What does zero volume mean in physics?

2
00:00:03,440 --> 00:00:07,940
Well, I guess I would answer that by looking at how Stephen Hawking and Roger Penrose,

3
00:00:08,060 --> 00:00:11,500
when they developed the space-time theorems, recognized there was a singularity.

4
00:00:11,920 --> 00:00:17,140
That when they were tracing the trajectories of particles back in space and time,

5
00:00:17,640 --> 00:00:21,620
that they all came to a point where they coalesced and the laws of physics broke down.

6
00:00:21,880 --> 00:00:26,060
And so, what exactly the nature of the singularity is a little bit unknown,

7
00:00:26,060 --> 00:00:29,860
but it's a sign that the laws of physics broke down, and that's what they said.

8
00:00:29,860 --> 00:00:30,700
Looked like a beginning.
