Seventy million years ago, the earth was inhabited by giant reptiles: gigantic lizards, colossal saurains, who slithered, swam, flew. Their reign lasted one hundred million years - whereas, according to the most optimistic estimates, man has had barely six million years.

This means that these species of reptiles had in order to become adapted and to evolve, an infinitely longer time than man. Furthermore, it is impossible to pretend that they represented an evolutionary failure: any species that lasts a hundred million years must be considered to be fully adapted. Yet few species that were contemporaries of those reptiles survive -- for example, certain crabs, which have not changed in three hundred million years. In fact, in less than one million years the giant reptiles entirely disappeared.

How and Why?

We can scarcely maintain that it was because a change in climate; for even when the climate changes, the oceans hardly vary, and many of these reptiles lived in the oceans.

It is impossible to believe that a higher form of life was able to exterminate them. This would have required a considerable army, whose traces we would certainly have found.

One amusing hypothesis is that our ancestors, the mammals, might have fed on dinosaur eggs. But it is only that: an amusing hypothesis: the icthyosaurs deposited their eggs in the oceans, out of their adversaries' reach.

It has been said that the grasses changed, and that the new grasses were too tough for the big reptiles. A completely unlikely hypothesis: large numbers of vegetation types have survived, on which they could have fed perfectly well. The giant tortoises of the Galapagos Islands, the ones that interested Darwin so much, did not die of hunger.

One could say that species grow old, become senile, and die. But this is bad logic: the preservation of the genetic code prevents a species from dying out. And why haven't those species that are still living after several hundred millions of years, such as crabs and cockroaches, become senile too?

None of these hypotheses hold. But something happened. What then? An ingenious hypothesis has been outlined by two Soviet scientists, V. I. Krasovkii and I. S. Chklovski, both of whom are eminent astrophysicists -- especially the latter, who is the author of some extremely important works in astrophysics and radio astronomy. It was Chklovski, in fact, who studied synchotron radiation and showed that relatively rapid and extremely violent events can be produced at the center of galaxies as well as in space in general.

5G, and the Internet of Things (IoT) that goes with it, promises to give us more.

But more what?

Super-Fast Download Speeds 
5G and IoT promises to connect us in our homes, schools, workplaces, cities, parks and open spaces to over a trillion objects around the world. It promises cars that drive themselves, washing machines that order their own washing powder and softener plus of course super fast downloads and streaming.

According to Fortune.com 5G will support at least 100 billion devices and will be 10 to 100 times faster than current 4G technology. (4G was already about 10 times faster than 3G).

It’ll bring download speed up to 10 Gigabits per second. This would let us have an entire building of people send each other data in close to no time, thus improving productivity.

What is 5G?
5G offers mind-blowing data capabilities, practically unrestricted call volumes and near infinite data broadcast. It does this by 5G using largely untapped bandwidth of the millimeter wave (MMW), which is between 30GHz and 300GHz, as well as some lower and mid-range frequencies.

(AA) A government-funded study says radiation from mobile phones can change the way brains process sugar.

Is that a big deal? The scientists aren't sure, according to media giant CNN Health's (fake news) report. But our story has some scary tidbits.

Like this quote, from Dr. Nora Volkow, the Journal of the American Medical Association study's lead author and a neuroscientist at the National Institutes of Health:

"The human brain is sensitive to the electromagnetic radiation emitted by cell phones, but for the brain to be impacted the cell phone has to be close to the antenna. So keep your brain away from the antenna."

In layman's terms: "It's better to be safe than sorry," she says.

Despite years of research, there's still no conclusive proof cell phone radiation causes cancer and other health problems in the brain. Studies, some of them funded by the wireless industry, have produced contradictory findings. But the nearly ubiquitous devices haven't been proven 100% safe either. So, for the sake of argument, let's say you are worried about this and you do want to "keep your brain away from the antenna."

How do you actually do that?
