    0We are not discussing Black Holes.
    It goes somthing like this.
    Compress air in a bike pump the air will heat up, for you have done work compressing it, cool the bike pump and the air inside the pump and release the pressure on the plunger. The plunger won't return to the starting point till the expanding air is reheated.

    Now I understand the same principle applies to compressed liquids/ solids.
    Original state => Compressed => cooled then decompressed => must be warmed => Original state.
    There must be a warming phase to replace the heat lost during cooling to returm the material to it's original state.

    To it's original state. So, the Earth is like a basketball that inflates and deflates all the time. Now if true, according MD, galaxies should do the same thing.

    Will the universe as well?

    By this logic, cans of spray on deodorant should not work.

    You sound like you are getting a little wound-up and agitated.

    Look the material that formed the Earth once was in the form of a nebula. It has gone through a series of processes true. For a while there was compression, but now it has decompressed (not fully), but the expansion has slowed but is still measurable at 0.25 mm/year.

    The basket ball analogy would only be similar if the ball was placed in a hyperbaric chamber and deflated by raising the air pressure on the outside of the ball, and inflated by releasing that pressure.

    That is true for when they were in very cold conditions the rate of evaporation in the can could be slowed to the point the spray can won't work.
    They certainly work better if pre-heated.

    Trippy I feel as if you are deliberately trying to make fun of me and not seriously considering the science behind my hypothesis.

    So you do agree!

    The Earth is a basketball, inflated and deflated by the laws of physics.


    Why would you say I'm agitated when you agree?

    I would agree, according "by the laws of Physics"
    Why I thought you might be getting too excited was that you were widening the scope too much:

    Yes, because the viscosity of the paint varies according to temperature, so you don't get a smooth finish below some critical temperature, because the droplets don't spread properly.

    Also, the propellant is generally a gas under pressure. Gasses have boiling points. The effectivness of the propellant is dependant on the physical state of the propellant in the can.

    However, a compressed gas at room temperature will always expand.

    There's an equation you should familiarize yourself with:
    PV=nRT
    It means that if we have a constant mass of gas at a constant temperature, then increasing the pressure decreases the volume, and decreasing the pressure increases the volume.

    We can't inflate a balloon, cool it to room temperature, remove the balloon, and be left with a collection of compressed air.

    Maybe you should stop and consider why, if I am indeed doing that, I might be doing that.

    Well only you really know what drives you. But when in your reply you say something like this
    I really wonder!
    You obviously don't like what I am saying and how the evidence has been supporting my argument, I think you then try and introduce some really odd "red herring" stuff to throw the conversation along a weird path.
    Personally I don't mind discussing any particular science especially if it serves as an example of the type situation relevant to the topic we are discussing.

    I have wanted you guys to open up a bit as to your understanding of the whole theory. Right from the planet building, moon formation/capture, and provision of water on the Earth. Right up to the current day.
    Have you really thought it through? Or do you just feel the EE Theory is pseudoscience so let's kick ass.

    It's not a red-herring. It's an accurate restatement of what you were proposing here:
    And if you can't see it - consider a frictionless bike pump.
    What's the difference between having a wall that presents no resitance, and having no wall?

    Is none.

    What's more, if you understood what I actually said instead of this knee jerk "Stop picking on me" sobbing, you would realize the answer is right in front of you.

    In both cases what would actually happen is that as soon as the confining pressure is released the gas, whether it be in the balloon, or the bike pump, the gas would expand and cool.

    I can even tell you why this happens.
    Pressure is measured in terms of unit force per unit area.
    When I apply a force to a body of gas, whether it be compressing it in a bike pump, or inflating a balloon, I am applying a force that opposes the force applied by the pressure, and the volume will be reduced until the force applied by the pressure is equal to the constraining force (either your hand, or the elastic force provided by the balloon).

    If you cool the compressed volume back to its original temperature, then the same force is still going to be there.

    The only way to get around this is to cool it to well below its original temperature, and is probably going to involve a phase change, which has the result of reducing N. The point being, that the only way that your scenario has any validity is if you can cool it sufficiently to reduce P, because as long as a pressure differential exists, newtons laws of motion predict that expansion must occur. But if you do that, then all you have is a cold gas with its pressure in equilibrium with its surroundings. But, you can achieve the same result by simply cooling the gas at a constant pressure.

    @Trippy - would you be willing to relate that sort of science back to the compression decompression of the Earth then and I'll see if I can follow your objection?
    For I have been trying to locate an example of where rebound expansion is held back by lack of energy in the system.

    Like does a compressed coiled spring cooled to very low temperatures rebound slower than a hot spring?

    Still searching but found this one instead. The mantle melts on decompression. That's worth remembering, so it is not just temperature needed to make it fluid but a reduction in pressure will do the same thing.

    Wait.

    MD is talking about galaxies and black holes. You are on about the Earth and bike pumps.

    I'm confused.

    I'm talking about the natural progression of mass. Mass gets less dense over time. Mass evolves to space.

    You want proof? Here it is, the process of mass getting less dense over time, evolving to space. ALL the mass surrounding the core of this spiral galaxy came from the core, which we refer to as the black hole. In reality, this ENTIRE pic is of a black hole getting less dense. The black hole (spiral galaxy) once had a much smaller volume, but has since evolved to space and got less dense by means of expanding its volume!

    MD let me explain something to you. Proof is where you have some evidence to support your claim. Proof is NOT just stating your claim over and over, that is simply annoying, not proof.

    You can clearly see in the pic that the mass is moving away from the core and the entire object is getting less dense, no?

    And all the while each particle of the pic is also evolving to space. In order for the "universe" to expand all the objects that make up the "universe" must expand along with it. It happens at every level. Mass evolves to space!

    Are you 12 and just try to make an interpretation of some picture you saw?

    Are you so blind that you can't see it? What I say is in accordance with the second law of thermodynamics. What you say is rubbish!

    You say you can create a log from space. I say BS, that you can turn a log into space, but you can't turn space into a log! The natural progression of a log is for it to become less dense, by means of rotting away or by burning. You seem to imply the opposite, that the log was somehow magically created by a special blend of matter getting more dense. BS! Mass gets less dense over time! Mass evolves to space!

    You are a dipshit who found out that a quarter has two sides and thinks it's a miracle.

    And tries to explain it in anyway he can.
