Keep in mind that if you could travel at lightspeed the journey from the perspective of the traveller would be very quick due to the time dilation they would experience, same goes for visitors to our planet if someone somewhere created lightspeed travel
Thats technically the truth, since the closer you get to lightspeed the more time is not perceived.
Every Object that is massles instantly hits lightspeed as told by e=mc², if you form the formulate to calculte "the root of c²= the root of e/m" if you put in 0 for mass you get infinity, so technically you get c=infinity, which is not possible and it stops at the fastest possible speed. In other words you couldn't accelerate anything with mass to lightspeed because the energy needed to approach it, is so huge.
Sadly that part is not even doable. Because since you are always dividing by something you would need infinity energy which divided by something is still infinity.
And yes, the faster you go aka the closer you get to light speed the slower you perceive the time around you, but for you a year is still a year. The world around you just runs at a different speed in time. Thats the mind boggling part of the Theory Of Relativity. It took my way to long to understand that bullshit and i still don't entirely get it since its contradicting our everyday logic. The Time outside your spaceship would still go as usual. Nut I still have no understood it entirely and probably have made some errors.
IIRC it's because the speed of light is constant to all observers regardless of their relative speed. Like if one person is "not moving" while another is traveling at 50% speed of light, relative to a photon of light, that photon will still be traveling at 100% the speed of light to both of them.
Which wouldn't make sense, it's like you're driving 40mph down a highway, see someone going 60 mph in the same direction, they'd appear to be traveling 20 mph relative to you right? But nope they're still going 60mph. The only way this is possible is that time slows down for the observer traveling at 0.5c
Been a while though so I'm not sure I'm right either
