At the subatomic level, space is never truly empty. It is filled with a writhing, active population of “Virtual Particles” that pop in and out of existence. Physicists call this “quantum foam”. Physicists theorize fluctuations from this field of energy may have given rise to the Universe.
Timeless physics is the controversial view that time, as we perceive it, does not exist as anything other than an illusion. Arguably we have no evidence of the past other than our memory of it, and no evidence of the future other than our belief in it.
One evening in 1954, in a student hall at Princeton University, grad student Everett was drinking sherry with his friends when he came up with the idea that quantum effects cause the universe to constantly split.
Physicists at Washington State University created ‘negative mass’ where unlike every known physical object in the world, it doesn’t accelerate in the direction it was pushed. It accelerates backwards.
Sniper bullets can travel so far that the rotation of the Earth will move the target, and shooters have to adjust their aim accordingly.
Due to time dilation one could travel thousands of light years in a human lifespan without exceeding the speed of light. A full 40 year trip at 1 g will appear on Earth to last 58,000 years and cover a distance of 55,000 light years.
If the strange matter hypothesis is correct, it is speculated that a strangelet coming into contact with an ordinary lump of matter could convert the ordinary matter to strange matter. In a disaster scenario, all the nuclei of all the atoms of Earth are converted, and Earth is reduced to a hot, large lump of strange matter.
Chadwick (the discoverer of the neutron) was a student of Rutherford (discoverer of the proton) who was the student of Thomson (the discoverer of the electron).
It takes a photon 170,000 years to travel from the core of the sun to the surface, but only 8 minutes to travel the rest of the way to earth.
