A thought experiment is presented in which it has been proven that on the basis of the trajectory of a laser pulse in a moving frame of reference (spaceship) with a constant velocity, it is possible to determine the direction of movement and speed of the system with respect to the velocity of light. It has also been shown how this statement could be experimentally confirmed. We conclude that Einstein&amp;#039;s&amp;amp;nbsp;&amp;lt;/span&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;/em&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;em&amp;gt;principle of relativity&amp;lt;span style=&amp;quot;text-transform: none; background-color: rgb(255, 255, 255); text-indent: 0px; letter-spacing: normal; font-style: normal; font-variant: normal; font-weight: normal; font-size: 12px; line-height: normal; font-family: &amp;#039;Helvetica Neu&amp;#039;, Helvetica, &amp;#039;Lucida Grande&amp;#039;, &amp;#039;Lucida Sans&amp;#039;, &amp;#039;Trebuchet MS&amp;#039;, Arial, Helvetica, sans-serif; white-space: normal; float: none; color: rgb(0, 0, 0); word-spacing: 0px; -webkit-text-stroke-width: 0px; display: inline !important;&amp;quot;&amp;gt;&amp;lt;span class=&amp;quot;Apple-converted-space&amp;quot;&amp;gt;&amp;amp;nbsp;&amp;lt;/span&amp;gt;needs a revision.&amp;quot; &amp;amp;nbsp;( Paper&amp;#039;s English language version:&amp;amp;nbsp;&amp;lt;/span&amp;gt;&amp;lt;/em&amp;gt;&amp;lt;span style=&amp;quot;font-family: &amp;#039;Helvetica Neu&amp;#039;, Helvetica, &amp;#039;Lucida Grande&amp;#039;, &amp;#039;Lucida Sans&amp;#039;, &amp;#039;Trebuchet MS&amp;#039;, Arial, Helvetica, sans-serif;&amp;quot;&amp;gt;[http://www.zbigniew-modrzejewski.webs.com/PE01051209EPep.docx www.zbigniew-modrzejewski.webs.com/PE01051209EPep.docx]&amp;amp;nbsp;)&amp;lt;/span&amp;gt;[[Category:Scientific Paper]]&lt;br /&gt;
