RE: A: Could dark matter be present in most massive objects, such as the Sun?
Hi, thanks for the nice article! :-)
I hope I'm not being thick here but if the universe is composed of 85% of dark matter, is it not surprising that only 0.0000000000000000000001% of the mass sun is composed of DM?
How do scientists reconciliate the huge gap between these two numbers?
Over the course of billions of years, shouldn't the sun and some DM in its path have coalesced through gravity?
The point is that the density of dark matter of the universe is not constant. There are regions depleted in dark matter (like around us) and regions with much more dark matter in it (our Milky Way has a halo of dark matter around it).
Yes, there are dark matter particles captured into the sun. That is the topic of the next article ;)
Thanks for the clarification. :-)
You are welcome!
