Qianfanggong is in the four mountains, the four mountains are in the earth, the earth is in the solar system, the solar system is in the Milky Way, and the Milky Way is in the universe.

Ma Cha went to Qianfang Palace for three consecutive days to get together with Ziyun, and they had a great time together. Back at the Miracle House, Masha sets out to do some urgent work. The first time he went to Qianfang Palace, he took his little brother with him, and the next few times he went to Qianfang Palace, Ma Cha went alone.

Ma Cha has already placed the little brother, and the little brother can learn some spells from the spell master every day, and he can also read a few books given by Ma Cha to understand the magic of the magic weapon. It can be said that the younger brother lived a full and happy life.

Ma Cha sat at the small table by the window in the miracle house, and he looked out the window at the deep night sky, so many stars, like floating lights at night. There is a toy, with a thin cover on top and a small tray on the bottom, in which a combustible substance is placed, and when it is lit, the floating lamp floats higher and higher. This floating lamp is forced to rise, and the stars in the night sky must also be affected by some force, which creates their current situation.

The stars in the sky are articles written by the universe, the night sky is paper, and the stars are words, how beautiful is this.

Stars are light, and there are planets and stars in them. In addition to the study of mechanics, we should also study light, and optics leads people into the world of light and allows people to explore the mystery of light.

Ma Cha's astronomical telescope was placed next to the small table, and it watched the night sky. Ma Cha's astronomical telescope is his magic weapon for observing the night sky, and this magic weapon is sold in his magic weapon store.

For a long time, people only used their eyes to observe the universe, and when they saw the moon and the sun, they saw the sun and the sun, so the gods flew all over the sky. This is, of course, an incorrect view of nature.

When people observe the sky with magic weapons, they can see farther into space. Because people can't fly without wings, they can't fly to high altitudes to observe, and even if they go up to the mountains to observe space, they still can't see far enough. It is quite possible that in the early days people did not know the sky as well as a bird, and the eagles already knew what people knew at first.

Launching a probe is an advancement, people can't go up, let the machine go up and take a look, send back precious pictures. In the past, there was a demon domain on the earth, and the demon domain was a red space. Beyond the earth, there is also a red space, where it looks like rusty iron everywhere, and it is difficult to see life. It is said that the Tianyi Star people were inspired by this red space and created an even more terrifying red space on the earth, which was called the Demon Domain. The sun seen in the red space outside the earth is blue, and the same is true in the demon realm.

Ma Cha thinks of the Demon Domain, creepy. Maybe there are places in the universe that resemble demonic domains, and where they are, people can't see them for the time being. At present, most of the research on the universe relies on observation, using various possible methods to make observations, and then analyzing the observation data to draw conclusions.

But people still can't find the Demon Domain in the universe, the universe is too big, the Demon Domain is very secret, and the Demon Domain in the universe is in an unknown place.

Ma Cha has been thinking about astronomy, force, and light, these mysterious things attract Ma Cha to explore, he has not yet made new discoveries, but he believes that there will be new discoveries in the future.

Man's exploration of the universe is endless, Ma Cha has fallen in love with the universe, and he is always in pursuit of the precious truth. Sitting in the miracle house, Ma Cha thought about the speed of light, someone once said that when an object travels at a speed approaching the speed of light, time slows down, an object travels at a speed equal to the speed of light, time stops, and the object travels faster than the speed of light, and time flows backwards.

Ma Cha held a cup of hot coffee in his hand and fell into deep thought, and the question he pondered seemed interesting.
