take this derivation(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\hbar c = GM^2[/tex]

multiply [tex]c^4[/tex] on both sides

[tex]\hbar c^5 = GM^2c^4[/tex]

rearrange

[tex]\frac{\hbar c^5}{G} = M^2c^4[/tex]

Take the square root makes

[tex]\sqrt{\frac{\hbar c^5}{G}} = E[/tex]

Now this [tex]\sqrt{\frac{\hbar c^5}{G}}[/tex] expression inside the radical expression is fascinatingly similar to the Planck time [tex]\sqrt{\frac{\hbar G}{c^5}}[/tex]. I began to wonder if there was any physical significance between the two? Is there any?
