I remember reading that shortly after the big bang (you know, something like a minute after it) the universe was many light years across. This tells me that the universe expanded faster than the speed of light... But I thought nothing can travel faster than c... What exactly am I missing here?

EDIT: Uh, this is my first time on this site, how can I reply to the answers given? To parvaz: I thought whole point of special relativity was that light is always c REGARDLESS of source and reference frame?!?!

Inflation, which only lasted for less than a trillionth of a second after creation, solved a lot of math problems with the Big Bang scenario. During that period space expanded more percentage wise than in the 14 billion years since then. The laws of physics were so strange then that none of the rules we know of now worked the same.
It's a common misconception, put out by science editors who only know how to act smart, that the universe was light years across whn inflation ended. It was actually about the size of a proton. The universe expanded at an incredible rate then, but only for about 10 -35 seconds. (1 over '1 followed by 35 zeros' "

a million) What Relativity truly states is that 2 gadgets passing one yet another won't be able to have a relative p.c. more suitable than the speed of sunshine. 2) if in case you've the false impression that the increasing universe skill some merchandise is getting larger, like blowing up a balloon yet truly its unlike that. extra room is generated contained in the present universe. this signifies that each and every merchandise (on the large scale) in simple terms unearths that each and every different merchandise is extra faraway from it. No particular merchandise strikes everywhere in the sense of travelling in a direction, the recent area in simple terms signifies that each and every thing receives extra aside. This 'enlargement' via new area being generated isn't some thing to do with accelerating or maybe shifting gadgets in the ordinary sense and so distant gadgets do locate that the area between them can strengthen at more suitable than the speed of sunshine. in the intervening time, regionally shifting gadgets are nevertheless constrained to the speed of sunshine.

dear first i dont suppose that u read any time limit like 1 min or so.the so called small time interval fr univrse can actually be very big on ordinary scale of time.fr ex 1 million years fr universe is like one or two sec in yr life.scientists hav found some galaxies which are travelling almost at speed of light which led to speculation that initial big bang could be very fast.but mind u it is still a theory and there is no confirmatory proof to it.(although it answers many other ques abt universe that is why this theory exist)
and fr yr information scientists are working on possibility that particles can even run with speed greater than c.it is proposed by an indian scientist.but in that world you hav to die before u born.they are called tychons(pardon me if spelling is wrong) .and we cant interact with particles(or possibly with creatures) of that world

the thing u r missing is that the speed of light depends upon its source.the speed of light from sun far less in speed as compared to a speed of light of super nova.hence something can travel faster than the speed of light depending on its source.

in bigbang the energy released was way to great thereby it was possible that the universe expanded faster than the speed of light...:))
