The Paranormal, UFO's, and Mysteries of the Unknown

Forward time travel as normally seen is probably impossible, but on an individual level if you can place the body in uninterruptible stasis without effect on the body, the individual wouldn't be able to tell the difference between it and instantaneous time-travel.

Forward time travel is easily possible, because the passage of time is relative. Has nothing to do with stasis. It does have to do with moving very fast.

A traveler leaves Earth to go to a planet 9.5 light years away. They travel at .95c, or 95% the speed of light.
An observer from Earth watches them leave and arrive. To them, it takes to observe 10 years for the trip.
For the traveler, it took 3.12 years.

now, if it was say 2100 that the traveler left, it is 2110 when they arrive, but they will have only aged 3.12 years.

Reverse time travel is not possible, because the speed of light, is not really the speed of light.
The speed of light is actually the "speed of causality". The speed of cause and effect. Everything caps out at that speed. Reverse time travel, would break Causality. and Causality is the single most fundamental aspect of the universe.

That's not time travel lol. It's still the same year for both the observing party and the traveling party. It's still the same moment of time.

If I open a door, walk through said door, taking 3 seconds, and during that transition, 10 years have passed to everyone else. how is that not time travel?

First of all, that would never and could never happen. Second of all, what you're claiming is that it only seems like it took 3 seconds when it actually took 10 years but merely felt like 3 seconds.

No, not joking. No clue how they gain inertia :/

Inertia is the property of matter to remain unchanged, unless acted on by an external force.

This is probably directly tied to causality. Objects at rest tend to stay at rest. The default setting of everything.
If, then.

If an external force interacts with an object, this causes a reaction. Atom, by atom. Cause then effect. An "inertial dampener" would have to somehow, cause every atom within an object, be it passenger, spaceship, etc to be effected at the same rate, at the same time, by any external force.
When you hit the brakes on your car, YOU don't stop, your car doesn't even stop, the wheels don't stop.
what does stop, is the surface of your brakes as they have fricition with the brake pad surface. the surface of the brakes, then slow/stop the brakes, then wheels. AS the surface of the wheels then stop with friction with the road surface.

And yes, this opens the big question. If, the universe is a closed system. AND, Causality requires CAUSE then effect. AND, the fundamental state of everything is AT REST.
What the fuck caused the big bang? By our understanding of reality, it HAD to be an external force.

I would have literally only aged 3 seconds. Half life of radioactive materials would have only aged 3 seconds.

Time is an illusion of cause and effect.

You can stop right there and bingo, you're starting to get it! Time doesn't actually exist. And therefore, we can conclude that time travel doesn't either.

Let's do the same exercise but with more extreme numbers.

Say you're headed to a star 10 light years away, you leave tomorrow, and you travel there at 0.99999c.

If you watched the clock the whole time, you'd see a mere 16 days pass. If you marked an X on the calendar for each day you see pass by, you would think it was December 1st, 2018. But if you checked with anyone when you got out of your space ship, they'd tell you it's November 15th, 2028.

You're only two weeks older, but everyone else is 10 years older.

You wouldn't say that from YOUR perspective you time travelled? Why, because it took two weeks and wasn't instantaneous?

Again, what you're claiming is literally an impossible scenario that will never and can never occur. Regardless, the same amount of time is still occurring for you as it was for everyone else otherwise how the fuck are you arriving at the same moment of time as everyone else? Either way, your example is not even possible in reality regardless so I'm not sure what your point even is.

Maybe not possible. The Tipler cylinder - Wikipedia mathematically works out and would be a mechanism to travel into the past.

If I am reading that correctly. what its basically saying is, time travel is theoretically possible... if you create a bubble universe where the laws of physics are different then ours, then you could create time travel inside that bubble.

only Lumi could be this dense.

Pretty sure it's you that's dense my friend. What you are saying doesn't make any sense at all. Your example states that you can somehow travel to a star 10 light years away traveling at .99999 the speed of light and some how arrive there in 16 days(lollll????). In order for this to be possible, you would've had to been traveling at roughly 228x the speed of light. Even your own example makes no fucking sense whatsoever and you say I'm the dense one? Bro, I think you need to stop with that chemo shit because it clearly fucked up your already damaged brain.
