Time indeed does not progress at the singularity, because the singularity as classically described by general relativity is not part of our Universe and time has no meaning.
What happens to time at 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.
Does time exist in a singularity?
The singularity at the center of a black hole is the ultimate no man’s land: a place where matter is compressed down to an infinitely tiny point, and all conceptions of time and space completely break down. And it doesn’t really exist.
What is time like in a singularity?
A timelike singularity is one that is in the future light cone of some point A but in the past light cone of some other point B, such that a timelike world-line can connect A to B. Black hole and big bang singularities are not timelike, they’re spacelike, and that’s how they’re shown on a Penrose diagram.
Does time stop in a black hole singularity?
Near a black hole, the slowing of time is extreme. From the viewpoint of an observer outside the black hole, time stops.Inside the black hole, the flow of time itself draws falling objects into the center of the black hole. No force in the universe can stop this fall, any more than we can stop the flow of time.
Does a black hole have infinite gravity?
Myth: black holes suck everything in
unless you plan on travelling VERY close. Why? Well, even though black holes are extreme in many ways, they don’t have infinite massand it’s mass that determines the force of their gravity.
Does a black hole have infinite mass?
It’s all for the formula: density in a black hole is mass divided by volume (0) so the density is infinite, not the mass!!! So thus a black hole has mass which is finite and will always be finite.
Is time finite or infinite?
As a universe, a vast collection of animate and inanimate objects, time is infinite. Even if there was a beginning, and there might be a big bang end, it won’t really be an end. The energy left behind will become something else; the end will be a beginning.
How was time created?
The measurement of time began with the invention of sundials in ancient Egypt some time prior to 1500 B.C. However, the time the Egyptians measured was not the same as the time today’s clocks measure. For the Egyptians, and indeed for a further three millennia, the basic unit of time was the period of daylight.
What is a white black hole?
A black hole is one prediction of Einstein’s theory of general relativity. Another is known as a white hole, which is like a black hole in reverse: Whereas nothing can escape from a black hole’s event horizon, nothing can enter a white hole’s event horizon.
Is a black hole really a singularity?
In the real universe, no black holes contain singularities. In general, singularities are the non-physical mathematical result of a flawed physical theory.A singularity is a point in space where there is a mass with infinite density. This would lead to a spacetime with an infinite curvature.
What happened to the singularity from which the universe has started?
The Big Bang theory says that the universe came into being from a single, unimaginably hot and dense point (aka, a singularity) more than 13 billion years ago. It didn’t occur in an already existing space. Rather, it initiated the expansionand coolingof space itself.
Is a singularity infinitely small?
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.
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.”Special Relativity pertains specifically to light. The fundamental tenet is that light speed is constant in all inertial reference frames, hence the denotation of “c” in reference to light.
Is interstellar time dilation possible?
Time dilation is real!In Interstellar, the major plot points surrounding time dilation are the difference between time passing in two different locations, where the astronauts sitting near the black hole felt time passing at a slower rate than their families back home on Earth.
Does gravity affect time?
Yes, time goes faster the farther away you are from the earth’s surface compared to the time on the surface of the earth. This effect is known as “gravitational time dilation”.The stronger the gravity, the more spacetime curves, and the slower time itself proceeds.
Can a wormhole exist?
In the early days of research on black holes, before they even had that name, physicists did not yet know if these bizarre objects existed in the real world. The original idea of a wormhole came from physicists Albert Einstein and Nathan Rosen.
Why did the singularity explode?
The initial singularity was the gravitational singularity of infinite density thought to have contained all of the mass and space-time of the Universe before quantum fluctuations caused it to rapidly explode in the Big Bang and subsequent inflation, creating the present-day Universe.
Do all black holes have the same density?
The mass M of the black hole is the same number for all observers. However, the volume V is observer-dependent, and can even be undefined in some coordinate charts. Hence there is no way to unambiguously define the density of a black hole.
What did Einstein mean when he said that gravity warps space?
the curvature of spacetime
Gravity is the curvature of spacetime
It is here that Einstein connected the dots to suggest that gravity is the warping of space and time. Gravity is the curvature of the universe, caused by massive bodies, which determines the path that objects travel. That curvature is dynamical, moving as those objects move.
Do black holes divide by 0?
A Black Hole has zero size. Density is mass / volume. Since volume is zero, the density of a Black Hole singularity is infinite because you divide by zero.
