6. Scientists have three different theories:
• They believe the smallest black holes
formed at the conception of the
universe. The size of the supermassive
black hole is related to the size and mass
of the galaxy it is in.
• The largest black holes are called
supermassive black holes. They were,
scientists believe, formed at the same
time as the galaxy they are in, soon after
the Big Bang.
7. • The other theory is: when the
centre of a particularly big star
collapses, stellar black holes are
created. This causes a supernova,
which is when an exploding star
blasts parts of itself into space.

9. You might expect to get crushed, or maybe
turn to pieces. But the reality is stranger
than that.
A black hole is a place where the laws of
physics as we know them break down.
Einstein taught us that gravity warps space
itself, causing it to curve.
10. The instant you entered the black hole,
reality would split in two:
• In one, you would be instantly
incinerated.
• And in the other you would plunge on
into the black hole utterly unharmed.
