Cosmology in Crisis

Abstract

Standard cosmology is in crisis. There are a lot of anomalies but two of them have received special attention recently. The most recent anomaly is due to the findings that the so called lensing amplitude in CMB is larger than Λ CDM predicts. This suggest that the density of the Universe is 5 per cent higher than the critical density so that Universe should closed rather than flat and infinite. Second anomaly is old: depending on measurement method one obtains two values for the Hubble constant differing remarkably. The debate about this has continued for decades and continues still. In this essay, the two above mentioned problems regarded as crises are discussed in terms of TGD view about space-time.
