科学家宣称人类发明了世界上最轻的固态物质,这一物质能置于蒲公英的顶上,并且不压碎任何一粒种子。目前,世界上最轻的物质由美国科学家发明,这一物质由空心的金属管制成,这一空心管的内壁比人的头发丝还要轻1000倍,这些空心管以纵横交错的对角线形式呈现,管与管之间留有很多微小的开放空间。研究者们声称,这一物质99.99%由空气制成,比聚苯乙烯泡沫塑料(目前
Scientists claim that humans have invented the world’s lightest solid substance, a substance that can be placed on top of a dandelion without crushing any one seed. At present, the lightest substance in the world was invented by American scientists. The substance is made of hollow metal pipe. The inner wall of the hollow pipe is 1000 times lighter than the human hair. The hollow pipes are arranged in a crisscross pattern of diagonal lines Form of presentation, leaving a lot of small open space between the tube and tube. The researchers claim that 99.99% of this substance is made of air, much less than Styrofoam
