Hello everyone I'm fairly new to the world of Astrophysics and as such have come upon an odd question. Is there any material possible that you could assemble on earth that would have any significant Frame-Dragging or space-time distortion effects? Let's say we are able to extract, pressurize, and give a high rotation to a teaspoon of Neutronium, would it produce any noticeable distortion of space-time or have a frame-dragging effect or is this only limited to the insane conditions of black holes? And if not Neutronium, would super-dense earth metals like Osmosium combined with highly focused laser technology (Like Mallet's time machine perhaps) produce a noticeable effect? Apologies if I'm missing a very obvious point here.
