Doomsday scenarios! How the world could end...

See below a list of doomsday scenarios that could happen .... tomorrow !

1. A solar storm blasts the Earth

A ‘super solar storm’ could burn out power stations, cut water supplies, leave millions hungry, and leave satellites dead in the skies.

In 2012, solar scientist Pete Riley, said that the probability of a ‘super solar storm’ hitting Earth in the next ten years was ‘around 12%’.

Experts fear that a storm could burn out electrical grids around the world.

‘Frankly, this could be one of the most severe natural disasters that the country, and major portions of the world, could face,’ space weather consultant John Kappenman told Gizmodo.

The only account of a ‘super storm’ striking Earth comes from more than 150 years ago – when a Victorian scientist, Richard Carrington, described an eruption known as ‘the Carrington event’.

In 1859, there were no telephones and satellites, but the power of the storm devastated communications – telegraph wires around the world burnt out, and some operators reported sheets of paper catching fire.

In our wired world, the effects would be more serious – it would have been the worst natural disaster of all time, in terms of financial damage, with a cost in trillions and effects which lasted for years afterwards.

2) A supervolcano erupts. 

Could a supervolcano really plunge the Earth into darkness - and change our climate forever?

Answer: yes.
The huge ‘supervolcano’ thought to lurk under Yellowstone park will blanket the USA in ash when it finally erupts.
The eruption will be so catastrophic it will change the world’s climate.
Researchers are ‘99.9% confident’ the volcano will not erupt this century, though - and say that we will see warnings long before any eruption. Note that a super volcano erruption could be caused from a super solar flare!!!!

3) A nuclear war erupts in the Middle East

In 2015, the hands of the ‘Doomsday Clock’ - maintained by the Bulletin of the Atomic Scientists - were moved two minutes closer to midnight, due in part to the threat of nuclear weapons.

They remained there this year.

Noam Chomsky said in an interview this year, ‘The threat of a nuclear war is greater today than during the Cold War. The risk of a nuclear war is concentrated in the proliferation of incidents involving armed forces of nuclear powers.’

No state with a large nuclear arsenal - such as Russia or America - actively WANTS nuclear confrontation.’

What observers fear is a military or political confrontation which builds up tensions around a nuclear missile attack - possibly leading one side to fire.

Both Russia and NATO are still in the position to unleash global-scale nuclear attacks - and the weapons are armed and ready.

The Arms Control Association says, ‘United States and Russia still deploy more than 1,500 strategic warheads on several hundred bombers and missiles - far more than necessary to deter nuclear attack - and they are modernizing their nuclear delivery systems.

4) A man-made virus wipes out life on our planet

Astronomer Royal Martin Rees made a gloomy bet in 2003 that by 2020, one million people would have died in a single instance of ‘bio-terror - or bio-error’.

He still believes the risk of both ‘bio-terror’ and ‘bio-error’ is real.

Rees said, 'My concern is not only organized terrorist groups, but individual weirdos with the mindset of the people who now design computer viruses.’

‘My worst nightmare would be that some crazy guy with an ecology fantasy that humans were a plague would try to use some type of biological technique to kill lots of them – without caring who they were.’

In America, enthusiasts calling themselves 'biohackers’ already race to engineer new strains of bacteria - and perhaps even new forms of life.

The field of 'synthetic biology’ came into being in 2010 when a scientist added synthetic DNA to a bacteria cell to create a 'new’ life form.

An Oxford ethicist warned that it opened the door to 'the most powerful bioweapons imaginable’.

Earth LASER defence!

Astronomers have proposed to shield Earth with a barrier of powerful lasers to make it invisible to aliens and keep it safe from a hostile invasions.

A new paper published by Columbia University researchers in the Monthly Notices of the Royal Astronomical Society turns the table on our obsession with looking for aliens, and advocates defending as well as hiding our planet from the eyes of potentially belligerent space-dwellers.

In order to make this a reality, the paper suggests the use of a planet-spotting technique called a "transit method" — keeping track of a star's dips in light, which are caused by planets passing between the star and our vantage point.

