The effect of collision of interstellar dust particles and photons with the spacecraft will all lead to a pressure proportional to the apparent velocity of the spaceship  $$v_s$$  <math> <msub> <mi>v</mi> <mi>s</mi> </msub> </math>  . The force exerted on the spacecraft from the curvature effect has two non-trivial components. The radial and longitudinal components scales as  $$v_s^2$$  <math> <msubsup> <mi>v</mi> <mi>s</mi> <mn>2</mn> </msubsup> </math>   and  $$v_s^4$$  <math> <msubsup> <mi>v</mi> <mi>s</mi> <mn>4</mn> </msubsup> </math>   respectively. The above obstacles become increasingly important when the spaceship travels at high superluminal speeds."
