Exceeding the speed of light O_O

thats pretty cool

Space Travel.. If they somehow apply it to Space Shuttles.. Plus my science teacher told me, humans are unable to survive the speed of the speed of light. Unless we somehow genetically engineer ourselves to tolerate extreme speeds, we will not be using that type of speed any time soon.

True, the human body wouldnt be able to withstand then amount of g-force from moving at the speed of light, but in space (where there is little no gravity) it may be possible. You would have to accelerate once you reach a safe distance.

Also, I dont think time travel is possible. How does moving extremely fast actually alter time? Now we jump into paradox territory. If we could travel in time, wouldnt we know by now if time travel was possible, since they could come back and tell us if it was?

I tried asking myself that quite a few times. In the end i think it was just another foolish idea when someone thought that time goes on with Earth's spinning and revolving around the system. They probably thought the going in the opposite direction with extreme speed would mean going in the past ._. Just my imagination.

Perhaps going back in time and changing the course of events creates an alternate universe that goes off on its own path. That way the second someone went back in time another universe would be created while the universe we're in is unaffected.

I´ve been thinking about this possibility many months ago and i´ve heard about this last week.

The g-force could be countered if the conditions in a vessel generates an equal and opposite g-force netting a net zero one, or something along those lines. I just got up and am tired, so that's worded poorly. A buffer would have to be made I think, but honestly I'm too tired to remember exactly how it works right now. I do know that it can in theory though.

Regarding increased speed and time, this goes back to special relativity, though it fits in general since special is just a special case of general relativity. Anyway, look up (I guess google will work, "time dilation and special relativity" maybe) something called time dilation and look for the twins paradox from Einstein. It won't let you travel back in time, but the passage of time for your reference frame will be different based on your speed. There are ways to travel back in time in general relativity that don't require anything other than the speed we have now.

Of course, according to general relativity, space and time are one, so every event in the past, present, and future are occurring simultaneously, lol. Thus, it's not so much that you're traveling "back" in time, so much as you're traveling to a different Cartesian coordinate in space-time. Here's something funny, right now, we're not yet born, alive, and dead, as an application of what I told you based on the Cartesian point we perceive. Thus, at this point, you should question free will I suppose.

Peace

lol have you ever seen the episode when superman reversed time by spinning earth backwards?

They did discover these neutrinos.. and they do travel faster than light but not by much, light travels at 299,792 km/s and neutrinos travel at 300,006 km/s xd

 

[Acnologia..]

If you did traval at the speed of light i don't think u would be able to get far that is if u want to see the end of an expanding universe
