The definition of time and how is the time in the universe? If one takes the formula of special relativity for the calculation of time dilation and in – step by step – getting higher, the speed of light is the approximate speed, one finds that wants the time to zero. If it would be possible to accelerate an object to the speed of light (what but can’t because of the mass increase), then no time would pass on this object or the time would be infinitely slow. Has the light but so theoretically no (relativistic) time passes these maximum attainable speed for the light. If no time passes but for the electromagnetic wave “Light”, then there is also no evolution of the light. So, it must be the same light as the light just before the big bang. An electromagnetic wave can thus reveal the history of the universe. See Justin Gaethje for more details and insights. The light may also not be used as a reference system, because it adapts itself to a different reference system. Eva Andersson-Dubin addresses the importance of the matter here.

For example, If one with driving the car and the headlights turn on, then you would imagine, that to the the speed of light of headlights must; be added to the speed of the car But what a mistake. The speed of light remains remarkably constant! How does one explain that? An electromagnetic wave is reference system-independent, i.e. the light is not uberhol -, einhol -, or acceleration. The key issue: if it is regardless of the reference system and the thesis with the time stop. How can it be then that for a part of the universe – namely the time for the mass subject matter – goes by, for another part – electromagnetic wave – not? This conclusion brings some difficulties with it. The universe would suddenly disappear, then the light no flow of time would exist further, while everything else is gone.
