1.4 PeV are about 0.224 millijoules or roughly an 8 billionth of a phone charge, so not much really. However, the photons we usually deal with are weaker by an unimaginable amount, but also much more plentiful. For example, a 100 W light bulb emits something in the order of 10^21 photons per second. If you had a light bulb that emitted the same amount of photons with 1.4 PeV each, you'd have a device equivalent to one Tsar bomb (the most powerful bomb ever detonated in the history of mankind) every second.
- contravariant 5y agoIt'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.
- adhesive_wombat 5y agoThat's a big old phone battery: 8 billion times 0.2mJ is a 120000mAh 3.7V battery. But yes, it's in that ballpark and it's a loooot of energy to pack into a proton.
- teraflop 5y agoPresumably the parent commenter meant "8 billionths", not "one 8-billionth".
