  • You are correct that if you are on thee moon and have a cs-133 atom with you is second will take that many transitions. And if you do the same thing on Earth, a second will take the same number of transitions.

    But things get weird when you are on earth and observe a cs-133 atom that is on the moon. Because you are in different reference frames, you are traveling at different speeds and are in different gravity wells time is moving at different rates. This means that a cs atom locally will transition a different number of times in a second from your point of view on Earth vs one you are observing on the moon.

    And it would all be reversed if you were on the Moon observing a clock back on the Earth.

    They already have to account for this with GPS satellites. They all have atomic clocks on them but they don’t run at the same speed as clocks that are on the ground. The satellites are moving at a great speed and are further from the center of the earth than us, so the software that calculates the distance from your phone to the satellite have to use Einstein’s equations to account for the change in the rate of time.

    Relativity is weird.




  • I think there is a distinction of PUSH advertising where you see billboards everywhere, ads stuck into youtube videos, spam emails, whatever that is just sent out to the general public and see what sticks. Compare that with PULL advertising where a consumer goes out and looks for something. When I am shopping for a new TV or something that needs a bit of research, I have no problem being sold to.

    It’s kinda like going out of your way to watch movie trailers. Or watching a lets’s play of a video game you are interested in. It can be a fun way to spend some time and they can be entertaining in their own right.


  • I don’t know, I feel like advertisements CAN be entertaining content, much like how people for decades have only wanted to watch the Super Bowl for the commercials. The problem, and the reason I have ad blockers all over the place, is that they don’t design the commercials to be entertaining. They want to drill it in to you with endless repetition, or banner ads every 2 paragraphs on a news article.

    It is these problems that cause me to want to block ads, not ads in general.
