We find that the SMC was already forming stars ~12 Gyr ago, even if the lack of a clear horizontal branch suggests that in the first few billion years the star formation activity was low. | |
These findings will help to constrain the formation of massive stars. | |
Following the recent finding by Bastian that galaxies form, on average, 8% of their stars in bound clusters regardless of their star-formation rate, we raise the hypothesis that star formation in the present-day universe is characterized by a near-universal distribution of the local SFE. | |
We conclude that strong magnetic fields are generated during the birth of the first stars in the universe, potentially modifying the mass distribution of these stars and influencing the subsequent cosmic evolution. | |
Not only is the detection of early star-forming objects vital to understanding the underlying cause of the reionization of the universe, but the timely discovery of a z > 7 star-forming population—or even an interesting upper limit on the emergent flux from these objects—will have implications for the design of the next generation of ground- and space-based facilities. | |

What is the crisis in cosmology?5 answersThe crisis in cosmology is characterized by two main anomalies. Firstly, the lensing amplitude in the Cosmic Microwave Background (CMB) is larger than predicted by the ΛCDM model, suggesting a higher density of the Universe than expected. Secondly, there is a significant discrepancy in the measurements of the Hubble constant, with different methods yielding remarkably different values. These issues have led to debates and discussions within the cosmology community, questioning the validity of current theories and models. Some scientists have expressed concerns about the reliance on hypothetical entities, such as inflation, dark matter, and dark energy, in the big bang theory, which may contradict observations and raise doubts about the theory's validity. Additionally, conflicts between the General Theory of Relativity and the Big Bang model have been identified, further challenging the prevailing cosmological framework.
When will humans land on Mars?5 answersHumans are planning to land on Mars in the 2030-40s. The government of Dubai has announced plans to create the first human settlement on Mars within one hundred years. There are vehicle designs and a mission architecture that were developed in the 1990s to send humans to Mars. Mars exploration missions in the future will focus on Mars Sample Return (MSR) and sending humans to explore Mars in late 2028 or early 2030. Current NASA planning envisions human missions to Mars as early as 2013.
When does penis growth stop?5 answersPenis growth stops at different stages depending on the age group. In children and adolescents aged 0-16 years, the length and diameter of the penis grow rapidly before the age of 1 year, grow relatively slowly from 1 to 11 years old, and enter a rapid growth period from 11 years old. In humans, the mechanism that stops penile growth is not the down regulation of the androgen receptor. Men over 50 may experience a decline in sexual potency, physical potency, and intellectual potency, which is analogous to the menopause but does not involve profound hormonal changes or loss of reproductive capacity. Progressive decline of serum free testosterone levels occurs at a rate of 1% per year after age 40, with an estimated 20% of men aged 60-80 years having levels below the lower limit of normal. Reference values for penile length in Japanese boys aged 0-7 years have been established, showing continuous growth during the prepubertal period.
When will the human race become extinct?5 answersThe human race is predicted to become extinct within several million years. Factors such as germ warfare, environmental collapse, or other unknown factors could potentially drive humans to extinction in the near future. However, if humans were to spread across the galaxy, their chances of survival would still be low. Despite this, efforts should be made to increase the likelihood of galactic colonization and resist the notion that human extinction would be inconsequential.
