@elonmusk Time is a feedback loop. The past, present and the future are all happening simultaneously according to Albert Einstein and quantum mechanics. The future can influence the present, the present can influence the past and so the past can influence the present. Time isn’t linear.
@XplusMe@DefiyantlyFree The X and Y chromosomes, also known as the sex chromosomes, determine the biological sex of an individual: females inherit an X chromosome from the father for a XX genotype, while males inherit a Y chromosome from the father for a XY genotype (mothers only pass on X chromosomes)
