Lost in Space: Half of All Stars Are Rogues Between Galaxies

[Baclava]

As many as half of all stars in the universe lie in the vast gulfs of space between galaxies, an unexpected discovery made in a new study using NASA rockets.

These stars could help solve mysteries regarding missing light and particles that theory had suggested should exist, scientists say.



This concept shows a number of galaxies sitting in huge halos of stars. The stars are too distant to be seen individually and instead are seen as a diffuse glow, colored yellow in this illustration.

---------------------------

Wouldn't that account for missing mass too?

"Dark matter" is just quintillions of dim rogue stars and planets circling every galaxy like a cloud


..if any universities are listening - I would be willing to expand on my grand theory for a small grant fee of $12.5M to start - yes - I take Paypal

1. If I was a Star, I would be a "Rogue Star". Yes, I would!

Surprised that there are that many of us!

[Baclava]

2. i'd be an asteroid pilot, power them up and head into deep space

rock is great insulation from radiation, a home away from home...rig up a solar sail or some other power source and spread our seed to the stars






It is our destiny

4. They won't know what hit them. An entirely new branch of astrophysics will need to be created.

Just to study the awesome of it all!

11. Why thank you, us visionaries are so rarely appreciated in our time

lasso some rock roids and get them moving to the outer rim of the solar system!



earth orbit is so boring....any monkey could do it

but first we have to prove we can survive deep space - no need to build ships - use natural materials to get started

6. I want to be a rouge star.

That misspelling just kills me everytime I see it, and I see it Often.

3. Keeping their distance yet can't break free of galaxy gravity

The truly rogue ones get a big enough toss to become real loners.

5. Imagine what the sky would look like...

... if you lived on a planet orbiting one of the more roguish stars.

7. I think the missing mass has to be inside the galaxies

Much of the evidence for dark matter comes from the study of the motions of galaxies.[22] Many of these appear to be fairly uniform, so by the virial theorem, the total kinetic energy should be half the total gravitational binding energy of the galaxies. Observationally, however, the total kinetic energy is found to be much greater: in particular, assuming the gravitational mass is due to only the visible matter of the galaxy, stars far from the center of galaxies have much higher velocities than predicted by the virial theorem. Galactic rotation curves, which illustrate the velocity of rotation versus the distance from the galactic center, show the well known phenomenology of the Universal Rotation Curve that cannot be explained by only the visible matter. Assuming that the visible material makes up only a small part of the cluster is the most straightforward way of accounting for this. Galaxies show signs of being composed largely of a roughly spherically symmetric, centrally concentrated halo of dark matter with the visible matter concentrated in a disc at the center. Low surface brightness dwarf galaxies are important sources of information for studying dark matter, as they have an uncommonly low ratio of visible matter to dark matter, and have few bright stars at the center which would otherwise impair observations of the rotation curve of outlying stars.

To get the pull of gravity on an object towards the center of a system greater, you have to put more mass closer to the center than the object. The overall gravitational effect of a spherical shell of matter at a greater radius is zero.

8. At half the stars, there simply isn't enough mass to account for all dark matter.

The estimate is that dark matter accounts for over 80% of the matter in the universe, and the stars in galaxies, less than 20%.

9. Sarah Palin considers herself a rogue star.

She belongs in outer space.

[malaise]

12. Are you sure she isn't a star

rogue???

13. This is mind bending stuff. scifi stuff

In the last few years science has inferred that free will does not exist and we are controlled by microbes.

And stars fly around ignored...crimony.

I should start smoking pot.
