why not oxygen,gravity and water is present on other planets IF big bang is true?

Question

according to big bang all the planets were the part of a single thing which blasted some time so why only EARTH has gravuty,water and oxygen.

Answer 1

All planets have gravity.

Most planets in our solar system have oxygen on them in some form. Many planets in our solar system also have water on them. Neptune, for example is believed to be wraped in frozen water, and Uranus is believed to have large amounts of frozen water. One of Jupiter's moons, Ganymede, is composed of about 50% frozen water and 50% rock. The differences are related to the way in which the solar system formed and has very little to do with the Big Bang.

There are various concepts of cosmogenic theory (how the solar system formed). One of the more widely accepted ideas is that the solar system formed from a large cloud of gas and matter that coalesced about 4.6 billion years ago, long after the Big Bang took place. This is called the Nebular model.

As the material began to coalesce around the center which became the sun, heavier elements moved toward the center and lighter elements were more likely to remain in the outer part of the new solar system, thus the inner planets like Earth, Venus, Mercury, and Mars have much more heavy elements like iron than the gas giants, like Jupiter and Neptune, which have large quantities of lighter elements like hydrogen, helium, and even oxygen. Most of the oxygen on most planets, including earth, is chemically combined with other elements.

Explaining how atmospheres form around planets is quite complex. Earth's high-oxygen atmosphere is largely the result of biological processes, and earth's gravity is just great enough to retain the atmosphere around the planet. Some sources of primeval atmosphere may have been capture from the original nebula material, outgassing from chemical reactions within the planet, or capture from passing comets. In any case, several of the planets have atmospheres. Venus has an atmosphere composed of about 96% carbon dioxide (which means there is lots of oxygen on Venus), and Mars has an atmosphere high in carbon dioxide.

The extrasolar planet HD 209458b, provisionally nicknamed Osiris, has been found to have oxygen in its atmosphere.

Answer 2

Mars has ice. This means that at one time it had water, oxygen, and an atmosphere. Unfortunately something happened on Mars that wiped out all life on the planet. A planet is a really tricky thing, take Earth for example, even though it can sustain life it still isn't very stable. Yet it's the most stable in our system. As for the rest of your question you should actually read the bid bang theory before you ask about it.

Answer 3

all matter has gravity, the sun, the moon, every single planet in the universe has gravity.
as for oxygen and water there is ice at the poles of mars. and they are pretty sure the is water on one of the moons of Jupiter i think. there are other planets with oxygen and water just not as much as there are without.

Answer 4

All planetary bodies(even asteroids) have gravity. And many do have oxygen, just not in the same concentration(enough to allow us to breathe) as earth. An there are many other planets out there that we cant see or visit yet that may be just like earth, with people just like you asking this same question of other random people.

Answer 5

Other planets in other sun systems might. The Universe is big. How would we know it's not there?
