Questions about Time

[AbstractDreamer]

Ok so the sum is the same, but the larger the region, the more likely a large fluctuation will appear somewhere?

 

Are energy fluctations either positive or negative, or are they multi dimensional?

 

Do positive fluctuations ever "materialise" into something permanent or non-virtual?

 

What happens in the negative locations? Anti-energy?

[Mordred]

The larger the region the more fluctuations will happen. Fluctuations always occur in matter/antimatter pairs.

 

Now there are circumstances where virtual particles can become real. In all cases its by a dynamic that seperates the pair from annihilating each other.

 

1) quantum tunneling ie Hawking radiation

2) rapid expansion causing seperation (inflation, an older model is Parker radiation) today often referred to as the inflaton in Guths false vacuum inflation and later inflation models such as chaotic eternal inflation.

3) Cosmological horizons (Unruh radiation)

which also involves tunneling.

 

They all involve tunnelling but the reasons behind the tunnelling can have different causes.

 

Think of a waveform with two sinusoidal humps. The second hump lower than the first. Tunneling is when the particle jumps from the higher (false vacuum hump to the lower true vacuum hump) it always higher energy to lower energy never the opposite. The potential difference between the two humps is the barrier.

 

So if you have a higher vacuum region tunnelling can occur to a lower vacuum region. If the virtual particles have enough energy to cross the barrier.

 

On Hawking radiation this is slightly different same for Unruh radiation. treat both as the same. Hawking radiation occurs outside the EH. One particle crosses the EH lost forever while the opposite escapes via tunnelling.

Sigh lol. How did I not guess 1 question = 5 more questions.

 

No more questions for now, I need to study QM basics.

 

Thanks for all your patience.

Questionology the study of asking questions.

Questography the measurement of asking questions.

quantum fluctuations are in essence a result of field fluctuations in QFT treatment. A field can have a measured zero energy but that is the average energy of the field. Localized regions of a field will still have fluctuations even when the average field energy is zero.

 

The Heisenburg uncertainty principle is intrinsic to field's as well. Its more often called vacuum state but it amounts to the same

Heisenberg.

If the time is orthogonal to the other three spacetime dimentions, we may have been able to travel independently along spatial dimension and time. As that is quite not possible. We can't make change in postion without advancing through time and also can't completly travel in time as there is no absolute rest possible. I think!

Our four-velocity has a magnitude of c. As you travel though space at some speed, your passage through time slows. They are not independent of each other.

Apparently information can change position without advancement in time. IF you prescribe to action-at-a-distance interpretation of QM.

Not necessarily. Position can be defined as a distance and direction measured from a reference. In order to have a change of position then one or the other of these two things must change.

 

Time must elapse in order to have a change in distance of any particle (or point) from the reference. It is possible for this change in distance to cause no change in direction from the reference.

 

Let's break this down so that we are looking only at distance or direction independently. We know that no two points can change distance from one another at a rate that is faster than c. But how about direction? Is the change in direction limited by c? Nothing that I know of in physics would prevent the change in direction between any two points from occurring simultaneously synchronously.

 

There is math (that no one seems to understand because I am so limited in my ability to explain it) that shows that directions are all connected to one another through an equation (similar to the way distances are relative to one another using Pythagoras or pi.) Since these equations that relate directions to one another are invariant under relativistic transformations, then one might reasonably assume that direction isn't something that is hampered by the universal speed limit.
