It's well known, and has been confirmed in thousands of experiments over the
past hundred years, that an object's mass increases as its speed increases.
That's true even if the object is you.
Since it takes more force to accelerate objects with more mass, as your speed
increases, it takes more force, and more energy, to increase it more. Eventually,
as you approach the speeed of light, your mass is approaching infinity, and the
additional energy required to speed you up some more is also approaching infinity.
That's one reason ... the amount of energy required to boost you to huge speeds.
Another reason is the amount of time. How much acceleration can you tolerate ?
3 Gs ? 5 Gs ? Let's say you're a superhero, with fingernails of steel and a gut to
match, and you can live and breathe and enjoy yourself very well with a constant
10 Gs ... meaning you can walk around and function even though you weigh
somewhere between 1,500 pounds and a ton.
At 10 Gs acceleration, it takes you 35days 9.1hours to reach 10% of the speed of light!
No, because the orbital is really just an abraction - the electron isn't racing around the orbital like a racecar, so there isn't a speed. The orbital is a better measure of the electrons potential energy.
None can.
the light speed are very fast so light easily reach on earth
At a distance of about 12.88 billion light years, it is unlikely that it will still be there when you reach it. At a speed of "c" (Speed of light) you would still be unlikely to be able to reach it, as most further galaxies are receding at close, if not faster, than the speed of light. If however, the Universe was static, it would take about 12.88 billion years to reach it at the speed of light. As this is not possible, lets put this into perspective. The fasted man made craft is Voyager 1, so far travelling at 35,700 mph. At that speed, it would take a mere 241,900,000,000,000 years to reach IOK-1.

Neither, mass can never reach the speed of light, this question also contridicts the theory of realativity.
As far as we understand physics today, we won't ever be able to get to the speed of light. The faster you go, the harder it gets to go any faster. So that last little fraction will "always" remain impossible - or at least until someone invents a whole new branch of physics. So the only ships that can reach the speed of light are the ones in our imagination.
You can't travel at the speed of light. It might be possible, in theory, to approach it, but not quite to reach it.
Because light has no mass.
Electrons are able to travel close to speed of light.
It would never reach the speed of light because things with mass can't move at the speed of light. However, it would eventually get as close to the speed of light as you want.
No such thing would happen. Matter cannot reach the speed of light, only massless things can (and they cannot travel at any other speed than the speed of light).
