When it comes to space, there's a problem with our human drive to go all the places and see all the things. A big problem. It's, well, space. It's way too big. Even travelling at the maximum speed the Universe allows, it would take us years to reach our nearest neighbouring star.

But another human drive is finding solutions to big problems. And that's what NASA engineer David Burns has been doing in his spare time. He's produced an engine concept that, he says, could theoretically accelerate to 99 percent of the speed of light - all without using propellant.

Can you believe 93.016 billion light years in a single picture ! Entire observable universe in one image with a math trick, musician Pablo Carlos Budassi managed to do it by combining logarithmic maps of the universe from Princeton and images from NASA ! .
In this map, our sun and solar system are seen in the middle, followed by the Milky Way Galaxy, another ring of nearby galaxies like Andromeda, all the way out to cosmic radiation and plasma generated by the big bang on the furthest outskirts of the image ! .
