Zap Ultra-dense Deuterium with a laser as an alternative.

Not 54 but only (ha, ha) one billion light years away. So this happened one billion years ago.

How far can light travel in one year?

Approximately 5,878,499,817,000 miles. That’s almost 6 trillion miles.

And it took this explosion a billion years to reach us.

Blows the mind, doesn’t it? A lot of the stars we see don’t exist anymore while other stars exist whose light hasn’t reached us yet.

Fusion power is the way of the future.

The sooner we get it, the better.

“Fusion power is the way of the future.

Fission is fine, and actually works now. Fusion won’t have clear advantages for a very long time, since the deuterium/tritium reactions all produce neutrons, meaning radioactive waste.

Fission still provides a million-fold improvement in energy density over chemical power, has a plentiful fuel supply, and will be 100% safe in the form of modern reactor designs, which also don’t require water cooling.

One important use of nuclear energy will be in space, including exo-atmospheric propulsion.
