Here is what we have about Jesus and creation >
"He is the image of the invisible God, the firstborn over all creation. For by Him all things were created that are in heaven and that are on earth, visible and invisible, whether thrones or dominions or principalities or powers. All things were created through Him and for Him. And He is before all things, and in Him all things consist. And He is the head of the body, the church, who is the beginning, the firstborn from the dead, that in all things He may have the preeminence." (Colossians 1:15-18)
So, Jesus is
"the image of God" and everything was created
"for Him". And we have this >
"For whom He foreknew, He also predestined to be conformed to the image of His Son, that He might be the firstborn among many brethren." (Romans 8:29)
So, Jesus is
"the image of God" > all who God is, perfectly wonderful in love and all that is good and right. And our Father is so pleased with His Son, that He has destined His children to be conformed to the image of Jesus, so we also are pleasing to our Father like Jesus is.
And all creation was made
"for Him" . . . including for God's purpose to produce many children who are like Jesus. This earth, first of all, is His place for producing people who become conformed to the image of Jesus.
So, in answer to your question . . . in case I have understood you correctly > this earth will last as long as God uses it for this personal purpose. All is personal, not only about physical laws and what they might cause. And then . . . according to what I read in Romans 8:21 > the whole earth will be resurrected so it is suitable for resurrected people who are like Jesus >
"because the creation itself also will be delivered from the bondage of corruption into the glorious liberty of the children of God." (Romans 8:21)
So, God's creation . . . the way it is now . . . will not last only the way that physical laws of energy decide, but until God has accomplished His purpose of this creation for Jesus.
And this purpose is so Jesus has
"many brethren". So, the purpose of this earth is personal and about family
