In short, a person near a black hole will age slower compared to someone far away from the black hole. This is because the passing of time is slowed down due to the extremely strong gravitational field near the black hole and thus, any physical aging processes will also happen slower.
Stretching time
A clock near a black hole will tick very slowly compared to one on Earth. One year near a black hole could mean 80 years on Earth, as you may have seen illustrated in the movie Interstellar. In this way, black holes can be used to travel to the future.
Theorists say it's technically possible, but it would be a weird place to live. Supermassive black holes have a reputation for consuming everything in their path, from gas clouds to entire solar systems.
on edge of Black Hole. Space and time are intertwined, called space-time, and gravity has the ability to stretch space-time. Objects with a large mass will be able to stretch space-time to the point where our perception of it changes, known as time dilation.
Over time they shrink down to nothing and simply pop away in a flash of energy. It's not exactly fast. A good size black hole — say, a few times more massive than the sun — will take about 10^100 years to eventually evaporate through this process, known as Hawking Radiation.
Inside what's known as the black hole's event horizon, not even light itself can escape from a black hole. But that doesn't mean that black holes will live forever; on the contrary, they slowly decay away due to a phenomenon known as Hawking radiation.
New black hole simulations that incorporate quantum gravity indicate that when a black hole dies, it produces a gravitational shock wave that radiates information, a finding that could solve the information paradox. Perhaps the most enigmatic objects in the Universe, black holes embody many unsolved paradoxes.
To a distant observer, clocks near a black hole would appear to tick more slowly than those farther away from the black hole. Due to this effect, known as gravitational time dilation, an object falling into a black hole appears to slow as it approaches the event horizon, taking an infinite time to reach it.
Near a black hole, the slowing of time is extreme. From the viewpoint of an observer outside the black hole, time stops. For example, an object falling into the hole would appear frozen in time at the edge of the hole.
If there were a safe way to approach a black hole and see how it worked, it might look something like this. A new visual depiction of a black hole's impressive gravity by NASA reveals its warping of space and time.
Black holes are dark, dense regions in space where the pull of gravity is so strong that nothing can escape. Not even light can get out of these regions. That is why we cannot see black holes—they are invisible to our eyes. Because nothing can get out of black holes, physicists struggle understanding these objects.
There's nothing on the other side.
While researchers have never found a wormhole in our universe, scientists often see wormholes described in the solutions to important physics equations. Most prominently, the solutions to the equations behind Einstein's theory of space-time and general relativity include wormholes.
Bottom line: simply falling into a black hole won't give you a view of the entire future of the universe. Black holes can exist without being part of the final big crunch, and matter can fall into black holes.
Scientists using NASA's Chandra X-ray space telescope have discovered the remnants of a supernova 26,000 light years away that may contain a black hole that is only 1,000 years old, making it the youngest in the Milky Way galaxy.
Oldest black hole ever
What's astonishing is this is the oldest black hole that has ever been discovered in the universe, at the center of a galaxy just 570 million years after the universe began.
Solitary black holes can generally only be detected by measuring their gravitational distortion of the light from more distant objects. Gaia BH1 was discovered on 13 June 2022 by Tineke Roegiers. Gaia BH1 is 1,560 light-years away from Earth in the direction of the constellation Ophiuchus.
In astrophysics, spaghettification is the tidal effect caused by strong gravitational fields. When falling towards a black hole, for example, an object is stretched in the direction of the black hole (and compressed perpendicular to it as it falls).
A black hole is an extremely massive concentration of matter, created when the largest stars collapse at the end of their lives. Astronomers theorize that a point with infinite density—called a singularity—lies at the center of black holes.
The term dark matter was coined in 1933 by Fritz Zwicky of the California Institute of Technology to describe the unseen matter that must dominate one feature of the universe—the Coma Galaxy Cluster.
It is possible for two black holes to collide. Once they come so close that they cannot escape each other's gravity, they will merge to become one bigger black hole. Such an event would be extremely violent.
At the center of a black hole is what physicists call the "singularity," or a point where extremely large amounts of matter are crushed into an infinitely small amount of space.
Stellar black holes are very cold: they have a temperature of nearly absolute zero – which is zero Kelvin, or −273.15 degrees Celsius. Supermassive black holes are even colder. But a black hole's event horizon is incredibly hot. The gas being pulled rapidly into a black hole can reach millions of degrees.
Black holes are absolutely silent, as they are creatures of pure gravity. But while black holes produce no sound of their own, they can generate sound waves in their environment.
One Star's End is a Black Hole's Beginning
Most black holes form from the remnants of a large star that dies in a supernova explosion. (Smaller stars become dense neutron stars, which are not massive enough to trap light.)
