 We commonly speak of things being impossible in a relative sense. If you are stuck in a traffic jam in Paris Montparnasse at 2 PM, and your flight is leaving from airport Charles De Gaulle at 2:30 PM, you may moan: “There is no way that I can make it to the airport in time”. What you mean is that, given the timing, the means of transport available, and other circumstances, it is impossible for you to reach the airport in time. It is not absolutely impossible: if you had Star Trek’s transporter, you could make it.
