Test fire of US Navy's 32 Mejajoule rail gun prototype. Watch for the recoil at time 0:12. They do have dampeners installed, so the noticeable movement is only a few inches at most.

Recoil from a LASER weapon; a blog from a physicist at Cornell University.
http://thevirtuosi.blogspot.com/2010/04/today-id-like-to-approach-question-near.html
The summary: "...it seems like laser guns may well have recoil." (last sentence) HOWEVER, the recoil felt would be a small fraction of what we're used to.
The example he gives is that if a laser weapon were to emit the same amount of energy as there is in a fired .22 caliber bullet. In this example, the argued laser weapon would produced 15 Newtons of recoil force.

That's not entirely true actually, EVE warping is based on the theory that everything can move faster in complete vacuum ( called "perfect vacuum" ), including light. The warp drives create a bubble of a sort around the ship that clears all matter and energy particles, and then spends the rest of the capacitor power to give the ship a good speed boost. Warp drives are like slightly fancier MWDs with shiny bubbles.
The speed of light is taken for when light is in a complete vacuum. See Wikipedia.

As it's impossible to achieve perfect vacuum in practice, it would be rather difficult to measure the speed of light in it.
They don't measure the maximum speed of light, they calculate it due to quantum uncertainty (momentum and velocity can not be measured simultaneously to an infinite precision). Mind you, like all things in science, nothing is an absolute truth; a photon's calculated maximum velocity in a complete vacuum (meaning emptied of all matter) comes from the equations of today's theories.
Many technologies of today's science come purely from the results of our theories' mathematical equations.
edit: I'm talking about maximum velocity of light, here. It is completely normal to have a photon going less than the speed of light. Yes, you can measure the speed of light, but you'll always end up with something less than the calculated maximum speed.

There are still atoms of matter floating around in space. How do you think the planets and stars formed, to begin with?

Plasma is matter, not energy turd brain. lern 2 science.
Matter = energy = matter. Ever head of "E = mc^2," "energy is equal to mass times ..." ?
You can also rewrite it to a very valid m = E/c^2, where "mass equals energy divided by ..."
