well first off Einstein's didn't think u CAN travel at, or above, the speed of light with anything that has real mass. because if car approaches the speed of light, its resistance to acceleration (mass) increases so that it would take an impossibly infinite force to actually reach the speed of light. so basicly u can't ask this question :P so hypothetical: As you approach the speed of light with your headlights on, you would still measure the light beam racing away from your car at 186,000 miles per second (the speed of light). A 'stationary' observer watching this happen, though, would not then measure the beam's speed at almost twice the speed of light . Relativity says that all observers always get the same measurement for the speed of light.
While that may not sound logical or plausible, it happens because what we normally think of as fixed concepts--length and time--are both variable at high speeds. If you observed a car travelling past you at close to the speed of light , its length in the direction of travel would appear shortened and the passage of time on board would appear slowed down.
If a petrol Station is open 24 hours 7 days a week 365 a year...
Why does the door have a lock? : there is no petrol station open 24 hours 7 days a weeek for 365 years cause there closed on national holidays or in case of emergency the will close and then they can lock the door

Doctors are technically not professionals, there are too many things that can go wrong with medicine. Have you ever heard the expression, "Medicine is NOT an exact science"? That's what they mean by that, it's not exact therefore it is considered a 'practice', not a 'profession'.

Because the plastic in the bottles deteriorates and leaches icky chemicals into the water.
If water remains moving, bacteria has a tougher time growing. Water that stays still (stagnant ) is full of bacteria (legonella)which is why you should never ever drink water that is standing.
Professor Allen Walker Read of Columbia University, "finally unveiled its (O.K.'s) origins in a series of magisterial articles in 'American Speech' in 1963 and 1964.What Professor Read discovered was that the abbreviation arose in a humorous manner at a time when Americans were indulging in a great deal of wordplay, including abbreviations, acronyms, puns and intentional mispronunciations and misspellings. The earliest example of O.K. that he unearthed (and it is so far still the oldest known specimen) is from the Boston 'Morning Post' of March 23, 1839. It appears in connection with a note by the paper's editor, Charles Gordon Greene, about a visit to New York of some members of the local Anti-Bell-Ringing Society. (The A.B.R.S., as it was usually known, was itself something of a joke, having been formed the previous year to oppose -- its name to the contrary -- an ordinance of the Boston Common Council against ringing dinner bells.) In an aside, Mr. Greene suggested that if the Bostonians were to return home via Providence, they might be greeted by one of his rivals, the editor of that city's 'Journal,' who 'would have the 'contribution box,' et ceteras, o.k. -- all correct -- and cause the corks to fly, like sparks, upward.'.Thus, it appears that O.K. was invented, possibly by Greene, as an abbreviation of the jocular 'Oll' or perhaps 'Orl korrect,' meaning "All right.' This explanation would seem farfetched, except for Read's finding that it dovetails with such coinages of the period as O.W. for 'All Right,' as though spelled 'Oll Wright' (this appeared in the Boston 'Morning Post' in 1838, the year before O.K.'s debut); K.G. for 'No Good'; and K.Y. for 'No Yuse.'."

My turn..
Simply put, the helmet was necessary to pilot the aircraft. Inside the helmet was the communication gear, microphones & speakers, and the goggles were attached to helmet as well. It wasn't a crash helmet per se, but merely a leather cap, crash helemts were really only worn by bomber crews and then only in extreme circumstances.
*stops halfway up the mountain to admire the view*
with light sources as intense as a sun it is generally very difficult to get a double shadow, the sort of thing you see in football matches under floodlights etc. Where a section of shadow from one sun would exist, the second sun cancels out this shadow to some extent. Hence the shadows we actually have are a combination of the 2 seperate shadows, one form ech sun, and this is why they look a little more unnatural and distorted than usual.
I have one, you have one. If you remove the first letter, a bit remains. If you remove the second, bit still remains. After much trying, you might be able to remove the third one also, but it remains. It dies hard!
