Ill look into it right away

@Faket .basically if it is moving near the speed of light if it goes towards you it would look near instantaneous, if it moves away then it would move at half speed. This is the same regardless of what the speed limit happens to be so long as it is finite and the bullet is moving near this limit.

@Faket ahh yes, but only when the car is moving towards you ... when you said slower I thought you meant the car looked like it was moving slower in your frame of reference.

@Faket Thats an entirely different and unrelated effect. the bullet appeared to move **faster** than reality (faster than is even possible), not slower. You are thinking of time dilation, which is entirely unrelated to what I'm describing.

@Faket what do you mean, how is it the same for all speeds? If someone is in a car going 100 mph and its a 100 mile ditstance I would see them taking their actual time to get here, an hour for 100 miles, which is quite different.

@Faket no, but if i literally watched him leave his house with my telescope and watching him traverse the entire distance in 10 minutes then obviously I would...

The point is if you watched the bullet as it left the gun and on the entire trip as it appraoched you then you would see it travel an entire light year in only 10 minutes, right before it struck you :)

You know shit is about to get serious when i bust out my 25 kV variable vacuum capacitor.

@johnabs I had considered that though I wasnt quite prepared to do parsec area :)

@rebel_luddite@social.linux.pizza Yup, its the one with hercules :) lol

@mur2501

you scare me sometimes...

@loke

@lucifargundam lol love it...

In this case the ship wasnt exactly inanimate, it had a personification, an avatar as they called it.

@loke

A bit cumbersome, but at least it is precise :)

@mur2501

Interesting fact of the day:

One interesting consequence of the speed of light limitation is that it can actually cause things to appear to move much faster than the speed of light (near instantaneously) while still actually moving no faster than light.

Consider a gun 1 light year away firing a bullet at you very close to the speed of light 0.9999 C or whatever. At the moment the gun is fired it would take one year for the light of the firing even to reach your eyes, so by the time you see the gun firing it has already been a year. At the same time the bullet takes just slightly more than a year (to pick an arbitrary number say 10 minutes longer than a year) to reach you. So after you see the gun fire the bullet would reach you just 10 minutes later. This also means it would appear that the bullet traversed a one light year distance in only 10 minutes. Of course in reality this is impossible and it did not, but it would look that way.

@rebel_luddite@social.linux.pizza its on amazon prime video... this is my first time watching it, it felt too cheesy when i tried in the past but its actually not as bad as it looks now that im halfway through the first season.

As a scientist I have an innate desire to want to use metric measurements. But as an someone born in America I also have a desire to use obscure measurements no other sane person in the civilized world would ever consider using.

As such I have decided that from now on I will use femtoparsecs and attoparsecs for all measurements of length.

I am 57.6 attoparsecs tall

My jeep gets 344 femtoparsecs to the liter

@js290 Everything sounds like a futurama episode :)

@rebel_luddite@social.linux.pizza That would be a good guess, and LEXX is fricking amazing.. but no he never has sex with his ship (though the ship does have sex with a bug at one point)...

No this would be andromeda.

So the Sci-fi show I'm watching right now... the captain apparently falls in love with his ship, has sex with it, the ship gets jealous when the captain tries to get it to self destruct to hide his "shameful" sexual intercourse with the ship, in response the ship blows him up and the entire planet instead against orders.... cant even make this shit up.

I'm all for any scifi that has a captain bonning his ship, cant wait to see what they do next episode.
