so imagine this scenario. you are in a ship that can travel at light speed if it wants to, and you need to reach something thats exactly 1 light year away. so from your perspective, it will obviously be the best to travel at max speed and get there in a year

but! imagine theres a device at the end of your trip that loses fuel as time passes. you need to get to it as fast as you can. so if you go too slow, the device will lose fuel before you get there, but if you go to fast, you will travel through time much more than space and from the perspective of that device, too much time will have passed even though it took you 1 year, yes :unsure:

? so is there some sweet spot speed you should go at, or just the faster the better?

its okay if you dont understand the question, neither do i :mellow:

but i need some input

edit:

i mean if space and time are simply 1:1 on that total speed thing, then i guess the best possible speed would be 300000km/h divided by square root of 2, but i assume its not that simple now is it :cry:

?

The math is much more complicated than x+y=300000 kph

anyways, so whats the answer to my question :unsure:

? whats the speed someone has to go at, to arrive at the end point with the least time lost from the perspective of the destination :unsure:

Dig into the math and figure it out. If you're too lazy to use Google why would I bother holding your hand through a complex problem? You aren't really interested in learning.

well i dont blame you ^_^

if im too lazy to go through the math even though its my question, why should you bother when you have even less incentive

anyways, if we have some theoretic physicist or something in the ballpark on this forum, pls save me an hour of reading and tell me the result :cry:

edited my supreme grammar :cry:

They make up this

Theory is not a fact

This theory supports the big bang theory, which supports the theory of gravity etc.

These concepts sound good but are not correct.

The constant for acceleration free fall was well known before the theory of these Jewish freemasons dominated so called sciences

Take note and watch any time lapse video of the stars. [North Polaris has the most beautiful views, shows you the stars move like a record player around us]

They are not twisting and doing all these ridiculous things that you would see on a helicentric model, instead you see a beautiful celestial dome.

Enjoy

so this has been bugging me since i was a kid

basically, everything travels 300 000km/h through both space and time at once. if we travel faster through space, we travel slower through time, meaning time passes faster for the observer :wacko:

so imagine this scenario. you are in a ship that can travel at light speed if it wants to, and you need to reach something thats exactly 1 light year away. so from your perspective, it will obviously be the best to travel at max speed and get there in a year

but! imagine theres a device at the end of your trip that loses fuel as time passes. you need to get to it as fast as you can. so if you go too slow, the device will lose fuel before you get there, but if you go to fast, you will travel through time much more than space and from the perspective of that device, too much time will have passed even though it took you 1 year, yes :unsure: ? so is there some sweet spot speed you should go at, or just the faster the better?

If you are interested in this topic, check out PBS space time channel on youtube: https://www.youtube.com/c/pbsspacetime

They have quality videos on topics and dilemma such as you propose, but actually work them out with visuals, or thought experiments.

Video on this subject:

the videos do seem to be really well made though :blush:
