Vacuum Response to Cosmic Stretching: Accel- Erated Universe and Prevention of Singularity
نویسنده
چکیده
Spacetime stretching is included in the general relativity alongside with the spacetime curvature. Response of the vacuum to cosmic stretching is considered as macroscopic quantum effect. This effect explains the accelerated expansion of the Universe without resorting to Plank scale. For negative stretching (collapse) the same effect can prevent formation of singularity. Stretching effect can be important for a variety of cosmic phenomena, including collisions of galaxies and local collapses.

Vacuum Response to Cosmic Stretching
The Einstein equation of the general relativity (1) postulates a balance between the spacetime curvature and the energy-momemtum. Initially, Einstein introduced the cosmological constant (CC) Λ into the equation to make the steady state cosmology. When the expansion of the Universe was discovered, Einstein dismissed CC as his greatest blunder. Recent observations of the type Ia supernovae [1,2]...

Gravitational waves are the last unconfirmed prediction of the general relativity. These waves are tiny fluctuations in world frame that dessipate energy throghout space. The gravitatinal waves spectra of fluctuations can be originated from the non-linear effects during different cosmic evolution periods, especially from initially non-linear and excited vacuum state in the very early universe. ...

We use an explicit Randall-Sundrum brane world effective potential as congruent with conditions needed to form a minimum entropy starting point for an early universe vacuum state. We are investigating if the Jeans instability criteria mandating low entropy, low temperature initial pre inflation state configuration can be reconciled with thermal conditions of temperatures at or above ten to the ...

Here, an accelerated phantom model for the late universe is explored, which is free from future singularity. It is interesting to see that this model exhibits strong curvature for all time in future, unlike models with 'sudden future singularity' showing high curvature near singularity time only. So, quantum gravity effects be dominant as time increses in late universe too. More importantly, it...
