  • Your understanding is correct.
    Relativistic mass increases the faster the moving object gets. That in turn means more energy is required to accelerate an object the closer it gets to the speed of light.

    Fun fact: the speed of light is not as absolute as it might seem when looking at relativistic effects. In media with a refraction index above 1 (only perfect vacuum has a refractiom index of 1), the speed of light equals 1/(refraction index).
    For light moving in water that results in a speed of light of around 3/4 the speed of light in vacuum.
















  • That’s another viewing angle coming to the same result :)
    But even before Fcbook purchased Whatsapp, it’d have been the worse choice than Signal.
    Nowadays Whatsapp is a very bad choice in a lot of ways except for network effect, which is the only real strength of it.
    Speaking of network effect: back when Signal was TextSecure, I could message a total of 2 (two!) contacts with it and the UX was far from being awesome.
    Signal has come a long way. The UX is great and I can message a lot of my contacts on Signal now.
