Letter*

It is said that Einstein had a wish in his later years: "If I can travel through time and space in the future, I hope someone from the future will come to see me before he dies." Who knows, maybe there are people from the future who have actually met the old man. We don't know about it. The unknown is fascinating.

Our present is also the past of future people. The trend of history is unstoppable, and its existence is reasonable. We need to look at the times rationally. Maybe we will never go back to the past or be visited by people from the future, but we must be full of hope for the future, a promising future.

Liu Dada's books are all excellent

I have read excerpts of this book before, but I forgot where I read it. When I saw the excerpt of Qin Xian, I sighed which writer imagined it. I was still very young when I read it, but now that I have grown up, I discovered that it was written by Da Liu. I admire it from the bottom of my heart!

Was this written by Liu to pay tribute to Einstein?

Highly recommended! ! ! ! ! Very beautiful!

He may put himself at the origin of an absolute space-time coordinate. He stands on the bank of the long river of time and watches the rapids of time rolling by. If he is willing, he can go anywhere upstream and downstream.

Einstein said, does mankind still have a future? People from the future traveled through time to comfort him.

Good! Looking at it now, there are still many things that I don't understand. I'll talk about my insights later.

If this is true, then Einstein must be very happy

Very thoughtful and like it very much

Sure enough, humans are the most powerful.

Liu's book is really good

It turned out to be Einstein

It turns out that Einstein liked to play the violin

Da Liu's brain is quite big.

1. Humanity has a future; 2. God does play dice.
