Discussion Overview

The discussion revolves around the concept of frame-dragging and its potential effects on space-time distortion, particularly in the context of materials that could be manipulated on Earth. Participants explore whether certain dense materials, like Neutronium or Osmium, could produce noticeable frame-dragging effects or time dilation, and how these phenomena relate to the mass and density of objects, including hypothetical micro-black holes.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant questions if a teaspoon of Neutronium, if it could be created, would produce significant frame-dragging or space-time distortion effects, or if such effects are limited to extreme conditions like those found in black holes.
  • Another participant emphasizes that frame-dragging effects are determined by mass and notes that current technology cannot create a mass sufficient to detect frame-dragging effects from materials on Earth.
  • A participant references a documentary about Mallet's machine, suggesting that frame-dragging could theoretically be used to accelerate objects to near light-speed, raising questions about the conditions necessary for significant time dilation.
  • One participant clarifies that frame-dragging does not directly cause time dilation, but rather that the mass of an object influences the curvature of space-time, which in turn affects time dilation experienced by nearby objects.
  • There is a discussion about the potential for a micro-black hole to create significant time dilation effects on smaller particles within its gravitational field, attributing this to the mass and density of the black hole.

Areas of Agreement / Disagreement

Participants express differing views on the feasibility of creating materials that could produce frame-dragging effects, and there is no consensus on the specific conditions required for significant time dilation related to frame-dragging.

Contextual Notes

Participants highlight limitations in current technology and understanding of mass and density in relation to frame-dragging and time dilation, indicating that practical applications or experiments may not be possible at this time.

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.
 
Astronomy news on Phys.org
Define noticeable. Gravity Probe B just took very accurate readings of the frame dragging effect of the Earth. We've known about the frame dragging effects of the Sun for about a century now, as it was used to explain the precession of Mercury around the sun being higher than Newtonian physics allowed.

I'm not sure what your asking about in the last half of your post. Frame dragging and spacetime warping are purely determined by the mass of something. There isn't anything that we could feasibly build at this point in time massive enough to detect frame dragging from it.
 
Hmm well let me explain. This was mostly from a snippet of an idea from a documentry about Mallet's machine (which is doubtful to work IMO) where frame-dragging was used as a means of speeding an object up to near lightspeed similar to being caught on the deep event horizon of a black hole. Now I'm talking about a significant enough effect that something caught in the dragged frame can actually be time-dilated to anything more then a few seconds a year.

Mass in a general sense or in context of the object it's acting upon? Ex. Could a micro-black hole produce a time-dilation effect on a even smaller particle caught in it's EH?
 
Frame dragging does not cause time dilation to my knowledge. The mass of the larger object determines the amount of spacetime curvature which determines the amount of time dilation another object near it experiences. A micro-black hole could cause significant time dilation if a particle much smaller than the black hole was in it's gravitational field close to it. But that's just because of it's mass and density.
