See Objects Fall into Schwarzschild Black Hole?

In summary, it is not possible for an external observer to see an object falling into a Schwarzshild black hole. This is due to the fact that all Schwarzshild black holes have an Event Horizon, which would cause an endless redshift for the observer. However, if an observer were to fall into the black hole alongside the object, they would experience the same effects, but would not be able to share their experience with anyone else.

Is it possible to see an object falling into Schwarzshild black hole? I know that it's
imposibble in finite time for stationary observer (the observer who see the metric
stationary) but it maybe is possible for observer who is not stationary (has this
observer to fall into black hole?).

It isn't possible for an external observer to "see" any object cross an Event Horizon, and all Schwarzschild BHs have 'em! You'd see an endless redshift, of no comfort to the infalling bugger, who would notice nothing special as he passed from this into... that. (assuming an ideal "astronaut" who can survive the forces at play)

EDIT: Well, if you could fall into the BH, past the EH WITH the "Astronaut" then yes, you would share their experience. The problem of course is that you'd share their fate, and be unable to relate the tale! :wink:
 

FAQ: See Objects Fall into Schwarzschild Black Hole?

What is a Schwarzschild Black Hole?

A Schwarzschild Black Hole is a type of black hole that is characterized by its event horizon, the boundary at which the escape velocity exceeds the speed of light. It is named after German physicist Karl Schwarzschild who first described it in 1916.

How does a Schwarzschild Black Hole form?

A Schwarzschild Black Hole is formed when a massive star dies and collapses under its own gravity. As the star's core shrinks, its gravity increases, eventually becoming so strong that it creates a singularity, a point of infinite density and zero volume, at the center of the black hole.

What happens to objects that fall into a Schwarzschild Black Hole?

Once an object crosses the event horizon of a Schwarzschild Black Hole, it is unable to escape and is pulled towards the singularity at the center. As it gets closer to the singularity, the gravitational pull becomes stronger, causing the object to stretch and eventually be torn apart in a process known as "spaghettification."

Can anything escape from a Schwarzschild Black Hole?

According to classical physics, nothing can escape from a Schwarzschild Black Hole once it crosses the event horizon. However, some theories suggest that information may be able to escape through Hawking radiation, a type of radiation emitted by black holes due to quantum effects. This is still a topic of ongoing research and debate among scientists.

Are there any real-life examples of Schwarzschild Black Holes?

While we have not directly observed a Schwarzschild Black Hole, there is strong evidence for their existence in the form of observations of their effects on surrounding matter. The supermassive black hole at the center of our Milky Way galaxy, known as Sagittarius A*, is believed to be a Schwarzschild Black Hole with a mass of about 4 million times that of our sun.
