## What would happen if someone went inside a black hole?

The gravitational attraction of a black hole is so strong that not even light can escape it. Spaghettification: A black hole would stretch an astronaut’s body into a thin ribbon, since the gravity pulling on their feet is so much stronger than on their head. …

### What happens to an object that falls within the event horizon of a black hole?

When an item gets near an event horizon, a witness would see the item’s image redden and dim as gravity distorted light coming from that item. Within the event horizon, one would find the black hole’s singularity, where previous research suggests all of the object’s mass has collapsed to an infinitely dense extent.

What would it look like to watch someone fall into a black hole?

Falling into a black hole might not be good for your health, but at least the view would be fine. Light from stars directly behind the hole is swallowed by the horizon, while light from other stars is merely bent by the black hole’s gravity, forming a warped image around the hole.

What does the event horizon of a black hole look like?

The event horizon is in the middle of the image; we can see the shadow (it looks like the top half of a circle, somewhat darker than its surroundings). The rotating accretion disk can be seen surrounding the shadow.

## What happens inside the event horizon?

event horizon, boundary marking the limits of a black hole. At the event horizon, the escape velocity is equal to the speed of light. Thus, nothing that enters a black hole can get out or can be observed from outside the event horizon. Likewise, any radiation generated inside the horizon can never escape beyond it.

### What’s inside a wormhole?

Wormholes contain two mouths, with a throat connecting the two. Certain solutions of general relativity allow for the existence of wormholes where the mouth of each is a black hole. However, a naturally occurring black hole, formed by the collapse of a dying star, does not by itself create a wormhole.

Are wormholes real?

A wormhole can be visualized as a tunnel with two ends at separate points in spacetime (i.e., different locations, different points in time, or both). Wormholes are consistent with the general theory of relativity, but whether wormholes actually exist remains to be seen.

What happens outside a black hole?

We understand what happens outside the black hole as you approach its event horizon, that infamous point of no return. The event horizon is where the escape speed exceeds the speed of light: you’d have to be going faster than light (which is impossible for any bit of matter) to escape the black hole’s gravity.

## What is the event horizon of a rotating black hole?

A rotating black hole’s event horizon separates into an outer horizon and an inner horizon. The outer event horizon of such an object acts like a point of no return, just like the event horizon of a nonrotating black hole. The inner event horizon of a rotating black hole, also known as the Cauchy horizon, is stranger.

### What happens to photons when they fall into a black hole?

But in practice you would disappear: the photons lose energy as it becomes harder for them to climb out of the black hole’s gravitational well nearer the event horizon, and their wavelength would increase until it grew past the observer’s detection capabilities — making the image invisible.

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.
