with our current scientific and technological progress, I can say yes we can manage to send such a spacecraft to Proximal Centauri b in the next few decades. But if we found this planet habitable, Which I exclude because this requires several conditions similar to those on earth, how can people with such mass go there? I think this will take several decades if not less than several centuries to acheave this goal.
I think travelling at light speed is impossible for human being.
Have you ever heard about teleportation ?
Anyone of you have ever heard about Philadelphia Experiment ?
yes you are right @souada. In my view, a physical body like that of a human being can not move at the speed of light. Unless we talk about teleportation. in this case, we enter the field of parapsychology and science fiction.
Hi @hasmez and @souada
It is possible for a human being to accelerate to light speed without any severe consequences, even with a moderate acceleration of 1G (9,8 m/s) a traveler will reach close to lightspeed in approximately 350 days. (remember, 1g will feel like standing on mother earth) ;)
The tricky part is that you will have to carry with you energy in some form to propel your craft, and the amount of energy needed will be enormous. That's why the suggested craft in the article above weighs in at about 1 gram. @erlendgroseth
For @onebitnews
In My head It’s simple enough. If someone can dream it, someday someone will make it. Everything that has been invented in the world has always been made after a dream or a fantasy. So yes this will be a part of the puzzle on how we can do this in the future. It might not be the sail that solves this, but some kind of material and some smart persons will find the right technologies we need. It will be like Mr. Musk just proves everything is possible you just have to want it enough. And yes there are people wanting to make this come true. The proximity to get enough energy will be solved during the next few years I gues. The development on this area is going incredibly fast and will not slow down for many years.

Hi @everydaycoach
"If someone can dream it, someday someone will make it." - That is true, and there is a good side and a bad side to that statement. On the good side you have people like Columbus, Galileo Galilei and Carl Sagan but great minds can also set us back, like R. Oppenheimer.
Sails is definitely not the answer to our dreams of conquering space, but it can be a cheap quick-start. @erlendgroseth

Jeg var også glad i Walt Disney, mannen som har laget fantasi for oss alle i oppveksten.
Helt til den dagen jeg fant ut at Walt Disney var en frimurer, og har laget NASA til sin fantasi produksjon.
Space might be the final frontier, but its made in a hollywood basement
Ser den, men har ikke alle store tenkere og personligheter i USA vært eller er medlem av slike samlinger. Alt fra Einstein, W. Shakespeare, B. Blinton, B. Obama osv. Om de er frimurere eller medlem av "klubber" som består av samfunnstopper og unike mennesker med spesielle egenskaper. Slik har det nok vært i de fleste år og kommer nok alltid til å være. Om det er rett eller galt skal jeg ikke uttale meg om. Men at det finnes slike grupperinger med mennesker og at det gjerne er de ekstremt kjente unike menneskene som er medlemmer i slike er etter hva jeg har lest meg frem til, helt normalt:-)👍
That is very interesting, I would assume the laser is powering a solar sail?
I wonder if it would have the same problem you talked about last week with the Tesla car. Would radiation be a problem or could they use it somehow to power the sail? I sure hope I'll be around at least long enough to see things that happen in the next 25 years!
Hi @tbnfl4sun
That's a good question!
The radiation some scientists claim will decay Musk's car is high energy particles from our sun. The radiation level drops of quite quickly when you move away from the sun. (decreases by a power of four over distance). So for most of it's journey it will be safe. @erlendgroseth
For @Onebitnews
Me too @tbnfl4sun I really hope I'll be there to see the discoveries in the next 25 years, when we'll be there we'll always hope to stay alive the next 25 years to attend the other discoveries lool, I think it's is not reachable but it is good to have always hope to live and attend good things that happen thanks to technology.
No conspiracy in this issue?
Oh well, I will have to give you some conspiracy stuff to think about then.
Don't get your hopes up for space travel anytime soon.
think about this for a minute:
Same stuff different creator:
So, how small would that make Proxima Centauri from our perspective? and we can still see it in the nightsky?
Hi @deeprabbithole
Wow, you amaze me. It is intellectually challenging to deny absolutely all common sense.
I think you got a bit too deep into your rabbithole on this one.

To know that it exists is great. But from there to move in, better not to count on it right away.
The discovery of Proxima B, the planet closest to the Earth outside those of the solar system, is certainly encouraging.
To travel the forty thousand billion kilometers that separate us from Proxima B, it is estimated, Michael Gillon, 50,000 years aboard a space shuttle equipped with current technology. Even at the speed of a space probe like Helios, the fastest object ever built by man (70 km / s), it would take another 18,000 years. The only reasonable hope for the astrophysicist: "Mastering nuclear fusion", a technology that would reach 30,000 km / s and approach Proxima B in forty years.
Du skal få meg til å tro mye, men en 4x4m alufolie som reiser i umennesklige hastigheter? uten å gå i stykker? Ikke sjangs i havet! Alufolien hadde vert en krøllball lenge før den kom opp i 100km/t.
Albert Einstein's theory of the speed of light, which has believed in humanity since its appearance in 1905 was not correct, was reversed. Researchers have found that the real speed of light is much lower than the miracle speed that we believe for more than a hundred years.
According to Einstein's theory, the speed of light in the vacuum is 186282 miles per second (about 300,000 kilometers per second), but the new study found that Einstein was wrong, and that this speed is exaggerated, because the real speed of light is less
Hi @agdali
Thanks for your comment.
It was not Albert Einstein who calculated the speed of light, but a Danish astronomer called Ole Røhmer back in 1642 by measuring the the time it took for one of Jupiter's moons (Io) to appear from the backside of Jupiter. The time of the occultation wearies by the distance between Earth and Jupiter.
More on that topic here: https://en.wikipedia.org/wiki/R%C3%B8mer%27s_determination_of_the_speed_of_light

