Physics, Astronomy & Cosmology / Expansion of the universe - what is being measured?
« on: 17/07/2020 09:05:00 »
I was just reading about the Atacama Cosmology Telescope in Chile. Research is as active as ever in trying to determine the age of the universe and the rate at which the universe is expanding. Does this research measure the rate at which matter is travelling through the universe or measure the actual expansion of the fabric of the universe?

Physics, Astronomy & Cosmology / Do solar neutrinos have a bypass through the curvature of space/time?
« on: 04/03/2020 08:53:28 »
Given the almost non existent size, mass and neutrality of charge of a solar neutrino, and it's subsequent lack of interaction with matter, does the neutrino travel through the universe on a straight line trajectory unaffected by the curvature of space/time?

Physics, Astronomy & Cosmology / Re: How are the results of the double slit experiment recorded?

ah thanks, now it makes sense. It's difficult to articulate questions when you're a non scientist and not conversant in scientific language.

Physics, Astronomy & Cosmology / Re: How do I explain gravity to my children?
« on: 02/07/2017 20:04:30 »
I teach in the UK. We have finished for the summer now. I am not a science teacher nor am I supposed to be teaching them science either!!! There is a cool bunch of guys that I like to chat with when they are not in lessons. I just like to throw a question out to them and then we get into a conversation about it. I'm not a scientist in any way or form but I am interested in physics and chatting things over with the guys is very rewarding. Their ideas and views are generally quite simple and always refreshing.  I always come away with a smile on my face.

Excellent replies and very useful. I work with post 16 students who have learning difficulties and the practical suggestions are very helpful.
