In the above link to the pinned thread, iko upuus mingi inasemwa, sanasana na @Doc oga ati Einstein is nothing, ati Tesla is the real McCoy nyef nyef nyef... chunga maongeo yako. As a scientist myself, I know and fellow scientists know that Albert Einstein is the real OG. For now.
Ladies and gentlemen, let me take you through an important lesson in science. It is about space and time. So @Magdalena, @The.Black.Templar and elder wetu @Field Marshal makinikeni. Especially, the latter. I'm showing him a secret to halt aging and in the process let his vitukus overtake him to Valhalla.
Quite a long read but is factual and a bit interesting.
Here we go.
Our universe is of inconceivable scale. Yes, that you all know. Haina mwisho. You can't say that the edge has a wall or anything like that. It is punctuated by at least 70 sextillion stars. That's more than every sand particle on earth. An absurd number that defies human comprehension. Despite the abundance of these cosmic landmarks, there's the irony that concentrated matter are far between. For example if each star was shrunk down to the size of a sand particle, then the distance between two sand particles would be 10km. Kwa 'ground' that distance is 4 light years.
This distance is too immense, it will even pose a challenge to our most sophisticated and remotest spacecraft - Voyager 1 (I did a piece on this craft humu kijijini sometime back). Currently at 17.2Birrions km and travelling at 17km/s it'll take another 80,000yrs to travel the 4 light years to get to our nearest star - The Alpha Centauri (I'll abbreviate it as AC). To get to the next galaxy it'd take 500,000 times longer. Mind-blowing, isn't it? Na bado so changamsha akili. Faced with such distances, such epic timescales, it seems the universe forbids man from the dream of exploring the depths of space. With challenges like these we're forced to dream of the possibility of creating wormholes. Shida ni moja. Wormholes are theoretically impossible. Yes, you heard right. Not just practicality impossible but also theoretically impossible! The famed Halo Drive wouldn't get you there.
Remarkably, there's a trick that uses proven physics that might allow a person to travel between even distanced galaxies on a human lifetime. But like making a deal with the devil, it comes with a steep price that you may not want to sign up.
From Einstein's theory of relativity, I'll take you though how This is Guka can stop aging and in the process see his great great great grandchildren age out and die before him. The trick is using a constantly accelerating armoured wingroad with heated seats.
Let's assume that FCP's wingroad can maintain an acceleration of 1g for as long as he likes. That means that it'll accelerate at 10m/s for each second that ticks by. For example, after 10 seconds it'd be traveling at 100m/s having covered 500m. Like I said we assume the wingroad can achieve such a feat. Let's also assume that the car has an incredible shielding and and as such can withstand cosmic radiation and impacts za huko deep space. At 1g he'll be pressed back against the heated seats at the normal gravitational force, so weightlessness wouldn't be an issue. Activities like eating, sipping WC and ferking a dirty tirried co-driver would be normal because of the artificial gravity.
The acceleration will be slow at first but will rapidly accumulate with time much like the way compound interest does. After 2 and a half hours Guka will be past the moon. A day and a half later, he'll be zooming past Mars. After 3 weeks he'll overtake Voyager 1 (started it's cosmic journey in September 1977). It will have left the solar system and doing 40mirrion miles per hour in the interstellar space. That's 6% of the speed of light, and much faster than anything man - made ever. Yes, it is fast but not fast enough for Einstein's theory of special relativity to come into play yet.
As he leaves the solar system his destination, our nearest star system, will come into view becoming brighter as he hurls towards it. Meanwhile, the sun will be a small speck dimming with every passing minute. The next one year will be uneventful, probably mundane with nothing special happening on board except for the changing brightness of AC. With each passing day, the craft will be gaining 2mirrion miles per hour speed.
Now it'll be impossible for him to videocall his other dirty tirries left behind because the time it takes for the radio waves to get to Kamangu and back will be months! Labda tubarua kama kitambo. So my advice? Beba zaidi ya mmoja. After 15 months, he'll be the first to cross the one light year(henceforth abbreviated here as LY) distance. He'll be a quarter of the way to AC but a third outbound journey time thanks to the ship constant acceleration. It starts getting a bit complicated nows.
By this time Guka will have achieved another milestone. And this is the gist of this thread. He will have achieved the Lorentz Factor. His factor will now be *two*. What this means is that the time dilation between him and his earthbound observing colleagues will be x2. They'll be seeing him moving in slow motion. From this point on, Einstein's theory of special relativity will have a greater influence on him because he'll be traveling at 87% the cosmic speed limit - the speed of light.
If there were no speed limits, Guka would have crossed the speed of light in 45 days from that day. Unfortunately, it has been proven rigorously time and again that it is impossible to cross the speed of light. Hadron Collider among other experiments have proven this.
Now here is where it gets tricky. So makinika. All observers, no matter their speed, will always observe the speed of light to be the same. This is very non-intuitive. If a horse chases down a moving train, then from the horse's perspective, the train appears to be moving slower than usual But relativity says no matter how fast that horse is running, if the train is a beam of light, it'll always appear to recede away at exactly the same speed - the speed of light. The horse can never catch up. If the speed of light is constant to all observers, then the mind-bending consequence is that space and time are not constant. They shift to accommodate this rule. And that's exactly what happens to Guka's wingroad. Time shifts such that observers back in Kamangu see him move slower than usual on board. Even the space shifts such that it appears the wingroad is squashed in length, and both of these scale with this Lorentz Factor. At this time, the factor is 2.
Wadau, I've explained the time-space continuum in very many words. I hope you're still with me. Ok, it gets a little bit more complicated.
