Spherical galaxies do not exist in the universe.
The claim that spherical galaxies do not exist is refuted by astronomical observations and simulations, which regularly document spheroidal and elliptical galaxies.
The claim asserts that spherical galaxies do not exist. However, well-established astrophysical literature and current cosmological simulations (such as Papers [2] and [4]) frequently study and document spheroidal, elliptical, and velocity-dispersion-supported galaxies. Thus, the evidence directly refutes the claim.

Paper [2] discusses strong lensing by elliptical galaxies, which are spheroidal in shape.

Paper [4] explicitly states that cosmological simulations predict and observe spheroidal galaxies supported by stellar velocity dispersion.
