What is the exact calculation of Particle horizon in Lemaître model? Does it exist? Is it finite or infinite?
Can anyone calculate that integral?
Thanks

The Particle Horizon in the Lemaître model is a theoretical concept in cosmology that represents the maximum distance from which light could have reached us since the beginning of the universe. In other words, it is the boundary of the observable universe.
The Particle Horizon is calculated by using the comoving coordinates, which take into account the expansion of the universe. It is determined by integrating the speed of light over the age of the universe.
The Particle Horizon tells us about the size and age of the observable universe. It also provides insights into the expansion rate of the universe and the distribution of matter and energy within it.
The Particle Horizon is significant because it helps us understand the limits of our observable universe and the effects of the expansion of the universe on the propagation of light. It also plays a crucial role in studying the formation and evolution of large-scale structures in the universe.
The Particle Horizon is a theoretical boundary that represents the maximum distance from which light could have reached us since the beginning of the universe. On the other hand, the Hubble Sphere is the distance at which objects are receding from us at the speed of light due to the expansion of the universe. The Particle Horizon takes into account the age of the universe, while the Hubble Sphere does not.
