  1. I think purpose of life depends on the frame of reference. The more we level down, the more meaning there is. Cosmically we are insignificant. In our small family groups and by ourselves, we find meaning in many things. Also religion, spirituality or lack thereof play a part. If you don't believe in anything after death, there is little meaning to living other than the continuation of the species (o your family line). But that is only relevant in the local frame. Aliens on a planet 8 billion LY away don't really care if we exist or not.
  2. I have a question from the following statement in this article that I can't understand. How can our speed traveling in time be the speed of light? I realise our measure of time, such as seconds, minutes, is purely artificial, so how is our movement through time measured? For anything travelling at the speed of light, you would need infinite energy to accelerate the object to light speed. I don't see an infinite energy propelling my desk or me to light speed. What's going on here? "We know through the physics of Einstein's special theory of relativity that you can trade motion in space for motion in time. If you're standing perfectly still, you're moving through the dimension of time at a particular speed (the speed of light, for those of you who are curious)." https://phys.org/news/2020-05-future-totally.html Here's a bonus question - time decreases the faster you get, and the examples given are always straight linear motion relative to an observer. What if you put a moving observer inside a cyclotron - he sits in the middle (not spinning), and the cyclotron spins around him at the speed of light. Would time stop for him, or does he physically need to me moving/spinning.
