Question

FULL INFORMATION ON BLACK HOLES AND BURMUDA TRIANGLE.

Answer 1

Please read this as another point of view about Venus' retrograde rotation.

Most planets, including Earth, spin in the direct sense: they spin in the same direction as they orbit the Sun (that is, their north rotational pole and north orbital pole point in similar directions, more or less in the direction of the Solar north pole). The exceptions are Venus and Uranus. Uranus rotates nearly on its side relative to its orbit. It has been described as having an axial tilt of 82° and a negative rotation of −17 hours, or, equivalently, of having an axis tilted at 98° and a positive rotation. Since current speculation is that Uranus started off with a typical direct orientation and was knocked on its side by a large impact early in its history, it is most commonly described as having the higher axial tilt and positive rotation. (Since Uranus' moons are considered relative to Uranus itself, their description is unaffected by the choice made for the planet.)

Retrograde Venus, on the other hand, has an axial tilt of less than 3°, and a very slow rotation of 243 days. Perhaps because it is easier to conceive of Venus as rotating slowly backwards than being 'upside down' relative to its near-twin Earth, but also because it is thought that an early massive impact may have resulted in Venus' current rotation while leaving its axis more or less unaffected, Venus is nearly always described as having its axis at 3° and a rotation of −243 days, rather than 177° and +243 days.

Answer 2

well, check these out. I hope youll find them interesting-

1) El Azizia in Libya recorded a temperature of 136 degrees Fahrenheit (57.8 Celsius) on Sept. 13, 1922 -- the hottest ever measured

2) the coldest temperature ever measured on Earth was -129 Fahrenheit (-89 Celsius) at Vostok, Antarctica, on July 21, 1983.

3) Estimates vary, but the USGS says at least 1,000 million grams, or roughly 1,000 tons of material enters the atmosphere every year and makes its way to Earths surface

4) Northridge Mountains in the USA rose in height by 70 cm due to a magnitude 6.9 earthquake on the Richter scale releasing energy equivalent to 2 billion kg of high explosive - equivalent to 100 of the atomic bombs used at Hiroshima.

5) A billion years ago, the Moon was in a tighter orbit, taking just 20 days to go around us and make a month. A day on Earth back then was only 18 hours long. The Moon is still moving away -- about 1.6 inches (4 centimeters) a year. Meanwhile, Earth's rotation is slowing down, lengthening our days. In the distant future, a day will be 960 hours long!

Answer 3

Black holes get formed due to burnt - out stars. Once a star gets exhausted all of the fuel (helium and other gases), they become invisible and posses a greater magnetic force. The magnetic force (or gravitational force) is so high so that, even light does not gets escaped from it.
so, those burnt out stars remain black in colour (since it does not reflects any light). And thus, every star becomes a black whole after its death. The last stage of the star is called as White dwarf, and during its final stages it gives out immense heat.

It is estimated that, our sun reaches its final stage after about 5000 million years and at that time, our solar system would have lost many of its planet due to the immense heat from the sun.

Comming to Bermuda triangle, it is situated in the coast line of Florida, USA. It is really a land mass beneath the ocean (atlantic) having an extremely high gravitational force. This force is strong enough to even pull down a airplane flying over that particular region. Since this extremely high gravitational force is present in a triangle shaped area, this is called as Bermuda triangle.

Its is beleived that, the moon which was once a part of this planet got broken away from this part of the world.

Answer 4

All planets in our Solar System rotate in the same direction except one planet, that is, Venus. This disproves Big Bank theory. If the entire Solar System originated with a Big Bang and all planets came into existence because of an explosion, all planets should be rotating in the same direction. On the contrary, this (rotation of Venus in the opposite direction) is possible only if all the planets were created by an Intelligent Being. The Solar System is existing in very great harmony and not in confusion as the Big bang theory demands.

Answer 5

I'm not sure if I can agree with all your additional comments.. but yes, we're all on Earth... unless theres a new scientific breakthrough connecting the internet to other planets that I havent heard about
