    The attraction of massless particles to other massless particles and to matter

    I am really hoping someone might be able to offer a solution or at least offer guidance on something that is interesting me - are massless particles more attracted to particles with mass or other massless particles. A good example to work with could be photons: is light more attracted to...

    Missing anti matter

    I found the missing anti matter. After realizing Big bang repeats on ever larger scales with new particles forming at the knots of the large scale structure. I see galaxies flying in - these them selves behave like particles with a point particle and a wave. So it happens again, if I throw...

    Is Dark Matter Real?

    Way too many times physics amateurs have posted claiming dark matter isn't real and we should listen to them etc. I've ignored those threads because they weren't credible. However there's an article on this subject in Scientific American this month entitled Is Dark Matter Real by two...

    Where does dark matter and dark energy exist in the universe?

    Where does dark matter and dark energy exist in the universe? Moving objects will cause dark matter and dark energy to move along with it. Dark matter and dark energy are arranged to form circles around the object. These circles continuously develop a radius of a geometric progression (scale...

    Anti matter: a topic of both old and new

    In my first thread To Discuss the Gap Between Mathematics and Physics,I introduced the concept of X4 and interpreted the meaning of it. And we should recognized that the first step should be trying to find out what are the states of cosmos represented by the different X4 values. In this thread...

    Question on Matter, Energy & The Expanding Universe

    Hi - I'm an English major, not a physicist - never taken a physics class in my life, but I've been wondering about something, and hope for some help. Here it is. Is it fair to say the universe is a fixed system? By that I mean that all the matter that exists in the universe is all...

    Holding down steel plate w/ multiple magnets: Does orientation matter?

    The picture below shows an image of a bed from a 3d printer, which I intend to equip with an array of 15 x 3 mm Neodym magnets to hold down a steel plate. The steel plate itself is not and can not be equipped with magnets. Theres a heated aluminium bed between magnets and steel plate and the...

    Energy, mass and matter

    I need some sources to help me understand the relationships... matter to energy and energy to matter, what is the mechanism? For example, in my search for information I have seen it stated that a photon of great enough frequency would "decay" into an electron? Is this true? What are some good...

    Are there any electromagnetic waves that traverse solid matter, while the photos also get absorbed by electrons. Is there a slight absortion? .... by some of the photons, when they hit the electrons in the atom, as they pass through say a solid piece of matter. So with all the waves in the...

    Can EM waves like radio waves that can traverse solid matter, be combined/mixed with other EM waves to become EM waves that get absorbed by? - electrons. Also can EM waves that traverse, if certain EM waves are mixed together, say three em waves combined into a single beam, as the EM waves...

    Can any invisible EM waves that get absorbed by electrons pass through solid matter.?

    Can any invisible EM waves that get absorbed by electrons pass through solid matter.? Can any invisible EM waves that get absorbed by electrons pass through solid matter. Question 1. If you mixed any invisible EM waves, like X-rays , gamma waves, ultraviolet waves ,and micro waves with radio...

    Can you explain how light would behave as it passes through solid opaque matter in th

    -is specialized way by mixing light EM wavelengths. So you want to get solid opaque matters electrons to the same electron energy levels of glass. You use any EM, or laser light (with more intensity) to get the electrons in the solid matter to the same energy levels as glass. So for the first...

    Dark Matter a Myth ?

    Dark Matter. As I understand it Dark Matter arose from studies in cosmology in which it was observed that the many Galaxies which are revealed by our large telescopes are spinning. These seem to have a common shape in which innumerable bodies form a disc which is thickened around the spin...

    Media's influence on Dark Matter and Dark Energy candidates

    Hello. I'm currently completing a Level 3 Extended Project on the theories attempting to explain both the universe's accelerating expansion as well as the galaxy rotation problem -- both of which are extremely prevalent and highly debated topics at this time. I have created a questionnaire in...
