High Vacuum vs Vacuum System
1:16:44 - 1:19:40 (02:56)
The biggest vacuum system is at CERN, but the high vacuum where they need really good vacuum is smaller than others. High vacuum measures at 10 to the minus nine torrs, while a vacuum covers a larger range.

The difference between high vacuum and vacuum systems lies in the degree of vacuum needed, measured in torrs.
1:16:44 - 1:18:25 (01:40)
Summary
The difference between high vacuum and vacuum systems lies in the degree of vacuum needed, measured in torrs. High vacuum systems require a pressure of 10 to the minus nine torrs, while vacuum systems refer to a broader range of pressures.

Summary
The creation of bridges from a civil engineering perspective represents the beautiful collaboration of humans using physics to construct objects that can support a massive amount of weight. In contrast, the discovery of the collision of two black holes that happened 1.3 billion years ago occurred while the Earth was transitioning from single-cell to multi-cell life, long before humans were present.
