Sets are called the building block of maths, but why? To me sets are a collection of 'things'. Were as numbers are what give the 'things' a meaning. Myself I think that addition is the building block and maybe subtraction, all the other processes, addition and division are only quick ways of...

In a lesson on square roots this came up (Root) 27 simplifies too 3(root)3 ok. when I work that out it's = 5.196... or if I say 3squard (root)3 this works out to 15.588.... What am I missing?

while the photon travels at light speed and a neutrino travel at just below light speed why then are photons stopped by an object and the neutrino can past through?

As the universe expands all objects are moving away from us, so how is it posible that the Andromeda galaxy is on a path to merge with our galaxy?

This a quote from Nature of the 30 of june 2022 'Like the electron, the muon has a magnetic field that makes it act like a tiny bar magnet. As muons travel, they generate various particles that briefly pop in and out of existence." Now I would like to know how 'various particles' pop in and out...

When something is described as say 7 billion light years away would't it be more accurate to 7 billoin years ago?

It seem incredulous to me that the Milky Way was formed just 13.775 million years after the start of the universe. If this is correct was it in the form that it is today?

Light is red shifted further into the red as the object recedes from our viewpoint. So when the object gets so far away that the red shift goes into the infer-red it then disappears from our view at the same time it will be going at a very large percentage of light speed (99.999...%). So light...

PIxinsight: in Star alignment go to Star Detection and try these settings:- Detection scales try 8 Log Sensitivity try -3 All the rest in star detection leave at default

you can still get it on DVD!

Thank you all for explaining

So I was right in my thoughts that for a given mass regardless of it's compaction the gravity is the same. This brings up another query: Why is it only black holes colliding that is produce gravity waves that are detected? Is it because the said B/H have such a high density?

I've just watched a vid about jets of matter and neutron stars. It was stated in it that a neutron star is a star that's been compressed from say a sun sized star to the size of a city, every thing OK upto now. Then it goes on to say that it has, the neutron star, enormous gravity, this is were...

No not a mass. Was just reading that they may have been found by the Liquid Scintillator Neutrino Detector and it seemed that if they are so hard to detect here on Earth then they may be a candidate for Dark Matter.

I would like to hear what the opinions are. Could sterile neutrino's be dark matter? I'm sure this has been discussed if not here then somewhere.
