think i have a theory.
think a black hole will collide with planet earth in 2012.
a black hole to me is the one element thats used to form a planet and thus create gravity on that planet after its sucked the surrounding materials near it....rocks,sand,dust,gases,water,ice etc.nd planets dont need to be made of solid rock...gases n water would make it look like a round solid lookin planet.but in fact its really a black hole holding these gas or solid matter together!
examples of black hole clumping sand n rocks together:
we have seen black holes having gravity on solid planets with sand n rocks like the earth ,moon or mars...the stronger the gravity......the more bigger the planet it seems.
example of black hole clumping gases together.
jupiter:
Jupiter's upper atmosphere is composed of about 88–92% hydrogen and 8–12% helium by percent volume or fraction of gas molecules. Since a helium atom has about four times as much mass as a hydrogen atom, the composition changes when described as the proportion of mass contributed by different atoms. Thus the atmosphere is approximately 75% hydrogen and 24% helium by mass, with the remaining one percent of the mass consisting of other elements. The interior contains denser materials such that the distribution is roughly 71% hydrogen, 24% helium and 5% other elements by mass. The atmosphere contains trace amounts of methane, water vapor, ammonia, and silicon-based compounds. There are also traces of carbon, ethane, hydrogen sulfide, neon, oxygen, phosphine, and sulfur. The outermost layer of the atmosphere contains crystals of frozen ammonia.[15][16] Through infrared and ultraviolet measurements, trace amounts of benzene and other hydrocarbons have also been found.[17]
Theory of black holes inside a planet before it collecting rocks ,ice ,gases,water ,sand etc from around it.
black holes have the property to attract anything and the more powerful the black hole...the bigger the planet.the less powerful gravity force in a black hole..the smaller the planet and less gravity on it.Compare as below.
Mercury is the smallest planet with the least mass and the least density. The gravity on Mercury is only 38% of the gravity on earth. Considering Mercury only has a radius of 4,879 km, which is barely any larger than the Moon, the gravity is high. The high gravity is due to the high density of the planet.less stronger black hole strength.
Venus is similar in size to the Earth, which is why it is often called Earth’s twin. Its mass, density, and volume are all slightly less than Earth’s. This means that the gravity on Venus is slightly over 90% of the Earth’s gravity. Although you would weigh less on Earth’s twin than you would on Earth, you would not want to visit Venus because of its toxic, burning atmosphere.same black hole strength as planet earth.
Mars has approximately half the diameter of Earth. While Mars is larger and more massive than Mercury, Mercury has a higher density. This results in the two planets having a nearly identical gravitational pull at the surface—
the other planets in solar sytem that are made of gases are not taken intoi account.only solid matter planets are usedin this study.
