20–30 mins daily is enough for general health.
45–60 mins is ideal for deeper benefits.
Consistency matters more than duration.

Online teaching had become a good option but still parent reject sir to various reasons like * Internet connections are disruption * Loading of content * Time to understand the technique

Scientists are still not sure if gravity is made of tiny particles. This is an unsolved question. But the universe is already random because very small things, like atoms, behave in a random way. This comes from quantum mechanics. So even if gravity is not made of tiny parts, the universe will still be probabilistic because small particles already act randomly..

Whether gravity is quantized remains an unsolved, central problem in theoretical physics. Most physicists believe it must be, but a minority proposal suggests it remains a classical, non-quantum force. Regardless of whether gravity is quantized, the universe remains fundamentally probabilistic due to the intrinsic, established randomness of quantum mechanics in matter and energy. Here is a breakdown of the implications: If Gravity is Quantized: Spacetime itself would likely be quantized, behaving like a discrete, discrete mesh (as in Loop Quantum Gravity or String Theory) rather than a continuous, smooth surface. Gravity would behave as a quantized field, mediated by gravitons, similar to other forces. If Gravity is Not Quantized (Classical Gravity): If gravity remains "classical" (smooth, non-quantum), it would likely couple randomly to quantum matter. This approach suggests a hybrid theory where space-time curves classically, yet quantum matter remains probabilistic. Probabilistic Nature Remains: Because quantum mechanics, which governs atomic-level mechanics, is inherent in the universe's structure, the fundamental randomness (e.g., Heisenberg uncertainty) exists regardless of how gravity behaves on large or small scales
