Terveiset Stephen Hawkingille!
Miten saamme tämän uuden infon Stephen Hawkingille?
Kertokaapa terveisiä Enqvistille, Tähtiselle, Valtaojalle ja muille tutuille tieteen parissa työskenteleville.
On oikeus ja kohtuus etä Stephen Hawking vihdoinkin kuulee miten maailmankaikkeus oikeasti toimii.
Tässä video siitä miksi pysymme tukevasti Maapallon pinnalla ilman vetävää voimaa.
If you wonder how we can stay firmly on the surface of the globe, please
remember these five things:
1. Pushing away from the centre of the globe
2. Internal pressure
3. External pressure
4. The interaction of the energywaves
5. Decreasing of the external pressure
Constant pressure inside the globe is due to continuous expanding of the
atoms and this pressure bursts out so that the expanding atoms push
themselves away from the centre of the globe at the same respect as they
The particules opening up from the globe are smaller than the energybundles
coming from the space. So the energybundles coming from the space get more
hits while moving in an area between the atomcores and that is why the
external pressure is stronger. (Please, see also the videoclip "How does the
kinetic energy transfer")
The energywaves coming towards the globe spread because the energybundles in
these waves push themselves away from each other. Also the globe expands.
Energybundles that expand approach the globe and open themselves
energywaves, by which they push themselves away from each other.
If the energybundles coming from the globe do absorb the energywaves opening
up from these particles with itself, then this wave will not spread so
quickly and the external pressure is then stronger. On the other hand, it is
possible that the energybundles coming from the globe make the energywaves
to spread faster and the external pressure is then smaller.
External pressure decreases the further one goes from the globe. The globe
stops to itself the energywaves that come behind the globe. The further one
goes from the globe, the more energy reaches the subject from behind or from
the sides of the globe. Dies the external pressure decrease four times
smaller when going two times further from the globe?
