Hi everyone, I am new to this place. I came here to seek genuine criticism, and feedback about a crackpot theory I have.

I wanted to post here a hypothesis/theory I have about going FTL. I call my theory the "Echo Drive", I named it after the Alcubierre drive, although it is fundamentally different. I first would like to say that my theory is what one would call "crackpot", it might seem absurd at first.

Let me start explaining:

The basic idea is that instead of moving a ship through space faster than light, you move the information that defines the ship. Before any FTL travel occurs, we send out probes to distant places in space at normal speeds. These probes are sent to build what's basically a "receiving zone" that's quantum-linked back to Earth. It's like setting up a destination before you literally go there. When we launch a ship, it enters something I'm calling a "decoupling chamber". The chamber pushes the ship into a superposition, so its location is undefined and is not tied to a single location. The destination probes linked to the ship's quantum state and activated themselves so that the ship's state will collapse and reconstruct at the destination. So, the ship basically disappears here and appears elsewhere instantly.

Let me back it up with physics/math:

The drive is completely based on the thought that matter is quantum info. So, we don't have to go beyond c -- we can just pop the ship at another position when its quantum state is in superposition with no exact location.

So, when the ship is in superposition it exists as a wavefunction:

P(x) = |Ψ(x)|^(2)

And since the probes are entangled with the ship, they collapse that wavefunction, so the ship pops instantly into the destination spot set up by our probes.

So, my idea basically avoids any universal speed limit because the ship technically doesn't exceed:

v < c

So, while the velocity of the ship is lower than c, it teleports instantly and allows it on a massive scale without ever going into sail. This "teleportation" is FTL, because the info describing the ship also pops there as well. Since we rebuild the fabric, and the info and teleport it instantly we have officially stepped into the land of FTL.

So, what do you all think about my theory? Does it make sense, is it plausible? Could I strengthen it? What could I improve? Any ideas or contradictions? Thank you for taking the time to read my post. It means a lot!

Hello, everyone.

I am very good at math, but these 3 problems my math teacher gave to me I am unable to solve. I would greatly appreciate it if anybody could help me solve these. Down below are the problems.

Problem 1 - "There are 41 people standing in a circle, numbered 1 to 41. Starting with person 1, every second person is killed in order around the circle (so person 1 kills person 2, person 3 kills person 4, and so on). The process continues around the circle, skipping the dead, until only one person remains. Which person survives and is never killed? "

Problem 2 - "You start with a light bulb that is OFF. For every natural number n=1, 2, 3, …, 1000, you do the following: If n has an odd number of divisors, you toggle the bulb. Otherwise, you do nothing. After completing all 1000 steps, is the bulb ON or OFF?"

Problem 3 - "V + L = 135" (note: idk what this even means, isn't the answer all real numbers?)

I don't understand how to solve these; thank you all for taking time to read my post -- it means a lot.
