Is the idea of a static, infinite universe still alive?

I know Einstein initially believed in a stationary universe. But do any serious cosmologists today still entertain the idea of a static, infinite cosmos?

No. The evidence is overwhelming and unanimous. Hubble's law shows galaxies receding from us. The cosmic microwave background is a direct fossil of an initial hot, dense state. Einstein called his "cosmological constant" his biggest blunder precisely because he missed predicting expansion. A static universe is a historical artifact, not a live hypothesis. We live in a dynamic, expanding cosmos that began.
