The energy of a particle diverges to infinity as it approaches the speed of light. Since we can never have infinite energy for a particle, the speed of light cannot be reached.
Now say somehow you were able to go faster than the speed of light (i.e. the v in the above equation is now greater than c the speed of light). The equation will then give us a square root of a negative number on the right hand side (which is an imaginary number.) Well I can factor out the imaginary unit number (i or the square root of minus one) and plot the result on the same graph. This.
Our current understanding of physics and how light travels excludes objects from reaching a velocity greater than lightspeed, but it does not exclude the possibility of space itself traveling at or beyond that speed. In fact, some people who have examined the problem claim that in the early universe, space-time expanded at superluminal speed, if only for a very short interval.So the distance between two objects can be increasing faster than light because of the expansion of the universe, but this does not mean, in fact, that their relative speed is faster than light. As was mentioned above, in special relativity it is possible for two objects to be moving apart by speeds up to twice the speed of light as measured by an observer in a third frame of reference.Rapid acceleration and deceleration can be lethal to the human organism Even Orion won’t represent the peak of our speed potential, though. “There is no real practical limit to how fast we can.
Now, special relativity predicts (and it is in fact very well confirmed) the phenomenon called 'time dilation', which simply means that a clock in motion relative to an observer seems to run slower than a stationary clock; that is, the seconds on the moving clock seem to get 'stretched out'; the closer the velocity to the speed of light, the greater the effect. Also, it is noteworthy that this.
Although Einstein's theories suggest nothing can move faster than the speed of light, two scientists have extended his equations to show what would happen if faster-than-light travel were possible.
Why can nothing exceed the speed of light - John (age 30) Lehigh Acres, florida. A: Hi John, That is a remarkable question! According to Einstein's Theory of Relativity, it turns out that if an object could travel faster than the speed of light, extremely weird effects could be observed: An observer traveling with the object would be able to observe an effect before its cause! That means, for.
One common answer is called the observable universe, and it's defined by the speed of light. Since we can only see things when the light they emit or reflect reaches us, we can never see farther.
Although Einstein's equations tells us that nothing can be accelerated to, or beyond, the speed of light, the photon exists at light speed, it does not accelerate to it. As a further point of interest, Einstein's equations do not rule out the possibility of particles that exist at faster than light speed, which would result in them being unable to travel at less than light speed.
Ultimately, this means that we could only reach the edge of the observable universe if we develop a method of transport that allows us to either 1) Travel faster than the speed of light (something.
Physicists generally believe faster-than-light travel is impossible. Relativistic time dilation allows a traveler to experience time more slowly, the closer their speed is to the speed of light. This apparent slowing becomes noticeable when velocities above 80% of the speed of light are attained.
As an object approaches the speed of light, its mass rises precipitously. If an object tries to travel 186,000 miles per second, its mass becomes infinite, and so does the energy required to move it. For this reason, no normal object can travel as fast or faster than the speed of light.
The US military funded a report that describes using negative or dark energy to warp the fabric of space and travel 100 times the speed of light. A theoretical physicist says the concept is not.
Everyone thinks it would be cool to travel at the speed of light, which is why scientists devote their lives to working out if it would be possible and NASA is trying to develop its own warp drive.
Light travels at a blistering 670 million mph — a speed that’s immensely difficult to achieve and impossible to surpass. But some particles are being accelerated to incredible speeds, some even reaching 99.9% the speed of light. Studying these superfast particles can help protect missions exploring the solar system.
