But some particles are being accelerated to incredible speeds, some even reaching 99.9% the speed of light. When we use powerful telescopes to look at distant objects in space, we are actually looking back in time. Such a trip would take many generations.

Calculating Light Speed

The solar system sits some 26,500 light years from the galactic centre, about halfway along a spiral arm. The solar system sits some 26,500 light years from the galactic centre, about halfway along a spiral arm. The speed of light traveling through a vacuum is exactly 299,792,458 meters (983,571,056 feet) per second. Their new concept uses a new, more durable solar sail.
