The universe is much larger than we thought. Human beings have only touched the tip of the iceberg in the process of exploring the planets and celestial bodies around the earth. Let's take a look at three interesting conjectures that can't be proved at present.

1.Aliens may be using Dyson's sphere to capture black hole energy.

There is an infinite expanse beyond our Milky Way galaxy. We must consider the possibility of the existence of extraterrestrial life in other galaxies, and the probability of the existence of this life is technologically more advanced than ours. There may be a Dyson sphere of extraterrestrial technology.

This theory proposed by Freeman Dyson is a structure around a star. The structure has multiple orbital platforms to capture and redirect the energy emitted from the star, so that our civilization can make better use of the energy of the parent star. We can further start to consider the potential application of these Dyson spheres to collect energy from black holes.

2.Is there a ninth planet lurking at the edge of the solar system?

As we all know, there are eight planets orbiting our sun, excluding Pluto, which lost its qualification as a planet in 2006. However, there is also a lot of evidence that a ninth planet is lurking at the edge of the solar system. This is far beyond the observation range of our earth telescope.

Scientists can only observe and study whether there is a ninth planet that potentially affects the gravitation of other planets, and then make mathematical calculations to find out where it should be and how big it should be according to the strength of gravitation. Although Neptune was discovered when scientists noticed that Uranus was affected by some unknown gravitational force, no other known planet was affected by the gravitational force of this mysterious planet.

3. About wandering supermassive black holes.

Black holes are the most interesting and mysterious element in the universe, and supermassive black holes are the largest and most difficult to understand in this group. These supermassive black holes are almost unimaginable because they are usually billions of times larger than the huge sun. The origin of black holes is an equally mysterious element, which has puzzled scientists for decades.

The only explanation is to speculate that there is a supermassive black hole lurking in the center of each large galaxy, which may be born together with the galaxy itself. Once they are born, they will not remain dormant and will always lurk in the center of the galaxy. In fact, they tend to wander, distort, and absorb in the whole galaxy, ignoring the laws of physics that govern us on earth. Wandering black holes may account for 10% of the mass budget of the whole black hole in the visible universe.
