light speed

13.6 billion light years

I don't know - Is this a trick question.

Won't it take 13.6 light years to travel 13.6 light years?

I know a lot about space. I am kind of an expert, but I don't know what speed light goes in a second. Can you please tell me what speed light goes in a second? And space is my favorite subject.

Sorry, but what is qantum? I never heard of it.

   The speed of light in a vacuum is  186,282 miles per second ( 299,792 kilometers per second), and in theory nothing can travel faster than light. In miles per hour, light speed is, well, a lot: about 670,616,629 mph. If you could travel at the speed of light, you could go around the Earth 7.5 times in one second.

   It really is an incredibly long distance -- a lightyear is roughly 6 trillion miles or nearly 10 trillion kilometers. Here's how you calculate it. You start with the speed of light, which is about  186,000 miles per second. Then you multiply that by 3,600 seconds in an hour.

   
   

   It is really difficult.

   
   
   
   

The universe is 13.6 billion years old. This is weird.

I think that 78000000000003600000000000 is the answer. It is really difficult, and I tried. I hope it helps!
