> Once again, E115 decays fully (multiple half-lifes, very little left) in mere seconds and is very radioactive.

That said, this only applies to the isotopes we've been able to synthesize so far. It’s not the definitive answer for all possible isotopes. Nuclear physics theories, particularly around the "island of stability," suggest there could be heavier isotopes of Element 115 with more favorable neutron-to-proton ratios. These isotopes might have significantly longer half-lives—potentially lasting seconds, minutes, or even days or weeks.

We simply haven’t discovered these isotopes yet. With better technology and experiments in the future, there’s a chance we might find longer-lived variants of Element 115, but for now, we can only speculate.

Also wondering if they resolved the main issue which is plasma disruptions in Tokamaks ? Because, you may build bigger and bigger Tokamaks but if the main issue is still there it won't change the result.

The void could also just be filled of negative-mass matter, pushing away ordinary (positive mass) matter
