, not history created us.
Traditionally, these are philosophical questions. But philosophy is dead. Philosophy has not kept up with the development of modern science (especially physics). Scientists have become torchbearers on the road of seeking knowledge and discovering truth.
16 If we have reached the end, the human spirit will wither and die. But I think we will never stop: if we don't go deeper, we will be more complicated. We will always be at the center of expanding possibilities.
17 When I was 2 1 years old, my expectation became zero. From then on, everything became extra pocket money.
18 science is more and more enough to answer questions that used to belong to the religious field, so the scientific statement is complete and theology is unnecessary.
19 god makes both genius and fool, which does not depend on talent, but the result of different personal efforts.
It is undoubtedly a tragedy that life has lost its fun.
