A physics stump for me

Discussion in 'Off Topic' started by KingReese627, Dec 2, 2014.

  1. So me and brother just had conversation about physics about a theory.

    So the theory is that if u can get to the speed of light theoretically you can essentially live forever.
    Now here's the stump, what if the Earth completely stopped like all motion we could still continue are motion though, but the Earth itself stopped. Would we die? Because, seconds could turn to hours and hours to years and years to thousands of years and like that in a blink of an eye we'd be dead!

    Or would we? Or to us would life continue on the same but faster and would we realize it?
     
  2. You'd still die as time would inevitably pass it would feel long for you, but you'd still go.
     
  3. Hmm didn't even think about that
     
  4. I agree partially with your statement, though isn't the magnetic field a result of massive concentrations of liquified ferromagnetic substance in the core of the earth?

    And isn't the magnetic field part of what contains the atmosphere, in conjunction with the earth's mass, resulting in a gravitational attraction?

    On a side note, half or so of the earth would never see light, and the other half would be pelted with constant light, likely resulting in a rapid decay of the magnetic field, as well as a horrible change in the circadian rhythm of the two populi.

    Just speculation on my part, hope it helps OP
     
  5. Time cant stop or reverse but can slow down
     
  6. Earth stopping wouldn't change time. Time is linear and continues regardless of earths rotation. I think what is misconstrued with your theory is that seasons are caused by the rotational elipse and non-centered nature of said elipse... In short Earths rotation has nothing to do with the passage of time.
     
  7. Since you asked, I might as well provide.
    I consulted the googs.
    You are welcome.

    The probability for such an event is practically zero in the next few billion years. If the Earth stopped spinning suddenly, the atmosphere would still be in motion with the Earth's original 1100 mile per hour rotation speed at the equator. All of the land masses would be scoured clean of anything not attached to bedrock. This means rocks, topsoil, trees, buildings, your pet dog, and so on, would be swept away into the atmosphere.
    If the process happened gradually over billions of years, the situation would be very different, and it is this possibility which is the most likely as the constant torquing of the Sun and Moon upon the Earth finally reaches it's conclusion. If the rotation period slowed to 1 rotation every 365 days a condition called 'sun synchronous', every spot in the Earth would have permanent daytime or nighttime all year long. This is similar to the situation on the Moon where for 2 weeks the front-side is illuminated by the Sun, and for 2 weeks the back side is illuminated. This situation for the Earth is not the condition of 'stopped' rotation, but it is as close as the laws of physics will let the Earth get.

    If it stopped spinning completely...not even once every 365 days, you would get 1/2 year daylight and 1/2 year nightime. During daytime for 6 months, the surface temperature would depend on your latitude, being far hotter that it is now at the equator than at the poles where the light rays are more slanted and heating efficiency is lower. This long-term temperature gradient would alter the atmospheric wind circulation pattern so that the air would move from the equator to the poles rather than in wind systems parallel to the equator like they are now. The yearly change in the Sun's position in the sky would now be just its seasonal motion up and down the sky towards the south due to the orbit of the Earth and its axial tilt. As you moved along constant lines of Earth latitude, you would see the elevation of the Sun increase or decrease in the sky just as we now see the elevation of the Sun change from a single point on the Earth due to the Earth's daily rotation.
    For example, if you were at a latitude of +24 degrees North in the Summer and at a longitude where the Sun was exactly overhead, it would slide gradually to the horizon as Fall approached, but since the Sun has moved 90 degrees in its orbit, it would now be due west. Then as we approach Winter, you would now be located on the dark side of the Earth, and would have to travel in longitude to a location 180 degrees around the Earth to see the Sun 1/2 way up the sky because in the Winter, the Sun is 48 degrees south of its summer location in the sky. It's a little confusing, but if you use a globe of the Earth and orient it the right way, you can see how all this works out.
    As for other effects, presumably the magnetic field of the Earth is generated by a dynamo effect that involves its rotation. If the Earth stopped rotating, it's magnetic field would no longer be regenerated and it would decay away to some low, residual value due to the very small component which is 'fossilized' in its iron-rich rocks. There would be no more 'northern lights' and the Van Allen radiation belts would probably vanish, as would our protection from cosmic rays and other high-energy particles. This is a significant biohazard.

