Thanks for posting, it's in our genes to continue to push the speed record, and explore. I think both go hand in hand.

Micro particles could possibly be dealt with using some arrangement of electrostatic fields, the larger grains with lasers, and the even larger objects by avoidance.

In pursuit of speed and journey, we often find solutions to problems along the way.

And while we may not be able to exceed the speed of light, I personally have found no reason we can't out run it.

According to Special Relativity, mass increases as you approach speed of light, and would be infinite mass at that speed.

There's your reason right there. Matter cannot travel at SOL.
