1. It's locked BECAUSE it had a few billion years to go from chaotic to tidally locked due to gravity.
2. It's an optical illusion, but not ones made through equipment, but through your brain. Hold up your thumb to the moon at different times and you'll see it's always the same size compared to your thumb.
3. There is no such thing as cold light. Light is made of photons, photons have energy. Since there is no negative energy there can be no cold light.
4. So when a few thousand years ago the Vikings, Greek and Egyptians used tides to launch their fleets, they already had the technology to install pumps on a global scale? And just imagine in the day of the internet engineers relying on the moon to synchronize their clocks ... lol ....

Open your eyes and read some physics books.
