Sorry jigger, you have a good head on your shoulders, and are thinking critically, which is just...awesome.
Your not understanding a couple of things though, which isnt a failing on your part, just not part of everyday life in your day.
Time is relative, to the person, and the person observing him, the speed of light is absolute, in all situations, where as I cannot go 99/100 the
speed ofnlight and shoot a light ray that now onky goes 1/100 the speed of light faster than me. Instead, it would leave me going the exact speed of
light, which is a constant in a vacuum, and unchangeable.
So if I travel 1 mph, and shine a flashkight straight in front of me, it does not go C, (C is the speed of kight in physics and math btw) plus 1 mph,
it still goes the exact same speed C, yet it was C for the observer, and C away from me. Meaning my time dialated and slowed my time relative only to
Also time dialatikn is real and exactly measured in relation to gravity and velocity, it is even used by us todY, google gps and how it works, this
will provide a better explanation than I probably can, I am not a very patient or apt teacher, I am the doing type.
So if your astronauts left earth at C for 25 light years out, and came the same back, 50 years would havenpassed here for us, but jot for them.
Time woukdnt have changed for us here as we were still at rest relative to the astronauts, it is their time relative to them that slowed.
Outside the ship, watching it fly by, time would move normal for you, inside the ship time would move normal for the crew, when the inside of the ship
was observed from someone outside it, everyone inside would be moving in super slow motion.
If the ship started out at normL speed and acceleratex, the closer the ship got to light speed, the slower everyone and everything inside would appear
to go, inckuding bread molding, rust forming water dropping etc.
On the inverse, to those on the ship, everything outside would be moving in fast worward, like watching a time lapse video.
Think of it this way, tye SR-71blackbird doesnt carry anyweapons, as all the weapons of the time wouldnt be able to fireas bullets can onky go X fast
, and the speed of the plane wouldnt let the bullets even leave the barrel. As just befUse I can throw an 80 mph fast ball, doesnt mean I can ride in
a pick up bed at 80 and now throw it 160, it wouod onky go 80, as I am still in the stopped air, but if I am in a bus, where the air around me
relative to the stopped air outside was motiknless for me was actually moving 80 also, so I coukd then throw it 80 inside this reference framme, as it
is removed from the outside, thus relative to the inside only.
Hope this helped, if jot ask phage, ge has the ability to explain these kinda things better than I.
