Hey, I don't mean how wide the black hole looks from the outside, but rather… how long could a photon travel at the speed of light beyond the event horizon if it were moving directly toward the center? So, how much "stretched" space is there? Surely that can be calculated? At least hypothetically, assuming there's…
Hello everyone, I need help with this problem, preferably with a solution. Thank you in advance for your help.
Hi, I have an old alarm clock, a Kundo 2000 to be exact. The alarm clock is probably about 30-40 years old. Well in any case the transformer is always quite warm. Well, it's not hot or anything, but it's still quite warm. What could be the reason for this? Is it perhaps due to…
Hello, My phone can be charged with up to 15 watts. There was no charger in the box. Now I have several adapters at home. I have two 15-watt ones. But there's a slight difference. One has 5 volts 3 amps = 15 watts And the other one has 9 Volt 1.67 Ampere=15 Watt So…
Hello first of all, I wanted to build a PV charger myself so that I can charge my 18650 batteries and then use them to power COB LED strips. I have 4x 2.5W 5V solar panels for a total of 10W. I have enough TP4056 boards with overcharge/undercharge protection, 6x 18650 4.2V battery cells from…
So, purely from a physics perspective, catching yourself quickly, say, 1m above the ground after a fall from 50m isn't that different from hitting the floor a second later. You'd actually have to slow your fall, bungee-style, before stopping the apple from hitting the ground. I think that's portrayed incorrectly in so many films, sometimes…

Thank you.
