Whether a modern student could ever gain similar powers from mathematical research alone, was still to be seen. Success, Gilman added, might lead to dangerous and unthinkable situations, for who could foretell the conditions pervading an adjacent but normally inaccessible dimension? On the other hand, the picturesque possibilities were enormous. Time could not exist in certain belts of space, and by entering and remaining in such a belt one might preserve one's life and age indefinitely; never suffering organic metabolism or deterioration except for slight amounts incurred during visits to one's own or similar planes. One might, for example, pass into a timeless dimension and emerge at some remote period of the earth's history as young as before.
