It's roughly the amount of kinetic energy in a single grain of rice if you gently throw a handful of them. It's not much, but it's not an inconceivably small amount of energy either.
Comparing it to a phone charge is less useful because batteries store a lot of energy (especially when converted to kinetic energy).
- amluto 5y agoI would say that 1.4 PeV is enough energy (by a large margin) to be audible. If that photon interacted with something near you and deposited any respectable fraction of its energy as heat or kinetic energy on a macroscopic scale, you would hear it!
- ganzuul 5y agoPerhaps it would sound something like the house settling.
- raverbashing 5y agoYeah. Wolfram Alpha compares it to (a fraction of - something like 20%) the energy of pushing a key on a keyboard. For one photon to have enough energy to push a rice grain is just crazy. Makes me wonder which physical process created it. Even the hydrogen fusion photon is not that energetic.
