Context. Within the frame of the $\Lambda$ cold dark matter paradigm, a dark energy component of unknown origin is expected to represent nearly 75% of the energy of the Universe. Aims. To provide new grounds on which alternative cosmologies could be developed. Methods. A new form is proposed for Hubble’s law. Its consistency with observational data of various origin is checked. Results. This Hubble-like law yields an age-redshift relationship which is consistent with available data. Together with a non-standard distance-duality relationship, it provides an alternative interpretation for both angular-diameter and luminosity distance data. Conclusion. Along this line of thought, there is no need for a dominant energy component of unknown origin.
