The fleet of microscopic ships can search for the ninth planet as an initial black hole

There are eight planets in our solar system. There are also numerous dwarf planets such as Pluto and Ceres. Although scientists continue to find more dwarf planets, there are some hints that another large planet may be hiding far beyond Neptune. This Ninth planet is considered super-earth – it is about five times the mass of our planet, which makes it about twice as large as the Earth. But, despite several searches for the planet, it has not yet been found. Some scholars suggest that this is generally the original black hole the size of an apple, which can be found using the fleet of spacecraft. This was reported in the journal of astrophysics.

Maybe no one has found the Ninth Planet because it does not exist. The evidence for the planet is not very convincing. This follows from a statistical analysis of the orbits of small bodies in the outer solar system. The idea is that the gravitational pull of the Ninth Planet causes clustering of orbits. But, as others have noted, the observed clustering may be associated with other effects.

If the Ninth Planet exists, it’s a little strange that we did not find it. We have enough sensitive telescopes and other equipment to see a planet of this size. It is possible that the planet is farther than we expect, or has a lower albedo (characteristic of the diffuse reflectivity of the surface). However, there is a much more radical idea. What if the Ninth Planet was not seen because it is not a planet? What if it’s the original black hole?

The original black holes are hypothetical objects that formed in the early moments of the Big Bang. If they existed, they would have the mass of the planet, not the stars. If the Ninth Planet is the original black hole, then it will be the size of an apple. That would make it too small and dark for our modern telescopes. However, it still attracts nearby objects, so there may be other ways to find it.

One way is to send a tiny space probe in the direction of the predicted general direction. A spaceship weighing about 100 grams can be programmed to transmit a regularly synchronized signal. If any of them falls into the range of the black hole, the signals will be expanded by its gravity.

The disadvantage of this approach is that the spacecraft will need to synchronize its signals with the accuracy of an atomic clock, and currently there are no atomic clocks small enough to be mounted on a 100-gram probe. Another team proposed an alternative in which the probes instead send a simple signal, and high-resolution radio telescopes measure the displacement of their trajectories. But the third team claims that effects such as the solar wind will suppress any gravitational effects.
