Many people are fascinated by the Universe. Mainly because it’s not explored enough and we are always wondering about the life outside the Earth. But, space has so many anomalies we haven’t tacked so far. Even though they have been familiar for centuries, we still don’t have the technology to reach long distances and to explore the space further. One of those anomalies is a black hole. We have heard about them, but we don’t know much about black holes. People tend to overestimate their power thinking they are a distant threat, even though, a black hole has the power to swallow the entire planet.
One of the biggest misconceptions is that black holes destroy everything in their radius. But, they are stationary, which means they don’t move. Considering they are invisible, scientists use two methods to see them. They can monitor the planets and gases around a black hole, to see if you are orbiting a hidden object. Another way is a bit complicated and includes radio waves and x-rays. When gas enters a black hole, it heats up to extreme temperature and emits radio waves and x-rays. Even if we can’t see a black hole, we know its exact location.
So far, no black hole has been detected in our galaxy, so we are safe. But, to avoid further speculations, scientists from the Princeton University found a way to prevent future alarms. They conducted a series of investigations and simulations of what would happen if a billion-ton black hole struck the Earth. They used real-time data, and estimated speed is a few hundred kilometers per second. But, it’s power will be smaller than an atomic nucleus and it this case, it will make a small, needle-like tunnel through the Earth.
Regardless of the size, we would still experience its effects because the black hole first reaches and then exits the Earth’s outer core. In this case, the outer core will vibrate, creating shock waves. This would trigger all seismic detectors on our planet, something similar to an earthquake, but on a global level. Luckily, the effects will be minor, and they will not create global destruction because the shaking will be around magnitude four. These events are extremely rare, so there is no reason for panic. And even if they happen, it will be once in every ten million years.
