If you travel at light's speed, 186,000 mph, then what happens?

Question

I heard that nothing could practically travel at the speed same as light. But it is theoritically proved that even if someone/something could actually travel that fast, Time wouldn't have any effect on it/him.

Interestingly, if someone travels at more speed than light, Time would go backwards for him. So the speed of light is a constant speed, a zero point, and related to time.

My question is, is all this true? or partly true? Anyone shed some light on it if know about it?

Answer 1

Nothing will mass can ever (even in theory) travel at, or faster than, the speed of light in a vacuum.
As an object approaches the speed of light seen from an outside observer, it takes more and more energy to accelerate the object. It would actually take an infinite amount of energy to accelerate an object to light speed, and in the entire universe there is no an infinite amount of energy.

As on object approaches the speed of light, as seen from an outside observer, time seems to slow down for them (eventually coming to a complete stop if they would to reach light speed). However, from the object's own frame of reference, time would seem to behave like normal...only when an observer moving with the object looks out on to the rest of the universe do they detect something unusual. As the person approaches the speed of light (as measured from on outside observer) they see the rest of the universe speed up...eventually moving infinitely fast if they were to achieve light speed, which they cannot.

It is always important to specify the reference frame which one is making the measurements of the object's speed...there is no universe or absolute reference frame...all speeds are relative to the observer and in any reference frame faster than light travel is prohibited and the speed of light is always measured to be the same.

Answer 2

Humanity hasn't figured out how to travel at even 10% the speed of light. So, why are you even contemplating traveling faster than the speed of light. If it takes all of the mass and energy in the universe to get to the speed of light in the first place ? Faster than ight speed travel is like trying to get perpetual motion;Something for nothing. Don't forget that you would need some kind of a space shuttle capable of withstanding the friction of the particles at such a high speed. The craft would melt and so would you. It's never been done. Theoretical Physics is fancy foot work. But, lacks the punch value of experimental proof. Which is more often demostrable in other disciplines or fields;Electricity & magnetism,thermodynamics,Chemistry,mechanical engineering.Theories are dreamy kinds of things. But,dreams aren't always possible in the real world. Science and technology advances only after the final verdict or experimental proof. It took us forever to begin testing previously so called truths laid down by ancient Philosophers about matter,physics & even biological ideas. These guys simply assumed facts about the laws of nature and it was believed for thousands of years before these "truths" were finally tested and disproved. If someone says something is theoretically possible... They haven't really got a clue until they've tried it. Ever notice how many engineering,architectural,medical,marketing,movie and military ideas.plans and strategies tumbled before the old men.Who thought it was a good idea.Because,they've got,status,credentials,money or a diploma on their wall. We have engineers who are so backwards nowadays.They want to build trans continental highways, trans atlantic tunnels,bigger this that and everything. It only leads to bigger tragedies. Like the world trade centre. Titanic,Irsish potato famine,Hiroshima and Nagasaki nuclear blasts,New Orleans flooding,blood contaminations,But,they insist and everyone just follows.

Answer 3

You are discussing pure theory. The closest partical to come close to the speed is a meson. I doubt that time travel will ever be possible. According to Einstein's theory, the faster you go toward light, you will: 1. grow longer along the axis of the direction you are traveling 2. get more mass (heavier) 3. Time will slow down (NOT REVERSE).

Now, getting heavier is where the big problem is. You would need more fuel to get you to go faster and faster. Then you would continue to get heavier and heavier. You would need more fuel. It is the theory now that there isn't enough energy in the world to push matter to or beyond the speed of light.

Answer 4

Quck Short: Think of a clock face. Big hand on the 12, little on 1 (1 o'clock) it's one o'clock cause the light bouncing of the clocks hands is going into your eye and you see it. If you keep staring at it time will change of course. Now stare at the clock and run backwards at the speed of light, the light off the clock to your eyes is the same one that says one o'clock. Time has stopped. If you could faster than the speed of light you can probly catch the light to your eye where it say it 12 o'clock. Problem is the faster you go the heavier you get you get to a point where you are to heavy to even move that fast. There are many more examples to explain but they will get long.

Answer 5

yes it is possible to travel faster than the speed of light. think of windows on your computer and how you can access all the information in the universe at a touch of a finger. check out the following:

I just completed a four day, two level course on matrix energetics taught by Dr. Richard Bartlett in San Diego, CA. Wow! - Go!

Answer 6

Special Relativity states that ones movement through space and their progression through time are inversely proportional. If you speed up your movement through space, you slow your progression through time. This has, in a way, been experimentally verified. Two identical clocks, one was kept stationary, the other flown into space with a shuttle. Upon comparing them later the stationary clock was ever so slightly ahead of the other clock. Is this hard evidence? You decide.

Answer 7

i think time does has an affect because it takes 1 billion years for light of some stars to reach the Earth.

Answer 8

Choose your 'coordinate system' wisely. He is not aging in relation to those that are not moving. If we were to follow his frame of motion, then he would be aging.

Someone validate me, i might be wrong.

Answer 9

u would get a speeding ticket for sure!

Answer 10

You put on a helluva lot of weight, something like INFINITEY.
Theoretically PROVED ? I must have been asleep during the demonstration when it was proved.
