What is the force that causes apparent acceleration of universe as it expands ?

Question

If the Big Bang was like an explosion, we would not expect bits and pieces to accelerate the further they are from the source of the bang, yet astronomers say that objects are accelerating, the more so as they are at the outer limits. Is it simply like an implosion effect, like matter moving from a partial vacuum into an absolute vacuum, i.e. from an area of some matte to an area of no matter?

Answer 1

It has no specific name, but is called Dark Energy!

It is supposed to amount to about then 2/3 of all the energy in the universe. It is a force that counteracts gravity (the opposite of gravity). We know very very little about anything to answer a question such as this. Many things known will have different answers then they do now in few and many years to come.

Answer 2

Before it was discovered that the rate of universal expansion is increasing, most cosmologists believed that the universe was expanding due to a phenomenon known as 'inflation.' (...http://www.edge.org/documents/day/day_guth.html...) The inflationary theory basically states that just after the Big Bang event, the universe underwent a very brief rate of expansion that exceeded the speed of light. That's allowed under relativity because it's space expanding faster than 'c.' Anyway, that's what was believed to have given the universe its initial expansion.

Now all that's been knocked into a cocked hat because it's been found that the rate of expansion is increasing. No one...repeat, no one...knows why. Some unknown force is apparently counteracting the effects of universal gravitation that *should* be slowing down the expansion. This unknown force is called 'quintessence' (..fifth force..) or just simply 'dark energy.' Some who've responded to your question call this a cop out, but nobody's copping out when they truthfully admit that they don't know what exactly is going on with regard to cosmic expansion.

FYI --
The increased rate of expansion is 1.3 minus 15 km/sec/sec per mega-parsec.

Answer 3

Currently, there is no answer. I've heard it suggested that it is an effect of being in a "closed" universe, but it is nothing more than a suggestion at this time.

The thing about the 'big bang', and what you call a 'partial vacuum' is inconsistent - because the universe *can't* (by definition) be affected by anything outside of it. In other words, such a 'force' should be felt everywhere - and should be measurable as being part of *this* universe - because it's affecting *this* universe.

Answer 4

keep in mind that area exists basically interior the Universe and there is not any which means to the term "exterior the Universe". What happens in enlargement is that the gap itself is increasing. in the beginning, the enlargement of the universe would not encompass galaxies moving by some static area, yet somewhat the "stretching" of the gap itself. the sunshine is moving by this increasing area and has to trip the preliminary distance plus despite distance is extra because of the universe's enlargement in the process the direction of the adventure. this is like working on a racetrack that's being stretched -- if the racetrack began off a hundred meters long yet have been given stretched to an fairly final length of four hundred meters as you have been working from start to end, then the completed distance you have run is extra advantageous than a hundred meters. subsequently, whilst we communicate of galaxies receding from us because of the enlargement, this is not any longer that the galaxies are moving, however the gap in between us and the galaxies is increasing.

Answer 5

Big G, thank you! I had always thought that I was the only one who considered this possibility, and therefore there must be some fatal flaw to it. I even submitted this idea to that "Ask a physicist" website and got the answer that it was currently believed that some kind of dark energy must be at work, and in response to my proposal (that the majority of matter in the universe is receeding from us at beyond the speed of light, yet is sub-light to distant objects, and that this matter was decelerating from the BB thus accelerating matter at the extreme edges of our part of the universe), she said that, since we can have no knowledge of objects receeding from us at greater than c, we cannot test such a hypothesis.

I didn't reply back, but I thought, hmmm, difficulty of testing a hypothesis has nothing to do with it's likehood of correctness; besides, if this hypothesis were true, we actually would be seeing it's effect on rapidly-receeding distant objects even if the cause would be hidden from us due to it's superluminal speed.

Hell, idunno...........

Answer 6

Distant objects are accelerating away from the big bang - there is no answer yet.

I had this discussion with some y11 students years ago - the best hypothesis I heard from one of them was that all objects seem to be pulled and accelerate by the force of gravity. The student theorised that there must be some enormous mass beyond our detection that circles the universe that is pulling the distant objects.

Its as good a theory as any i've heard.

Answer 7

The thing is that Big Bang is a "mutually-responsive" force. Therefore, the Big Bang that exploded in another universe on different time line, weather parrelel or not is still achoing in this time line. This is the way of the Universe to keep on pulsating. It the ever living being.
As for the backwards Big Bang....if we for the moment imagine that we are in the Black Hole, then contraction and implosion doesn't seem too weird. From this point of view our world is actually going back rather then progressing forward.

Answer 8

The current view of the universe is wrong. It is actually imploding converting the weak gravitational force into the strong electromagnetic force.
Yes we are speeding up because when the core implodes from gravity it causes Piezoelectricity causing the force of gravity to change and increase to tens of millions of pounds of electromagnetic force per cubic centimeter.
The universe is electric and can be easier compared to plasma physics than todays current big bang myth.
If you read up on Piezoelectricity and converse piezoelectricity, you will see that the universe behaves this way and that the core of the galaxy and the universe beat like a heart and transfer all its energy to it's surrounding bodies by resonance.
The universe will always speed up because the electromagnetic force is tens of milions of times greater than the gravitational force and each time the core beats the force will increase...and this goes on to infinity.
Dark energy and the Big bang is a big myth that is beeing fed to the public to keep people from discovering that you can get free energy by converting gravity into electricity because of Piezoelectricity. Here is an example, If you put a 500 pound granite rock on a capacitor it will convert the force of gravity into electricity because granite contains Quartz (which is piezoelectric) and 500 pounds of gravitational force on this stone will produce 12,500 volts per cubic centimeter.
Force = mass x accelleration
You can power a small city from a granite stone because of gravity..and there are no moving parts. All you need is to put a heavy granite stone on a big capacitor and have a spark gap and you will get free energy forever from the sun even when the device is in the dark.
The textbooks will never tell the public the truth because the elite of the world dont want people to have free energy. We have known this for the last 2000 years and if you look hard enough you can see that the bible already tells us how to build this energy device. It's called the Ark of the covenant and you have to put Jacobs stone on it ( a 450 pound stone of granite)
The accelleration of gravity here on earth is 9.8 so the force of gravity of that granite stone is 9.8 x 500 almost 5000 pounds of force with gravity alone... but when the capacitor fires, the force increases to tens of millions of pounds...
You start out with 5000 pounds of force and end up with tens of millions of pounds of force in a split second.... you figure it out. It's so obvious how the universe works.

Answer 9

No one actually knows - but current thinking is that it's dark energy that is causing the universe to expand.

Answer 10

They are calling it dark energy. But I think that is a cop out. The fact is, they don't have any idea what it is so they just call it dark energy. Energy because it causes expansion and dark because it is mysterious and unknown.
