It's a bit more complicated than that. First of all, the space-time continuum was brought out of wack by two things. The first was Ilias constantly reversing time in order to bring Luka back to life. It's said that by itself this would actually have not been a problem because the space-time continuum has the ability to repair itself to an extent.

But the big one was what happened afterwards. All that time rewinding was followed up by a much bigger event, and that was the death of Ilias herself. As you're aware, the whole world was originally made up of chaos, light and dark split from it, and Ilias is the incarnation of light itself and all that jazz. Anyway, the sudden loss of the incarnation of light itself created a huge vacuum of light energy that caused further instability with space-time that, when combined with all her time reversing shenanigans immediately prior to it, put space-time in an extremely unstable state.

This in turn caused the laws of causality itself to become unstable as well, and Ilias's death in the future had effects on her in the past as well, and this is what prevented her from stopping the experiment at Remina in some way(this part isn't explained in detail but it's probably some science causality mumbo jumbo) and thus the experiment occured and the rest is history.
