The Eiffel Tower can be 15 cm taller during the summer, due to thermal expansion meaning the iron heats up, the particles gain kinetic energy and take up more space.
100 Mind-Blowing Expansion Facts
The Eiffel Tower gets taller in the summer. When the iron heats up, the tower can be up to 15 centimetres (6 inches) taller due to thermal expansion.
In the summer, the Eiffel Tower gets taller. As it is made out of iron, due to thermal expansion the Eiffel Tower can rise to 6 inches taller.
There are stars we will never be able to see. Ever since the Big Bang, most objects in space have been moving away from one another. The expansion of the Universe is accelerating. This is one of the facts about space that has rocked the cosmological boat over the past few years. As regions of space are whizzing away from one another at an ever-increasing rate, the first population of stars to form in the Universe are now too far away for us to ever hope of spying on them – even using the best present or future telescope. Hope is not lost; we can attempt to spot them indirectly via the energetic bursts of radiation they emit at the end of their lives.
