Due to the car while driving in the acceleration is difficult to explain, recently Toyota recalled millions of cars Toyota. This is obviously a breakdown of the deadly consequences, according to statistics may have led to more than 100 people were killed.

Toyota has been busy looking for the cause of the problem, and repair machinery fault (for example, the brake pedal), but they really find the right direction?

Although it sounds a bit like the truth “function to peel”, but the federal regulators are investigating whether these “accelerated” suddenly from high-energy particles of the universe.

Mars attacks

As is known to all, cosmic rays would bombardment of the earth’s atmosphere, still can destroy the sensitive electronic devices in space.

Many space probe had threatened by cosmic – for example, NASA’s Mars reconnaissance rail vehicle (MRO) — often forced them to switch on the star computer security model, thereby protecting themselves from further damage.

For from solar flare MRO or deep space supernova energetic protons are considered the cause of failure in recent time.

But in close vacuum MRO space, the atmosphere under the protection of the car will be why energetic protons hit?

The ground attack

Cosmic rays can deep in the earth’s atmosphere, atmosphere during the collision with molecules. The large hadron collider on sensitive particles can detect event generated cosmic particles.

If the computer’s processor is the direct impact, cosmic data will be destroyed, causing error in calculation. Sometimes, these errors might not interrupt you Wii game on jump hold, even to people’s life in danger.

On October 8, 2008, the airbus aircraft qantas strange behavior is thought to be caused by particles. This plane suddenly appeared twice rapid subduction succession, respectively for 200 metres and 120 meters. Before being regain control, caused a flight attendant and many passengers badly. Investigation shows, computer work on the new program is normal, but in the calculation of the computer has caused by cosmic rays that “bad”.

Computer processor maker Intel has announced plans to protect its increasingly powerful, but in the cosmic ray is becoming more and more fragile under the chip. Detector will detect the high-energy particles impact and ordered the microprocessor to handle the calculating process of interference, thus to avoid mistakes.

For only a single chip computer, the cosmic rays and not a big problem. They have the potential calculation errors occur once every few years. But for 10,000 pieces of super computer chips, every possible 10 ~ 20 times.

More research is needed

So if Toyota has become the first by cosmic rays events affect auto enterprise? After all, Toyota automobile electronic control in the field has been the world’s leading for on-board computer increased a lot of sensitive processor. Will they are high-energy particles under the invasion of fan?

Someone really doubt cosmic rays may cause many “accelerated” suddenly. It is not impossible, so need to carefully, especially our further investigation of computer technology are becoming increasingly weak today.