Tror det vil bli en kombinasjon av flere typer fremdrift. Kanskje solseil og så over til en motor som tar over etter en stund. Vi trenger uansett en motor for å bremse/ styre fartøyet.
Får vi se en slik ferd, eller starten på en slik ferd i vår levetid?
So close, and yet so far. On a galactic scale, 4.25 light-years, this represents a jump from a chip. At the level of our current technologies, it is an almost impassable ocean. The discovery of a potentially habitable planet, in orbit around Proxima Centaurus makes dream all astronomers. But before you can get there, or even send a probe, it will take major technological advances.
The Philadelphia Experiment is an alleged military experiment supposed to have been carried out by the U.S. Navy at the Philadelphia Naval Shipyard in Philadelphia, Pennsylvania, sometime around October 28, 1943. The U.S. Navy destroyer escort USS Eldridge (DE-173) was claimed to have been rendered invisible (or "cloaked") to enemy devices.
The story first appeared in 1955, in letters of unknown origin sent to a writer and astronomer, Morris K. Jessup. It is widely understood to be a hoax; the U.S. Navy maintains that no such experiment was ever conducted, that the details of the story contradict well-established facts about USS Eldridge, and that the alleged claims do not conform to known physical laws.
Nikola Tesla : "My brain is only a receiver, in the Universe there is a core from which We obtain knowledge, strength and inspiration. I have not penetrated into the secrets of this core, but i know it exists.
Just before his death, Nikola Tesla was working with another genius, Albert Einstein on a project for the United States Navy at the Philadelphia Naval Yard where they were trying to create an electromagnetically charged invisibility cloak for the USS Eldridge. The experiment was allegedly based on an aspect of the unified field theory, a term coined by Albert Einstein. The Unified Field Theory aims to describe mathematically and physically the interrelated nature of the forces that comprise electromagnetic radiation and gravity, although, to date, no single theory has successfully expressed these relationships in viable mathematical or physical terms.
All records of the tragedy have been kept secret, but there was a rumour linking the experiment with the great inventor Nikola Tesla, who supposedly made all the necessary calculations and drawings and provided generators that were used for the teleportation of the Eldridge.
Tesla wanted a type of "Zero Point" wristband for the sailors on board the Eldridge to ground them during the Experiment. Without the wristbands, they could be floating; lost in space and time or in total disorientation. The government did not want to spend extra money on the wristbands. Tesla left.
After Tesla left the Project, Dr. John von Neumann took over. [John von Neumann was a Hungarian-born American pure and applied mathematician. He made major contributions in fields of mathematics, functional analysis, physics, quantum mechanics, economics (game theory), computer sciences, self-replicating machines, and statistics. He was a principal member of the Manhattan Project].
Tesla had not lived to witness the disaster, and shortly after his death, the FBI confiscated his entire archive. More rumours circulated which indicated that the scientist’s death was no accident and that he had been warned of the danger in arguing with Einstein, ordered to desist from experiments on human beings and, finally, forced to silence.
Hello OBN.
Yes @aminekad. solar energy is abundant, an ideal alternative to any kind of fuel and does not cost anything. In addition to that it is clean.
The problem is that the technology available nowadays does not exploit not even 15% of it.
I am very happy to have this opportunity.
this is gold for me
i have one idea about
sbd.
I think it would be great if sbd can be directly sent to the account directly
without having to channel to btc or any other type of digital currency.
this is the idea
hopefully acceptable
thank you @onebitnews
It is often mentioned that the Earth is 12,750 kilometers in diameter, that the Moon is 385,000 kilometers from us, that the Sun, which measures 1.4 million kilometers, is 150 million kilometers away from us, than Pluto, the most distant planet is 6 billion kilometers from here, while the nearest star is 4.3 light-years away and the Universe (as it is conceived) extends over fifteen billions of light-years on both sides of us .
The speed of light (299,792,458 m / s) was measured in the seventeenth century by the Danish astronomer Ole Christensen Rømer, who observed in 1576 a delay of fifteen minutes in the predicted occultation of Io, a satellite of Jupiter attributed it to the change in the delay of transmission (due to the change in the relative distances between the Earth and Jupiter).
The speed of light was then estimated at 200,000 kilometers per second, about 35% below its true value because of the uncertainties of the time on the size of the Earth's orbit. This result will fascinate Voltaire later, who will speak in his works.
Rømer thus invalidated a result of Galileo who, experimenting with a helper with a lantern, had believed that light was transmitted instantaneously.
According to theories of modern physics, and especially Maxwell's equations, visible light and all electromagnetic waves have a constant velocity in the void, the speed of light.
It is therefore considered as a physical constant noted c (Latin celeritas, "speed"). But it is not only constant (we think) in all places (and at all ages) of the universe (cosmological principles weak and strong, respectively); it is also from one inertial reference point to another (principle of restricted equivalence). In other words: whatever observer's reference inertial reference or the speed of the object emitting light, any observer will obtain the same measurement.
No material object or signal can travel faster than c within the framework of existing theories. Only virtual fronts can be "traveled" faster than c (at so-called supraluminum speed) (the shadow extended at great distance from a rotating object, for example), and we can not, of course, use it to transmit a signal, nor energy. They are not even really objects.
The experience of Alain Aspect shows that an observer can be informed instantly, by a measurement on a nearby particle, of the state of a distant particle, but there is no real signal transmission either. .
The speed of light in a vacuum is noted c:
c = 299 792 458 meters per second
This value is "exact" by definition. Indeed, since 1983, the meter is defined from the speed of light in the vacuum in the international system of units (link), as being the length of the path traveled in the vacuum by the light during a period of 1 / 299792458 second. This means that the meter is now defined by the second, via the speed set for the light.