  8. I don know what part of this statement to correct first...

    A crash course in physics would be great for you.

    Earths dipoles have been switching positions many times since collision calescence,yet life kept on going...

    Earths magnetosphere is just one layer of our atmosphere so saying it's absense would render us exposed to gamma radiation from the sun is quite ludacris. We should be more worried about nitrus and sulfur oxides punching holes in multiple layers of our atmosphere first.
     
  9. The atmosfear
     
  10. The northern lights are an effect generated by pollutants not the magnetosphere. Also our mass creates gravitational pull of the moon and the moons mass tugs on us hence our tides. Yes we spin on an elipse... Hence elipse...
     

  11. Glad you can butcher someone else's information without citing it properly

    Let me start by saying pollution has always existed. Nitrus oxide emissions (nox) a pollutant is a big reason there is so much suspended in our atmosphere which allows these reactions to occur

    Second the moons MASS is what causes the tides not the moon itself.

    Also the magnetosphere is the catalyst for said reactions not the cause
     
  12. Firstly, you wouldnt live forever by going at the speed on light. Light u see, still has a speed, it isnt just infintely fast it's just the fastest thing.

    If u moved infinitely fast u would effectively love forever.

    If we were moving 99.9% the speed of light, possible but not managed, your 1 hour would be i think it's 1 or 10 or 100 years on earth? So you would appear to live significantly longer than everyone else, but you yourself would still age depending on what time you are experiencing. Just to everyone else it appears as though you're aging massively slower lol.


    And if the earth stopped spinning, life of earth would cease to exist. Not immediately but quickly.

    Firstly the tides would be super messed up because the moon would still be orbiting, and since the earth wouldn't be spinning the tides would get much faster very quickly and cause a lot of flooding.

    Next off, Uhm i dont remember what else would happen, ask a physics teacher they'll be more than happy to answer your questions and they'll probably end up giving you more :lol:

    Oh and btw, most of the stuff on here will be complete bollocks, even im not sure about what i said other than the stuff bout aging, ask a teacher, it's much safer xD you'll get pot heads on the internet trying to convince you that time isn't real, which, breaks every law of physics they try to use to prove it isnt :S
     
  13. :roll: A question about the sciences. You can't even use proper grammar, mate. You expect to understand physics?


    It's "my brother and I"
    Not "me and my brother"

    :lol: :lol: :lol: :lol: :lol: :lol: :lol:
     
  14. Urrgghh disgusting read. The only post that made sense scientifically and attempted to answer the question, was made by clumsy reaper . Firstly speed, time and distance are all relative to the observer. So if u could travel close to the speed of light, time to you would appear unchanged, and if you could somehow (hypothetically speaking) see a clock that is on the earth, It would be ticking faster. but to an observer on earth, your clock would be ticking slower and there's would be unchanged. Hence the theory of relativity. There is no absolute distance or time, it's all relative.

    And secondly, the earths motion wouldn't have to stop, so how this come into the argument I have no idea. And even if it did stop, it has its orbital motion, I.e the velocity that it orbits the sun. and it has it's rotational motion, the speed at which it rotates on its axis. If it were to stop orbiting, it will fall directly into the sun under the gravitational attraction. If it were to stop spinning, Gravity would not cease to exist. But either way, pointless addition to the argument. A spacecraft could theoretically reach speeds close to the speed of light, but the earth wouldn't lose all motion as a result.
     
  15. If the earth stopped moving but you didn't, you'd be flung Into space about 1000 mph and you'd die horribly.

    I don't think that's the answer you're looking for.

    First off, saying that if you could theoritaclly reach the speed of light would allow you to live forever is a silly thrown because it cannot be done.

    The difference between the speed of light and your current velocity is refers to as "Tau" in mathmatical terms. Attaining tau zero would require more energy than exists in the entire universe, so, your theoretical construct is meaningless. Sorry :-(
     
  16. you don't really understand the concept. the closer you get to the speed of light, the slower time passes relative to that which is moving at a slower rate. time would seem to pass normally for you, not matter the speed at which you are travelling.

    @moose, he meant "if we stopped moving through space, but we weren't frozen in place on earth". he believes that the velocity of the earth through space "slows" time by a significant amount.
