In Islamic cosmology, as described in the Quran (32:5), angels traverse distances at a remarkable speed, likened to traveling a distance equivalent to 1,000 Earth years in just a single day. This suggests an extraordinary velocity, approximately 365,000 times. According to this interpretation, the journey to the first heaven spans 500 years by heavenly reckoning, equating to 182,500,000 Earth years. By multiplying this duration by the angelic speed (365,000 times), the distance to the first heaven, from an Earth-based perspective, is approximately 66.125 trillion.

Lets try this math-
Angel travel where one day is equivalent to 1000 years, or 365,000 Earth Days.
According to Hadith, the first heaven lasts 500 Heaven Years, which equals 500 x 365 x 1000 = 182,500,000 Earth Years.
Angel speed is 182500000×365000 = 66.125 Trillion Earth Years (approx).

Note: In my view, the universe transcends what is visible to us. If we could perceive its true form, it might resemble a complex calculation, known fully only to its Creator. It’s just my calculation.
