RE: What is dark matter?

in #science8 years ago (edited)

That's a nice post about dark matter. You may want to give some references from where you get this information. Not citing his/her source is not fair with respect to the author of the original place you found the information.

In particular could you please comment this part:

An experiment confirms that it has been detected dark matter in the proximities of our planet, however; some scientists think that this is wrong.

I have not heard anything about that... There is so far no hint for dark matter in any experiment. Could you please specify?

Finally, a few comments, if you allow me:

  • Why introducing 'Omega'. Introducing a symbol without defining what is the physics behind is maybe not good for communicating with the general audience :)
  • Neutrinos are considered as ordinary matter.
  • Dark matter is not only astrophysics. It is actually mainly connected to cosmology, and also related to collider physics by the way.

For more information on how we look for dark matter, you may want to check my hitchhiker guide :)

Hey thanks for your comment! I apologize because I'm fairly new to Steemit and I tend to commit some mistakes.

About the experiments I talked about, here you have a link: https://www.nasa.gov/feature/jpl/earth-might-have-hairy-dark-matter (I know I should have put some references, sorry)

About the "Omega" if you look, I linked the word to the Wikipedia, in case someone didn't know what does it mean, but I think I should have explained in the post

Well, about Neutrinos, you're right here, I have nothing to say...

And yes, you're right here too, I knew that but I should have specified or write something about that, or at least put in the tags

Again thank you for your comment, I'll try to be better in the next ones. By the way, your post looks interesting, I'll check it later :)

Hi,

You can still edit your post and modify, add and remove stuff accordingly (which would make it more accurate :) )

Concerning the experiments, this is not an experiment at all. It is actually a model proposal based on some observation. One model among many. There is no evidence for that model to be neither correct, nor wrong. Only future will tell us.

Concerning the omega stuff, the wikipedia page is after all, a wikipedia page... :) And it is very long. Maybe could you replace it by one or two lines of information (that will make the life of the reader easier).

And to conclude, do not hesitate to pass by the steemSTEM channel on the Steemit chat and say hi :)
