A Unified Theory of Forces (10 of 15)

Episode 10 of In Search of Giants: Dr Brian Cox takes us on a journey through the history of particle physics. In this episode we learn why scientists are hoping that, one day, they will have a single theory that describes all the forces that govern the universe.

This film is part of a series originally broadcast on Teachers' TV (http://www.teachers.tv/video/23645).

The series was made with the support of The Science and Technology Facilities Council (www.scitech.ac.uk).

Theory of everything, yeah! I'd like to live long enough to see that day.

I love these series! So educating.

If CERN kills me I am going to be so fucking mad.

@spraitazz

The beautiful part is that it just touches what is available for us to learn.

This video is very educating while still being extremely general.

@BrightSoul80 I wonder if we'll think we have one just to find out some sort of inconsistency.

In fact, the beam of light would still travel past you at exactly the speed of light, c= 6x10^8ms-1.. Weirdly your speed makes absolutely no difference to how fast light travel from your point of view.. That's because, time for you had slowed down with reference to the source of light.. And your entire body and brain and everything that is traveling with you slows down..

[remoraid7]

In einstein's theory of special relativity he states that the speed of light will always be the same no matter how fast you are travelling.. Say you are running at 99.99999% the speed of light, and a powerful laser light beam overtakes you.. In classical physics, you should be able to see the beam of light overtake you slowly like how a 100kph car overtakes a 99.99999kph car.. However, Einstein says that this is NOT the case..

@DerangederX That sounds totally awesome! Eh, where did you get that info? (Googling 'time travel' won't get anything legit...)

[TheAlexander356]

@BrightSoul80 I'll try to see to it that that happens bud ;D

@magicyte Actually, They have created a time machine. Using lasers to push subatomic particles beyond the speed of light through a medium they can actually send bits of matter back in time. The machine has been run without introducing partials into it. Yet some appeared, because they were put into it then next day. If you actually did some research you would know this. However, since you think someone created the universe, you probably are not big on learning.

@Skindoggiedog You've heard of going forward in reverse right? It's illogical to go so fast that others around you begin to walk backwards. Would be more sensible to argue something could travel so fast that others around it would appear to slow down close to a stop...hell...even to an absolute stop for the hell of it. Anything beyond that is just rediculous. Better to leave understanding to whoever created the universe.
