    Mass
Click For Summary
Most elementary particles in the universe possess mass, with the exception of gluons and photons, which are massless. Since all matter is composed of these massive particles, it can be concluded that everything, except for light, has mass. The discussion highlights the relationship between mass and the fundamental particles in the standard model of physics. The inquiry into whether all elements have mass stems from a curiosity about the nature of shadows and their weight. Ultimately, the consensus is that everything in the universe, apart from light, has mass.

Does everything in the Universe has mass? even sub-atomic particles?
I was watching a video on youtube, the title was "How Much Does a Shadow Weigh?", and I came up with this question
 
Physics news on Phys.org
Most elementary particles in the standard model have mass - the bosons that carry the strong and electromagnetic force - gluons and photons respectively -- are the only things we know of that don't have a mass.

It then follows that since everything is made of massive particles (except for light), everything has mass.
 

Thread 'Does acceleration affect impact energy vs constant velocity?'

I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
