Their journey and findings would be lost to the rest of the entire universe for all time.
Keeping in mind that nothing can escape the gravitational pull beyond the event horizon, the in-falling person would not be able to send any information about their findings back out beyond this horizon. Now, if a person found an isolated supermassive black hole suitable for scientific study and decided to venture in, everything observed or measured of the black hole interior would be confined within the black hole’s event horizon. To enter one safely, you would need to find a supermassive black hole that is completely isolated and not feeding on surrounding material, gas and or even stars. They are most certainly not hospitable and would make traveling into the black hole extremely dangerous. These disks are called accretion disks and are very hot and turbulent. Most black holes that we observe in the universe are surrounded by very hot disks of material, mostly comprising gas and dust or other objects like stars and planets that got too close to the horizon and fell into the black hole.

In other words, if the person is falling feet first, as they approach the event horizon of a stellar mass black hole, the gravitational pull on their feet will be exponentially larger compared to the black hole’s tug on their head.
COULD A HUMAN SURVIVE GOING INTO A BLACK HOLE FREE
This implies, due to the closeness of the black hole’s center, that the black hole’s pull on a person will differ by a factor of 1,000 billion times between head and toe, depending on which is leading the free fall. Thus, someone falling into a stellar-size black hole will get much, much closer to the black hole’s center before passing the event horizon, as opposed to falling into a supermassive black hole. The supermassive black hole at the center of our Milky Way galaxy, by contrast, has a mass of roughly 4 million solar masses, and it has an event horizon with a radius of 7.3 million miles or 17 solar radii. For a black hole with a mass of our Sun (one solar mass), the event horizon will have a radius of just under 2 miles.
The radial size of the event horizon depends on the mass of the respective black hole and is key for a person to survive falling into one. Even light, the fastest-moving thing in our universe, cannot escape – hence the term “black hole.” Leo and Shanshan, CC BY-NDĪt the event horizon, the black hole’s gravity is so powerful that no amount of mechanical force can overcome or counteract it.
The distance from a black hole’s center of mass to where gravity’s pull is too strong to overcome is called the event horizon.
