Wait, dumb question. In a vacuum can I go as fast as I want. Like as long as acceleration is cool. Is there technically no downside to increasing speed. Just like we're technically on a planet spinning fast. If I was in a ship in a total vaccumu and it accelerated at a pace that I could handle, could that ship go faster and faster like a bajillion km a sec and I would just be like sitting there enjoying the ride.
From your perspective, eventually things don't move faster by a noticeable amount, but the length of objects starts to shorten, so you can pass much more stuff at a slightly faster speed. You will never see anything move faster than light, it just shortens itself into a 2d object with 0 depth as it approaches the speed of light.
So not a bajillion km a sec, just 300,000 km/sec
But then there is no limit to how fast we could move? Like there is no speed our heads would explode. There's no side effect of speed I guess is what I'm asking. Like 2x speed of light would be no different to us then 5km/hr. Sounds like the only thing would be stuff external to us like the length getting shorter. I get in atmosphere we'd be shredded. But technically we can just go.
Yes, movement is undetectable unless you have something to track your movement against. In fact, there's no way to define "staying still" that's true for everyone in the universe.
You can only feel acceleration, not constant speed movement.
2x the speed of light is impossible. As things move faster, time slows down so they can't make as big of a change to their movement speed using the same amount of energy. Instead, lengths contract so your destination doesn't appear to be as far as it would have been at the start of your journey.
Awesome thanks for all the information.
Here is my take away, speed is not real. Its a concept created by Big Relativity.
Just mindblowing to me that speed does have no effect on us under certain conditions. Like learning that pregnancy can work in zero G. As if we are star people not just Merpeople from the ocean.
Yeah I'd suggest looking at frames of reference and how time dilation keeps the speed of light constant or in other words special relativity.
Technically, you can do this in the air too. The air just needs to be moving at the same speed you are.
