One theory that has been forward as an alternative view of the Big Bang, is the Big Bounce. This states that rather than a singular event that has lead to the universe expanding, it was actually a bounce from an earlier universe which contracted and then bounced back But it has been argued that the laws of quantum physics means that this would not have been possible. https://www.newscientist.com/article/2488654-the-laws-of-quantum-physics-rule-out-a-universe-that-came-before-ours/

If we could live forever, imagine drifting through the endless vast sea of the cosmos for billion of years. Not staying in one place but always moving. Of all the things we would have seen.

I'm excited to learn more about this visitor.

Warp speed is some time away, but we are making progress. Fancy a trip to Mars?

A galactic masterpiece: a stunning image of NGC 253 has just been released by ESO @esoastronomy. If you're wondering where it is located in our cosmic neighborhood, here it is indicated in a map from our Cosmography of the Local Universe paper.

Cool

Astronomers locate universe's 'missing' matter

The #universe has 2 kinds of #matter. There is invisible #DarkMatter, known only because of its gravitational effects on a grand scale. And there is ordinary matter such as gas, dust, stars, planets & earthly things like cookie dough & canoes.

How an infinite world may be built up

Chinese astronauts add debris shield to Tiangong space station during 8-hour spacewalk

https://www.space.com/space-exploration/human-spaceflight/chinese-astronauts-add-debris-shields-to-tiangong-space-station-during-8-hour-spacewalk-video

Przez trzy noce polowałem. Polowałem na dziury w chmurach.
Pierwsza noc to zaledwie 20 minut, drugiej nocy wyszło około 1h17m. Z prognoz pogody wychodziło mi, że z 31.05 na 01.06 nic się nie da wypalić, bo chmury i deszcz. Po północy okazało się, że niebo jest czyste i szybko wystawiłem i ustawiłem sprzęt. Z odpalonym antistorm.eu i WheatherRadar i sprawdzaniem co chwilę wszystkiego naocznie, dopaliłem 1h45m.
Z całości Siril złożył 548 klatek po 20 sekund, czyli nieco ponad 3 godziny.
Przed Państwem The Eastern Veil Nebula[1] aka NGC 6992 aka Ksenomorf. ;-)

#Science tells us that everything we know in the #universe is changing. In fact, we believe the physical universe itself is expanding. So why do we assume (or have reason to believe) that its #laws have been static since the origin we call the #BigBang? #space #physics #autaxys

#Autaxys aims to provide a comprehensive framework for understanding #reality, encompassing the physical #universe, the emergence of #life and #consciousness, and the #nature of #knowledge itself. https://qnfo.org/releases/2025/New+Way+of+Seeing/_New+Way+of+Seeing

Zerknąłem na prognozy pogody i wychodzi na to, że w tym miesiącu już nie wyprowadzę Seestara na spacer. Pod kątem astrofotografii maj mogę uznać za zakończczony.
Dodajmy, że zimny i pochmurny maj, więc szału nie ma.

Co udało mi się sfotografować?
Voilà!
– Galaktyka Sombrero (M104)[1] - najwięcej materiału; 853x20 sekund, czyli prawie 4h 45m.
- galaktyka NGC 2403[2]; 809x20 sekund, czyli prawie 4h 30 m.
- galaktyka M108[3] - 456x20 sekund;2h 32 minuty
- galaktyka M109[4] - 303x20 sekund; 1h 41 minut
- galaktyka NGC 3521[5] - 243x20 sekund; 1h 21 minut
- M40[6]- w sumie to nic ciekawego, ale zaliczyć trzeba; gwiazda optycznie podwójna; 97x20 sekund ; niecałe 22 minuty.

- TON-618 ale o tym już było.

Wrzucam jako kolaż cropów . Jeśli ktoś chce zobaczyć całe zdjęcie to niech napisze. ;-)
