Is there vacuum at the Event Horizon of a Black Hole?

AI Thread Summary
The discussion centers on the presence of a vacuum at the event horizon of a black hole, where virtual particle pairs are formed, violating conservation of energy. Near the event horizon, one particle is drawn into the black hole while the other escapes, resulting in Hawking Radiation. The existence of a vacuum at this location allows for the creation of these particle-antiparticle pairs. The conversation also raises questions about the mean free path of particles near the event horizon. Overall, the nature of vacuum in this extreme environment is complex and warrants further exploration.

As all of us know that in a vacuum the particle antiparticle pairs or the virtual particles are created violating the law of conservation of energy.

So even near an Event Horizon of a Black Hole virtual particles are formed. One of the particles gets sucked into the black hole but the other remains emitting a radiation called Hawking Radiation.

So is there vacuum at the surface of the event horizon due to which particle antiparticle pairs are created?

Yes, but there are vacuums and there are vacuums. Ask what the mean free path might be near the horizon.
 

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...

Thread 'Can the signal WOW be explained by the maser effect?'

This hypothesis of scientists about the origin of the mysterious signal WOW seems plausible only on a superficial examination. In fact, such a strong coherent radiation requires a powerful initiating factor, and the hydrogen atoms in the cloud themselves must be in an overexcited state in order to respond instantly. If the density of the initiating radiation is insufficient, then the atoms of the cloud will not receive it at once, some will receive it earlier, and some later. But then there...
