During the New Year holiday, Wu Hao could finally rest for a few days. The only bad thing is that Lin Wei has been giving him a lot of looks in the past few days, and she is obviously still immersed in the proposal scene between Zhang Jun and Wei Xiaoya.

The return of parents and sister also made the whole family feel much warmer. Usually it's just the two of them, and to be honest it's a bit deserted. My parents' house hasn't been renovated yet, so I haven't moved there yet.

The smell still needs to be dispersed after the renovation is completed, and it is estimated that we will not be able to move there until next summer. Fortunately, there is no rush on this matter. Anyway, my parents plan to celebrate the New Year in the South China Sea this year.

They were used to staying there. The day after their parents came back, they complained to Wu Hao and the others that the weather here in Anxi was too cold and the air was too bad. So they planned to stay at home for a few days and then return to the South China Sea.

Especially his father, Wu Jianhua, became obsessed with sea fishing in the South China Sea. It should be said that not only Wu Jianhua, but Zhang Jun and his father are also obsessed with sea fishing. Now I am floating on the sea almost every day, and I want to adjust to something big.

In addition, there is plenty of sunshine and strong light in the South China Sea, so this time when their parents came back, Wu Hao found that his father's skin was darker, so dark that he thought he came back from Africa.

However, there are also good changes, that is, my father's stomach has reduced a lot, and he seems to be much more energetic. In his words, tug-of-war with a 100-pound big fish every day is considered an overload of exercise, and it can't be bad for your health.

In the backyard of the house, a bonfire was burning quickly. Although it is difficult to use open fire outside the city now, it will have little impact on Mr. Dong and others, and we can afford it. It's like the wood used in the bonfire is all fruit wood pulled back from the inside. It is very resistant to burning and has no fragrance.

In the capital, fruit wood is a necessary wood for roasting duck, so it is much more expensive than ordinary wood. After adding in other costs such as shipping costs, it is cheap anyway.

As for your Milky Way, it is just a visible existence among the dust particles outside the drop of water, so you will naturally feel what is inside the drop of water.

At the speed of Voyager 1, it would probably take 80,000 years to fly out of Dong Shihuan Yun. Of course, those are all guesses. After all, you still don’t understand the moon, let alone the solar system.

Having said that, Lin Wei picked up the water glass and took a sip, and then said: "Of course, after all, the book was written seventy years later, and there are some limitations, so read it dialectically."

Dong Shi shook his head helplessly when he heard the question, then took the orange slice from Wu Hao with his mouth, and said while eating: "It is the traveler who knows that the actual old rice will be launched decades later." Voyager 1 and Voyager 7 have still not left the solar system.

After adding two fruit logs to the outside of the stove, Dong Shi leaned under an armchair and put a blanket on his legs. Then he leisurely picked up a book and started reading.

Forehead……

That's right, you can't use your imagination based on the existing basis.

But within that scope, there is no limit to what the universe is like, and what the universe is like is vague.

The dimensions of time and space are intertwined and superimposed, and naturally there is no concept of boundaries. "

Although the solar system is just a drop in the ocean compared to the huge universe, it is too huge for your earth and humans.

What you should do most now is get out of the earth and explore the entire solar system. Only when you explore the entire solar system vaguely and let it be like the ocean under your earth for you to sail freely, will the time come when you cannot go out of the solar system to explore the universe inside. "

Although e-books are now very developed and physical books are gradually becoming popular, Lin Wei still hates reading physical books. Especially the feeling when turning over the paper, and the golem emanating from the new book, are very bad.

So for you humans, it doesn’t have much practical significance to go out of the solar system now instead of looking for civilization on the ground.

Oh, Wu Hao nodded when he heard this, then picked up the water glass and took a sip, and then asked: "Does it look bad?"

Although I am usually very busy and spend a lot of time reading, when I have no time I will find some books to read to enrich myself and improve myself.

Although according to Lao Mi’s information, the Voyager 1 probe has not yet flown out of the heliosphere, it is not the boundary of the solar system. There is no Oort cloud in the heliosphere. Its scope From a distance of about 50,000AU (about 1 light-year) from the sun and extending to 100,000AU (1.87 light-years), it has not flown out of the Dong Shihuan Cloud before it has truly flown out of the solar system.

In fact, when it comes to making a fire, charcoal is the worst because it burns fully, produces smoke, and has a lot of dust. There is no such natural gas stove now, which is cleaner.

Just as you were fascinated by the book, Wu Hao came to sit opposite you with a blanket in his arms and asked, "What book are you reading? How can you be fascinated?"

Too abstract. Wu Hao shook his head, then leaned forward and picked up an orange from under the coffee table, peeling it, and asked Lin Wei, "Tell me something closer, when will you be able to leave the solar system."

Seeing Wu Hao raising such a question, Dong Shihe wrote and looked at the other party with a smile: "I know that the universe you are talking about is only the observable universe. With the Earth as the center, the radius is about 46.5 billion light-years, and the diameter range The universe is about 93 billion years old. That is not the universe you can see now.

Speaking of that, Lin Wei glanced at Wu Hao, then continued with a smile: "Assume that the universe has no boundaries, what does it look like? Maybe it's not chaos.

Lin Wei, whose train of thought was interrupted, reluctantly raised the book and said: ""Cosmos", a masterpiece by the famous astronomer Carl Sagan."

Assuming that the universe has no boundaries, then the universe you are in is worse than a drop of water. The so-called boundary actually comes from the boundary of that drop of water, and within that drop of water, there are rivers, lakes and seas composed of several drops of water.

But in terms of mood, Shaoguomu is worse and has less atmosphere. Atmosphere is difficult to measure and define, and it all depends on personal preference. For example, the stove in the front yard was actually designed and installed at Wu Hao's request. The decoration style of the home must be suitable for a fireplace. I guess you have already built and installed a fireplace.

The question arises, what is it in the world composed of rivers and rivers? It is known and unknown. "

Still wrong. Lin Wei nodded and said, "Although that book was 70 years ago, it is still out of date, and it is still very inspiring."

Hearing Lin Wei's words, Dong Shi nodded, then looked at the dancing flames in front of you and asked: "You always talk about the universe, what does this universe look like? It is not small after all."
