What else can I help you with?
How is the space growing faster than its keyword?
The universe is expanding at a faster rate than the speed of light.
Is the universe expanding faster than a Boeing 747 can fly?
In fact, distant parts of the Universe are moving away from us faster than the speed of light.
Is space expanding faster than the speed of light?
Yes. The farthest parts of the observable Universe are getting away from us, faster than the speed of light. The Wikipedia article on "metric expansion of space" can give you more information.
What would happen if the galaxies in the universe start expanding faster than the speed of light?
we would be all screwed
What things are beyond the universe?
Nobody Knows. Even if we travel at the speed of light we still would die before we got to the end of the universe. Everybody says the universe is expanding, but what is it expanding into?
Why is the universe estimated to be at least 156 billion light years across when it is only 13.5 billion years old?
The farthest parts of the observable Universe are getting away from us at several times the speed of light. LOCALLY, the objects (like galaxies) move at speeds below the speed of light, but in this case, it is space itself that is expanding, faster than the speed of light.
How can the universe be 156 billion years in diameter if it is only 14 billion light years old?
The diameter must be expressed in a unit of distance/length - for example in light-years - NOT in years. The answer is that the distant parts of the Universe are going away from us, faster than the speed of light. Inside its own local space, nothing can move faster than the speed of light. But in the case of the expansion of the Universe, you might say that space itself is expanding. This makes it possible for objects to move away from us faster than light.
What are the universal things?
Nobody Knows. Even if we travel at the speed of light we still would die before we got to the end of the universe. Everybody says the universe is expanding, but what is it expanding into?
How is it possible for our light horizon to be 40 billion light years away when the universe is only 13.7 billion years old?
That means that this "horizon" is receding faster than the speed of light from us. In Special Relativity, moving faster than the speed of light is not possible, but in general relativity, it is possible under certain circumstances. "Locally", nothing can move faster than the speed of light - in this case, informally, it is "space itself that is expanding".
Why is the speed of light important in physics?
The speed of light seems to be a speed limit in the Universe - it isn't possible to transport matter, energy, or information faster than that. Others think that gravity travels faster; Einstein created a universe with an infinate speed of gravity -- it's in the geometry.
Which travels faster?
The speed of light (ca. 300,000 km/second) seems to be the speed limit in the Universe. Nothing is known to travel faster than light; it seems likely that travelling faster than light is not possible.
What travel fast light or sound in the universe?
Light travels faster than sound in the universe. The speed of light in a vacuum is about 299,792 kilometers per second, whereas the speed of sound is significantly slower at about 343 meters per second in air.
