The Big Bang?

Question

I just want to talk about the Big Bang -- nothing else. Why is it that even though there is a LAW against planets forming from gas, dust, and whatever -- Boyle’s law (Gas clouds dissipate outward ) -- people stil believe in the Big Bang? And another thing if the creation of the universe was random, chaotic, and unpredictable, modern scientific investigation could never have been developed.

PS -- I'm posting this in here since I know there r so many Atheists that r trying 2 find God... that was sarcasm 4 those of u who don't know.

All celestial objects have their own local gravitational fields, and it is commonly assumed that particles like gas, dust, and meteors that come within the sphere of gravitational influence of larger bodies will be pulled into those bodies. But this is not what is observed.

An example is found in the space program where the astronauts on the way to the moon dumped waste material outside their spacecraft. Where did it go to? It didn’t fall off into space or fall back onto the spacecraft. It followed the spacecraft all the way to the moon slowly orbiting the spacecraft as captive moons.

Planets can’t “sweep up” material objects moving in orbit similar to their own. An object outside a body’s sphere of influence cannot reach the edge of the sphere if it doesn’t reach a relative velocity that matches escape velocity at that distance from the body.

Answer 1

Boyle's law does not say that Gas clouds dissipate outwards. It says that given a volume of gas, pressure is inversely proportional to volume and their product is a constant.

Boyle's law also only applies to "ideal gases." That is, it is only relevant when gravitational attraction is minimal. In the case of planetary formation, the dust clouds were sufficiently large such that gravitational attraction became relevant, causing the clumping effect.

The creation of the universe was random, chaotic, and unpredictable only to a certain degree. It still followed a set of natural laws, and we can use those laws to understand the universe. It's true that if the Big Bang happened without a set of laws science wouldn't work, but fortunately we live in a universe determined by natural law.


EDIT:
It is also not surprising that something dumped off of a spaceship going to the moon would also go to the moon. The effect of gravitational acceleration on the things dumped out of the spaceship was minimal, so we would expect their velocity vectors to change only minimally. Therefore, we should expect them to follow the spaceship in the same direction they were going.

Also, the planets did not "absorb" outside things to form. Look up the nebular hypothesis to see what I mean. The clouds of nebular dust were sufficiently large to clump together through their own gravity.

Answer 2

You are trying to say that Boyle’s law says that planet formation by the gravitational accumulation of dust and other debris is impossible?

Ok, if the gasses all expand outward, then why does out atmosphere stay with us? Gravity is preventing it from escaping.

Given time, enough material will accumulate to start to build a gravitational field which will allow it capture more material. Eventually, the field will be strong enough to keep gases from escaping. If you have not noticed, the Earth is a bit bigger than the Moon. Earth's gravitational field is about 6 times stronger.

Try studying science a bit. I mean actually studying it. Go to some classes and sit and pay attention and learn. Don't just let someone tell you your science. I wonder if you can even name other gas laws without having to look them up online or if you can even describe Boyle's law without looking it up online. First of all, it is not "Gas clouds dissipate outward". It is "In a closed system, pressure and volume are inversley proportional with a fixed mass of gas at a fixed temperature."

Also your paragraph here is pretty confusing. What are you trying to say?
"Planets can’t “sweep up” material objects moving in orbit similar to their own. An object outside a body’s sphere of influence cannot reach the edge of the sphere if it doesn’t reach a relative velocity that matches escape velocity at that distance from the body."
Are you saying that Earth's gravity cannot capture another object? Do you realize that tons of material are captured by Earth's gravity every day?

Another observation for you. If you believe that Boyle's Law says that gas clouds dissipate and thus, cannot concentrate, then how do clouds form in the first place? I am talking about rain clouds. If the gasses tend to dissipate, then you would not expect them to concentrate enough to make a nice rain cloud. Yet, we still have rain clouds. I guess your personal version of Boyle's Law needs a little tweaking. The rest of us will stick with the scientific version.

Answer 3

With all due respect, Boyle's Law is a special case of the Ideal Gas Law, which talks about the relationship of a gas's pressure, volume and temperature under certain conditions. It does say that a cloud of gas under pressure will tend to disperse. If that was the end of the matter, there would be no atmosphere around the Earth. After all, the atmosphere is just a cloud of gas, right? You have to factor other things in, particularly gravity.

Answer 4

"Big Bang" is a coined phrase originally used in mockery of the theory. In many respects it is completely incorrect. The Big Bang was actually a sudden expansion of space from some point that we lack the instruments to detect, as it is shielded from us by the particle horizon in which matter was first allowed to form out of energy. Prior to that the universe was opaque, so there are only hypothesis to explain what existed before then.

Answer 5

Your understanding of physics is sadly flawed and it would take me several dozen pages to teach you what exactly you are wrong about. And BTW Boyle's Law states that "[f]or a fixed amount of gas kept at a fixed temperature, P and V are inversely proportional." Where in there is what you said? It has to do with gases under the effects of OUR atmosphere ONLY and does not apply to dust clouds in space.

Answer 6

“ For a fixed amount of gas kept at a fixed temperature, P and V are inversely proportional " That's Boyle's Law. So "WHO" fixed the temperature?If man was not around,and if the so called Big Bang just "happened" who? Maybe God was there in the beginning like the Word states...and we just fail the see it.

Answer 7

God created the BB when He said Let thre be light. It was a different lght than the one we know of. It acted on the particles of Dark Matter that was all that existed, pushing it out in all directions and acting on some of it to transform it into the matter we know.

You have undoubtedly seen a documentrat or simulation of a nuclear bomb explosion and how everthting got blown away. Well, it was rather like that, except infinitely more powerful because they can still measure the echose of it even today.

Answer 8

Vishal did a fine job with his answer. Dumping stuff out the door isn't pushing it away. So until you change speed, it is going to be right there. Didn't you ever watch Star Wars? That is why they dumped garbage right before accelerating.

Like I said before, you are implying that gas could not hold to the surface of a planet. It observationally does. So that pretty much tells you the rest is crap.

Answer 9

I'm still voting that we get to move questions to the appropriate sections if the posters are incapable of it themselves.

Science section, anyone?

Answer 10

Did the big bang go boom?