This method has been used to discover over 80 percent of new exoplanets over the last 10 years, and the authors of the study think alien civilizations are probably using it to look for us, too.

In order to avoid being detected, they propose cladding Earth in the same amount of light it blocks when passing in front of the Sun. 

While there are many different ways to achieve this, such as installing sprawling mirrors, the cheapest and most effective solution is to create a shield of powerful laser lights.

The system would be composed of three different structures. One, called a "broadband cloak" which is comprised of a single 30-megawatt laser that would only be activated when Earth is in its transit phase — for about 10 hours a year.

While the first cloak would conceal us in visible light, that is not enough. We would also need a second, laser-based array employing several, smaller sources emitting high-speed light. This 250 megawatts barrier, which the astronomers nicknamed "chromatic cloak" would make sure our planet is not visible for systems employing infrared or ultraviolet detectors.

A third system, called "biocloak" would hide any sign of life on the planet (like oxygen, nitrogen, etc.) by using a polarised 160-kilowatt laser power.

What is a black hole

A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying.

Because no light can get out, people can't see black holes. They are invisible. Space telescopes with special tools can help find black holes. The special tools can see how stars that are very close to black holes act differently than other stars.

How Big Are Black Holes?

GPS nightmare

Several companies were hit by hours of system warnings after 15 GPS satellites broadcast the wrong time, according to time-monitoring company Chronos.

The company observed problems last week, after noticing some GPS time signals were 13 microseconds out.

Such a discrepancy is considered severe and several Chronos telecoms clients faced "12 hours" of system errors.

Previously, the GPS errors had also been blamed for disturbances with BBC radio broadcasts.

The perfect sun storm

On the morning of September 1, 1859, amateur astronomer Richard Carrington ascended into the private observatory attached to his country estate outside of London. After cranking open the dome’s shutter to reveal the clear blue sky, he pointed his brass telescope toward the sun and began to sketch a cluster of enormous dark spots that freckled its surface. Suddenly, Carrington spotted what he described as “two patches of intensely bright and white light” erupting from the sunspots. Five minutes later the fireballs vanished, but within hours their impact would be felt across the globe.

Astronaut in a black hole!!!

What if an astronaut falls into a black hole? Science fiction scenario but simultaneously one of the scientists thought experiment. In a theory astronaut will be able to pass the event horizon not understand something and not knowing what awaits him, but a little later the weight will start to pull towards the inside of the black hole, it stretched as "spaghetti" until eventually crashed in a singularity in the hypothetical center of the black hole at the core of infinite density.

Plasma shields

Travel in space will soon be in our daily lives, as is air travel. But there is a problem ...

Space is not empty, it is full or radiation from the Sun (Solar storms) or outside of our solar system (cosmic radiation). A spacecraft can even travel through our solar system should be protected from this type of radiation, otherwise the astronauts are at mortal risk.

Here comes a scientific team to propose a solution. Scientists from the Rutherford Appleton Laboratory built a laboratory an active shield protection from ionized particles (such as protons coming from the sun).

Plasma the forth state of matter

In our school years we have learned that matter exists in three forms: liquid, solid and gaseous. Only a few of us who have studied the subject of physics, discovered that in nature there is a fourth form of matter in which the universe is full. This fourth form of matter called "plasma". According to scientific studies, this "unknown" form of matter is 99% of the known universe. We can see this type of material in our daily lives, in fluorescent bulbs to plasma TVs, in some types of flame in games such as "plasma balls" and even the Giver of Life Sun, it is nothing other than a huge hot plasma sphere.

Unlike gases, plasma is a good conductor of electricity. Due to the electrically charged particles that make up the plasma behaves differently from a gas, for example, when applied in this electromagnetic field. So the volume and shape is determined significantly by applied electric and magnetic fields (of which usually is created).

The production of plasma by applying an electric field has important technological applications as technological processes hitherto made using non-ionized gas at high temperatures can now be made using plasma at lower temperatures. The economic benefit is obvious, and spent less energy. Also unattainable processes involving gases are technically possible using plasma
