Why have we ruled out the possibility of finding something faster when we’ve only scratched the surface of space exploration and understanding?

I want you to forget about speed for a minute. Lets talk about time. Look at your clock or a watch, its moving forward. You are traveling through time! Pretty cool huh. Well this weird thing happens with time, it turns out time is not just kinda weird, its super weird. You and I see time the same way, things are happening at the same speed and such, but when you start moving faster (ok we’re back to speed a little), time starts moving slower. There is a relationship between speed and time. More speed, less time.
Yeah, but you’re gonna say, no, I live here, time doesn’t move slower, and you’d be mostly right. This isn’t noticeable to us because for it to start to be really noticeable you need to be going a lot faster, like on a spaceship.
Now the faster you travel, the slower time goes. Think of it like a line or curve on a graph, the faster you go, the line edges slower in time…it gets slower, and slower, and you keep going. But what happens when you go so fast, that time goes to 0 on our graph? You go so fast, you hit a point where you aren’t traveling through time anymore? Fucking weird right? I’m telling you, that there is some point where something can go so fast that time stops for it? Yes. Thats is what is happening.
That speed, turns out, is the speed of light. You hit a wall, you can’t go any faster since there is no where left in the time graph to go, you’re at 0 it ends there.
This is how you should think of it from an easy standpoint, the better explanations are far more complex and far more accurate (and in fact there are multiple versions such as one from particle physics that is quite accurate, but explained completely differently!), but this is a good way to conceive one method of seeing it
