Do you fear the bubble of true vacuum?

Is there nothing we can do escape it? Create another universe ourselves before it happens and "jump in" perhaps?

is it necessary

Well, what if it's real? It might not be. But then what if it is? The universe has to end somehow.

Wouldn't it be great if we could stop that from happening?

We are programmed to survive. The knowledge that all of our work will be erased one day (by the collapse of the false vacuum or by some other unavoidable cataclysmic event in the very distant future) creates absurdist existential angst in all of us.

The goal of human existence should be to at least TRY to overcome these events, and to extend the existence of life for as long as possible, if not for an eternity. But we won'y try unless we maintain the hope that this might be possible. Maybe many millennia from now, but possible.

Estimates indicate that happen within billions of years, worry that happen in your life? No.

Estimates indicate it could happen any time between several billion years in the future ... and _now_

Nuclear physicist here. What you're referring to is a vacuum metastability event, and no, you should not be afraid of it. Estimates of the stability of the universe's vacuum are made with the mass of the Higgs Boson and I believe the top quark, and most theoretical predictions say that even if it were to happen, it would be billions of years from now. Basically, when you deal with tunneling phenomena with some kind of potential barrier you have a certain "knocking frequency," which is basically how many times per unit time the system oscillates between the two sides of the barrier. For things like atoms, this frequency is rather fast, which leads to things like alpha decay. But when you scale this up to a system the size of the universe, that knocking frequency becomes immensely slow, to the point where it would take, like I said, billions and billions of year for there to be a possible tunneling event.

TL;DR Hawking and company aren't worried about it, so neither should you be.

True vacuum exists everywhere in between atoms and fundamental particles

Thanks for that. All I'm saying is that, if not now, I think we should hope to worry about it at some point.

As one teacher told me long ago: If you're worried about what happens in a billions years, then follow worried.
