What does a black hole absorb?
After a black hole has formed, it can continue to grow by absorbing mass from its surroundings. By absorbing other stars and merging with other black holes, supermassive black holes of millions of solar masses ( M ☉) may form. There is consensus that supermassive black holes exist in the centers of most galaxies.
What did Einstein say about mercury?
The most brilliant idea. Albert Einstein knew about the problem of the anomalous precision of Mercury when he made a summary of his special relativity in 1907, in which he realized that it could violate a fundamental principle in physics: that bodies fall at the same speed, regardless of their mass and shape.
Can anything survive inside a black hole?
Regardless of the explanation, we do know that it is highly unlikely that anyone entering a black hole would survive. Nothing escapes a black hole. Any trip into a black hole would be one way. The gravity is too strong and you could not go back in space and time to return home.
What happens when a planet is swallowed by a black hole?
Our atmosphere would start to be vacuumed up. And then huge chunks of the Earth would rip apart and follow suit. If Earth managed to fall into the orbit of the black hole, we’d experience tidal heating. The strong uneven gravitational pull on the Earth would continuously deform the planet.
What causes the precession of Mercury?
However, a number of effects in the Solar System cause the perihelia of planets to precess (rotate) around the Sun, or equivalently, cause the major axis to rotate about the center of mass, hence changing its orientation in space….Perihelion precession of Mercury.

Is there a planet between Mercury and the Sun?
The order of the planets in the solar system, starting nearest the sun and working outward is the following: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and then the possible Planet Nine.
How many years does it take for Mercury to orbit the sun?
88 days
Mercury/Orbital period
Orbit and Rotation It speeds around the Sun every 88 days, traveling through space at nearly 29 miles (47 kilometers) per second, faster than any other planet. Mercury spins slowly on its axis and completes one rotation every 59 Earth days.
Can a black hole pull matter from our Solar System?
At the same time, the immense gravity of the black hole would compress you horizontally and stretch you vertically like a noodle, which is why scientists call this phenomenon (no joke) “spaghettification.” Fortunately, this has never happened to anyone — black holes are too far away to pull in any matter from our solar system.
How does the gravity of a black hole affect space?
Matter is heated to millions of degrees as it is pulled toward the black hole, so it glows in X-rays. The immense gravity of black holes also distorts space itself, so it is possible to see the influence of an invisible gravitational pull on stars and other objects.
Is the majority of dark matter made of black holes?
Gravitational lenses are an effect where black holes magnify bright objects behind them. “Our statistical analysis showed that the majority of the dark matter (at least 60 percent) is not made of black holes,” Zumalacárregui said.
What happens when a black hole merges with another black hole?
The Resultant Black Hole is what we call a Binary Black Hole. As the two beasts start to merge, there would appear to be a distorted mess of matter. But, as they come even closer together, the resulting black hole goes through a process known as Ring Down.
