## The Hubble Time
The Hubble time is the reciprocal of the Hubble constant, giving the time scale of the present expansion.
### Formula
**t_H = 1 / H0**
To convert, note that 1 km/s/Mpc = 1 / (3.086 x 10¹⁹ s).
The Hubble radius c / H0 defines the distance at which the recession velocity equals the speed of light.

हल किया गया उदाहरण
H0 = 70 km/s/Mpc.
- t_H = 3.086e19 / H0
- t_H = 3.086e19 / 70 = 4.409e17 s
- In Gyr: 4.409e17 / 3.156e16 = 13.97 Gyr
- Hubble radius = c / H0 = 299800 / 70 ≈ 4283 Mpc
