* Quintillion: A quintillion is a very large number represented by a 1 followed by 18 zeros (1,000,000,000,000,000,000).
* Quintillionth: This means dividing one second by a quintillion.
To give you an idea of just how small this is:
* Planck time: The Planck time is considered the smallest unit of time that has physical meaning, approximately 5.39 × 10⁻⁴⁴ seconds. A quintillionth of a second is still much larger than Planck time.
While we can represent a quintillionth of a second mathematically, it's difficult to conceptualize its actual duration in relation to our everyday experience. It's a time scale far beyond our ability to directly perceive or measure.
