Questions you'd like answering, regardless of how trivial they may seem

Those little brushes for cleaning between your teeth are ok till they bend, then that's it they can't get into the gaps anymore. Why not make them out of stiff plastic (like they do with toothpicks) and not bendy wire? 🤔

There are some which are made of plastic. They don't actually last quite as long, but are cheaper so end up costing less.

Thanks for that. I use yellow and red ones, as it seems they use colours to gauge the sizes. Last week my dentist asked which colour I use. I'll try the orange ones you've linked and see if they fit in the gaps.

I was using the Yellow ones mainly before I switched to those.

The red ones are so thin, they only last a few pushes into the gaps then they bend.

How about a water-pik? I prefer them by far to anything solid - but take your dentists advice of course.

If my spaceship can accelerate at a constant 1G up to a maximum speed of not-quite-lightspeed, and can flip 180 and then deccelerate at 1G, how long will it take to reach the nearest star?

If my spaceship can accelerate at a constant 1G up to a maximum speed of not-quite-lightspeed, and can flip 180 and then deccelerate at 1G, how long will it take to reach the nearest star?

About 5.5 years.

The nearest star is 4.5 light years away. Accelerating at 1G takes almost a year to reach light speed, and will have covered about 0.5 light years while doing so.

So 2 years acceleration/deceleration, covering 1 light year, and 3.5 years of coasting in between.

For the occupants or for an observer?

The nearest star is the Sun, and you've ignored the 180 turn.

True for the first part, but not the second. Not sure why you thought I had ignored it

We don't commonly refer to the sun as 'the star'. The 180 degree rotation is obviously to allow the primary propulsion unit to be employed to brake the ship, and I think that was addressed in the answer.

Why are car boot capacities measured in litres and not cubic feet and inches? After all, litres are liquid and as far as I know you don't put liquid in a boot unless it's in a container. My guess is that litres/liquid gets everywhere, so it covers the whole space in the boot, whereas feet and inches are 'square' and won't measure the curvy bits in the boot.🤔

Litres are no more liquid than cubic feet are.

Both are just measures of volume.
