How can something escape a black hole during an event horizon?
Since general relativity states that nothing can travel faster than the speed of light, nothing inside the event horizon can ever cross the boundary and escape beyond it, including light. Thus, nothing that enters a black hole can get out or can be observed from outside the event horizon.
What happens if an object crosses the event horizon of a black hole?
The event horizon of a black hole is the point of no return. Anything that passes this point will be swallowed by the black hole and forever vanish from our known universe. At the event horizon, the black hole’s gravity is so powerful that no amount of mechanical force can overcome or counteract it.
What stops within a black hole?
According to Einstein’s theory, time and space, in a way, trade places inside the hole. Inside the black hole, the flow of time itself draws falling objects into the center of the black hole. No force in the universe can stop this fall, any more than we can stop the flow of time.
What keeps a black hole from collapsing?
Left alone, black holes lose mass due to ‘Hawking radiation’, so that their event horizons are slowly shrinking. But, the interior of the black hole, or its ‘singularity’ (the point at which all the black hole’s matter is concentrated) has already reached the limit of its density and cannot ‘collapse’ any further.
Can neutrinos escape a black hole?
No, neutrinos are not above participating in gravity and can not escape or pass through black holes. Neutrinos were once believed to have zero mass.
What can destroy a black hole?
Only way to destroy a black hole is to explode it so that it’s no longer a black hole. Black hole’s singularity is a point space.
Where is the event horizon of a black hole?
It is widely accepted that inside the Accretion Disc of a black hole there is the Event Horizon; called the ‘Event Horizon’ because events are thought to cease here because we assume here is where time stops.
Can matter fall to the centre of a black hole?
According to theorists, if time no longer exists inside the Event Horizon, then matter cannot fall to the centre of a black hole. Can matter even exist if there is only a single point dimension?
Is there a singularity at the centre of a black hole?
Surely, if there is no time, then matter cannot travel to the presumed singularity at the centre of the black hole. If this is the case, then there can be no singularities at the centre of black holes. To follow the logic, matter at the Event Horizon must be close to infinitely compressed in an incredibly thin shell that forms the Event Horizon.
Is time travel possible in a black hole?
The inner event horizon of a rotating black hole, also known as the Cauchy horizon, is stranger. Past that threshold, cause no longer necessarily precedes effect, the past no longer necessarily determines the future, and time travel may be possible.
