I'M Sorry For This Question'''The Big Bang'?

Question

Light Energy Comes from this point of light-some time late 3.6 billion years or so'we set on earth and see light come from a long distance in space--shouldnt the light be past our planet by now????or was earth here bfore the big bang-??

Answer 1

i don't know what you are asking.

the big bang seems to have occurred about 13 700 000 000 (13.7 billion) years ago. about 380 000 (380 thousand) years later, the universe expanded and cooled enough that free electrons could combine with atomic nuclei to form atoms. at that time the universe was about 76 percent hydrogen and 24 percent helium. light could then pass thru the universe unscattered so the universe became transparent. today, we observe this light stretched to microwave wavelengths and call it the cosmic microwave background. we observe the cmb in every direction we look, but the universe was much, much smaller then than it is now. since the big bang was the entire universe and everywhere in the universe was once the big bang, the only part of the universe that we observe as it was long ago is also far away. a galaxy that is 2 500 000 (2.5 million) lightyears away looks as it did 2 500 000 years ago. it is much nearer so we observe it as it was much more recently. the light emitted 13 700 000 000 years ago from where that galaxy is now has "past us by", but the cmb from the much more distant universe is still observable because it has taken much longer to get here.

the earth did not exist 13 700 000 000 years ago. only the atoms of hydrogen here on earth existed. the helium on earth is made on earth as a result of the decay of certain unstable atomic nuclei in the crust and trapped there. everything else (carbon, nitrogen, oxygen, neon, silicon, iron, nickel, zinc, silver, tin, platinum, gold, mercury, lead, and many more) did not exist because they formed inside certain stars and supernovae. earth is only about 4 500 000 000 (4.5 billion) years old.

Answer 2

No one was around to verify that the big bang occured. The idea for the big bang was created as a minor explanation of the orgin of the universe. The computations for the big bang failed completely at 10 -43 sec after the event and was given new life through the process of renormalization. It is a good theory though.
The light you speak of would encompass an area twice the light years you envision due to the fact that the light would be a radius of the diameter of a sphere of light. To understand more check out "light cone" on the internet.
The truth of the matter with this and the other answers is that no one knows the origin of the universe, or the origin of the laws of physics. No one knows the vastness of space or the origin of the wave particle known as light. It is all still a mystery. Perhaps you will find the key.

Answer 3

I'm not sure exactly what you're getting at - but the Earth was definitely not here before the big bang. Many objects in space emanate light for long periods of time - it depends on how far an object is from Earth and how long ago it may have stopped emanating light if we can see it or not - also, don't be sorry for a serious question.

Answer 4

Hi. The big bang is a theory of how the universe may have come into being. The present estimates are over 13 billion years ago, so the Earth would not have existed then.

Answer 5

Do you mean...the microwave background? The microwave radiation that seems to be permeating the universe, that is believed to be from the big bang?

There's actually some doubt as to how much of that came from the big bang (if any).

And the reason ( i think ) that this light would be reaching earth even now is that space expanded faster than the speed of light when the big bang happened. But im not certain.

Answer 6

no it is not like that earth also came after the big bang only but if we see billions light years distance we can see what happen in big bang
it is because light year is nothing but the distance traveled by light in a year

Answer 7

You have some common misconceptions. The big bang model is NOTan explosion from a central point. it is an expansion of all of space. The Big Bang happened everywhere. There was no special point. Light shortly after the big bang is reaching us from every direction.

Answer 8

The problem with your question is that, "black holes" are an impossibility - really. Were you to determine the speed of a mass 0.716 miles outward from the center of our planet, that mass would be exceeding the speed of light in one second. Inside our sun the distance is 400 miles. According the the black hole advocates, black holes should have formed within our planet and our sun.

What you are speaking of is a theory - no matter how it is played out. When you consider the basis of our universe as found in two common equations, E = mc2, and m = E/c2, you find that the basis of it is physical time "c2". Whatever would not have as its composition physical time, it could not exist to us. If it is impossible for "black holes" to form, the concept of a "big bang" is a greater impossibility.

"The Problem and Repair of Relativity" and "Magetism and Gravity" http://360.yahoo.com/noddarc are short papers that speak to this.

Answer 9

THERE WAS NEVER ANY BIG BANG that isnt true the world is only about 2000 years old there is no such big thing as a big bang ppl cant evolve from particles and we cant evolve from monkeys that is physicaly impossible read the bible youll learn stuff on how the ppl were really created WE DIDNT EVOLVE FROM PRIMATES

Answer 10

big bang itself is very controversal theory, it is just most probable clue not a true thing.
