A Journey to the End of the Universe

6 403 603 दृश्य

Could humans ever travel to other galaxies within their lifetime? The immense scale of the Universe seems to prohibit such voyages, after all the nearest galaxy is so far away that it takes light itself - the fastest thing in the Universe - 2.5 million years to complete the trip. Remarkably, there is a trick that might allow humans to accomplish this feat - join us today as we step onboard the constantly accelerating spaceship!

  • Guys, I've made an album inspired by your work. Halo Drive concept is so cool and futuristic that I called my last EP Halo Drive. I think you, Mr. Kipping and your team are dancing sometimes, so enjoy! indive.bandcamp.com/album/halo-drive P.S. support with likes, guys, so Cool World team see it! Thanks!

  • The point you were making about 100 millennials for humans to come back here. So that means another species perhaps completely different than humans that they have inhabited the earth first could be on that very same objective and could have left around 100 millennial's ago and could return it any moment? Where we've actually went through an extinction and have regressed as far as technology according to their society. That could very well possibly be a scenario correct?

  • Okay, rather depressing, but maybe we have our alternative universes to pop through to. Or maybe our science is more primitive than we give it credit for, and there are other surprises along the way. Remember, we are only 300 years beyond the industrial revolution, when Newtonians thought we had it all sown up, and then came quantum physics. Socrates said knowledge is only a model, or stepping stones to build more knowledge. What next?

  • There's a much bigger picture forming than just 'us' ... We basically are a speck in the scheme of things, a mere wisp of breath, a blip, we are only significant in our own world, which itself is but a tiny drop in a incomprehensibly huge ocean... Not only is their life out there, they are so far away they will never know if our existence, and the same will go for them with other life, and so it will go on..... We are but a single heart beat, a faint miniscule blip on a radar....our entire existence is no more than a single beat of a pulse. So live life....stop wasting it. Everything you do, no matter how great here, means zilch in the scheme if things... We are but dust. Right, pizza and a beer, playstation and a bucket of ice cream it is then. :-)

  • The process of planning, designing, executing and maintenance of universe functioning systems is referred to as “Universal time limit operation system”. This process is carried out by the Almighty of the Universe based on the Nature of Reality of the Active Planets. These systems serve a variety of time limit functional needs of planets and living beings. Several factors in time limit functions need to be considered based on the functional behavior of non living things when activated and living things. All elements of non-living things in the Universe are having two functional behavior of minus and plus and require activation to perform its time limit function. Every element in the seven universes is made of Jabiga atoms (living electro molecule and living nucleus dust) and Ronos (electromagnetic force). All atoms of an element are not the same but all the atoms have minus and plus sense. Atoms of different elements are having different kinds of behavior and have different kinds of time limit functions. Jabiga atoms of different elements which are normally related to each other can join hands when time limit activation is normal to form a new force or to create a new component. If not related to each other it takes avatar as a destructive force with abnormal time limit creates natural calamities which could not be controlled by human. There are two fundamental forces namely Jabiga and Ronos forces with four avatars. Jabiga forces with plus and minus characters and Ronos forces with plus and minus characters are involved in keeping stable Jabiga atoms. Ronos electromagnetic force helps for keeping Jabiga atoms stable. Another fundamental gravity force disturbs the time limit function of Jabiga atom to some extent. Earthians View: According to study by Earthians ‘When solar system was born 4-6 billion years ago only 6 percentage of potentially inhabitable planets that will ever form in the universe existed, which means 92 percent of more earth like world yet to be born.” Earthians accepted that Earth planet is not flat but just like a ball rotating, that there is a vast dark force, Earthians studied about the shining stars and heavenly bodies and also named some planets and stars. Earthians creating horoscope and calculating the fate of human being based on the planetary movements and stars. Earthian accepts that there are seven human beings with similar face structure. Earthians cannot deny that they appeared on the Earth without parental sexual functions. There is Universal power that no one can see or feel the power or predict the time limit function of the Almighty. • There are about 300 Active planets in seven universes. Just like Earth Planet there are one planet in Haloma Universe, one planet in Rajsival Universe and one planet in Hindoma Universe. All the three planets are identical to the Earth Planet, and Bindra (mold) is just like Earthians, but mass of the three planets may vary. • The Almighty of the Universe for administrative convenience has divided the entire Universe into seven universes as detailed below to enable them to act independently with the blessings of the Almighty. o HALOMIA o AVILIAN o RAJSIVL o OHMALIK o RAVOLAN o ABILANA o HINDOMA The Almighty is the creator of every thing in the Universes and creator of Central force, Central Source and Dark force for better living of all beings. The Almighty is fixing time limit functions to all living things and non living things.

  • this is because we truly live in God"s head(brain) = universe (a net of neurons). and we humans are the basic/smallest particle in existence and most important because we are created in the image of God. So, as above so below, as in macro so in micro, as it is outside so it is inside, or when you see mandala and zoom in you see the same structure repeating itself at a certain distance when zooming in or out..Universe/Creation/God is one being that we witness as a child growing to adult hood and afterwards aging and dying, just like we do, in conclusion universe/god is outside us as well as inside us ! we are indeed made of star dust :)) and faster than the speed of light is a thought !

The point of cryofreezing while in space would defeat the whole purpose of exploration - after leaving Neptune ( about 12-15 ) years you would want to be able to visualize what is beyond our universe. We are no where near the technology to be able to hibernate for that period of time much less beyond that.

  • Now, say you have infinite fuel for the ship, and a crew of immortals so that you could just keep accelerating at a constant rate for all eternity. If there is some kind of endpoint where space and time break down and the very fabric universe itself dies away, you would eventually hit that point. Supposing of course that you reach that point before so much time has passed even in your frame of reference that your protons have decayed. Although, at this point, what you're effectively doing is simulating the effect of falling into a black hole in ultra-slow motion. Hell, I suppose it could also be true that your constant acceleration engine will be trying to output so much energy that it will have become a kugelblitz and collapsed into a black hole, killing the whole crew, long before this point, but you would experience the same effect, just a lot faster. That black hole would then be flying through the universe at such a high Lorentz factor that its time would be so dilated that it would likely be the last thing ever to exist in the universe before it finally decays due to Hawking radiation. If we sent an object out like this to just continue to accelerate until it eventually became a kugelblitz somehow, then we could probably exponentially delay the heat death of the universe. At least, from our frame of reference. I mean, the universe would exist in a state where it would just be this one black hole moving at a crazy high percentage of the speed of light for an unthinkable amount of time with absolutely nothing else in the void, but hey, as long as that black hole is there, the universe hasn't technically experienced heat death yet.

  • There was a clip in this video showing horses and riders trying to catch a train. I think it is from an old movie I have been trying to remember the title of so i can watch it again. If you know the title of the movie the clip is from please let me know.
