you know,if one of the comet start forwarding towards our planet or one of the flare of sun start reaching towards our planet, how come they would be able to save this planet from this certain destruction?

i think they can only inform us in advance "ohhh one comet is going to strike against the Earth run run , go go go " this would be the altimate "action" from space centres and space scientists for us. Is this so miserable? If one of us would ask them , how long you were in space and what have you achieved? their reply would be "we took alot pics and movies of our fixed planets and sun" but sadly we couldnt save you from this disaster.

Only saving their satellites from this risk isnot enough for the existance of such probe in space. Saving lifes would be considered one the biggest achievement. But i think science is just paying more time on just "observation"
let i tell you the power of this science "science is not yet able to build a small fly" open chanllenge!

This is absolutely true -- I saw something very strange yesterday. Standing in a grassy knoll, thousands of seagulls were flocked closely together. But what was strange was most of them were standing still and facing the same direction! It was like they were all watching a concert or something. Can anyone explain this?

It seems that a thing with no mass ceases to be a thing. Also, if they has no mass, how do we know they exist? If it is something along the lines of "they exist as energy and not as matter" as I suspect the answer might be, then why call them particles, and classify them in the same category as things with mass (like protons)?
