I have seen roger Penrose video https://www.youtube.com/watch?v=sM47acQ7pEQ. In it explains that time origins are related to the rise of mass in the early universe. In the video it relates mass from Enstein E=MC^2 to planks equation E= HF (F stands for frequency). As there was no mass in the very early universe time did not exist. So time is a consequence of the rise of energy=MASS=Frequency.
However although particles would have no mass at rest their (kinetic) momentum must have provided mass (as it happens to the photon) in the very hot early universe (prior to the highs effect) thus time must have existed as well prior and must have risen with the development of zero mass at rest particles having momentum.
When looking at very short lived particles or virtual particles as per quantum mechanical uncertainty, any object or process that exists for a limited time or in a limited volume cannot have a precisely defined energy or momentum. So a certain volume of space is necesary for particles to become real via their momentum, prior to this, time does not exist as there is no certainty about momentum or energy within the smaller than required space (smaller than that of the wavelenght of the particle).
Could you please let me know if the reasoning is correct
