Read more about A 107-year-old Einstein theory about how the universe began, Which is 100% correct.
The large-scale structure (LSS) of the Universe is obviously nonlinear and very complicated. However, the scale of onset of nonlinearity is well separated from the size of the Universe which makes a large portion of the structure formation modes accessible to perturbation theory (PT). The latter is itself complicated by the time dependence of the lambdaCDM background. The authors provide an exact all-order recursive solution for the PT kernels, which allows them to go beyond the Einstein-de Sitter approximation for the time dependence, and quantify the deviation at the two-loop level in the 10% range, a deviation detectible with upcoming observations.
The last event of 2022 will take place December 19th: Christmas Special meeting. with our president Prof. Bernard Foing!
We’ll have a look at what we have done in 2022, and we’ll announce the program of 2023.
The Zoom meeting will be open to all of the SRI Members and invited friends – just registered or going to register during the meeting.
All the participants will have the possibility to make questions to the SRI President, the Founder and the Board of Directors, about the 2023 program. Criticisms and proposals will be welcome too.
We have a huge programme for 2023, and we are going through some key steps, to achieve an higher legal status for our association: to be registered as a not for profit entity on the Unic National Register of the Third Sector Entities (RUNTS). Such an achievement will allow SRI to call Italian taxpayers to target the 5×1000 of their yearly tax to SRI, and the donations to be deducted from the tax declaration. These conditions, when achieved, will greatly contribute to the sustainability of our initiatives.
We are asking each of the SRI members and supporters to assume this priority for December 2022: to bring onboard many new members and to seek for donors and sponsors!
We will celebrate together during the Xmas Special event and exchange season greetings and wishes for a vibrant year 2023 for Space Renaissance International!

Two planets that astronomers discovered on the Kepler mission may not be the rocky, Earth-like bodies that we originally believed. Instead, a new study suggests that they could be two water worlds, and that they are less dense than astronomers originally posited. What’s intriguing about these worlds is that they are believed to be somewhat similar to Europa, which is a rocky core encased in water and capped in ice.
The past and the future are tightly linked in conventional quantum mechanics. Perhaps too tightly. A tweak to the theory could let quantum possibilities increase as space expands.
Danuri, South Korea’s first deep-space exploration mission, is finally arriving at the moon after a four-month voyage.
The Danuri spacecraft was expected to begin entering lunar orbit at on Friday (Dec. 17) at 2:45 p.m. EST (1945 GMT, 2:45 a.m. Dec. 17 in South Korea), according to a statement (opens in new tab) from the Korea Aerospace Research Institute (KARI). The maneuver, the first of five planned engine burns through Dec. 28 to refine Danuri’s orbit around the moon, will clear the way for the probe to get started on its lunar science objectives.
So far the mission has produced information on Io, Ganymede and Europa.
NASA’s Juno mission already brought us much data on the moons Ganymede and Europa. Now, according to a press release by the agency published on Wednesday, the spacecraft is exploring one more of Jupiter’s moons: Io. Io is notably the most volcanic place in the solar system.
