• Question: If a bang is created when an object goes faster than the speed of sound, what will happen if an object goes faster than the speed of light ?

      That is a great question, Priscilla04 šŸ˜Ž Firstly, to get something to travel at the speed of light we would need an INFINITE amount of energy šŸ”‹ – as objects travel faster they get heavier and heavier – and the heavier they get the harder it is for them to reach the speed of light šŸ’«āœØ BUT that’s no fun so let’s look at what would happen if you DID manage to get close to the speed of light… šŸ¤” The object or person would experience a slowing of time (!!!) – time would move slower than it would for someone staying still ā°šŸ˜³ Also, what they would see would change – things would appear to come towards them as if through a tunnel-shaped window āœ³ļøšŸ‘€ Pretty mind-blowing… What else do you think might happen?

      Great question! It really made me think šŸ¤”
      But exactly as Sammie says, as objects move faster their weight gets heavier and heavier until they get up to a super speed and their mass is too heavy and therefore the energy required to move it is too great. So for now, nothing could move faster than the speed of šŸ’” which is 299,792 km per second! How mental is that?! šŸ’Ø
      Iā€™m sure somewhere in the šŸŒ someone is working on changing that though!
