No, every point in an open space does not contain the image of the observable universe. The observable universe refers to the portion of the universe that we can currently see or detect from our vantage point on Earth. It is limited by the distance that light has had time to travel since the Big Bang, which is currently estimated to be about 93 billion light-years in diameter.
Even if you were between galaxies and had a complete spherical view with the ability to detect the entire electromagnetic spectrum, you would still have a limited field of view. While you may be able to observe a significant portion of the universe, your view would not encompass the entire observable universe.
Additionally, the universe is constantly expanding, and the light from distant objects becomes more and more redshifted as they move away from us. Beyond a certain distance, the expansion of the universe causes the light to be redshifted to such an extent that it falls outside the detectable range of our instruments, making those regions effectively invisible to us.
Therefore, while you might have a vast and impressive view, it would not encompass the entirety of the observable universe due to the limitations of distance and the expansion of the universe.
