Discussion Overview

The discussion revolves around a thought experiment involving the hypothetical scenario of transforming the sun into a linear arrangement of smaller packets. Participants explore the implications of this arrangement on gravitational strength and the challenges in calculating the resulting gravity at the end of the line.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant proposes a scenario where the sun is divided into packets the size of a house, arranged in a straight line with separations, questioning the gravity at the end of this line.
  • Another participant expresses skepticism about the question's validity, suggesting it is pointless and indicates a lack of willingness to perform calculations.
  • A third participant suggests that the relativistic effects would likely be minimal and that a Newtonian approach would be simpler for calculations, while also noting the need for clarity on how the sun maintains its stick shape.
  • One participant draws an analogy to classical electrostatics, suggesting that the mass distribution could be treated similarly to a finite line charge, and mentions that this is a common exercise in electromagnetism classes.
  • Another participant challenges the original poster's approach, arguing that they are requesting a calculation rather than engaging in a thought experiment, and emphasizes the importance of showing prior work to receive assistance.

Areas of Agreement / Disagreement

Participants express differing views on the validity and purpose of the original question, with some finding it a legitimate thought experiment and others deeming it pointless. There is no consensus on how to approach the calculations or the underlying assumptions of the scenario.

Contextual Notes

Participants note the need for specific details regarding the arrangement and stability of the sun's mass in the proposed configuration, as well as the challenges in applying general relativity to the scenario.

If i rip the sun and make it into tiny packets, a size of about a normal house and then align it in a straight line, each box having 10 cm separation, then how strong will be the gravity at the end of the line? Will it have gravity stronger than a normal sun?

How would you go about finding the answer to this? Since it is a pointless question, I'm not going to do the calculations for you.
 
I guess your answer is pointless. I asked a thought experiment. If you don't know the answer/don't want to answer, then ignore the question. My question will get answer from another forum.
 
I'd suggest asking this in a general physics forum. The relativistic effects will probably be small, and the Newtonian answer will be a lot easier to compute.

Any attempt at a GR solution would be very difficult (you'd probably be best off with some PPN approximation), and you'd need to specify the details of how the sun got held into its unnatural stick shape to even attempt an valid answer.
 
If you spread out the mass into a continuous distribution along a line, this is (classically) analogous to the electric field from a finite line charge in classical electrostatics. It's a common exercise in E&M classes, and requires only some integral calculus. A Google search will probably turn it up pretty quickly. Just change the constants by comparing Coulomb's law with Newton's law of gravitation.
 
Wanna? I don't think infantilized writing is helping you make your case.

You are not "asking a thought experiment". You are asking us to do a calculation for you. We're not "gonna" do that for you. That's not how PF operates. If you want help in doing that calculation, we will help you. Please show us how far you got on your own.
