The advantage of being my father's son is that I can see the holes up close, and I can take pictures and videos with my phone.

At the beginning, some of my father's peer experts questioned my father for bringing me to work too much.

But when I said that the archaeology department of Peking University where I applied for 820 points was also in line with what was in front of me, these fellow experts of my father also shut up.

And I started to shoot this hole with my only private rights, and posted it on Sina Weibo.

Over time, I started to have hundreds of followers, and I would spend two days a week with my dad.

I keep track of the holes twice a week, and I can slowly notice that the holes are getting bigger and bigger on my Sina Weibo.

Three years later, in 2046, the hole is large enough for an adult to fall into.

The glass and fence doubled in size as a result, and my fans went from hundreds to millions.

This hole has many names on the Internet, and at first some people said that this hole was a black hole.

I remember that it was my first month in Beijing, and it was the third time my father showed me Kongdong.

At that time, I asked my superiors to throw a small pebble into the hole, because cement had also fallen into it before.

But apparently this request was denied, and we were forbidden to place any items on it.

Dad's idea was very simple, first weigh the stones, and then calculate the speed and time of the stones falling to calculate the specific depth of the hole, but it was clear that Dad thought too much.

The most we can do is reach in and touch it, or observe it with the instrument we have at hand.

The ground around the hole could not be damaged, and the rest of the counterparts seemed to be prepared.

I also took out a searchlight and an infrared lamp to experiment.

But I found that I could only see black holes under the light, and there was no end at all.

The best equipment brought at that time was a professor's R5 type IR emitting diode reinforcement device.

According to the professor, 1,300 meters is not a problem.

But we couldn't see anything after taking the photo, and we only got one parameter that day.

The hole is more than 1,300 meters deep and was posted on Sina Weibo.

After that, there were many comments on my Sina Weibo, and the black hole theory came into being.

Someone started commenting on my Sina Weibo that this is a black hole on Earth, and I went to follow other people who were doing the same thing as me.

Later, I found out that there are people like me on foreign Facebook and various social networking sites.

They all call this type of hole the Earth Black Hole, or EBH.

EBH is the abbreviation of the Earth's black hole: Earth's, Black, Hole (the starting point convention English space is replaced by a ton, you are more inclusive.) ）

Of course, in order to distinguish the region, I will note the region in the future, so my Sina Weibo changed its name to Earth Black Hole ch, and created the Facebook account EBH (ch).

This move has led to accounts around the world that have reported on the Earth's black holes adding me as a friend and creating a global chat forum.

I don't go to this forum very often, because the creator is the Earth black hole of US.

There are clear rules in place for the forum, and all posts are in English.

And I need to go over the wall, so I usually just watch and don't post commonly known as diving.

The advantage of watching these forums is that everywhere will post their understanding of the Earth's black holes on the Internet, and I will collect some of the information and share it with my dad.
