What is the black hole in simple terms?
A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying. Because no light can get out, people can’t see black holes.
What does a black hole do to spacetime?
Because the black hole is so massive and spinning so fast, it warps spacetime around it. The more massive the object, the more spacetime bends. If the massive object is also spinning, it causes spacetime to not only bend but to twist as well. Scientists call this effect “frame dragging.”
What exactly is a black hole in space?
A black hole is an area of such immense gravity that nothing—not even light—can escape from it. Black holes form at the end of some stars’ lives. The gravity on the inside of the circle is so strong that nothing can escape—it sucks in everything, even light. That’s why it’s black!
Do you age slower in a black hole?
As you get closer to a black hole, the flow of time slows down, compared to flow of time far from the hole. (According to Einstein’s theory, any massive body, including the Earth, produces this effect. Near a black hole, the slowing of time is extreme.
Can you create a black hole?
Scientists have therefore started creating artificial black holes inside labs to study their properties. And one such experiment, carried out by scientists at the Technion- Israel Institute of Technology, has proved that Stephen Hawking had been right about black holes all along.
Is an hour in space 7 years on earth?
The first planet they land on is close to a supermassive black hole, dubbed Gargantuan, whose gravitational pull causes massive waves on the planet that toss their spacecraft about. Its proximity to the black hole also causes an extreme time dilation, where one hour on the distant planet equals 7 years on Earth.
What happens to spacetime inside a black hole?
Black holes are so massive that they severely warp the fabric of spacetime (the three spatial dimensions and time combined in a four-dimensional continuum). For this reason, an observer inside a black hole experiences the passage of time much differently than an outside observer.
How do black holes affect space-time?
Spacetime. Similarly, the black hole has created stable deformations in the fabric of spacetime that affects matter moving around it. Gas swirling around the black hole acts like the record needle, but instead of producing specific sounds, it produces certain frequencies of X-ray light.
Does space/time exist within a black hole?
From the outside, the black hole is infinitely extended in time, but has only a finite size in space. Inside, the tables are turned: Time is only of finite extent (it starts at the horizon and ends abruptly at the singularity-axis), but instead one space direction, the axis direction, is now infinitely long.
Do black holes consume space?
Black holes can consume objects like planets, stars or galaxies but not space itself. The gravity of a black holes is likened unto a wave where space-time is the medium. The wave can not consume the medium but rather use it to meet its purpose.
