So I Looked It Up
Can Microwaves Turn Waste Plastic Into Useful Fuel?
Turning waste plastic into oil sounds like alchemy. The chemistry is real; the difficult questions are energy balance, emissions, feedstock and what the product actually is.
Wireless Electricity Is Real. “Free Energy” Is a Different Claim.
Power can cross a gap without wires. That is real physics. The rabbit hole begins when a demonstration of transmission quietly becomes a claim of energy creation.
Can a Water-and-Gravity Generator Produce More Energy Than It Uses?
A machine can use falling water to generate electricity—but only because energy first lifted the water. We follow the accounting that perpetual-motion claims leave out.
What Can an X-Ray Actually Tell You About an Ancient Object?
X-rays can reveal an object’s internal structure, joins and materials. They cannot by themselves prove its age, origin, purpose or authenticity.
Can You Really Date an Artefact to 45,000 Years Old?
A 45,000-year date can be scientifically meaningful—but only if the method, sample and chain connecting it to the artefact all survive scrutiny.
Can you smell rain before it arrives? The rain may already have landed.
Earthy petrichor begins after water hits dry ground. If you smell it before your first drop, ask where it rained upwind—and what carried the signal.
Your body does not reset every seven years. What survives the turnover?
About 330 billion cells turn over each day, mostly blood and gut. Yet old stem-cell lineages, mutations and tissue architecture can survive the replacements.
Octopuses edit their RNA. What are they actually changing?
Not their DNA and not on command. Coleoid cephalopods tune the proportion of alternate neural proteins—and cold water can move thousands of those dials.
ADHD isn’t a simple dopamine deficiency. So why do stimulants work?
The treatment is not the diagnosis. Imaging, genetics and genuine dopamine-deficiency disorders point to timing and circuits—not an empty chemical tank.
