I've always wanted to build a real rocket that could go to space, but it's far outside of my peasant like budget. So I've thought of what seems like a good idea for a cheap solution to launch vehicles to space.Use a balloon to lift a small stabilized platform that has a rocket on it. The rocket launches from there into orbit. And when I use the word platform I don't literally mean a flat launch pad but something that sort of looks like a missile launcher...idk what the technical term for that is...turret?You could also scale this idea up for conceivably larger loads. One problem I can see though is when the balloon goes up it would drifts away from the launch site and possibly fuck up your launch. 10 posts and 1 images omitted.

As well as what dark energy really is; and POSSIBLY has something to do with where gravity is permeating into our universe from, since it is weaker than it should be compared to the other forces, even though that really wasn't intended to be included with the rest of the theories. I could be totally wrong on all accounts, but I do love the ideas.Here we go! (Keep in mind that we don't know what the inside of a black hole is like, certainly not a 4D black hole.. the 'polar ends' talked about here could give off gravity due to strange possibilities, like space within space... the 4D black hole that is theorized here to give us our 'spacial plane' could also be sitting inside a spacial plane itself, and it's so large that it reaches the maximum edge of its bending - on the outside of the 4D black hole)BUT ANYWAY AGAIN, here we go.Outside of our universe it is theorized that energy is being formed and popping out of existence continuously, at the planck scale. It's theorized this is where our quantum singularity came from. Through quantum tunneling, that tiniest of energy became the singularity that eventually birthed our universe. The problem is we don't know why it expanded in the first place, or why there was more matter than anti-matter as for us to have enough matter, a significant enough amount, as to form galaxies and the universe we know. They believe there are infinite universes, or a multiverse, with every possibility of physics realized. But I'm only concerned with our own, and the answers to these questions. Continue to read and you might agree that it is much easier for our exact universe to continuously be recreated with the exact same amount of matter as this one; which would be highly significant if true because that means the physics that produce life would also be eternally renewed, and without much time needed for it to happen in comparison to random universes. And what a pleasant thought that is.It is my theory that not only does energy at the planck scale pop in and out of existence, but also multiple singularities constantly coming into existence as well. Keep in mind we don't have, what I call, a spacial plane yet. The singularity must first give birth to that plane. But why does it expand and how does it create that spacial plane? We go back to the multiple singularities. For some reason, there are more created of regular matter than anti-matter. First off though it takes a long time for a singularity to come across another singularity, and with no spacial plane yet there would be no gravity to bend it and draw them towards one another for these collisions. But after enough time, there was a singularity of enough matter that came to being through collisions with singularities of likewise regular matter. Eventually it collided with a singularity of significant amounts of anti-matter so that the energy released from them both did something amazing. The anti-matter destroyed as much matter as was its own equivalent, but from the force of it all an unimaginably large black hole was formed and it sucked all the leftover matter back into itself, with none escaping. This is the theorized 4D black hole, published by another scientist; although I'd had the theory months before him - that there was an original black hole that were reside inside. But being 4D adds much significance to my original theory, so I thank him for that. Moving on. The matter sucked into this 4D black hole was smeared across the surface of its inside. So our universe is a 3D plane inside a 4D object, and it is this 4D black hole that is our 'spacial plane' on which matter can bend the plane with its mass, giving our universe the properties we see today. Like a black hole in our universe shooting gamma ray bursts from two opposite ends instead of all directions, so does this 4D black hole similarly have 'polar ends'. While the first singularities were ultra dense, this point in the 4D black hole is even denser. With so much energy and force released from that first collision of opposite singularities, the leftover matter sucked in expanded out instead of staying a singularity at the 'polar end' of the 4D black hole. The matter was thus able to escape its point of origin of the first polar end, and made it far enough that the opposite polar end of the black hole began to pull us towar… Comment too long.

If humans are going to build a city on the moon this century it should definitely be done in 2069, if they do it in 2068 or 2070 instead it will go to waste.It'll go down as a historical fact until the end of time that the City/Colony was founded in 2069.

What I'm not so sure on is our penchant for clinging to imagined borders.What is it going to take to break free from that? I could see Mars ending up being its own nationality so to speak. From a governance stand point I can see the practicallity, each planet will mostly be responsible for running it self. The alternative or events leading to that style would be akin to the Roman empire becoming too big to manage.So yeah, general ideas, hopes, anticipation for how things will be.

The only downside is that it doesn't really lock in place. Besides refractors and newtonians, there are catadioptric cassegrains.

Inb4 telling me to post this on /vg/. It's a simulator not a video game. It's serious bzns and no fun is allowed. Besides I've posted it there before and no one there is cool enough to go to be interested in it.Any one here ever try this out? I got pretty into it a while back. I've used various Delta glider models to launch from cape Canaveral, dock at the iss and then land on the moon at the fictional moon base. I've even made the trip home, but I can't re enter the atmosphere with out computer assistance. I either explode or bounce off the atmosphere every time.I cant get my head around planning interplanetary trips. The MFD is too obtuse of a tool for me to plan that sort of trip. I wish there was kerbal maneuver node mod that let me visualize the trajectory vissualy with a 3d image rather than a 2d circle on a plane and some numbers.I haven't tried it in a while and my gaming pc is dead, my lap top wont handle it.

So mgcos(theta) = mv^2/R ... too distracted to finish the rest but solve for the max v that the inward radial component can still provide a = v^2/R, then you can solve for the value of cos(theta)

This has certainly been asked here before but please help me understand this.A space ship travels around earth near lightspeed. I understand that velocity makes time aboard the ship seem slower to a spectator on earth. And when the ship stopped moving the crew would have aged less then this spectator. But here's what i dont get. Why does the spectators time also seem to move slower to the crew on the ship? Wouldnt earth look like someone pressed fast forward? But lets say earth time seems to move slower, what happens when the ship slows down, does light from everything that happened come towards it like a flash?I know i sound dumb, but that's okay. 2 posts omitted.

In special relativity, there is no preferred reference frame. If a rocket ship is travelling past the Earth, from the rockets perspective, the Earth is travelling past the rocket. So each will see the other's clocks as ticking slower to their own. This symmetry only holds for inertial reference frames though (no acceleration or deceleration). In your example, the space ship is constantly accelerating to move in a circle, and this destroys the symmetry. A more illustrative example is the one of the twin paradox. In the twin paradox, the ship leaves Earth and travels near the speed of light for a while and then turns around and returns to Earth. One twin is stays behind on Earth, and the other travels on the ship. The one who stayed behind on Earth has aged more than the voyager twin. It's a seeming paradox, because each twin witnesses the same thing: the other twin flies off at breakneck speed and returns at the same speed. The difference is that the space ship twin feels an acceleration. It's this acceleration that causes the jump in time - known as gravitational time dilation. This is an aspect of general relativity - beyond the scope of special relativity. So yeah, as soon as the ship starts accelerating or decelerating (as in your example), the events on Earth will play out in fast-forward from the ship's perspective.https://en.wikipedia.org/wiki/Twin_paradoxhttps://en.wikipedia.org/wiki/Gravitational_time_dilation >> Grote Reuber - Mon, 03 Aug 2015 08:00:44 EST Du35j2Lj No.55580 Reply >>55579Thanks you!
