Time travel is a fun concept to think about.

When you look at the stars you look back in time. Maybe millions, billions of years. That's pretty cool, but I think it's as close as we will get
If we are looking back at time , then maybe we could travel backward in time, just not forward. The paradox issue would be non existent if when we stepped back in time a new time branch was formed. We may be able to travel backward in time, but not forward. So you are stuck in a time you chose with no possibility of returning to your home time. What you think will happen tomorrow may or may not happen the way you remember it, could deja-vu be the remnants of time travel?
No what that statement means is that light from those distant stars and galaxies take millions and even billions of years to reach us. So, essentially we are staring at their past. We cannot use this property to travel into the past.
