The Greatest
Experiment, yet!

A longitudinal study in progress.

§1 · Hypothesis

Every great discovery starts with a question. Ours was simple: what if we could run the ultimate longitudinal experiment—one that would last a lifetime, demand everything we had, and change our world in a way no paper ever could?

§2 · Methods

We designed the protocol with care: a lot of research, doctors' appointments, and trust in the process. No IRB could approve this. No grant could fund it. It was just us, a hypothesis, and a due date.

§3 · Results · Week 13
Ultrasound at 13 weeks

The data started rolling in. Two lines. A heartbeat. Tiny kicks. Every scan and every flutter added another data point to the most important dataset we'll ever build. The sample size was one. The significance was infinite.

§4 · Conclusion

So here we are. The preprint is almost ready. The greatest experiment is underway—and we're ready to share one more result with the people who've been part of the journey.

We're expecting in August.
