HELIUM ABUNDANCE. “Now we know that stars cannot build up the observed He abundance through nuclear reactions in their interior, and thus have to be primordial.” https://royalsocietypublishing.org/doi/10.1098/rsta.2019.0091 View in LinkedIn

COSMIC LABORATORY. “The early universe can be used as a probe of fundamental physics at much higher energies than those explored in the present universe.” https://royalsocietypublishing.org/doi/10.1098/rsta.2019.0091 View in LinkedIn

Fungi are more closely related to humans than to plants, but are so diverse in form and lifestyle they might as well come from outer space. View in LinkedIn

NEVER FORGET THIS. “99.9% of all species that have existed are extinct (Raup, 1986)”. https://lnkd.in/dsrys6uc View in LinkedIn

AN ISSUE OF COSMIC SCALE. “An analogous situation can be realized in heavy ion collisions at CERN, although boosted to much larger energies and densities. Such a dense and hot shock wave will induce high-energy processes that can only be realized in the very early universe. https://royalsocietypublishing.org/doi/10.1098/rsta.2019.0091 View in LinkedIn

GRAVITATIONAL COLLAPSE is “similar to the shock that blasts the outer layers of a star when it explodes as a supernova, except that here the surrounding plasma is extremely dense and thus ultra-high-energy interactions occur very frequently.” https://royalsocietypublishing.org/doi/10.1098/rsta.2019.0091 View in LinkedIn

BEYOND EXPLOSIVE. “The gravitational collapse of a ball of radiation the size of the horizon at the QCD epoch onto a black hole of a solar mass is an extremely violent process, where a very dense plasma of relativistic particles acquire energies thousands of times their mass out of the gravitational potential energy of the collapse.” (QCD = quark matter). https://royalsocietypublishing.org/doi/10.1098/rsta.2019.0091 View in LinkedIn

MATTER FROM BLACK HOLES. “Baryogenesis is somehow linked with PBH formation and that the reason why the observed BAU is so small is due to the extreme rarity of the number of Hubble domains that collapse to form PBH, which is itself responsible for a late matter domination after equality.” (PBH = primordial black hole; BAU = baryon asymmetry). https://royalsocietypublishing.org/doi/10.1098/rsta.2019.0091 View in LinkedIn

BIG PROPOSAL. “The third prediction is that these sort of primordial black holes constitute at least 20% of dark matter.” https://lnkd.in/dQ9VgzAr View in LinkedIn
