NASA is examining many ways of traversing the colossal distances between the planets and stars. But what is the best method? In my opinion, you need to separate the heavy fuel from the spacecraft. Here’s the best method yet!

Hi ya there!
I'm.born buring Apollo 10 mission, i follow Space actuality since then.
I follow so many Channels about Space tech and whatever. And on all of them, you GOT only 10 worthing it, STARDUST, THE ANGRY ASTRONAUT are the two Real best Channels for me.
Angry! You should have a million AT least suscribers! WTF IS going on? There IS a problem with algorytms, maybe you are not a democrat ? I don't know, i try to understand !
I make a pray for you:
Holy IA, YT, GGL and others, NSA, TikTok: Let by the holy power of the algorythm The ANGRY ASTRONAUT break the levels of suscribers needed to be first in this domain. Thanks IA to do so. Jordan deserves full reco.
light sails are just not the way, they fail in almost every way
is this something that need dark material or something that not even exists xD
not going happen our grandkids life time. theory was mentioned. it means it based on something that think…and that think could be wrong. even einsteind could be wrong everything its just works just like flat earth theory it works bcoz its flattened globe same thing
Reminds me of a "juggler drive" concept that would toss projectiles from a base on a moon or large asteroid, catching them by the spacecraft which would toss them back, neatly reusing the same projectiles over and over. Of course there are some technical issues involved, including accuracy needed over long distances and preventing the outgoing and incoming streams colliding. This proposal partially solves that by not returning the projectiles but simply vaporizing them.
Orbit raising (NoT tO sCaLe)
No shit 😂😂😂
Photons could be viable, also is there a possibility of using neutrons in a similar fashion. Depending on which is lighter and more excitable from a lazer or mazer
With that being said would 1G create an artificial gravity well
Um, how do you aim such a telescope? You'd only be able to magnify a thin ring of the universe. And at that distance the orbital period of the telescope looking through the sun lens would be like 10,000 years so it would take that long to get that small slice of the universe. Um, in order to depend on gravity to slow you down you can't go fast getting there so, slower than the voyager probes which have solar escape velocity and won't stop and were launched with 1970s technology. Um, spend the money researching how UFOs control gravity please.
The topic is interesting but the "music" is distracting, if I want music I have Spotify.
The explanation of this possible method of propulsion given in the video is very confusing, switching between two or three possible propulsion methods as if they are all the same. The article linked to in the description is much less confusing in its presentation.
There is one point that neither the video or the article mentions. I don't know whether that is because it is not a problem or because it has been overlooked. If the pellets that are being accelerated by the laser ablation happen to acquire an electric charge as a result of the laser hitting them, they would be deflected by the magnetic fields that stretch throughout the solar system, at least disturbing the aim and possibly dispersing the pellet beam. The electrostatic repulsion between the charged pellets would also lead to dispersion.
Let me emphasize that I do not know that this method of accelerating the pellets would result in the pellets acquiring an electric charge. I merely am pointing out that it seems to me that if the pellets would acquire an electric charge, it possibly would destroy the effectiveness of this method, and so I think the possibility should have been evaluated and discussed.
Can this method be adapted to propel spacecraft to orbit? Of course limited by lack of a vacuum. Perhaps small micro particles accelerated to impact spacecraft plate to transfer momentum
Is there a link to a paper about this concept?
My first thought was that we would use a Pellet Gun to shoot in Outerspace.?? Then I thought maybe someone is working on a pellet-sized fuel, to do what, drive down the street.?? Photon Pellets are used in Space to push a Spaceship like a Light Sail being pushed by the Sun that hopefully will get us there faster than a Light Sail I’m guessing.
One question, if a spaceship can be pushed by a laser then why couldn’t we use lasers of some kind as fuel? I mean lasers are moving at light speed, so with a laser at the tail end of a spaceship pushing against space? No being dragged behind the spaceship by a fishing line and blasting it…the reflective plate or why not use the laser to heat the fuel? A laser has to be lighter than the engine that heats the fuel to make the propellant hot enough to propel the spaceship. No that won’t work, you’ll need too many solar panels to heat the laser.??
Use a magnifying glass to magnify the Sun's rays to heat the propellant, just a thought…
Man, this guy is Angry!!!!!!!!!!!!😂
I imagine space dust would make a mess out of a solar sail.
Black hole warp drive works better
Like a carrot on a stick riding a donkey. The black hole is in front pulling you in but you never get to the center it moves with you
how far away can these "mass beams" be detected?
would this give away information to other civilizations that may or may not be in this galaxy (think Schrodinger's civilization(s)), if they are watching in this direction? and the beam's "noise" travels in their direction?
letting them know that not only is there microbial life in our star system, which they already knew, but also "intelligent" life?
are there off-the-shelf industrial lasers that can be used for propulsion?
While listening, Can’t help but think of the cone shape that’s gets etched into old CRT Radar screens from particles getting carried along with the Electronbeam because of poor gas evacuation. So I take it you’re not concerned about abrasion, or other things that would act like deflection coils on an old CRT, so many to choose from gravity from different sources, solar winds, Solar flares etc.
Have you looked at Mach effects drive yet?
Would this not leave a bunch of space junk behind it?
great vid !!!
The Plasma Magnet(ic) Sail would provide velocities of ~ 400 km/sec in the ecliptic and ~ 800 km/sec at 25° above or below the ecliptic. Additionally, once outside if the heliosphere the PM Sail can slow down to relative station keeping (a standstill). Kevin Hambsch
The solution seems simple if less efficient. Just cut the fuel in half and have the fuel for the return journey only.
To my admittedly feeble intellect, this approach seems akin to running an EV on the power produced by an alternator driven by the drive train or propelling a sailboat with the wind produced by an onboard fan powered by a microturbine turned by the boat's velocity through the water. The only energy advantage I can glean from your description is that a particle beam would diffuse far less over distance. Otherwise, the photons should be no more efficient at propelling ions than at propelling a solar sail. There should be no gain in energy. One doubt I have is whether the particle stream could be tightly coherent after being blasted by a laser beam that is already beginning to spread out. Wouldn't the angle of dispersion be carried over into the particle stream?
Mars in 10 days….have you worked out how many G's this would produce?
I'm still half asleep… he said 9 times faster than voyager and I actaully said out loud…"warp 90? oh he meant the real voyager" lol
Math does not add up.
Why would a small particle be able to use orders of magnitude more energy from the same laser than the solar sail?
It is the same solar sail area. The particles will either be oriented to that sail or not. They wont gather energy outside of the sail section and then change their trajectory to hit the sail.
I call BS.
OMG will you please stop begging for money. You're worse than the guy outside of the liquor store
