According to information , there is a "problem in data networks between South and North" that is affecting Pakistan's internet services nationwide.

 

 

Reason..

Due to fault in submarine cables, people in different parts of the country faced slow internet speed on social media platforms. The people witnessed disruption while using Facebook, WhatsApp, Instagram and other websites that was later confirmed by the authorities.

 

Average internet speeds have decreased globally as individuals have camped out to stop the coronavirus's spread. The volume of traffic is overwhelming certain Internet providers. And outdated internet hardware can become a speed impediment.

 

 

 

Affects

 

As in the start of pandemic (COVID 19) most of the people started their work from home. Slow internet access is an issue for home employee and major issue for remote workers who rely on steady internet access to work from home successfully.

 

 When you have a poor Internet connection, everyday work tasks can be disrupted. It causes delays with email communications or cloud-based telephone services, software apps, conferencing, and collaboration tools

 

Internet addiction, a lack of face-to-face interaction, time wasting, excessive use of social networking sites, and sadness are all negative effects. The report advises students to be cautious when using the internet because it is thought of as an integral component of human life.

 

 

 

 

RELATIVITY…

 

One principal subject of physics is relativity, the field of study that measures events (things that happen): where and when they happen, and by how much any two events are separated in space and time. In addition, relativity has to do with transforming such measurement reference frame that move relative to each other.

Transformation and moving reference frame were well understood and quite routine to physicists in 1905. Then albert Einstein published his special theory of relativity. The adjective special mean that the theory deals only with inertial reference frames, which are frames in which Newtons laws are valid.

(Einstein general theory of relativity treats that more challenging situation in which reference frames can undergo gravitational acceleration; the term relativity implies only inertial reference frames.)

                                                                                              

EINSTEIN DEMONSTRATION…

 

In particular, Einstein demonstrated that space and time are entangled; that is, the time between two events depends on how far apart they occurs and vice versa. Also the entanglement is different for observer who move relative to each other. One result is that time does not pass at a fixed rate, as if it were ticked off with mechanical regularity on some master grandfather clock that controls the universe. Rather, that rate is adjustable: Relative motion can change the rate at which time passes. Prior to 1905, no one but a few daydreamer would have thought that. Now, engineers and scientists take it for granted because their experience with special relativity has reshaped their common sense.

 

SPECIAL relativity has the reputation of being difficult. It is not difficult mathematically, at least not here. However, it is difficult in that we must be very careful about who measures what about an event and just how that measurement is made and it can be difficult because it can contradict routine experience.
