  • Because this is a science thread I’ll be a bit pedantic. Mostly because I think it’s an interesting topic. It’s a mass-energy equivalence (≡) and not just an equality (=) they are the same thing.

    So it’s meaningless to say convert mass into energy. It’s like saying I want to convert this stick from being 12 inches long to being 1 foot long.

    You can convert matter (the solid form of energy) into other types of energy that are not solid. But the mass stays the same.

    It’s like when people say a photon is massless. It has energy and therefor mass. It just has no rest mass. So from the photons frame of reference no mass but from every other fame of reference there is mass.






  • Yeah the problem isn’t the ideals being in there but how bad the story is makes the ideals seem like a cheap crutch.

    Compare Brokeback Mountain to Ben and Arthur. Both movies about the relationship between gay men and society. Both say gay people should be treated fairly by socity but aren’t. The first does it in interesting way with great storytelling and ideas. The later is a hamfisted mess.

    I’m not going to say modern Trek is Ben and Arthur bad but it is much closer to Ben and Arthur writing then it is to Brokeback Mountain.

    The other problem is the ship signal they traced would have been frequency shifted by the same amount as the time dilation. They would have had to compensate for that to even detect the signal.

    It was 1 hour : 7 years I think. So about a factor of 60,000. So if a ping was once a second it would be once every 42 days. And if it was a 1MHz transmission it would be at about 17Hz.

    So they somehow realized the once a second 1MHz signal was now a every 42 day 17Hz signal at 1/60000 the power. But didn’t realize that there was time dilation involved.




  • Yeah mid game the cpu load gets bad. Some tips.

    Cleaning up debris into piles to simplify physics calculations.

    Removing gasses you don’t need that are floating around the map.

    Walling off sections of the map with only one door to simplify path planning.

    Killing off or consolidating the wild creatures.

    Setting dups (like cooks) that don’t need to leave your base to not be able to leave.
