- the initial singularity
- edge singularity
- the problem of singularity
But it's because he had found these singularities, these infinities.
- But it's because he had found these singularities, these infinities.
- Now we can't really predict what happens at the singularity because Einstein's theory breaks down.
- That's why physicists think The Big Bang singularity just tells us that we need a better theory.
- You said that quantum loop gravity does away with singularities.
- Well, this was a temporal singularity.
- This is because the way that Karl Schlotzscher originally wrote down the mathematics of black holes, there is indeed singularity at the horizon.
- I guess simple way to think about it is you create an object with zero radius that has mass but zero radius singularity.
- White holes are singularities in space, but The Big Bang is an expansion of space itself, right?
- From this point of singularity, everything began to expand and it continues to expand today as far as we know.
Examples
-
This is called a singularity, and the gravitational attraction it exerts is so powerful that nothing, not even light itself, can escape.
-
Now we can't really predict what happens at the singularity because Einstein's theory breaks down.
-
You sort of thought originally that the singularity was a place.
-
We know pretty well how it is, and the singularity is not at the centre.
-
That changes how we understand the initial singularity.
-
From this point of singularity, everything began to expand and it continues to expand today as far as we know.
-
But it is also understood that such a singularity is merely apparent and not real.
Academic text (2005) -
According to the general theory of relativity, a singularity represents a boundary to space and time.
Academic text (1992) -
Now it is theorized that a fusion reaction with sufficient mass could create a singularity.
-
The mathematical model predicts that a singularity occurs at the center of a black hole, where gravity is infinitely strong.

Etymology
The word singularity comes from the root singul- meaning 'single' or 'one', the same root as single. In mathematics and physics it names a 'single point' where the normal rules break down, which is why the centre of a black hole is called a singularity.
