✍️ About : Dark Energy can not be negative yet it has been shown that a negative cosmological constant can solve the Long standing problem of Hubble Tension and S8 tension. In the paper titled "Do cosmological observations allow a negative Cosmological Constant" authored by Dr. Anjan Ananda Sen, one of the leading cosmologist found that a negative cosmological constant happen to be a better fit with cosmological observables " like CMB, SHOES, Pantheon Data sets. It opens new perspective of thinking theoretically to attack this mysterious problem of Dark Energy.
