Exploring Other Dimensions and Bat Biology

Helsingin Sanomat delves into the fascinating realm of theoretical physics and biology, tackling complex questions posed by young minds. The article addresses the profound query about the existence of other dimensions and universes, exploring concepts like parallel worlds and wormholes as discussed in scientific theories.

While acknowledging the imaginative appeal of these ideas, the piece grounds the discussion in current scientific understanding, stating that no empirical evidence currently supports the existence of other universes. It touches upon theories that posit the universe might branch off into inaccessible parallel worlds, adding a layer of scientific intrigue without making definitive claims.

Some physics theories consider other worlds possible, but there are no scientific observations.

Furthermore, the article provides a clear and accessible explanation for a common curiosity: whether bats suffer from blood rushing to their heads when hanging upside down. It details the biological adaptations, such as specialized valves in their blood vessels and their small size, that prevent this issue. This dual focus on cosmic possibilities and the biological intricacies of everyday creatures showcases Helsingin Sanomat's commitment to engaging readers with both the grand and the minute aspects of science.

Bats do not get blood in their heads when they sleep upside down. For us humans, it is not the most comfortable position to rest, because blood does tend to pool in the head and makes us feel sick.
