Speed of light and bending time

Click For Summary
SUMMARY

The discussion centers on the relationship between the speed of light, time dilation, and the concept of time travel. The speed of light is established as 299,792,458 m/s, and it is noted that as an object approaches this speed, time appears to slow down for that object relative to an external observer. The concept of time dilation is clarified, emphasizing that it is a perception experienced by external observers rather than the traveler. The discussion concludes that relativistic speeds do not simply add together and are governed by specific formulas that ensure they never exceed the speed of light.

First, i want to state that i am very interested in physics, but i have not done any education on this subject, except for science class, which only covered the tip of the iceberg of information we now have.

Second, i want to excuse myself for possible faults in data, I'm happy if you correct me, to help me out of my paradox. I'm also happy if you confirm my idea ;)

3rd, my post is longer than expected, i note a lot of data to make sure my way of thinking is right, again, correct me if I'm wrong.( in theory, not in grammar! :P)

I have done some research on the internet to find out more information about timetravel, and the constant speed of light.

We measure speed in units of distance and time, like we state that the speed of light is 299792458 km/h.

We also believe that as we go faster, time goes slower. If i would travel at lightspeed, my watch would tik slower than a watch on earth, thus i am traveling to the future.

Since my body needs to circulate blood, and my atoms need to vibrate( for temperature), i would die, because my temperature goes down to 0 kelvin( else my 'forward' vibrating atom would go faster than speed of light, which is impossible, at least, that is the theory), and my blood can't circulate forward, due to same restrictions.

But i believe that this theory about the constrant maximum speed of light has a flaw, in combination with the time traveling concept. I checked http://www.astrosociety.org/education/publications/tnl/71/howfast.html to see the best indication of our current speed, which is around 2.1 million km/h. This means we already go around 583,33 km/s( more than 1/514th of lightspeed). In our perspective, a second is a second, so everything that moves can be measured with m/s or km/s, etc. But if we would go faster, our second slows down, we don't know to what point exactly( at least i don't), a very slow flow of time or a stop in time. If going faster slows our watch, then going slower (to the absolute 0 velocity)would make our watch go faster.

So let's say, at 583.33 km/s, 1 second is a second, if we go twice as fast( which is a big achievement already!), then a second from traveling perspective, might be 1.1 second on earth, but how do you measure speed then? More extreme example, let's say we move so fast, that 1 secont in traveling perspective, would be 5 seconds on earth. IF you were at the velocity which we take to be the absolute maximum, than we would be traveling at 299792458 m/s in traveling perspective, but seen from earth, its only 1/5th as fast!? How do we solve this issue?

I would suggest that you continue your studies, since you have taken in a mish-mash of concepts and misunderstood them.

Time dilation does not occur to the traveler, it is a perception of external observers. That is, YOU do not see you clock tick abnormally, nor do your physical processes change. External observers DO see that and yes you do in fact travel into the future faster than those who are not accelerating, providing that you return to their frame of reference.

Relativistic speeds do not add, they are governed by a different formula and never exceed c.
