In the illustration above, every single point of light you see is a galaxy. You are inside a hypothetical ship which can navigate across the universe at an astonishing speed of around 630 trillion times the speed of light! (Which is, by the way, an impossible speed to attain.) This means it covers 20 million light-years in one second; approximately 100 galaxies are flying past you every second.

​

At this speed and rate, if you wanted to visualize all two trillion galaxies in the observable universe—effectively surveying all the galactic clusters of the entire observable universe—it would take you about 634 years to pass them all. This means if you stared at this page for 634 years, only then would you have a chance of actually completing a "flyby" of every galaxy we know in the observable universe. It is also worth noting that the actual size of the universe could be much larger than current known limits—it is likely infinite.

​

Imagine what could be possible in all those galaxies?

​

IAn important thing to remember is that our hypothetical ship does not travel diametrically or radially across the volume of the universe; it covers the entire volume of the universe. If you were to travel diametrically at this hypothetical speed, you could cross the entire universe in just 77 minutes!
