Which doesn't mean he stops attempting to explain it. It breaks less to say that increasing potential energy requires energy.

"What... is this place?" Curiosity looked around inquiringly. "Unused space? By the way, have you seen Power?"

He also says that he explains stuff in a way that doesn't break physics. What intelligent force manually requires more energy to jump 100 meters as compared to 1 in our world?

How does it need to be calculated? You have a startpoint and an endpoint. The amount of energy required to move something through that portal (assuming it is a portal, which we still haven't confirmed) would be the amount of potential energy needed. Because doing otherwise would break the laws of thermodynamics which Brandon has said he tries to avoid in his books: Because potential energy can't come from nothing if the laws of thermodynamics apply, which they do.

By taking investiture and using that to travel. It wouldn't, but it would require more energy when something travelled through it. Opening a portal for a very brief time to pull people into the Spiritual realm, then opening another one to pull them into the Physical realm at Roshar is still a portal.

Source? Not a legitimate source. That's total speculation. I'd say its a much safer bet to say it worked more like the Oathgates.

No, there was an image in one of the books of humans walking through a portal. I think it was in either OB or RoW. Not sure if it's just artistic license, but the picture does exist.

Did you miss the part of the WoB that said "A Bondsmith can access a lot of power"? That portal required a ton of Investiture, which compensated for stuff like potential energy differences.

Did he specifically say that entropy did not increase in Atium's renewal? Because an equally probable explanation if he did not is that the inefficiency is merely not great enough to be immediately noticeable. Source that they can make portals like that?

Just because Brandon didn't mention Investiture entropy in-book doesn't mean it doesn't exist. That's an argument from silence.

The Investiture that was converted into energy will not return there, it will follow the normal laws of entropy. So even if the cycle is very efficient, it would eventually run out. It might take billions of years or longer, but we don't have evidence to believe it would do otherwise.

The Dor has been powering multiple magic systems for even longer, and it hasn't run out. The spirits are leftovers from Virtuosity's splintering, not to mention that gathering them all together probably opened a perpendicularity that allowed access to the greater mass of Virtuosity's investiture in the SR. Look at it this way: Stars can burn for billions of years, outputting staggering levels of energy all the while, and yet we don't call them perpetual motion machines. 2,000 years is too short a time to conclusively extrapolate to infinity.

Where's the evidence that the Father Machine simply didn't "use up" the energy of the spirits?

Granted. The resolution is you joining the Ghostbloods and giving them vital information, betraying the Knights Radiant. I wish for the intelligence to come up with good ideas.

Granted. Your spren’s mission includes a directive to kill you. I wish that I could be slightly less stressed.

Small price to pay. Granted. Your spren gains memories that include a previously forgotten life as a member of the Ghostbloods. I wish that Brandon would secretly write a bunch more books.

Granted. @The cheeseman swallows Yelig-nar and gains unimaginable power along with immortality for some reason, and your spren loses all of its memories. I wish for Tress of the Emerald Sea to get an incredible movie adaptation that all my non-Cosmere friends will love.

A figure appeared beside Shadow and Michael. "Where are we? I'm Curious." @Thaidakar the Ghostblood

I mean, yeah, that would be great. Brandon and his team might not want to get questions from here, but I'd love it if they decided to.

Nameless steps back from the fool's blade, floor beneath his feet cracking further as he retreats across the room. "When indeed. Honestly, the entire building should have broken apart by now, not just the floor." He points his blade, and a beam of light shoots from it towards the fool's chest. "That would make fighting a bit more interesting."

Not really. It's probably just hyperbole.

The point was never to survive. With how many Koloss there were, it wasn't possible to survive. The point was to burn the Atium away before Ruin could get to it or figure out what was happening, and for that a charge worked best.

You can make anything, but complex substances are more difficult.

If we're still talking about what spren we'd be, I would be a Cryptic and bond @Frustration so we could figure out how combat Soulcasting works.

At least I got to explain the game too.
