ABD\u2019li bir bilim adam\u0131, fizik<\/strong> kurallar\u0131n\u0131 alt\u00fcst eden bir geli\u015fmede, laboratuvar ko\u015fullar\u0131nda \u0131\u015f\u0131k h\u0131z\u0131n\u0131n, bilinen s\u0131n\u0131r\u0131 olan saniyede 300 bin kilometreyi 300 kat<\/strong> a\u015ft\u0131\u011f\u0131n\u0131 a\u00e7\u0131klad\u0131.

Princeton NEC<\/strong> Enstit\u00fcs\u00fc\u2019n\u00fcn uzmanlar\u0131ndan Dr. Lijun Wang<\/strong>, a\u00e7\u0131klamas\u0131nda, laboratuvar deneyinin, bir \u0131\u015f\u0131k demetinin, i\u00e7inde \u00f6zel olarak haz\u0131rlanm\u0131\u015f sezyum gaz\u0131<\/strong> bulunan test ortam\u0131na g\u00f6nderilmesiyle yap\u0131ld\u0131\u011f\u0131n\u0131 s\u00f6yledi.

Wang, bir ba\u015fka deyi\u015fle, \u0131\u015f\u0131k demetinin, daha test ortam\u0131na girmeden d\u0131\u015far\u0131ya \u00e7\u0131kt\u0131\u011f\u0131n\u0131 belirtti.
\nTest sonu\u00e7lar\u0131n\u0131 inceleyen Berkeley \u00dcniversitesi fizik profes\u00f6r\u00fc Raymond Chiao, deney verilerinin \u201cinan\u0131lmaz bir duruma i\u015faret etti\u011fini<\/em><\/strong><\/span>\u201d s\u00f6yledi.

\nWang\u2019\u0131n deneyinin ge\u00e7erli kabul edilmesi halinde, fizi\u011fin temel kanunlar\u0131ndan olan ve \u201cnedensiz sonu\u00e7 olmaz veya bir olgunun sonu ba\u015f\u0131ndan sonra gelir\u201d \u015feklinde \u00f6zetlenebilecek \u201cetki-tepki yasas\u0131\u201dn\u0131n da yo\u011fun tart\u0131\u015fmalara yol a\u00e7aca\u011f\u0131na dikkat \u00e7ekiliyor. Bu durumda, bir olgunun ba\u015flamadan \u00f6nce bitmesinin m\u00fcmk\u00fcn olabilece\u011fini belirten kimi uzmanlar, bilinen zaman kavram\u0131n\u0131n \u201c\u00e7\u00f6kece\u011fini\u201d \u00f6ne s\u00fcrerken baz\u0131 uzmanlar ise \u00fcnl\u00fc fizik\u00e7inin teorisinin ge\u00e7erlili\u011fini s\u00fcrd\u00fcrece\u011fini s\u00f6yl\u00fcyor.
