A Journey to the End of the Universe

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!

    Then we should know that's there is no end to our solar system. delete that questions out of our life let's think about live in communicate together and not think about far away because there is no end of far away .spending a trillion dollar for no reason .for sure that is someone out there they have more technology than us. Today I learned something that's you have to take care of your family the family you born inside you grow you went to school to college to be more knowledge than ever spent your knowledge right here Earth it's our first and end of our life.. I created this example out of my mind. when you cut Apple from the tree feed people around you instead of grab that apple and throw it as far you can't in it will smash thousand piece that's no one can get even one piece of that the power you get spread that power around you . I really think this person he explained something amazing to all of us you are very amazing I really thank you .you put all this information together to help stupid human to understand there is no end to our solar system. NASA China Russia spending trillion trillion of dollar for no reason at all another example out of my mind... if I win inside the cave to grab a piece of gold and come out I'll go again because that piece it will help people around me but if I go and I can't see except dirt and too many planet there is no reason to go back a human is very dumm....

    I had this nightmare (I guess I would call it since it was pretty terrifying, rather than a normal dream) where I was in a spaceship traveling so far that I was going past all the galaxies to the edge of the universe, and once I hit the edge of the universe, my perspective started to glitch out and all the lights in the spaceship turned off, my eyes and everything around me started to start glitching and it all started to fade away, then my view turned to black and then I jolted up from my bed. That was my take on that, it was quite terrifying, honestly.
