What Gives Particles Mass? Searching for the Higgs Boson

More than two dozen UC San Diego physicists are working with hundreds of other scientists at CERN's Large Hadron Collider near Geneva, searching for a subatomic particle called the "Higgs boson." How are they doing it? What have they found thus far? And why is this search considered one of civilization's greatest quests? UC San Diego Professor of Physics Vivek Sharma, who directs the Higgs search for the CMS collaboration, explains what physicists hope to achieve at the world's largest scientific experiment, involving an estimated 10,000 individuals from 60 countries.

    this is really appreciated. i have honestly been wondering how light can have mass and thus be effected by gravity, yet travel at the speed of light and thus due to relativity travel through time very slowly. i suspect i do not explain my query well, but i am not a physicist and as i learned about relativity this particular question really vexed me. i hope as i watch the program my question is answered!

    I have a question about neutrinos supposedly gaining mass when they travel faster than the speed of light. I know very little of physics but what I do know is mass is usually decreased with speed. It seems to me that just because a particle is doing something that is opposite of what is expected...faster than speed of light, it has an opposite effect...gaining mass. So much more could be happening than gaining mass or loosing energy. Are there any theories on this? Thanks!

    and what are they going to do with this new particle when and if they find it. After that do they just pack up and go home. What other experiments will they conduct after that one is done, will they try to burst the new particle? I am not a scientist obviously so no snod remarks please i would just like a little more insight. Do they have a defined purpose or are they just searching randomly for what ever comes along. And what is the god particle? Of course there will be one of those right?

    @jeremysaint I haven't even started watching the video but.... Light has no mass. Gravity distorts space and time. The greater the mass the greater the distortion. Light is not exactly affected by gravity but the space it is on is. I don't know enough about GRelativity but at least this might help you a bit.

    There is no mass, only probability(/improbability). The 'tighter' the equation = the less probability. This we interpret as "slower" and "heavier". Gravity = improbability. Distance(/light speed) is the maximum rate of reaction/interaction of each improbability, in sequence. Entropy is the playout of infinite improbability.

    @01zaxa yes there are theories on this,its called relativity.your idea of mass "usually" decreasing as it accelerates is wrong.Its the opposite.faster somethings goes, the more massive it becomes so that as it approaches c its effective mass keeps getting larger therefore requiring more and more energy to accelerate the increasing mass to a higher speed. Eventually u get an infinite mass requiring an infinite amount of energy to accelerate, this is why we think the cosmic speed limit is c.

    Religion:100 Science:100 The bible says heaven is a spiritual place or an alternate universe of which we cannot see or touch. As professor Sharma states the CERN (LHC) collider in Geneva may answer other scientific questions such as 'Are there warped extra-dimensions of space' (7:50). If we find these extra-dimensions does that prove there is a heaven? No, but we can hope it does; a very smart man once said "imagination is better than knowledge". Who was that smart man?

    @jeremysaint Light has no mass. The particles that light is made up of are called photons and they are massless particles. Massless particles only travel at the speed of light. They are affected by gravity because according to Einstein, gravity is simply warps and curves in the geometry of space-time, and these warps and curves affect the propagation of light and anything that passes through.

    +Bo McGillacutty Maybe the higgs particle has no mass but its interaction with other particles causes those particles to have mass as a bi product. We have spent so long looking at the universe in a mechanistic (is that even a word?) manner thanks largely to Newton its now difficult to shift up into a quantum veiw of everything. I maybe wrong but 99.999% of an atom is empty space , the electromagnetic force of the atom is what fuels the illusion of being "solid mass". I'm totally digging simulation theory at the moment, maybe our universe is just a simulation on some quantum computers from the future. The maths is really starting to look that way but what do I know im just a chef :)

    Nick Butcher Yes that is a real word. Apparently the LHC has discovered the Higgs *and* narrowed down it's mass value....but like most here I'm only repeating what I've been informed of not grasping the significance entirely. I sort of dodge the whole simulation hypothesis as interesting but not usefully informative or conceivably determinable....I choose to let others toy with that one as I just don't see how it will change my approach to life on Earth regardless....it and we are still exactly what we are anyway.

Particles that change there behavour when observed this for me is what nails it for simulation theory, that and everything coming from nothing 13 billion years ago (like when you turn on your p.c) Knowing were in a simulation shouldn't detract from life. It should improve it. Who knows what were truly capable of :)
