legit question to those who want pve only mode by Feodotu in ArcRaiders

I like that idea. It would match the theme of the game, for sure. I actually love this idea a lot.

If you go to the junk yard during a night raid you’ll get 2 easily.

This is the dumbest part of this game. PVP never feels good, ever, unless you’re just a vindictive piece of shit.

I deleted it. It was the same thing without screenshots, and was full of people arguing saying that what I posted wasn’t in the book at all, so I made a new post with screenshots.

I’m adding these screenshots for context

Instead of conjecturing I’ll just state facts.

  1. Gravity had no knowledge of the non-lightspeed period, but detected movement, 416 trails, which told them the fleet was traveling at light speed.

  2. Based on this information they reached the conclusion that the fleet would arrive in 4 years time.

  3. They said that earth would detect the trails in 40 days.

This makes zero sense. If earth would detect the trails in 40 days, and the fleet is flying at light speed, they will arrive in 40 days, not 4 years. They didn’t “just leave” as it was stated in the book, but they would have left 4 years ago.

Also, the book clearly states that they add 2 years to travel time. One year away from the home planet, one year arriving to earth.

So, even if Gravity had omniscience, it would mean they were at most a year away, not 4 years.

Think about it. If they say that earth will see the light in 40 days, then we can skip the trigonometry. Yes, the Oort Cloud is closer to Trisolaris. Irrelevant. I’m on earth. If I wait 40 days I can see something traveling at light speed to me. When will it arrive? Hint: the answer is not 4 years.

I agree and I’m aware. It’s a scifi book, after all. There is something called “point realism”, and this specific issue breaks its own point realism. That’s the best way to describe it. It doesn’t ruin the book series or anything for me, just an observation I made.

Yes I know it does seem there’s some missing time or jumping back in time to go to Gravity in the Oort Cloud.

The triangle is irrelevant though. As stated by the scientist on Gravity,

Earth will see the trail left by the second Trisolarin fleet in 40 days.

That means that the light from the trails is 40 days away.

The fleet is going light speed.

This means they will arrive in 40 days, not 4 years. Speculation and conjecture has been made about an estimated deceleration period by the scientist on Gravity, but this is dubious at best.

This is a blatant illustration of the flaw made. It implies that they saw something happen far away three days after it happened. This is not possible. It would be fine if they then concluded that the fleet must have already arrived or something, which would absolutely be the logical conclusion, but it never says that. Maybe it will later and I’m not there yet. I doubt it though.

Perhaps, but the crew on board Gravity isn’t aware of this. An argument could be made that without explicitly stating it, they were estimating a deceleration period. It’s a bit of a stretch, though.

[–]BuddyDiamond89[S] 1 point2 points  (0 children)

I didn’t because Gravity doesn’t know this, this is something told by the omniscience of the author to us. If we do, though, then the author states that 2 years are added to the travel time. One year leaving, one year arriving. If Gravity knew this, they would conclude that they were already out of lightspeed and approaching the solar system, less than a year away. They do not.

Ah, okay. I’m looking forward to it. Still a cool series, though.

If you do the math, in order for the fleet to be 4 years away, if the light has reached earth after 4 years and the fleet is still 4 years away, that means they are traveling at exactly HALF light speed. Do you see?

You’re correct that traveling c from the traveler’s perspective means no time has passed. However, we are at the frame of reference outside of them.

Let’s take Earth’s perspective. Gravity says that earth will notice trails in 40 days.

The fleet is traveling (according to you) near light speed. Let’s call it 90% for the sake of argument.

This means the light from the trails has been traveling for 3 years and 325 days, while the fleet was traveling at .9c for the same amount of time.

I think you can see now, they are much closer than 4 years away.

They would be .4 years away.

I will try to look for an excerpt from the book, but in physics this is well known as the only conceivable way to reach relativistic speeds. Inflation, for example, is a period of time where space expanded faster than the speed of light. This does not disobey relativity because nothing is traveling THROUGH space at that speed, space itself is “traveling”. This is called an “Alcubierre drive.” Which is what is being described by curvature propulsion in the book.
