Re: traveling at the speed of light

If so, if we were able to travel at the speed of light couldn't we travel anywhere in the universe instantaneously (from our perspective?)

This is correct. Of course, we cannot travel at the speed of light but I suppose we could get really close, and in terms of practicality still travel anywhere we wanted in a pretty short time.
Understand the implications of this though. When you get there, the time it took to get there will still have passed.
For example, I could get in a spaceship to go to Alpha Centauri (which is a little over 4 light years from us), fly at very near the speed of light, and it would only seem like a few second trip. I could then fly home again and in total, it might seem like a day or so of exploring. Except for the fact that everyone else will have aged almost 9 years.
