There is still quite a bit of science we haven't figured out, and it's actually the basics. it's likely the key to unlocking our understanding of everything in the universe but we appear to be far off from figuring it out. for example, here's 4 things that seem connected that humans do not understand: - Gravity - we have no idea what it is, how it works, how to create or destroy it, or even why it exists... we only understand that it's real and we can only assume it exists because we see the effects of it and we have a way to measure an effect of it.
- Light - we have no idea what it is, how it's made, or how it works, we don't know how it travels we only know what we visually observe that there is light and it's visible... we think we can measure it's speed but that's not certain.
- Dark Energy and Dark Matter - no clue what these are, where it can be found, how it works, how to observe it, how it relates to other things such as light and gravity. we are pretty sure they exists but have little proof, some ideas think it's absence of energy, others thing it makes up the majority of the universe. it may be a web or stuff.
- Time - no clue what this is, can explain concepts about it, but we're not sure if it's real, if it means anything, if it has any influence on other forces, can it be controlled or stopped, or circumvented.
Likely we won't be able to solve these here on earth. we are like an ant trying to validate Saturn's existence from inside the ant farm. the ant can have ideas but no way to validate without getting out and exploring.
This is why astronomy and space are so interesting to many; it's quite likely that branch of science is the key to getting these answers which could then unlock what seems impossible to us today.
alright, someone take away my nerd mic now please.  |
We don't know what
Light is? It's photons. We know a ton about light aka photons. Including that it has no mass, and therefore its speed is the fastest in the known universe as other matter has mass and therefore slowed down.
Gravity we don't know whether there is a particle/force that is responsible for it's effect, but we believe there probably is but we cannot isolate it at this point as we think we cannot make sufficient energy to produce the particle.
Dark energy and dark matter are generally unknowns but we are very confident they exist but as they do not interact with normal matter, they only interact with "gravity" so we cannot know many of of its other features
Time - that one's tough but if you know about the theory of general relativity it is affected by mass, gravity, etc.
