Is a star bigger than a universe?
no, the universe is bigger than a star. Obviously, the sun (a star) is in our solar system, which there are many stars in our galaxy, and many galaxies in our universe, there may be more that one universe contained in what I choose to call 'Infinity'.

Thanks for the feedback!
The word "universe" means "all space, all time, and everything in them". It's the concept that includes everything, and bigger than which nothing is.
No, the universe is everything in existence, meaning that nothing but the universe can exist, making it the biggest thing in the universe.
The universe is made up of space. Space as we know it is expanding into something... What that something is has not been defined. Space as we know it apparently has form and …function. The form has not yet been determined and if it will be it is at the smallest level of matter (known as the Plank Constant which is around 10 to the -35 mm) an almost inconceivably small size. Probably at this level if understood it we see what has been implied as "Space-time Foam." This "foam" contains what has been called the "Higgs Field." This "Higgs Field" is managed by the Higgs Boson which has been called the "God Particle." It is what gives mass its configuration. One big reason to build the LHC (Large Hadron Collider) in France/Switzerland is to finally spot and study the properties of this Higgs Boson. This Field determines what mass a object has. It also determines that the faster that object goes through this field the more mass it acquires, as well as the time it experiences is slowed. Not to mention that its length is shortened more and more the faster it goes. All of these transferences reach infinity at the speed of light. Consequently only photons, which are massless, can reach the speed of light without consequence. This was the important transference that Einstein describes in his Theory of Special Relativity in 1905. Therefore space itself can expand into this "nothingness," even faster then the speed of light for the Field's expansion is not restricted by the confines of the Higgs Field.
"Universe" means "all the space and time that ever was, is, and will be". So nothing is bigger than the universe. (However, a grain of sand is bigger than nothing . . . …. )
yes its bigger than the cosmos
Its not bigger its just closer. In fact our sun is pretty small and insignificant as stars go
Maybe. The biggest known star is way past the orbit of Jupiter (Source for everything-Science Channel: How The Universe Works; Extreme Stars) note: Biggest star is said to b…e a billion times bigger than our sun "Sun is nearly a million miles in diameter" 870,000miles (ibid) ...(Previous poster:Mass-wise, it's a whole different story!)
No universe is not bigger than infinity.Because infinity means point,distance at zero.
None that we know of. The Milky Way is a bit larger than the average galaxy, with somewhere between 500 billion to a trillion stars (it's difficult to know, because there are …an unknown number of small and invisibly dim red or brown dwarf stars). We don't believe it possible that any single star to be much larger than about 150 solar masses.
Of course, there's more than one life form in this universe
That's thought to be unlikely. The largest star known of so far is VY Canis Majoris, whose radius could be 2,100 times the sun's radius. If it were located in place of th…e sun, its 'surface' would be somewhere around the orbit of Saturn. Mashing together everything known today about stellar evolution, and what goes on inside stars as they grow, age, and die, it's been hypothesized that the largest possible single star is probably around 2,600 the radius of the sun. Let's make it an even 5,000 times the size of the sun, and see where that would get us: A star 5,000 times the size of the sun would fit inside the orbit of Neptune. Its surface would lie about 0.00077 of the distance to the next nearest star, and its diameter would be about 0.00000000773 the diameter of our galaxy. So you can safely say that even if astronomers are wrong about the largest possible size, and wrong by a factor of a hundred, or a thousand, or a million times, that still doesn't put it anywhere near the size of the Milky Way. They would have to be wrong by a factor of more than 3,000 times in order for the biggest possible star to reach only from the sun to the next nearest star.
No. The universe is everything that exists.
Yes. The universe is everything. It contains Earth, the moon, the planets and all of the stars. Compared to the size of the universe, Earth is not even a mote of dust.
