smoke detector went off while I was dusting it- set offall the others.Aren't you supposed to dust round them!
The 2D picture of the 3D fabric of SPACE is a stretched rubber sheet, not a bowl. It is like the bell of a trumpet. Massive objects are placed on the rubber sheet and deform the sheet. The deformation is a complex curve most nearly like a hyperbola at the top and a parabola at the bottom. The slope of the curved space is steepest at the object and approaches horizontal as you move away from the object. The depth of the curve is a function of the mass of the object. In the case of Black Holes, the curve goes vertical. at the Black Hole. What exactly gravity is still unresolved. How a force acts at a distance has not yet been figured out. Both Newton and Einstein described gravity without being able to say what it is or how it works. We know what it does, but we don't know how it does it.
don't use tinted shields at night. I also don't recommend the high viz orange type shields at night. you CAN get away with riding with it as i have, but it make the light sources look very odd, so i don't recommend it. if you know you're going to get caught by going from day to night or night to day, bring the appropriate shield with you. personally, i prefer the high viz orange shield instead of a grey tinted type shield. the orange helps makes things stand out and give it a crisp view. i much prefer it. it doesn't look cool, yeah i know, but i like that through my eyes, the visuals are better than a grey tinted screen.
HJC is a good brand for a low cost. I have one and it is a good helmet. Also, under 100 bucks is not enough money. It will be over a 100 bucks but not over 200. try them on. it should fit snug so you grab the front and move side to side it does not move without your head moving. You want it to move your head with it. no slop.
