You're still thinking in temporal terms, as defined by location and time. We are governed by time, and our senses are fine-tuned to note its passing, especially its linear progression. Our vocabulary for etermity and how we might percieve it, on the other hand, is not nearly so well developed. We simply don't have an eternity 'sensor' as such, but we have a sense of eternity. That may not be quite enough to describe it in a way that is easy to understand while we inhabit a physical reality. One analogy that has been suggested is that eternity is a seamless unification of the past, present and future into a continuous presence.
These are difficult concepts to comprehend. Then again, if you can contain God in a formula or explanation, then your god is too small to be God. Instead of thinking of heaven as invading your kitchen, try thinking of two overlapping universes - one spiritual, one physical. The spiritual universe is not limted to or contained by the physical universe. And as already mentioned, it is not subject to any of the laws that govern the physical universe. If it were, it most likely would have been detected by now. Hopefully, it's not an explanation for 'dark energy,' but you just never know with God.
Metaphysical speculation aside, all this largely misses the point. Things start to take a really interesting turn when the new heavens and the new earth are created after the second advent. That really will be an invasion of your kitchen, and then some. Passages like Is. 65:17- 25, 66:22-23; Rom. 8:19-21; Eph. 1:13-14 and Rev. 21:1-4 all hint of a grand unification of the eternal and spiritual with the temporal and physical.
All this is predicated on nothing less than the resurrection itself (Phil. 3:20-21). Jesus' resurrection is our assurance that our bodies 'will be like his glorious body.' That is, share the same characteristics as His body - both spiritual and physical. Any distinction between the two will thus be rendered entirely academic - a bit like my first two paras. above.
