Not surprising, you're both wrong as has been demonstrated.
And there is no center of the universe. Galaxies are all moving away from each other (Hubble expansion) so wherever you are is the center of the universe, everything is moving away from that point. So if everywhere is the center there can be no center.
Ever blow soap bubbles as a kid? Imagine a bug can be on the bubble without breaking the bubble. As the bug runs along the bubble as you're blowing the bubble bigger when does he reach an edge? No matter how fast he runs.
You are going against observed astronomy. Ever hear of the Sloan research and Hubble's concentric spheres of galaxies? It's called quantized red shifts. Hubble said he didn't like it because it appeared display design. There are distinct groupings of galaxies in spheres around the Milky Way approximately 2,000,000 light yeas apart. With the Milky Way at the center we are like a pea inside a marble inside a ping pong ball inside a golf ball, etc, etc for 13 billion light years of spheres of galaxies. If the Milky Way was off center by even 0.0153% the spheres would blur together and we would not be able to see what Hubble discovered in the 1920's; and was verified in the 1970's and again in the 1990's. That is real science.
In 2002, Hawkins et al. found no evidence for redshift quantization in a sample of 1647 galaxy-quasar pairs from the 2dF Galaxy Redshift Survey:
"Given that there are almost eight times as many data points in this sample as in the previous analysis by Burbidge & Napier (2001), we must conclude that the previous detection of a periodic signal arose from the combination of noise and the effects of the window function."[28]
You didn't use logic or reason to get into this opinion, I cannot use logic or reason to get you out of it.
