I agree with Imperial Thinker's statement , can you imagine ask Albert Enistien about a legimate reference to support his theoretical ideas in 1905, yet we all know now that he was right, anything is possible my friendCan you please provide a legitimate online reference to support your theoretical statement?
Yes I can, and he would support his theoretical ideas.can you imagine ask Albert Enistien about a legimate reference to support his theoretical ideas in 1905
That shows that you don't understand how science works. No, anything is not possible, and if you admit that Einstein was right, you can't agree with Imperial Thinker's statement, because what he says is that Einstein was wrong.yet we all know now that he was right, anything is possible my friend
In our world, the only way that I could think of is to evaporate every massive particles of an object into photons, such as annihilation and then pair creation, which travel at c. In that sense, I do not know any photon based organisms and I would assume the photons created not alive.All we have is our physics and our world, in which there is no possibility to travel at the speed of light.
Sure, and his answer would be to simply give you the legitimate peer-reviewed references that he himself published in 1905.can you imagine ask Albert Enistien about a legimate reference to support his theoretical ideas in 1905
No, theoretically and experimentally the answer is no. See below for why.Theoretically , yes. Experimentally, no one knows.
A better way to say it, to avoid questions about whether the term "alive" could be applied to something made purely of photons, is that, to anything moving at c, whether a photon or anything else, the concept of "time" (more specifically "proper time", the time elapsed on a clock carried with the object) is meaningless. And since the concept of "living forever" depends on having a meaningful concept of time, the concept of "living forever" is also meaningless for anything moving at c. This is true both theoretically (because in the math of relativity, photons, and other objects that move at c, move on null worldlines, which do not have a meaningful concept of proper time) and experimentally (because the energy-momentum relation for photons, which is what verifies that they have zero invariant mass and move on null worldlines, has been extensively confirmed in experiments). So the answer to the OP's question is "no".At light speed, you would not be alive.
Even in this scenario, you would still only experience a finite lifetime, as you say. At some point that finite lifetime would end, and the universe, assuming it is going to keep expanding forever, which is our best current model, would still be there. It might be a cold, dead universe, with all stars long since burned out, but it would still be there.you could manage to essentially outlive the universe.
Well, you could live as long as the universe, with no caveats if you had magic drive that could accelerate at more than constant g, as long as desired. For eternal uniform acceleration, though speed approaches c, proper time still approaches infinity. However, posit, e.g.Even in this scenario, you would still only experience a finite lifetime, as you say. At some point that finite lifetime would end, and the universe, assuming it is going to keep expanding forever, which is our best current model, would still be there. It might be a cold, dead universe, with all stars long since burned out, but it would still be there.
If the universe will eventually recollapse to a Big Crunch, then you could, in theory, manage to live until the Crunch (but not beyond it, since the universe would end there and you with it).
I'm not sure that the OP meant to include these possibilities in his question, but he's welcome to weigh in.
If you never slowed down and returned, you would see everything else actually time-dilated. To you, things outside would be moving and aging slower than usual (once you account for the Doppler shift effects). If you moved arbitrarily close to the speed of light; however, you will see distances contract to arbitrarily small distances, so you will pass by things quite fast, stars would zoom right past you and become quite dense as far as you could tell.The question is not meaningless; it is an opportunity to explore.
You could - in theory - reach a speed arbitrarily close to light*. If you were to do so, you could manage to essentially outlive the universe. That's pretty close to forever. Of course, you would still only experience the same century lifetime, more or less, but you would be able to witness the universe aging and dying outside your spaceship window.
