With a burst of solar flares and Northern Lights, the sun is waking up from a three-year slumber.

If authorities ever announce that solar flare is about to fry us all,

I want the narrator of this video to announce it.

His soothing voice will make it look like as an exciting & magnificent natural event that unfortunately has the side-effect of eradicating all living things!

it takes about 8 minutes for "rays" a.k.a. electromagnetic wave to travel to earth, not 6 minutes. particles will not travel at the speed of light (quite a bit slower in fact) so my guess is that it would take quite some for them to get to the earth.

Good video!

This is an invitation to see an artist theory on the physics of light and time!

This can be based on just two postulates

1. Is that the quantum wave particle function Ψ or probability function represents the forward passage of time itself

2. Is that Heisenberg’s Uncertainty Principle ∆×∆p×≥h/4π that is formed by the w-function is the same uncertainty we have with any future event within our own ref-frame that we can interact with turning the possible into the actual!

did anyone else giggle when they heard the name: Dick Fisher? or am i just childish?

[NoTr0llz]

When he said "Dick Fisher" I burst out laughing xD

[ASFALT21]

this is sad

Useless stuff like new vid from some "popular" artist gets millions of views A DAY and stuff that REALLY MATTERS get only 25k in 2 WEEKS

What is humanity coming to?

Watch the starting or "Idiocracy" movie to find out -_-

now (21.55 gmt) I watched the sun via satellite sterreo.

A lot of interesting events on the sun at this time.

YA ESTAMOS FRITOS. NADA DE PROTESTAS. QUE NOS DIGAN EN QUE FORMA NOS AFECTARÍA SUSTANCIALMENTE ESTA ACTIVIDAD SOLAR. CUALES SERÍAN LAS MEDIDAS QUE TENDRÍAMOS QUE TOMAR PARA QUE NO AFECTE NUESTRA SALUD?.

[James Rodway]

Isn't there a way to create a magnetic field big enough on the surfas of earth to fill the hole that's in the earths field ??? There for protecting us from a massive solar storm

[Lux Divine]

Why should they announce something we can do nothing about?

[Lux Divine]

We seem to survive by mere chance : either asteroids threatening to kill us or our sun trying to burn us alive or to send its flares to our magnetic field thus we have earthquakes and tsunamis! lets pray that earth find another gentle sun! LOL

is it so dangerous?can someone explain me it?
