That we need better theories and measurements. We cannot directly measure the mass of anything we can't put on a scale in a laboratory. What we can do is measure things like the light and other electromagnetic radiation coming at us from other objects in our direct line of sight, and apply theoretical computation and a few good guesses to get an approximation of what the mass of that object is. Taking into consideration that there are millions of objects in our milky way, and that more than half of them are not in our direct line of sight, these approximations change quite a bit when we apply different theories to what we have measured. Also, we are getting better tools to measure with, like better telescopes, detecting a wider range of electromagnetic radiation, putting some of these tools on sattelites so we get a better view, and developing more workable theories to help us explain the universe around us based on these measurements.

What measurements are needed to determine the entire mass of the Milky Way Galaxy?
The average stellar mass x the number of stars ______________________________ We can calculate the mass of the Milky Way by observing the speed at which stars orbit the center, as long as we can determine how far away they are from the center.
What does the Milky Way weigh?
What would you weigh it on? - It is more appropriate to talk about the Milky Way's mass. According to the Wikipedia, this mass is 5.8 x 1011 times the mass of our Sun.What would you weigh it on? - It is more appropriate to talk about the Milky Way's mass.

How is Andromeda and the Milky Way the same?
They are pretty similiar mass, Milky Way maybe has more mass, but the Milky Way indeed beats it in size. Milky Way is 258,000ly in diameter. Andromeda is 220,000 ly, Andromeda and the Milky Way are like twins.
How do we know the total mass of the Milky Way Galaxy that is contained within the Sun's orbital path?
Scientists estimate the total mass of the Milky Way Galaxy contained within the Sun's orbital path by measuring the orbital velocities of stars and other objects within that region. By observing how fast objects are moving, scientists can infer the distribution of mass in the galaxy. These measurements suggest that the total mass within the Sun's orbital path is about 100 billion times the mass of our Sun.
Does the sun make up 99 percent of the milky way?
The Sun makes up 99.8% the mass of the Solar System, not the Milky Way.
Is the Milky Way much smaller than the black hole?
No - The volume of the Milky Way galaxy is larger than the volume of its host black hole. The accumulated mass of the Milky Way galaxy is greater than the mass of its host black hole. The density of the Milky Way galaxy is much smaller than the density of its host black hole.
About how much of the mass of the Milky Way has yet to be discovered by scientists?
70%
What main conclusion did Shapley draw from his measurements of the distances to the globular clusters?
The sun is far from the center of the Milky Way.
Does the Milky Way universe have a vortex?
The Milky Way is not a universe; it is a galaxy.And, whatever do you mean with "vortex"? Perhaps you are referring to the gigantic black holes that appear in the center of many galaxies? In this case, yes, our Milky Way has a supermassive black hole, with a mass estimated at 4 million times the mass of our Sun.
Is a big mass of stars candy name?
plese help me
What is the Object in space contains 99.9 percent of the mass of the milky way?
It's not certain but one possibility is the super massive black hole at the centre of the Milky Way which is believed to contain as much mass as billions of Suns.
Is the milky way galaxy the biggest galaxy discovered?
No. Although the Milky Way is a relatively large galaxy it is nowhere near the largest known. Galaxies dozens of times the size and hundreds of times the mass of the Milky Way have been observed.
