Moving to the very large, gravity should be slowing the expansion of the universe, yet we observe that it is not. Something is pushing the galaxies apart. Dark energy is the term originally given to whatever force that is. One possibility is that where ordinary matter attracts other ordinary matter (gravity), ordinary matter repels dark matter (antigravity). Or perhaps the dark matter increases the mass of the universe, and so the total energy of the big bang, to the point where it simply hasn't had time to stop expanding yet. Who knows?
This is one of the most short-sighted comments I've ever seen - and they abound on the internet. Your statements belie you assertion that you are a scientist. The computer and network that allowed you to post your comments were made possible by the work of physicists whose work was purely theoretical when it was new; but it was elaborated on and tinkered with and then applied by engineers to make the electronic world we live in.
You know I thought the neutron was simply a proton and electron fused together. From a mass and charge point of view that is true.
Yet the video didn't draw the neutron that way, instead using a combination of those u and d things.
The problem with this video is that it doesn't really tell me what the Higgs boson is. If it is a particle that gives other particles mass, that means every particle that has mass must be made up of Higgs bosons. But how?
The Higgs boson represents the culmination of the physicists' biggest welfare project to date. It keeps them employed and they can but billions of dollars worth of equipment and instruments, which makes the suppliers happy. As far as I can tell, neither the Higgs boson nor knowledge about how the universe started with the Big Bang have any importance to daily life. So it's discovery is a non event with no significance except to the Nobel Prize committee; and what do they know? Years ago the Nobel prize in medicine went to the doctor who devised the frontal lobotomy. And more recently the Nobel Peace prize went to Yasser Arafat. Take it from a scientist, the Higgs boson means nothing.
Correct, although how well supported and how widely supported differ from one theory to another. I would also add that any scientific theory must be falsifiable. Until someone can prove it is false, a scientific theory remains valid (as it is supported by observation and experiment)
I am always shocked when I hear the word "just" lumped with "theory". And on a technical website yet! A theory in the science and technical world is a set of well tested, and widely accepted explanations for known facts.
Perhaps too, I don't think there is much that is more important to the human race than discovery. It is "eating the apple" that makes us unique, after all. As far as I'm concerned, there are not many more worthy causes to sink some money into.
