The events he probes last for about 100 attoseconds, or 100 quintillionths of a second. For a little perspective, 100 attoseconds is to one second as a second is to 300 million years.
Planck time—the smallest unit of time that has any physical meaning—is 10^43 second, less than a trillionth of a trillionth of an attosecond.
The problem, in brief, is that time may not exist at the most fundamental level of physical reality.
“The situation is so uncomfortable that by far the best thing to do is declare oneself an agnostic.”
“It is an issue that many theorists have puzzled about. It may be that the best way to think about quantum reality is to give up the notion of time—that the fundamental description of the universe must be timeless.”
