What would you see if you were to drop a clock into a black hole while you remained orbiting around it?
We would see no slowdown as we approached the event horizon.
We would cross the horizon without any perceptible change, and our color would not appear to change.
This is the principle of relativity: things can appear different depending on whether you are moving or standing still..
Does time stop in a singularity?
When you hit the singularity of a black hole, time stops for you simply because you’re annihilated. This is similar to what happens at the big bang singularity: any observer would have been annihilated by the conditions of the early universe in which the temperature and density diverged to infinity.
Are black holes?
A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
What stops a black hole from growing?
According to general relativity, the inward gravitational collapse never stops. Even though, from the outside, the black hole appears to stay a constant size, expanding slightly only when new things fall into it, its interior volume grows bigger and bigger all the time as space stretches toward the center point.
How old is our universe?
13.8 billion yearsOur universe is 13.8 billion years old, a timescale much longer than the more relatable spans of hundreds or thousands of years that impact our lived experiences. So how do astronomers arrive at such an enormous number?
How big is a singularity?
A singularity is a single point. It has no extent. A gravitational singularity is predicted to have zero volume and infinite density. However, the predicted singularities associated with black holes are unobservable.
How many dimensions are in a black hole?
Black holes may be two-dimensional, but contain information about three dimensions, just like a … [+] As material falls into the black hole, information would not be lost. Instead, it is preserved in the surface area (or the event horizon) of the black hole itself.
Is a black hole 1 dimensional?
A black hole is more like the former: its entropy output is related to the emitted power as it would be for a one-dimensional channel, and disposal of an information stream down a black hole is limited by the power invested in the same way as for a one-dimensional channel. …
Does time exist in a singularity?
This is what we describe as a singularity: a set of conditions where time and space have no meaning. … Relativity, remember, is the theory that describes space and time. But at singularities, both spatial and temporal dimensions cease to exist.
Can time be stopped?
The simple answer is, “Yes, it is possible to stop time. All you need to do is travel at light speed.” … We know that an object, or a light beam’s, speed measures the distance traversed over time.
What is the smallest particle in the universe?
QuarksQuarks, the smallest particles in the universe, are far smaller and operate at much higher energy levels than the protons and neutrons in which they are found.
How small is a singularity?
“Most likely they are maybe a million million times or even more than that smaller than the distances we’ve seen so far.” That would make singularities roughly the size of superstrings, if they exist.
Do you age slower on the moon?
Yes, but only by a remarkably tiny difference. According to Einstein’s General Relativity, and the “Equivalency Principle equation of Physics, a cesium clock on the surface of the Moon should run about 1/300.000,000 of a second slower than an identical clock here on Earth.
What is the smallest thing in the universe?
As far as we can tell, quarks can’t be broken down into smaller components, making them the smallest things we know of.
Will Polaris become a black hole?
When Polaris runs out of fuel, it will become a red supergiant: A red giant. … If it does not, it will become a black hole; however, in this case, I find this quite unlikely; in all probability, Polaris will end up as a superdense chunk of what was once, before it became one great big atomic nucleus, iron.
