Astrophysics professor teaches how to jump into a black hole so it's 'safe' and possible events

Our knowledge of black holes has improved greatly in recent times, with landmark works such as the image of the supermassive black hole Messier 87 and the recent discovery of a supermassive black hole. 3 times the sun right in our galaxy. What if we decide to take the next step: visit, even go into a black hole?

First, in order to survive long enough to explore a black hole, you have to find a very large one, says Janna Levin, a professor of astronomy at Columbia University's Barnard School. Black holes form when matter is compacted into a very small space, like when a star is so large that gravity is so strong that the star compresses its own mass, creating a point in space where the force of gravity is strong. infinite gravity - a Singularity. The surrounding area attracts everything that happens to pass by also known as the event horizon.

Our knowledge of black holes has improved greatly in recent times, with landmark works such as the image of the supermassive black hole Messier 87 and the recent discovery of a supermassive black hole. 3 times the sun right in our galaxy.

As matter becomes more and more sucked into the singularity at the center of the black hole, the event horizon widens. If you accidentally jumped into a small black hole, say 100 miles across - you'd be very close to the point of infinite gravity. The change in gravity before even passing the event horizon is so great that you will be slowly stretched into fear, a terrifying process known as spaghettification.

Instead, you should aim for a giant black hole, like the black hole of the galaxy M87, 3 million times the diameter of Earth. When you cross the event horizon you are 12 billion miles away from the singularity. You will simply pass, a long time. You could go a whole year before being completely destroyed by the center of the black hole.

In addition, you should avoid black holes with accretion disks. About 1% of supermassive black holes form very rapidly rotating disks of matter, which can have temperatures up to millions of degrees and produce the largest measurable magnetic fields. Magnetic fields of this magnitude are often capable of shutting down your nervous system and pulling the molecules in your body apart into many microscopic fibers until you disintegrate.

If so, how do scientists study black holes?

The image above is the product of the Event Horizon telescope, the result of a collaboration between more than 200 researchers around the globe. They used a technique called baseline interferometry, in which eight radio observatories around the world synchronize and create a radio telescope the size of Earth, powerful enough to make observations with high precision. 4,000 times higher resolution than the Hubble Telescope.

The team also recently published new images showing the speed at which the black hole M87 swallows up surrounding objects and shows a cobweb-like magnetic field structure, rotating around the black hole and creating giant waves of matter .

If you still want to explore, you can probe the 'ergosphere' region of the black hole. This is the region beyond the event horizon where space revolves with the black hole. It is hypothesized that there could be entire solar systems within this region. If you're stuck here, you still have a way out: By hurling a small meteor into a black hole, you can take advantage of this torque to 'shoot' yourself to safety.

If you're determined to jump straight into the center of a black hole, you won't regret it. When you get close to the black hole, you will see that the light of the entire universe seems to be distorted by the black hole's enormous gravity. It's like walking through a mirror house. The light from the stars will drift across the sky, you can see an object leaving many afterimages because the black hole bends the light reflected from the object. But the fireworks didn't stop here. The inside of a black hole is not black at all. It was a one-way door to a dimension that contained epochs of light locked within it. You will see the entire history of a black hole from its formation in a moment.

Time will also slow down due to the infinite gravity of the black hole. Looking in from the outside, your motion is so slow that it's like you're frozen at the event horizon, even though you've already reached the center of the black hole. From your perspective, the universe seems to be accelerating. If you look back as you drift into the center of the black hole, you can see it as if you were watching a movie about the entire universe, right before you died.

There is still a possibility that there is a way out, but this is entirely within the realm of theoretical physics. A black hole can also be a wormhole, taking you to another part of the universe - in a state where the body has decayed into many elementary particles. All you can expect is the possibility that quantum data about you is preserved as it passes through the black hole, and the existence of a kind of 'soul' patient enough to spend infinite time reassembled. The biological machine used to be you.
