Are angels faster than light particles (E = MC2 is non-Islamic)?

By far, Einstein's best-known equation is "**E=mc2** - *energy equals mass times the velocity of light squared*." According to this equation, any given amount of mass is equivalent to a certain amount of energy, and vice versa. In other words, **the speed of the light in vacuum is the upmost limit of the motion for anything which carries energy and or information**. But as per many incidents in Islam scriptures, we know that angels are able to travel to the heavens and back in under a 'earth day'. Angel Gabriel has also visited our planet from the **seventh heaven** many a time. It is also believed that Prophet Muhammed (SAW) traveled to the seventh heaven, visited paradise and hell, crossed the Sidrat al-Muntaha all in less than a night. Given that space is denser than vacuum and things tend to travel even slower in a denser medium, **if angels can cover such large distances in such short intervals, are they faster than light particles?** **Note** :
It takes light 100,000 light years to traverse from one corner of the milky way to the other as per current scientific knowledge. We are not aware of the orientation of the **milky way ** w.r.t to the sky of our first heaven. But given the tilt of earth's axis and assuming the sky is 'above', it would take light particles ~1000 light years to exit the galaxy at a perpendicular angle *(Avg thickness of Milky Way is 0.3kpc.)*
