  • The strongest evidence for the Big Bang hypothesis is the existence of the microwave background radiation (the temerature everywhere in space is about 3 degrees above absolute zero).   This is thought to be the "echo" of the Big Bang, all that remains of the original fireball

  • The so-called Big Bang theory is the current favoured hypothesis of the formation of the universe according to astronomy.  This asserts that some 12-15 billion years ago there was a suddenly expansion and explosion of all matter and energy out of an original point - out of literally nothing

    The so-called Big Bang theory is the current favoured hypothesis of the formation of the universe according to astronomy.  This asserts that some 12-15 billion years ago there was a suddenly expansion and explosion of all matter and energy out of an original point - out of literally nothing - and that not only space but even time began at this moment.  (So we cannot speak of an explosion in space - because there was no space before, or no time at which this could be measured - space and time being properties of the universe rather than something outside of it).

  • According to quantum  theory, matter and antimatter particles are created in pairs all the time  out of nothing (i.e. vacuum) and cancel each other out with no effect on the  universe.  They are therefore called virtual particles).  At  the Big Bang, however, massive amounts of matter and antimatter were created and  although much of it was similarly cancelled out with a huge release of energy,  matter won the day and spawned the universe as we know it.
