Compressing super-fluid Helium?


Hello,

I had an idea recently about compressing helium to unimaginably small sizes. Since resistance to compression is caused by individual atoms colliding with the container, and super-fluid helium has almost no atomic movement, couldn't you compress the helium to incredibly small sizes? It's just a random idea, but it may work.

How stupid of me, you can't compress a liquid. Sorry.:D

Actually, it's the Pauli exclusion principle. All those 1s electrons don't want to be overlapping each other.

Of course you can.
If you want to learn about superfluids, you should first learn about regular fluids and leave elementary school myths behind. :)

Fluids are compressible. I think I've read somewhere that if water wasn't compressible, the sea level would be some 20 meters higher above the Mariana trench.
