Schwarzschild Metric - Rindler coordinates

Click For Summary
SUMMARY

The discussion centers on the Schwarzschild Metric and its transformation into Rindler coordinates, specifically addressing a calculation error encountered by a user while interpreting equations from the paper "Quantum Black Holes" by Atish Dabholkar and Ashoke Sen. The user attempted to derive the relationship d\xi^{2}\frac{2GM}{\xi}=d\rho^{2} but found discrepancies in their calculations. The correct derivation involves the equations ρ2 = 8GM ξ and dρ = √2GM dξ/√ξ, leading to the conclusion that careful attention to mathematical transformations is crucial in theoretical physics.

Hello, well I just read a paper by Atish Dabholkar and Ashoke Sen, titled "Quantum Black Holes", pp. 4-5 as shown below

and I tried to find d\xi^{2}\frac{2GM}{\xi}=d\rho^{2} like this

which is different from the eq. in the paper.

So, could somebody please help me to find my mistake in the calculation? Thank you
 
Physics news on Phys.org
ρ2 = 8GM ξ
ρ = √8GM √ξ
dρ = √8GM ½dξ/√ξ = √2GM dξ/√ξ
2 = 2GM dξ2
 
Ah thank you so much :D
