Time travel to Earth's past would be cool to study history. But how to not accidentally ruin our timeline?
I think the real progress is to be made in space. Send a probe to a solar system 50 LY away but back in time to arrive the same day you sent it. It can travel really slow too, because time isn't a concern.
If there is a habitable planet, send settlers there at the earliest time in history possible. Settlers can be robots that just build infrastructure and plant stuff for 10k years. Then go yourself.
House was a diagnostician. His job and passion was solving the mystery. Patients have to give consent to recieve treatment.
That said, House avoided scans whenever necessary because they almost always showed benign tumors. He preferred identifing possible diseases through symtomatic analsys (discussing with whiteboard) and using diagnostic trials (trying a treatment) to eliminate remaining possibilities.
I want a series reboot.🤩
