    A black hole is a cosmic abyss with gravity of such intensity that nothing, not even light, escapes it. Now, for the first time, a team of astronomers has released an image of the space anomaly, which is created when a star collapses. Professor Brian Greene of Columbia University and the World Science Festival provides context and talks to Judy Woodruff about this scientific breakthrough.

    Best not tell Sheldon Cooper, he might throw a major wobbly.
    Logically: we have made copied nature to create fusion and fission bombs and nature seems to be telling us there is a far greater natural source of energy that presumably one day will not be able to contain itself and result in a galaxy-forming explosion ( Big Bang style).

    whilst we can create a fusion bomb, we cannot to date control fusion for more than a couple of seconds, however galaxies are not formed in a 'big bang' style explosion, rather they form and evolve over billions of years as stars group together etc. Gravity is the driving force behind galaxy formation.
