how much does our galaxy weigh? (the milky way)?

Question

please give the answer in multiple units

Answer 1

580,000,000,000 times as much as the Sun.
Multiplying by the mass of the sun gives:
1,153,678,(followed by 36 zeroes) kilograms.

I say mass and not weight because weight has no meaning in this context.

Answer 2

This is hard to answer, because the galaxy weighs the same as it did at the time of creation. The expansion has only moved the mass to another location. Think of a cup full of snow.. Throw it on top on a table . Now cover the top of the table with the snow. This is the galaxy as we know it. And the weight......well we would not understand the "number", as we know the world of numbers.In about 10,000,000,000 years, IT will all come back into the cup.

Answer 3

The Milky Way galaxy weighs nothing.

It, like other objects in free fall is moving in some direction according to the gravitational pulls of all objects in the cosmos. Because it is able to follow gravitational lines with no resistance it weighs nothing. Now, I know that gravity doesn't exist as Newton and Kepler thought, and it's a matter of the curvature of space, but the word gravity is much easier to type, and it is the concept of gravity or space curvature, and resistance to it that results in weight.

Answer 4

No need for multiple units. The weight of the Milky Way Galaxy is equal to:
(wUw/mwg-wUwo/mwg) Where wUw/mwg equals weight of the universe with the milky way galaxy included and where wUwo/mwg equals the weight of the universe with the milky way galaxy absent. I'm not sure, but I think Copernicus first postulated thus. Stephen Hawking ultimately prooved the equation in 1982.

Answer 5

The galaxy has no weight, it has mass.
