How was earth made, scientifically?

Question

I know that no one really knows that answer unless you were there, but your opiniions would help with my daughter with her curiosity/essay.

Answer 1

Big Bang Theory :)
The Big Bang is the cosmological model of the universe whose primary assertion is that the universe has expanded into its current state from a primordial condition of enormous density and temperature. The term is also used in a narrower sense to describe the fundamental "fireball" that erupted at or close to an initial time-point in the history of our observed spacetime.[1]

Theoretical support for the Big Bang comes from mathematical models, called Friedmann models. These models show that a Big Bang is consistent with general relativity and with the cosmological principle, which states that the properties of the universe should be independent of position or orientation.

Answer 2

Scientifically, per your request....

The sun was a spinning ball of fire and flame and in the instant of the big bang it spewed out masses of matter that by laws of physics and trajectory continued to spin around the sun and they began to cool. They soon cooled, and since they were spinning they spewed out tiny masses and they cooled, and they became planets with moons. And one planet was placed just the right spot that if any farther away from the sun it would be too cold and any closer too hot to sustain life.
Now on this cooled body of matter, miniture life forms in the oceans swam together still spinning from the earth spinning and they formed together to make a life form that climbed out of the water, evolved to having legs.. And more life forms climbed out and grew legs, and these life forms mated, though they dont know why. And from them human life was born. And from the same marine life forms, as many as they were, DIFFERENT life forms emerged and spoke different and believed different. And moved to different parts of the earth cause they knew they were different, though they came from the same life forms as other different beings.

Yes that is the scientific way.....though no one can ever explain where the original matter came from. Nor can they explain how a non thinking single cell marine life form can evolve into a human. Nor the fact if we came from apes, where did the apes come from and if we are done evolving why are apes still here?

The fact that the Lord "spoke" the world into existance, and "spoke" life upon the planet, and from His Holy being came our intelligence sounds more plausible and believable, and that is the way I believe.

Answer 3

Hi. A star exploded and its contents spread out for a large distance. Eventually some of these contents mixed with stuff from other exploded stars and formed a very large gas cloud. This cloud collapsed under gravity and formed a spinning disk which further collapsed, forming into the Sun and surrounding planets.

Answer 4

Oh dear.

Really, an awful lot is known about star and planet formation, a whole library's worth of books and scientific articles, but given the answers above, this knowledge seems not to have percolated to most of the public yet.

The solar system is part of a galaxy, the Milky Way. The Milky Way has lots of stars, but about 10% of the mass is interstellar gas and dust. Most of this material has been inside stars, been processed, and then ejected into the interstellar medium by supernovae or planetary nebulae. Most of the material has been inside stars several times. Under the influence of the dynamics of the Galaxy as a whole, the interstellar medium sometimes accumulates into relatively dense clouds containing hundreds of thousands of solar masses of material. These clouds are quite cold (10 or 20 degrees above absolute zero) and the gas within them is mostly molecular, predominantly molecular hydrogen. Within the clouds, magnetohydrodynamic processes sometimes create even denser "cores" that are gravitationally unstable. The cores contract under their own gravity. As the core becomes denser, it fragments, and the fragments begin to spin fairly rapidly in order to conserve angular momentum (ice skater spins faster when she brings in her arms...). The mass of the fragments is around one solar mass, sometimes more, sometimes less. The spinning fragments become "protostellar nebulae", and contract into a dense, rotating disk of gas, about the size of a solar system, with a dense protostar in the center. Friction in this disk causes material to move inward, feeding material into the protostar. The disk becomes thinner and denser at its mid-plane. Eventually, it reaches a sufficient density that the dust grains begin to stick together to form lumps up to a meter or so in size. These collide, sometimes stick, and become planetoids. The planetoids then can grow rapidly, because they attract additional material by their increasing gravity. Planetoids collide and grow. Eventually, the protostar gains enough mass to begin burning as a star, and this usually blows all the remaining gas and dust out of the center of the new solar system. The planets continue to collide, until all the planets on unstable orbits are gone. The result is a solar system with a central star and planets. These processes have been observed in numerous young star systems.

Answer 5

The Sun, Earth and all the other planets and asteroids within our Solar System were made from the dust left after a massive star explosion. First the Sun took shape and due to the massive gravitational pull it created a disc of matter around it from which the planets were born.Small particles joined forming balls of condense matter and asteroids...and after millions of years of violent colisions between them planets were shaped.

Answer 6

Everything was all together. Then there was a Big Bang and evertything started blowing apart. And part of what blew apart eventually became the earth.

Answer 7

the correct question is-
how did earth come in to existance ?
it woul be difficult for you to understand, so for get explaining it to your daughter. for this you have to first understand the formation of universe. and then so on and so forth.

Answer 8

The "Big Bang" created rocks which after millions of years started merging together and after years of this they created plants or the "Big Bang" created large rocks which then became plants. (you can also google this for more accurate results)

Answer 9

according to all the science books... there was a time when there was nothing. then chaos happened and the earth "supposedly" came into existence. but my beliefs... and according to the bible...

GOD created the world. this is the only legitimate explanation.

someone please tell me how something is created out of nothing. that's pretty lame stuff. i'm also surprised her school is having her write an essay on this subject. tisk tisk...

Answer 10

its the accumulation of left over debris from the birth of the solar system
