The scale of the universe. It's an incomprehensible amount of emptiness.
Highly recommend the browser game Orbity.io
I just played it, such a fun game. Not exactly what I thought it was going to be when it come to the infinity of space
It honestly pisses me off lol. I was so into space as a youngin but as Ive gotten a better grasp of the scale and what is actually possible in physics Ive realized its a massive boondoggle. Real pretty though
I still refuse to believe that we can't overcome the limit of the speed of light. Maybe it's something like "warpspeed", maybe it's something like evolving beyond the need for a physical body, but I believe that at some (far) point in our future we will solve that problem.
Speed of light is a bit of a misnomer, its really the speed of causality; the least amount of time it can take for one thing to interact with another. It will never be possible to overcome that limit unfortunately
Nah, itβs impossible with our current understanding of the nature of the universe and itβs rules. Every time that has been true of something, humanity has eventually either solved the problem or rendered it moot. This one may just take a while.
Respectfully disagree. The math speaks for itself
How shortsighted.
Its shortsighted to trust math?
You should look into the effects on causality of going faster than the speed of light. If you can send information faster than the speed of light all kinds of wacky paradoxes show their heads. I used to believe what you did, that with time and knowledge we could overcome the speed of light. But after learning more about our universe I don't think that's the case anymore. I enjoyed this video on the topic https://youtu.be/an0M-wcHw5A

A fact I've recently enjoyed spreading around: all of humanity's radio communications have traveled about 200 light years from Earth. The diameter of the Milky Way galaxy is ~100K light years. So (in the worst case) we're like 0.2% of the way to even being a "blip on the radar" of any alien life within our galaxy.
Also interesting is that because the energy of those signals is spreading out as they move away from their point of origin they become less detectable as they travel. Most signals would fall below practical detection limits before making it halfway to the nearest star. At the extreme, the Arecibo Message, transmitted with a ridiculous ERP, will be detectable to reasonably sized receivers for tens of thousands of light years, assuming they are located along the path of the beam.
