A reliable source says the earth and the physical universe will be destroyed and recreated before then.
Isaiah 65:17
New International Version
“See, I will create new heavens and a new earth. The former things will not be remembered, nor will they come to mind.
Revelation 21:1
New International Version
“Then I saw “a new heaven and a new earth,” for the first heaven and the first earth had passed away, and there was no longer any sea.”
I think what was said about the earth & the physical universe was about right, but not so sure as to WHEN it will happen. God alone knows that time period.