HALF-TIME break for non-scientists!
***************************
From Earth's perspective the Wingroad will seem not to accelerate at 1g, even Guka will see his acceleration seeming to slow down as he approaches the speed of light but will still feel the 1g pin him back against the heated seats. Apart from that Guka and his dirty tirries will see time ticking by as usual, but they'll start noticing strange things outside the contraption. Looking back at the sun, they'll notice it fade into darkness much faster than they'd expect from distance scaling. By the time the Lorentz Factor goes past 2, the sun gets 10,000 times dimmer, only detectable by the wingroad's onboard telescope as a result of realistic abberations and time dilation effects. Think Doppler's Shift Effect and the seven components of visible light(Rainbow colors)
.Only the Infrared will be visible. Meanwhile on the other side towards the AC, the opposite will happen. Brightness will increase 10,000 folds because of the high energy UV light that will be hitting the windscreen of the Wingroad (told you earlier of the incredible windshield against radiation and space impactions). Not only that but the constellations ahead of Guka will appear distorted and warped into a kind of tunnel vision illusion.
In a very real way as Guka continues to accelerate ever faster, he begins to disconnect from the rest of the universe. But accelerating forever isn't an option because he doesn't have unlimited fuel on board. Also, at some point he'll have to slow down, step out and reconnect with the rest of the universe. So at halfway point he'll have to flip the Wingroad 180°, accelerate in the opposite direction and slow down as he reaches his destination. Sticking with his destination, which is 4 light years away, a beam of light from earth will take 4yrs. But because of time dilation effects on board, Guka will land his Wingroad on one of the planets in the AC system( like our own solar system) having aged just three and a half years. He shouldn't worry of outrunning a beam of light because back on earth the journey took him 6 earth years!
Still with me? Non-scientists need another break? OK take five.
*****************************
OK, back in this alien planet that they landed on. Maybe they spend the next few weeks exploring it, ferk around and then make the return journey. When they gets home, it'll be 7yrs for him and dirty tirries but 12 for the rest of the senators wenye hatukutoka nchi kavu. Not a bad timescale to complete a journey to our nearest star. Recall that his car started decelerating at the halfway mark, 2 LYs from earth, at 1.8yrs (his year, not earth years) while doing 95% the speed of light. Let's imagine that a fight broke out on board ( si yeye husema it happens often) and they decide they're not going to AC anymore, and that they want to use the momentum to go further, far further than anyone dreamt of. Now remember we were only considering a round trip scenario - we'll relax that assumption later, but now any journey is defined by four phases: Outbound acceleration, outbound deceleration, inbound acceleration and finally inbound deceleration. That would be seven years for the crew.
Supposing they go further out, our sun lives in the region of space of slightly higher hydrogen gas density than usual, a region about 30LYs across. The region is referred to as the local fluff. A ship which makes a round trip to the edge of this local fluff would age 13.4yrs during this adventure. Upon returning to earth, akina Guka will find that their kids will have aged those 13.4 yrs plus another 50! of course giving rise to some strange reunions. If Guka would still have some curiosity left, he'd want to go further.
The local bubble is a larger baloon where the local fluff resides. A collection of tens of thousands of stars spanning 300 LYs across. In their 1g Wingroad, they would be able travel to the edge of the local bubble and back to earth and only 22 yrs will have passed for the trio but when they return to earth they will be historical relics, true fossils as he likes calling himself. Six centuries will have passed back on earth! They definitely would be shocked and alienated by the technologies of the time.
If they decide kufa derefa kufa kamagera and venture out further to our galactic spiral arm - the Orion's Spur, for which the round trip would take 31yrs for them, this is where things get wierd( as if they aren't already!).
Remember the phasing? Outbound acceleration would take around 8yrs and would almost hit 99.999% the speed of light. But after 6 and a half to 7 years, Guka and his dirty tirries would look out the windscreen (wind?) and see a strange phenomenon. A small red dot on the centre of the windscreen.
At first, they'll think it's their eyes playing tricks on them, but then they'll realize that their Lorentz Factor at the time is 650! The leftover radiation from the Big Bang (The Cosmic Microwave Background) has now blueshifted from the microwave to visible red light. Over the course of the final year of the outbound acceleration phase, the crew will look at the spot becoming ever brighter, ever bluer until it'll reach a point they'd be staring at the eye of a cosmic rainbow. The Wingroad will have caught the gaze of the universe itself.
No more breaks. Watu wenye mliacha physics na kuchukua commerce tulieni. Stay with me.
If they decide to go to the edge of the Milky way galaxy (our galaxy) instead of just reaching the Orion Spur, the round trip would be 41yrs for the crew. Having returned back to earth from the 100,000 LYs roundi mwenda, the crew now centenarians, will return to earth having aged 100 millennia. Maybe they'd be the only humans left!
Ok, ok Guka husumbua. He decides to go to another galaxy, say Andromeda. Roundtrip 56yrs. When they come back? 5mirrion yrs. Any further venture by the crew would of course need life extension technologies. Going to the Virgo cluster, which has tens of thousands of galaxies, round trip would take
76yrs. At peak velocity of 99.9999999999999% the speed of light, the Lorentz Factor would be 250mirrions! Radiation impacting the windscreen of the Wingroad would just be too much. Need i say more?? That eye in front of the screen will explode with the same energy as the Big Bang and Guka and his babes will be in Valhalla!
So wewe @Doc oga usijaribu kutusi mzito Albert Einstein.
Lastly gentlemen, the earth is flat!
Ahsante for following to this point. It takes a very sharp mind to visualize all the above at the first read. Fellow scientists to correct errors, if any.
