Steve's barking; A crude time machine has already been invented

Did you realize that a crude time machine that can take you back millions and maybe billions of years has already been invented. It's not called a time machine, but it's called a telescope.
Just think looking through one of these things you can possibly see the birth of a solar system that was born billions of years ago.
Scientists have seen the death of solar systems that happened billions of years ago.

We may not think of a telescope as a time machine but trust me it really is.
