    Theoretical astrophysics and the theory of relativity are no longer a theories!! When did this happen!! So excited.

        I don't know why everyone so excited to meet alienshistory tells us that would have technically advanced group of people come to primitive group of people it doesn't end up well for the primitive group of people Independence day was just a movie Will Smith ain't going to be able to save us he's just an actor and actually the hero of that movie is some paranoid Quaker who lives in a trailer that's definitely not going to be how it goes down if aliens show up

          what if it was trying to take a quantum picture something of us so it could like create a similar stimulation to run out all outcomes of some war it plans to have with usmaybe the reason there's no exhaust detected in the recent slingshot it around the sun even though it's an interstellar space ship capable of faster-than-light travel is because it wanted to appearnot to be a spacecraft and so it dropped out of warp it just use the Sun's gravity and then the slingshot effect exit the solar system after having already taken that 3D picture and then when it reached escape velocity it turned on its FTL engine

            If I'm not mistaken once one of our spacecraft reach velocity they shut off their engines and carry on a planned course, only maneuvering to ensure they maintain the proper trajectory. If you were going to pick a solar body to perform a gravity based maneuver around wouldn't it be the most massive object in our solar system? In all seriousness this is 99.99% a pile of rocks, and of course because the sun is the most massive thing in our solar system it would be the thing to draw interstellar objects in and effect their trajectories. Very exciting even so.

              Sure ...would you like to go in a spaceship??... here's how...Love one another our souls came from the same sun that sits in the middle of the universe wich is our Father his name is LOVE no lies, sarcasm,wars,no resentment,hate, no C R I T I C I S M,no drugs,no alcohol, No more killing and eating innocent beings (animals)Our brothers are saying that a planet without animals wouldn't survive,we can't go inside of the spaceships with our contaminated bodies.Once you accept and follow all this knowledge from the bottom of your heart, you will go in,then you will be coming back to planet earth to deliver a message from our Father to humanity;this is the message.... RESPECT LIFE THE WAY OUR FATHER HAS CREATED IT.We are only months away from see them in the sky there's going to be trillions of them.Ohhhh yes the ones that I'm referring as "they" or "them" we call the:Angels, archangels, cherubs, gods, messengers,now we call them... aliens.The don't have wings they have spaceships, they don't play trumpets the spaceships are making the noises "like" trumpets Google"The Hum"Our teacher Jesus Christ is back with his army of light....let's welcome them.

                            I'm not even sure why they find this funny, but it's definitely elongated. And it's definitely not a UFO, it's just a very interesting, weird and an elongated Rock, or should I say asteroid.

                                                ...despite it is a fact proven countless times that Jesus as a person surely existed and was crucified (like many others in that era). The only question is whether he was the "son of God" as the religious believe, or a regular person like any other.
                                                BTW it's 'interesting' that I don't see you openly disbelieving Mohammed or Moses or Buddha or any other religious figure, it's only Jesus of Christians who is the target. Isn't that fascinating?
                                                Get your facts straight before being smug.

                                                    A spaceship can exploit the gravity to take it where it wants to go. Just start the engines at a precisely calculated time, let them burn for a precisely calculated period while pointing in a precisely calculated direction, and the gravity will do the rest.
                                                    When sending space probes to other planets, they can coast unpowered for months or even years after the launch from Earth, only guided by the gravity of the Sun and the planets.

                                                    Yes that was smart reasoning, I'll give him that. But if you have a ship in space, you're not interested in it drifting as gravity wants, you're interested in driving it to where you want to go. So Tyson's argument is still more realistic.

                                                    He actually made a good point.
                                                    The Apollo spaceships were mostly controlled by gravity alone on their way too the Moon and back, as the engine burns that changed their speed and trajectory only lasted a few minutes at the time.

                                                        if you stop to think about it, a rock would make the perfect space ship. if its made out of iron, it wouldn't need any kind of shielding from space debris. just hollow out add engines and controls and fly away, but an asteroid would be a perfect stealth space craft.
