Massive Solar Storms May Shutdown Internet Around The World, Fears Expert

Dated:-31 Aug 2021

Solar storms or coronal mass ejections are known to cause damage to electrical grids and cause blackouts, however, experts are of the belief that they could also adversely affect the internet infrastructure, causing a global internet outage. 

This was revealed by the University of California, Irvine’s Sangeetha Abdu Jyothi at the SIGCOMM 2021 data communication conference last week. She revealed, in her research, that even though local and regional internet infrastructure would be at low risk of damage during extreme solar storms as they mostly use fibre optic cables and are not affected by geomagnetically induced currents. Even short cable spans that are susceptible to these storms are grounded regularly, eliminating the possibility of damage. 

However, the same cannot be said for undersea cables that connect continents together. Even though most of these continents are connected via fibre optic cables, the repeaters that amplify the current at regular intervals are highly susceptible to failure, and if most of these repeaters on a network go offline, it could be enough to create an internet blackout in a particular nation that only relies on the internet coming from undersea cables.

The most recent solar storm that occurred in 1989 took down a Hydro-Quebec power grid causing a nine-hour power blackout in northeast Canada. And after seeing decades-long low-solar-storm activity, experts fear that we could soon be on the verge of experiencing another massive solar storm.

What is the smallest possible Distance in The Universe?

In physics, the Planck length, denoted ℓP, is a unit of length that is the distance light travels in one unit of Planck time. It is also the reduced Compton wavelength of a particle with Planck mass. It is equal to 5.72938×10⁻³⁵ m (Lorentz–Heaviside version) or 1.61623×10⁻³⁵ m (Gaussian version). It is a base unit in the system of Planck units, developed by physicist Max Planck. The Planck length can be defined from three fundamental physical constants: the speed of light in a vacuum, the Planck constant, and the gravitational constant. It is the smallest distance about which current, experimentally corroborated, models of physics can make meaningful statements. At such small distances, the conventional laws of macro-physics no longer apply, and even relativistic physics requires special treatment. The smallest possible size for anything in the universe is the Planck Length, which is 1.6 x10 -35 m across. It is impossible to determine the difference between two locations less than one ...

How do Ants sense Food?

  S ugar has a slight odor, particularly granulated beet sugar. While all species of ants can differentiate between a wide variety of odors, the smelling range differs from a few centimeters to meters. Desert ants can smell sugar from up to 3 meters. the food sources that ants cannot smell from a distance they 'smell' it (contact chemoreception) by touching it. So in a way, all the food they detect, they detect it by smelling. So yes, ants smell (although contact chemoreception is more like taste) the sugar. The ant colonies send scout ants to search for food in various directions, often up to a range of 100 to 200 meters.(Depends on the territorial boundary and time of the year). The scout marches steadily in less circuitous paths initially if it has memories of previous feeder locations. (Ants use visual landmarks, and a stereo-smell system to create an odor map and navigate) Periodically it will halt and look for olfactory cues. It will then take into a more circuitous rando...

WATCH INSTAGRAM STORIES ANONYMOUSLY!!!?

 If you want to see anyone's Instagram story without letting them know, If you've ever wanted to be a fly on the wall at an Instagram Story, then this blog post is for you.  In this post, I'll tell you all about the best websites that will let you watch anyone's stories anonymously. In addition to that, you will not need to login into that website. Ahead of time, though, there are a few things that everyone should know before trying to spy on someone else's Instagram Stories. You need to have a bit of patience in order to make this work, given that there's always a chance that the one you're spying on could beat you to it. Most importantly, you can't expect this to work for every account that you try it on. There's also no way of knowing how much of the stories you'll actually be able to see and how long the access will last for. However, you cannot be able to see the stories of those who have a private account. below are the links to some websit...
