Invaders from the Infinite by John W. Campbell

But it seemed, or must have seemed to any infinite being capable of watching it as it moved now, that the Thought was a mad thought. With the time control opened to the limit, and a touch of the space control, it fled across the Universe at a velocity such as no other thing was capable of.

One star -- it flashed to a disc, loomed enormous -- overpowering -- then suddenly they were flashing through it! The enormous coils fed their current into the space-coils and the time field, and the ship seemed to twist and writhe in distorted space as the gravitational field of a giant star, and a giant ship's space field fought for a fraction of time so short as to be utterly below measurement. Then the ship was gone -- and behind it a star, the center of which had suddenly been hurled into another space forever, as the counteracting, gravitational field of the outer layers was removed for a moment, and only its own enormous density affected space, writhed and collapsed upon itself, to explode into a mighty sea of flames. Planets it formed, we know, by a process such as can happen when only this man-made accident happens.
