 With God's help, I personally can see 100 billion light years away...is he me, or am i him?.......we are all different parts of each other........Kichimakudi (sp?), Indian web of life....


The maximum distance that we can see, which is the age of the universe (13.77 billion years) with the cosmos expanding all that time, is about 45 billion light-years away. This distance is known as the particle horizon, the cosmological horizon, or the comoving horizon, depending on how stylish you feel in the moment. That is the extent of our observable bubble, the maximum extent that we can see at this moment, today.

But wait, isn’t 45 greater than 13.77? Doesn’t that imply that the universe is expanding faster than light? Yes, yes it does.

This isn’t a big deal. That’s because the speed limit of light only applies to local observations – I’ll never see a rocket ship blast by me faster than light. If you think that’s some sort of cheat, it’s not, it’s how special relativity is constructed. Objects at the far edge of the universe can have whatever speeds they want, because they’re far away.
