Scientists now use new machines to build tunnels under the ground. These tunnels are not for people or cars. They are very small and thin. They are for wires and for the internet. Today, people need the internet every day. We use computers at work and at home. The internet needs long wires to work. These wires go under the streets of our cities. In the past, it was very hard to put these wires in the ground. Workers had to dig big holes. This took a lot of time. It was also very loud and dirty.
Now, there is a new way to do this work. A new machine can dig under the ground very fast. This machine is like a small robot. It moves through the dirt and makes a long path. It does not need to break the street above it. People can drive their cars on the road while the machine works under them. This is very good for big cities because there is no traffic. The robot is very smart and strong. It can go around rocks and other pipes.
After the machine makes the tunnel, workers put the wires inside. These wires carry information to our phones and computers. This tech helps us get faster internet in our homes. It is also cheaper for companies to build these tunnels now. They do not need many workers or big trucks.
Science helps us make our lives better and easier. These small tunnels are a great idea for the future. We can have new wires without making a mess on the streets. Engineers want to make these machines even better. In the future, every city will have these small tunnels under the ground. We will have a fast world because of this new tech.
