How can we look back in time by viewing distant objects in

Resolved Question:

How can we look back in time by viewing distant objects in the universe if time started at the big bang and travelled out with the expansion? Where we are now took millions of years to develop into so time has travelled out with us up to now. If the space we see is like the surface of an inflating balloon (?) then what we see in the far distance isn't 'back in time' just 'in the distance'...?

Hello, welcome to Just Answer. Like you said, it's not back in time but just at a distance. When we see something we don't have direct sight of it, the information is transported by light (photon). Light don't travel at infinite speed, this mean that the light coming from a far object in space is a snapshot of some proprieties of the object at that time but while the information travel to us, the object in question continue to change.
