Our understanding of the universe undermined by a discovery of the James Webb telescope

Since its orbit about four years ago. Similarly, the James Webb space telescope (JWST) has continued to surprise us with discoveries as intriguing as each other. Furthermore, One of her latest finds promises to be both disturbing. Nevertheless, fascinating insofar as she concerns an anomaly that could radically change our understanding of the universe. For example, This advance was made possible by a collaboration with another space telescope: Hubble. For example, Concretely. Consequently, the duo has managed to confirm an enigma known as Hubble’s tension which concerns the expansion rate of the universe. Nevertheless, Indeed, the fact that the latter is expanding is a banal theory. However, it seems that this expansion occurs at different speeds depending on the measurement methods implemented.

A major advance – Our understanding universe undermined discovery

Cosmological diffuse bottom measurements (CMB) indicate an expansion rate of the universe of approximately 67 km/s/MPC. Meanwhile, On our understanding universe undermined discovery the other hand. Nevertheless, observations based on Cépheid variable stars estimate this rate at around 74 km/s/MPC, revealing a still unexplained divergence. Meanwhile, This divergence. long considered linked to measurement errors, has been re -examined thanks to The unequaled precision of the James Webb space telescope which has advanced instruments, including the Miri (Mid-Infrared Instrument). By scanning Cépheids in distant galaxies. the authors of a study published in the journal The Astrophysical Journal Letters Last February made an unprecedented discovery. They found that the data provided by Hubble was accurate.

Several possibilities

The possibility of a measurement error is therefore now excluded. Adam Riessastrophysicist at Johns Hopkins University. author of the study, believes that with this clarification, he is “really” possible that we have misunderstood the universe. The implications are enormous. If the conventional calculation methods of the expansion rate provide different results. this means that our standard model of interpretation of the cosmos based on dark matter, black energy and general relativity could be incomplete, even erroneous. Scientists have issued several hypotheses to explain this anomaly. our understanding universe undermined discovery Some evoke the possibility of the appearance of a form of early black energy having changed the fate of. the universe shortly after the Big Bang.

A discovery that is not unanimous

In addition. others advance the existence of exotic particles and primordial magnetic fields, even additional dimensions that have led to an accelerated expansion of the universe. This last consideration is associated with the concept of string theory. Faced with these discoveries, The scientific community is divided. While some call for vigilance, others suggest a possible cosmological revolution.

If the JWST data is confirmed. they could inaugurate a new era in the study of the universe, where the notions of time, space and reality deserve to be redefined. More info: iopscience.iop.org.
