not really, time existed before humans and will exist long after we are gone.
those are not laws, those are units. Most units do a have human bias. We measure things in meters, seconds, and kilograms, which is no surprise as these are scale of things that humans are accustom to dealing with. Any intelligent aliens encountered will likely use a somewhat different unit for time, length and mass. There are however, natural units which are not dependent on humanity, which any sufficiently advanced race would agree on. We don't use these units in our ordinary lives because most of them are either way to small or large to be useful. The plank time is something like 5x10^(-44) seconds. It would be very weird to say to someone, "I'll call you back in 150,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 plank times", instead of "I'll call you back in 5 minutes".

would like to see that equation if you know it

in the following diagram, the units are cooked up so that space is in units of 1 light second, and time is 1 second. Light travels 1 light second per second, and since the speed of light is a constant for all observers, it always travels on lines of slope 1 (45 degrees). Space is being represented as a single dimension, so we are only considering movement in a straight line (this is a limitation of 2d graphs).

In our story there are several friends who are at rest at time = 0.
Friends:
Bob, Dave, John, and Sue

Bob, and Dave will be at rest the entire problem, so they travel down the time axis. Time moves forward for them, but they don't move in space. They are represented by the purple arrow that is on top of the time axis.(slope 0)
Bob and Dave have an agreement, after 3 seconds, Bob is going to emit a flash of blue light. (blue line). This will be a cause.
Dave has agreed that when he sees the blue light, he will wait 2 seconds and emit a flash of green light. (green line) This will be our effect.

John will be taking off on his rocket ship 2 seconds after the start of the graph. His rocket ship quickly accelerates to 1/2 the speed of light then just coasts along at that speed. So in 1 second he travels 1/2 a light second. So he will travel on a line of slope 1/2. (orange line)

Sue will be taking off on her rocket ship after 6 seconds. Her rocket ship is a magical rocket ship that quickly accelerates to 3 times the speed of light then just coasts along at that speed. So in 1 second she travels 3 light seconds. So she will travel on a line of slope 3. (red line)

Bob and Dave see the blue flash and the green flash, and agree that 2 seconds took place between them.

John sees the blue flash first, and later sees the green flash (cause first, then effect later). An interesting side note: You will notice that while John still agrees with Bob and Dave on what was the cause, and what was the effect, he will disagree on how much time took place between them. John experiences more than 2 seconds between the flashes.

When Sue takes off on her rocket ship, she sees the green light first, and the blue light second, the effect before the cause. On a side note: she experiences less than 2 seconds between the green light and the blue light.

You will find that if you add any observer at any speed less than light (slope less than 1), who sees both flashes of light, they will always agree with each other that the blue flash came first, and some time later, they saw the green flash. They will however disagree on how much time transpired between flashes. Observers that travel slower than light always see causes before effects.

You will also find that if you add any observer at any speed greater than light (slope greater than 1), who sees both flashes of light, they will always agree that the green flash came first, and that some time later, they saw the blue flash. They will however disagree on how much time transpired between flashes. Observers that travel faster than light always see effects before causes.

interesting but i dont really find that to make sense. maybe im just ignorant but say something took off after 6 seconds on the same slope as sue (red line) traveling 1/100th the speed of light. they will certainly see the green light first, which would be the cause... and later they would come to the blue line, or effect..not making sense to me. what am i missing?

also if sue was traveling x3 the speed of light she wouldnt even see the green flash ?

oh, remember the slope is determined by the speed! So someone can't use Sue's slope if they aren't using her speed.

/e Sue's slope is 3, that means she is traveling at 3 times the speed of light. If someone was to travel at 1/100th the speed of light, they would be traveling on a line of slope 1/100th, and if they did this a time=6, they won't see any of the flashes (as they are in the past).

Yes, the inked I used is stored into the paper, but everything that was going on when I was writing stuff on paper, all around the world, wasn't recorded anywhere. It just happened, that's all.

regardless what the slope is if you take off anytime after the green light flashes it is impossible to see the blue light before it unless you could travel faster than light to get above the green one and go over to the blue before the green one got to you... you cant be to the right of the green line (take off after it) and see the blue before it.. you would have to go through the green to see the blue.

Actually it was recorded. Say 2 rocks colliding in a wave on a beach. A record is made of this collision. The rocks have defects, a sound is produced, heat is generated by friction and photons are released. Very similar to what happens when the paper with the info on it burned. The information is not destroyed, but it is defused to the point very quickly where reconstructing the information is no longer viable.

exactly right! If you take off after both flashes it is impossible so see either one, unless you go faster than the speed of light. In which case you will always see the green one first and the blue one second. When you travel faster than light you will always see effects before causes.

If time travel is real (Going into the past)

We could interact with ourselves in the past, or kill yourself.

Once you killed yourself, what would happen...?

If time travel (Into the future) is real

We could see our self in the future, therefore creating two of the same person

But if you went into the future, your future self would have also gone into the future at the exact time

So some type of weird ass loop full of some loops is created.
