Was Poland in the Warsaw Pact?
The Warsaw Pact was a collective defence treaty established by the Soviet Union and seven other Soviet satellite states in Central and Eastern Europe: Albania, Bulgaria, Czechoslovakia, East Germany, Hungary, Poland and Romania (Albania withdrew in 1968).
Who gave France nuclear weapons?
France began its nuclear weapons program in the early 1950s in an effort to restore political and military parity with their perceived peers and potential adversaries. In the wake of the United Kingdom and Russia acquiring nuclear capabilities, France moved quickly and produced its first plutonium bomb on July 1, 1963.
How many nukes do France have?
300 nuclear warheads
What happens if I touch antimatter?
When antimatter and regular matter touch together, they destroy each other and release lots of energy in the form of radiation (usually gamma rays). If it’s a small amount, it’s totally safe. If it’s a large amount, the gamma radiation would be enough to kill you or cause serious harm.
What would happen if antimatter hit a black hole?
No. Antimatter has positive mass just like ordinary matter, so the black hole would merely get larger and heavier. Whatever fireworks happened inside the hole, if the anitmatter met up with ordinary matter there, would have no effect on the hole’s total matter-and-energy content or, therefore, its mass.
What would happen if antimatter hit Earth?
Whenever antimatter meets matter (assuming their particles are of the same type), then annihilation occurs, and energy is released. In this case, a 1 kg chunk of the earth would be annihilated , along with the meteorite. There would be energy released in the form of gamma radiation (probably).
What does antimatter look like?
When you see antimatter depicted in science fiction movies, it’s usually some weird glowing gas in a special containment unit. Real antimatter looks just like regular matter. Anti-water, for example, would still be H2O and would have the same properties of water when reacting with other antimatter.
Why antimatter is so expensive?
Due to its explosive nature (it annihilates when in contact with normal matter) and energy-intensive production, the cost of making antimatter is astronomical. CERN produces about 1×10^15 antiprotons every year, but that only amounts to 1.67 nanograms.
Can antimatter destroy the world?
Will the mutual annihilation and conversion to pure energy destroy the world? No, say physicists. “It’s true that when matter and antimatter meet, they do annihilate in a big explosion and convert their mass to energy.
What is the proof of dark matter?
Primary evidence for dark matter comes from calculations showing that many galaxies would fly apart, or that they would not have formed or would not move as they do, if they did not contain a large amount of unseen matter.
Is there any antimatter left?
For the past 50 years and more, laboratories like CERN have routinely produced antiparticles, and in 1995 CERN became the first laboratory to create anti-atoms artificially. But no one has ever produced antimatter without also obtaining the corresponding matter particles.
