Summary
Loop quantum cosmology impacts rotating black hole evolution by slightly delaying evaporation with higher rotation. This model predicts greater black hole formation than standard cosmology.
Area of Science:
- Cosmology
- Astrophysics
- Quantum Gravity
Background:
- Rotating black holes (RBHs) are key objects in astrophysics.
- Understanding their evolution is crucial for testing cosmological models.
- Loop quantum cosmology (LQC) offers a framework for quantum gravity effects.
Purpose of the Study:
- To investigate the evolution of rotating black holes within LQC.
- To analyze the influence of rotation and accretion on RBH lifetimes.
- To compare black hole formation in LQC versus standard cosmological models.
Main Methods:
- Theoretical modeling of RBH evolution under LQC.
- Analysis of parameters including angular momentum and accretion efficiency.
- Astrophysical constraint analysis.
Main Results:
- Accretion of dark energy has a minor effect on RBH evolution.
- A higher rotation parameter slightly delays RBH evaporation times.
- LQC suggests a greater tendency for black hole formation compared to standard cosmology.
Conclusions:
- The rotation parameter influences RBH lifetime, with higher values delaying evaporation.
- LQC provides a potentially more favorable environment for black hole formation.
- This study offers insights into quantum gravity effects on black hole dynamics.

Although black holes were theoretically postulated in the 1920s, they remained outside the domain of observational astronomy until the 1970s.
Their closest cousins are neutron stars, which are composed almost entirely of neutrons packed against each other, making them extremely dense. A neutron star has the same mass as the Sun but its diameter is only a few kilometers. Therefore, the escape velocity from their surface is close to the speed of light.

No object with a finite mass can travel faster than the speed of light in a vacuum. This fact has an interesting consequence in the domain of extremely high gravitational fields.
The minimum speed required to launch a projectile from the surface of an object to which it is gravitationally bound so that it eventually escapes the object’s gravitational field is called the escape velocity. The escape velocity is independent of the mass of the object. Merging the idea of escape...

Angular variables are introduced in rotational dynamics. Comparing the definitions of angular variables with the definitions of linear kinematic variables, it is seen that there is a mapping of the linear variables to the rotational ones. Linear displacement, velocity, and acceleration have their equivalents in rotational motion, which are angular displacement, angular velocity, and angular acceleration. Similar to the rotational variables, a mapping exists from Newton's second law of motion...

In 1905, Albert Einstein published his special theory of relativity. According to this theory, no matter in the universe can attain a speed greater than the speed of light in a vacuum, which thus serves as the speed limit of the universe.
This has been verified in many experiments. However, space and time are no longer absolute. Two observers moving relative to one another do not agree on the length of objects or the passage of time. The mechanics of objects based on Newton's laws of...

01:09Conservation of Angular Momentum
10.2K
A system's total angular momentum remains constant if the net external torque acting on the system is zero. Considering a system that consists of n tiny particles, the angular momentum of any tiny particle may change, but the system's total angular momentum would remain constant. The principle of conservation of angular momentum only considers the net external torque acting on the system. While there are internal forces exerted by different particles within the system that also produce...

01:18Conservation of Angular Momentum: Application
10.9K
A system's total angular momentum remains constant if the net external torque acting on the system is zero. Examples of such systems include a freely spinning bicycle tire that slows over time due to torque arising from friction, or the slowing of Earth's rotation over millions of years due to frictional forces exerted on tidal deformations. However in the absence of a net external torque, the angular momentum remains conserved. The conservation of angular momentum principle requires a...
