The M87 is the largest galaxy within the Virgo cluster.
It has a diameter of approximately 120,000 light years. The Milky Way Galaxy is a mere 100,000 light years.
The Earth for comparison has a diameter of 0.0645 light seconds.
Messier 87 is an elliptical galaxy.

At the core of M87 is a supermassive black hole with about 6.4×109 times the mass of the Sun (See related question)
M87 is one of the most prominent galaxies followed by the elliptical galaxy Messier 49.
M32 - DwarfM49M59M60 (NGC 4649)M87 (NGC 4486) - SupergiantM89M105 (NGC 3379)Maffei 1, the closest giant elliptical galaxy.

Nothing. 'c' is the universal constant, the maximum velocity for all radiation in any field. Except for phenomina like the gas jet in galaxy M87 which the Hubble telescope has confirmed at significantly over 2.5 x light speed from our reference frame. This is because both the galaxy it is in and the cluster the galaxy is in are moving in the same direction.
The galaxy was actually,really,big.
No they are to big
the universe is bigger than the galaxy because our galaxy (the milky way) is in the universe.
Every galaxy contains stars, if that's what you mean. "Galaxy" means "big bunch of stars". No stars ===> no galaxy.
This galaxy, along with all the others, was created by the big bang.
